‘Kong’ has grown to 360 lbs. It is now my PB (personal best), still putting on weight and looking good. I wonder what it will end up at. I’m going to the Oct 2 Giant Pumpkin Commonwealth (GPC) weigh-off in Colorado Springs, CO. The New Mexico State Record is 404 and with this warm weather I have a chance to break it. A long shot but still a chance. So put a word out to the universe asking for Kong to break the state record! GROW KONG GROW!!!

‘Kong’ hits 278 lbs..
‘Kong’, my only giant pumpkin left, hit 278 lbs tonight. (I’m putting ‘Harpie’ in the NM State Fair tomorrow-it was much smaller at around 100 lbs). If ‘Kong’ can put on 6 lbs a day till the weigh-off, I can beat the current New Mexico State Record. It’s been putting on 8-12 lbs daily for awhile but I know it will slow down to a crawl this month. Hopefully I still have 2 or more weeks of good weight gain before the crawl. Grow nagua, grow…
Giant pumpkin ‘Kong’ hits 228+ lbs!
Here is a mini slide show of ‘Kong’, my biggest giant pumpkin right now. There is an apple on it for perspective. Kong is 35 days old and 228 lbs as of tonight. It’s been putting on between 12-17 lbs a day. I said a day! 17 lbs is the best weight gain in a single day I have ever had with a giant pumpkin. I know others have greater gains but we have harsher conditions and shorter growing season here. Kong is starting to get longer and bumpier. I like its looks! I love going out after work and measuring them every evening. You can actually see a difference from day to day. It is mind blowing!
‘Harpie’, my other big pumpkin, is beautiful, being perfectly round and not gnarly like Kong. It is at 100 lbs and its weight gain varies from 4-10 lbs a day. I will post pictures of it later.
It has been around 47 degrees during this past week so I have to put a blanket on both of the pumpkins over their row cover so they don’t loose so much heat at night. The pros say to blanket them when the temperature gets below 60 degrees at night. That way they don’t have to wait to warm up in the morning to continue growing. The row cover is to provide shade during the day (think like a light weight covering) so their skins don’t get hard. It is easier for them to grow when their skin is soft.
This is my pumpkin mantra, “Grow Naguas, grow” (grow pumpkins, grow). I say it everynight when leaving the pumpkin patch!
Master Gardeners tour-Giant Vegetable Garden
I’ve been getting ready for my first Giant Veggie Garden Tour for the Santa Fe Master Gardeners group next Sunday from 9am-12 noon. I have 3 giant marrows, one being around 30+ lbs, 2 giant pumpkins, many giant sunflowers, and a couple of giant tomatoes (still green). I’m cleaning up, trimming and generally sprucing up the garden. By the time they come next Sunday I should be ready. Seems like there is always something to do in a garden no matter the size. Fall is definitely in the air with the nights cooling off into the high 40-50s. Daytime temperatures are in the 80s. Perfect weather to be in the garden…
N. Harp and Grande pumpkins
As Christy Harp, the new giant pumpkin world record holder (1725 lbs) once said, “Growing giant pumpkins-it’s not a hobby, it’s an obsession!” I have to agree because once you get some growing, it is so much fun to watch and I mean literally! The first photos are of my biggest on the N.Harp plant. Look how round it is.
The other pictures are of my biggest pumpkin from the Grande 895 plant. Look how oval it is. I’ve shown the beginning pic and current pic-they are pretty much the same shape as when I first pollinated them. When I went out the other evening and measured those pumpkins, the 895 Grande had put on 3.5 inches in girth from the evening before. That’s in 12 hours. I have more pumpkins coming on but those 2 are my biggest and are now 20 and 25 lbs-small for giant pumpkins but they are only babies and will grow extremely fast in August and September. I haven’t named them yet but will this week. (yes I name them. Any veggie you grow for 5-6 months and grows this fast deserves a name) It has begun..
Baby giant pumpkins are putting on weight
I actually measured the baby pumpkin on the N. Harp main vine yesterday and today because it is starting to grow (at least for now). It is about the size of a soccer ball now. Circumference was 27″ yesterday and today it was 28.5″. A gain of 1.5 inches in 24 hours . This evening I measured using the OTT method which is more accurate and Harp’s total measurement was 51.5 and the 895 Grande main was 47 OTT. The measuring chart doesn’t go down that low so I’m not sure how much they weigh yet but should sometime this week as they start to really grow.
Giant Pumpkin Sex 101a
Ok, here’s the skivvy on giant pumpkin sex 101. I’ve been talking about giant pumpkin pollination a lot and have been giving bits and pieces of info and so want to be clear about WHY we choose to pollinate them and HOW we hand pollinate giant pumpkins.
First WHY do we pollinate them?
If I was growing regular pumpkins I wouldn’t pollinate them, I’d just let the bees do it but giant pumpkin growers want to know what genetic material is being passed from the male flower to the female flower of a pumpkin. why? Because it doesn’t affect this season’s pumpkin, but the next year’s seeds of that pumpkin. That way we can grow bigger pumpkins, prettier pumpkins, oranger pumpkins, rounder pumpkins, etc. next year. If we let the bees do it, we wouldn’t know which pumpkin plant the pollen came from as the bees visit many flowers from many plants.
So we grow several different pumpkins from seeds from different giant pumpkin growers. For instance, I have 3 growing right now and one that I hand pollinated the other day was from the seed of a 895 lb pumpkin seed grown by a grower named Grande in 2009 (hence it is called an 895 Grande 09) and I crossed that female flower with the male flower from a seed of a 945 lb pumpkin seed grown by a grower named N. Harp in 2010 (hence it is called 945 N.Harp 10). Why would I do it? I’m trying to cross 2 top notched pumpkins and see what I can get. I hope to get a round really orange pumpkin with great weight. The 895 Grande was really pretty but the 945 N. Harp came from great genetics. I know which pumpkins they came from because those growers list that with their seed. I can also look up the grandparents as well. If we let the bees do it, we would not have this information to help us decide.
Second question is HOW we do we hand pollinate the female flower?
First all pumpkins produce both male and female flowers on each plant. The male flowers show up first and then the female flowers start showing up. I watch the closed green female flowers closely for when they start to get big and slightly yellow orange on the tip of the flower but the flower is still closed. When I see that, I know it will OPEN THE NEXT MORNING. So I cover it the night before and some male flowers as well so the bees won’t get to it first with unknown pumpkin pollen. Then I get up EARLY the next morning as we have a 4 HOUR
WINDOW TO POLLINATE THE FEMALE
FLOWER, (GENERALLY 6-10AM) and find some newly opened MALE flowers (or uncover the ones from the night before) from the plant I want to cross the female flower with. It could be from the same pumpkin plant or a different one. Now remember we can tell the female flowers because it looks like a little pumpkin is attached at the base of the flower while the male flowers are on skinny stems only. See pictures. Also the inside of male and female flowers are different and when the flowers are open you can see the differences. Male flowers have stamens (kind of look like a penis-I told you we would talk sex) that have the pollen on it which looks like grains of powder all over it. The female flowers have a stigma (think vulva) and if the timing is right (remember 4 hour time period) will accept the pollen from the male flower.
So as a giant pumpkin grower I take a male flower and peel off the petals leaving the stamen and take that flower and brush the stamen loaded with pollen like a paintbrush on the inside of the stigma and also around the outside of the stigma as well. Then I close up the female flower with a twistie so no other pollen can get in. I keep it closed for one day and take off the twistie afterwards and wait to see if the pollination takes which could take quite a few days. Sometimes they abort when they are a little smaller than the size of a basketball.
Inside each female flower are many immature eggs waiting inside immature seeds holding half the genetic material. The pollen holds the other half of the genetic material. If the female receives the pollen, the pollen will germinate and move down inside the stigma to the egg within an immature seed and fuse its genetic material with the genetic material of the egg stored in that immature seed inside that tiny pumpkin. PRESTO! FERTILIZATION has taken place. Every egg fertilized becomes a a viable future seed. And every seed fertilized holds the genetic material for a future pumpkin If not enough pollen as passed, the baby pumpkin will self abort. (or if it is too hot-90 degrees or hotter, they can abort too) COOL, HUH?! The so next time you need to talk to your kids about sex, you can talk pumpkin sex as an example!
Ok, have I given you too much info? I figure this way we won’t have to go over this again.!
Pumpkin female blossoms!
Last week I saw a bunch of male flowers, still small and closed but no female flowers. Yesterday I saw some baby female flowers with their baby fruit attached. Yea! Finally!
Yesterday I noticed the female blossoms are still small and closed but the male flowers are now blossoming and ready for the girls! There are two female blossoms on the main vines and 7 more on secondary vines. The picture on top is almost ready to open as the blossom is just starting to turn a subtle yellow color on the tip. In the other blossom pictures in this post, the blossoms are still very green and will open later. I will pollinate all of them when they are ready and see what I get.
Look how different the shape of the baby pumpkins are on the different pumpkin plants! The 945 N. Harp pumpkin flowers have round little pumpkins attached and the 895 Grande pumpkin flower has an oval shaped pumpkins attached. I think that is so cool that you can start to see the future pumpkin shapes even on the blossoms.
Even though the blossom looks like it has a baby pumpkin attached to it, it still needs to be pollinated which happens after the flower opens. Some will abort if pollination is not complete or if the weather is too hot. I hope the females open this week as the weather is suppose to be perfect for pollination-80’s all week. Not too hot. Anything over 90 is problematic for pollination.
Bri’s Giant Pumpkin Patch in
They’re in! The giant pumpkin plants are finally planted in Bri’s Pumpkin Patch. I rototilled the extra composted horse manure in and finished the low tunnels and put them in place Saturday in record breaking 99 degree heat here in Santa Fe. Brutal.
Sunday I planted my four baby giant pumpkin plants-949.5 N.Harp 09, 817.9 Schieder 09, 1166 Mohr 09, 895 Grande 08. I planted them at a 45 degree angle in the direction they will vine and up to the cots (baby leaves) so their stems will be protected from snapping off in wind. They are just starting to lay down so I built up the soil under them to support them. I placed them in the direction to grow out of the tunnels (remember to look at the second true leaf and that is the direction they will grow). I was worried that even with row cover over the top of the low tunnels, it would still be too hot for the baby giant pumpkin plants so I covered them with additional row cover. I had them in the windowsill but not outside to really harden off so I was afraid they would be really tender to the intense heat. I watered with Super thrive and seaweed fertilizer to help with the shock.
In addition, I went out and got some shade cloth to put over the row cover and to shade the ends. That should help with the temperatures expected to be in the mid to high 90’s the rest of the week. It ended up with much lower temperatures on Sunday- 86 degrees because a storm moved in all day and cooled things off and dumped some nice rain that night. Perfect planting weather! Not too hot. Nice lightning storm too.
I checked them last night after a 96 degree day and they are doing well what with all the extra protection. I still have to get in the drip system for the pumpkin plants but that should be easy the way I designed the patch. I also want to put a path around the patch to discourage people from walking through the patch and compacting the soil.
I also planted the last of the eggplants-Thai yellow egg and the winter squashes-Chiogga d’ Marina and Galeux de Eyesines seeds. Finally, I only have to get the corn in…almost there.
Time Lapse Growing Giant Pumpkin and High Speed Camera Explosion
This was so much fun I just had to share it. I found it on you tube. It came from www.billsbigpumpkins.com . It is also on my video page and currently on my sidebar as my featured video so others can find it after this post is buried.
giant pumpkins ready to go
Here is a picture of one of my baby giant pumpkins. The first leaves to come out on any plant are called cotyledons. These are the roundish ones in the picture growing on the left and right side of the plant. Notice how big they are! Most cotyledons are about the size of your fingernail. These are 3 inches across. The first true leaf is also out and is the biggest one in the picture as well as the beginning of the second one at the top of the picture. The vine will grow in the direction of the second leaf. This is good info to know as it will help you place the pumpkin in the direction you want it to grow (instead of into a fence). Notice the shape of them-they are the shape of all the rest of the leaves to come only smaller. When the leaves grow up they will be huge- 12-18 inches across! When the giant pumpkin have their first 2 true leaves, they are ready to go into the ground. Mine are ready but I’m not.
I have to partially rebuild my low tunnels that I will put the baby pumpkins in. A low tunnel is like a small hoop house only much shorter. They are meant as a temporary measure to protect the plants. I will cut them in half as I don’t think I need them to be so big this year. As soon as that happens, those puppies are going in the ground.
warm season veggies-here we come!
May 15th is fast approaching and is the average last frost date for Santa Fe and the time for putting your warm season vegetables in the ground. I sneaked some of mine in earlier but that is still a gamble in case we get one of those late frosts (we did) that plus the spring winds have been horrible this year. Never the less, I do grow some late season tomatoes that take 80-90 days to get fruit so I take the gamble on them and stick those transplants in early with the help of wall of waters and row cover. And of course my giant pumpkins take 5-6 months to grow so they need all the time they can get in the ground before that first fall frost hits even though I start them inside! So that takes care of the ones I sneak in early but what about the main vegetables crops?
For all summer squash, winter squash, cucumbers, beans, corn, I plant seeds directly in the ground (following directions on the package) as they will germinate quickly in the warm soil and will grow very quickly barring the birds from eating the seedlings. To prevent that, I put some LIGHTWEIGHT row cover (you can get it at the nurseries) over them until they are over the seedling stage and the birds aren’t interested anymore. It comes in big sheets but you can cut it up for smaller areas or it can cover the whole raised bed. Tack it down with some rocks so the wind doesn’t carry it away! Lightweight row cover is from -.01 to .03 in thickness. The handy thing is you can water right through it and it keeps bugs out.
For the majority of my tomatoes and all peppers and eggplants, I will transplant my plants that I started earlier inside or buy plants from the nurseries. When I plant them put them in a hole where I add some compost and maybe Yum-yum mix to get them going and create a well around them so the water is collected instead of running off.
So let’s talk tomatoes for a minute. Why? Well what is a vegetable garden without those homegrown, sweet tomatoes? Let’s face it, it is the main reason most of us have a vegetable garden. You want to put in tomatoes that are decent size plants. The reason being that they take a long time to grow to produce fruit and our season here is Santa Fe is so short that we need all the help we can get. Plus they take a long time to get them to a decent size which is very important to get that head start. So I started some in March and I also buy some. So as a rule of thumb, if I’m growing say an Oregon Spring tomato that takes 65 days to produce fruit, I might buy them in 4 inch pots but if I’m growing a Brandywine tomato that takes 80 days I will definitely spend the money and buy the gallon size. When deciding which tomatoes you want to grow, look at the amount of days it will take to get some fruit. When the tag or description says 80 days, that means it will take 80 days to become a mature plant that produces blossoms, and then it takes another 70 -80 days to produce mature fruit depending on pollination date. So let’s say a Brandywine plant is planted on May 15th outside, blossoms sometime in June-July, you should get some tomatoes 70-80 days later which puts us sometime in September! Why try to grow a tomato that takes that long? Flavor. The longer it takes, the better the flavor! They have more time to develop those sugars needed for great flavor. If I had a normal size garden (which I don’t but most of you do), I might try one or two of those longer varieties and I would try a few 65 day varieties and would have the bulk of my tomato varieties in the 70-80 day range. That way I hopefully will get some tomatoes early, mid and late season. That’s the thinking anyways!
So now you have everything up and growing what else can you do to help yourself get the best veggies? For one, I became a believer of drip systems a few years back after being a hand waterer for years. I put a simple drip system in and saw my yield at least double and it saves on water because it puts the water in the root zone. Another good reason for doing drip is that if you water from overhead, you could be encouraging some diseases from splashing the soil on them (there are soil borne diseases) or powdery mildew later in the season.
Next I would put a couple of inches thick of mulch in my wells (not in May when the soil is colder and your plants are trying to get warm) but by late June when it really heats up around here. Just put it over your drip system. This will help keep your water from evaporating. I like straw (not hay-it produces too many seeds) as it is lightweight and if you turn your soil over in the fall after harvest, it will break down for the next season. When you first put straw down, I do water it from the top so it won’t blow away and then let the drip work underneath it (so make sure it works before you cover it with straw).
So let’s talk fertilizer. I stay away from chemical fertilizers as they can hurt or kill your beneficial microbes that keep your soil healthy and help your plants grow and stay healthy. So stay away from Miracle Gro and the likes of that. I use more natural fertilizers-both organic fish emulsion and organic seaweed fertilizer together. The reason I use both is the fish emulsion is a general all purpose fertilizer but the seaweed has very little fertilizer but trace elements our veggies need to grow big and healthy. I put them together in a 5 gallon container and use it as a drench in my wells around the plants. Sometimes I also just spray the seaweed on the leaves for a foliar feeding. I fertilize once or twice a season except for giant pumpkins which get fed once a week. Believe it or not, as a giant pumpkin grower, they are the only fertilizers I use.
So what are you waiting for? Get busy and happy gardening!
starting giant pumpkins!!
Today I am planting giant pumpkin seeds. I will put them in 4″peat pots so that I can peel the pots away later without disturbing the roots when I transplant them. They grow really fast once they come up, so I will have to put them in the soil perhaps in 2 weeks from starting the seeds. I will transplant them once the first true leaf comes out. You can tell which way the vine will grow as it will grow in the opposite direction of the firs true leaf. This way I can place it in the soil in the direction I want it to grow. I am growing 4 giant pumpkins this year. They are: 817.9 Schieder 09, 1166 Mohr 09, 949.5 Harp 09, and the 895 Grande 08. They will go in my new pumpkin patch and I am growing another one: 352 Cabossel 09 (that’s me!) for the community pumpkin patch here in Santa Fe that I will plant when I teach a workshop May 15th. To understand what this means is the first number is the weight of the pumpkin the seed is coming from, the name is the grower’s name, and the last number is the year of the seed. So mine was a 352 lb pumpkin, my last name is Cabossel, and it was grown in 2009. That is how we giant pumpkin growers know what seed we are planting. We also look at the parents of the seeds we choose to see who they were as most of the time they come from very good “stock”. You can also just grow generic varieties that you can get from places like Amazon.com which is what I did when I started this hobby before I got serious. I grew a 225 lber from the generic variety which is fine for most people! I will try to break the state record here in NM this year. Have to beat 404 lbs…
Rocky Mountain Giant Vegetable Growers (RMGVG)
I am rejoining Rocky Mountain Giant Vegetable Growers (RMGVG) today. They are an organization that promotes growing giant veggies especially giant pumpkins and squash. If you join in the beginning of the year, they will send you a bunch of giant pumpkin seeds from their growers. They are located in Colorado. For those of us who want to try to grow giant pumpkins, they are the only group in the Southwest that have official weigh-offs at the end of the year that are part of the GPC (Great Pumpkin Commonwealth). The GPC is a worldwide organization for giant pumpkin growers. If you want to get in the official world record books you must go to a GPC sanctioned weigh-off.
