Greens in the Green House!

So my greens made it through the worst of winter (I hope) and have really started to kick in growing. They went on hold (stopped growing) from around Thanksgiving to mid-January when we had less than 10 hours of daylight. But since then the daylight hours keep increasing daily which is a signal for the plants to grow again in earnest. In case you are wondering when I planted all this, I planted the carrots, arugula and spinach last September inside the greenhouse, and the red and green lettuces I started from seed under grow lights inside my house on January 2nd and then were put out in the greenhouse in early February.

To keep the greens from freezing in the dead of winter in the greenhouse which is unheated, I’ve cover them with one layer of winter weight row cover every night and on some really cold nights (when temperatures got down to 14-17° F), I put two rows of row cover over them. One night the lettuce actually froze. But I read in Elliot Coleman’s Winter Harvest Handbook that if you don’t harvest it when it’s frozen, it may be fine by the afternoon when it warms up and sure enuf, it thawed out and is still growing great. You just can’t harvest it when it’s in a frozen state.

My Greenhouse a few summers ago

In the greenhouse are some carrots which aren’t very big yet (about the size of a pencil in circumference) some green and red lettuces, arugula and spinach, all of which will be harvested before the Green House (a play on the word greenhouse since my greenhouse was painted green) gets too hot. In fact when the day temperatures reach the 50’s, I put fans on to blow the heat out of the greenhouse.

 

Pray for heat, girls!

You see, I don’t worry about it being too cold but worry about it getting too HOT which will cause the lettuces and spinach to bolt (make flowers) which will cause it all to go bitter and then it is only good for our chickens who don’t seem to mind the bitterness at all. In fact I think they pray for the heat!

Looks like some of the lettuce and spinach are now big enough to pick the outer leaves while leaving the inner leaves to continue to grow. And a big bonus for me is to see so much green now already at the start of March! I love going into the greenhouse right now. Refreshing when the outdoor plants are still sleeping…

Cool season crops have begun

transplants-2-weeks-old

When I was looking through what I plant each year, I realized I actually grow many varieties of cools season crops (like greens/lettuce). I started some seeds of cool season crops inside under lights but no heat on Jan 17!  I never put the heat mats on for cool season crop seeds, only for warm season crops and it is way too early for them just yet.

I started:
Asian greens: bok choy, pak choy, Wasabi arugula

Lettuces: 4 Season Lettuce butterhead, Yugoslavian Red butterhead, and Santoro butterhead lettuce. Can you tell I like butterheads?!

Leeks: Solaise, King Richard and American Flag

Onions: Candy (it is an intermediate or neutral variety) which is they type of onion we have to grow here.

Spinach: Carmel-Just planted the seeds today. Still have some spinach plants that have overwinter nicely outside in a raised bed with only winter weight row cover on it. By planting a crop of spinach last fall, I’m hoping I get a bumper crop of spinach in March! The variety of spinach I like the most is called Carmel which overwinter last year and looks to do the same this year. You can get seeds from Johnny’s or plants from Agua Fria Nursery.

4-season-lettuce

four season lettuce is looking good

Today I transplanted up lettuces and Asian greens to pony pots from seed trays. The plants are looking good but need to grow more before I put them out in my green house or cold frame. You can plant outside in sunny raised beds in March but all-greenhouse, cold frames or just plain old beds will need winter weight row cover on the little starts to protect them from our cold nights.  I’m hoping to put them out by beginning of March. The varieties I grow at this time of year are very cold hardy. I’m trying to get a head start as our cool season crop season is pretty short here before it gets too hot and everything bolts. And there is nothing better than spring spinach or lettuce!

Extending the Season-Making a Low Tunnel

low-tunnel-2016

These broccoli transplants were put in on Aug 24, 2106

I taught a class in late August on Planting for a Fall Harvest where I showed the students you don’t have to have a Greenhouse to extend the season. You can also have a cold frame or even simpler is what I call a low tunnel. Now with the cold nights, you definitely need something over your new fall transplants.

low-tunnel-before-row-cover

Here is the frame of the low tunnel before row cover-just fencing material curled into a u-shape ready for plants underneath it

I like to make my low tunnels out of 2″ x 4″ fencing or even concrete reinforcement wire.  I just open up the fence roll, cut off enough so it will be curved above my plants and turn it upside down on the soil.

img_3998_1024

row cover over the low tunnel protects crops at night

Cover it with winter weight row cover (1.0 ml).  I put rocks on mine to keep it from blowing away. Now you have a secure low tunnel that will protect your plants during the shoulder season that is closing in on us quickly. What is a shoulder season? It is the time of year when the temperatures can drop quickly at night near freezing and then heat up in the day. The temperature shifts can swing wildly during the shoulder season. We have a shoulder season in spring and fall. By making a low tunnel, you can extend the season and grow vegetables like spinach, arugula, kale, lettuce, bok choy, mustard, mesclun, radicchio and other cool season crops much later. Fall is a great time to plant cool season crops and it’s not too late if you get transplants now. It might be too late if you start from seed unless it’s lettuce. Try to pick varieties that are cold tolerant.

Starting COLD HARDY VEGETABLES Super Early

lettuce_greenhouse germinating

So now that the Persephone period is almost over and the magic date of January 15th is upon us, what does that mean? It means our day lengths are getting longer and January 15th is when we start getting 10 hours of daylight that will continue to get longer every day. Have you noticed already it now gets dark around 5:30 instead of 5 pm? The darkest time of the year is over. What does that mean to gardeners? To learn how to start cold hardy vegetable seeds super early outside and how also how to start them inside read on.

STARTING COLD HARDY VEGETABLE SEEDS OUTSIDE: cold frme opened
If you want to try growing cold hardy vegetables outdoors at this time of year, you will need a cold frame, low tunnel or hoop house.

If you already planted cold hardy vegetables late last fall in a cold frame, low tunnel or hoop house, you may have noticed that the little seedlings haven’t been growing much at all as winter set in. Now with longer daylight hours, they will start to grow again and barring any devastating freezes, they will continue to grow and you can get cold hardy crops earlier this spring.

In late winter, before you have harvest your winter crops, decide what you want to plant in your bed once space opens up in your cold frame.  As the end of the Persephone period draws near (January 15) , you can re-seed the openings created from your harvesting or you could start planting seeds in your bed if you don’t have anything growing. My soil in my unheated greenhouse is at 40°F right now (as of January 12). Lots of cold hardy vegetables germinate in cold soil.  They will be slow to start at first but they will start as your soil warms up to 40°F and warmer. Now with the day light getting longer, you can think about starting early. The winter sowing you do will be ready for harvest by early spring, often long before the same crop when grown outside without protection. A bonus is many of the cold hardy winter crops don’t like our springs, bolting on the first few warm days so you’ll be able to harvest that spinach before it bolts!

Some cold-hardy plants planted inside a cold frame, low tunnel or hoop house can tolerate a hard freeze at night, provided they are allowed to thaw during the day. The plants must be completely thawed before you harvest them. In addition, put some winter row cover over seedlings at night to give them an additional 4-6°F protection even though they are already in a cold frame, etc. Remove the row cover on days when it is above freezing. Watering is necessary to get crops started, but they will generally need very little water during the winter season-early spring once established.

Cold Damage on Winter Crops

garden dec 9 2014

Well  here it is in early December and not surprisingly, most of the outside crops in the main garden, ‘bit the dust’ as they say—died. A few are still alive. It is warmer now—here are the results of those cold snaps we had.

 

The Toscano Kale with freeze burn. It is more sensitive to cold temperatures  than other kales

Toscano Kale

The Toscana (aka Lacinato or dinosaur) kale got severely damaged. It is cold sensitive and although it’s not completely dead, it is unharvestable. Here it is with the leaves burned from the cold.

 

Russian Red kale is still alive

Russian Red kale

 

The Russian Red and Curly Leaf kale are still going and have some damage as well but the new growth is doing well. I haven’t watered them at all-nature has with a little snow and a nice rain the other day- almost an inch. I do have them covered with 2 layers of winter weight row cover.

gourds in field

The gourds are still drying in the field. Some are starting to get lighter in weight so I will put those in the garden shed to finish drying. The rest will stay outside until they dry more.

bubble wrap down on windowsThe green house is button up fairly tight now with just a little venting at the top panels. I’ve put the bubble wrap on all the windows (bubbles faced to the window) for extra insulation. I’ve also put the 4 barrels with water in them on the north wall for them to absorb heat in the daytime (I took them out during the summer), releasing the heat at night (the theory is that the sun which is lower and further to the south will hit them on the north wall and warm up in the daytime). I’m not sure I have enough barrels to do much good but even one degree will be helpful once it gets cold again.

winter lettuces

I’ve planted 2 winter lettuce varieties in the green house as transplants back in early November. The cold hard varieties are a green variety-Winter Wunder and a red variety-Marshall Red Romaine. They both have made it so far through those cold snaps although they have slowed down in growth because of the shorter daylight hours. They will stop growing until sometime in January when the daylight hours start to get longer.  Winter Wunder is my favorite lettuce but only grows well during the cold months. When it starts to get even a little warm, it will bolt. The lettuces have 2 layers of row cover over them at night and have some protection from the unheated greenhouse (at least from the winds). I’ve also noticed that the lettuces don’t need a lot of water now (about once every 2 weeks). It will be interesting to see if they make it Dec-February. Don’t they look wonderful in the winter!

There has been about a 4-7°F difference between the greenhouse temperature and the outside temperature at 7 am in the morning when I check everything. When I add the row cover at night I get about 4-6 degrees more protection. I’m not sure what to expect this winter since this is my first December-January  in the greenhouse. Last year when we finished up the greenhouse I start planting on February 17th so now I will see if these established greens can survive Dec-Jan.

Winter greens for the greenhouse or early planting outside

I can’t wait anymore! I got this newly completed greenhouse and am antsy to try it out. I’ve done a lot of research on which plants might do well in the winter and am ready to rock n’ roll! So I am planting cold hardy seeds this week inside the house. I will transplant them into my new greenhouse when they are bigger. I’m also going to try some direct seeding in the greenhouse in the raised beds like arugula, spinach, kale, baby bok choi and mache in mid-February-all of which can handle some pretty cold weather. How cold? We will see soon although you wouldn’t know it by this week. I will also plant other greens like some winter hardy lettuces, peas, and a winter hardy variety of chard called Argentata at the end of February-beginning of March. Everything planted in the greenhouse will have to have row cover over it even in the greenhouse at this early date because of our cold nights. For those of you who do not have a hoophouse, or cold frame, the seeds in the list below will do well outside only you have to wait a little longer.

Here is my list of cold hardy crops to try in the greenhouse. You can also plant these outside in March once the soil is not frozen and cover them with row cover:

Fall Vegetable Planting Schedule

Fall harvest. We only wish our gardens were this GREEN! Photo courtesy of http://gardening.ktsa.com

Ok, so now since it is time to plant my fall veggie garden, here is my planting schedule

FIRST-WHAT TO PLANT AND WHEN

Depends a lot on what you like to eat. Below is MY list of what I want to plant for a fall garden. Some of these are already growing in the summer garden and will be ready to harvest soon like the carrots and beets so I must decide if I want more in the fall.  All of these planting dates are estimates depending on the variety you grow and are based on planting outside, not in a greenhouse. Look on your package of seeds or on the plant label for seedlings for accurate harvest times and go backwards from Oct 3 for Santa F+ add 14 days.

JUNE

Fennel (Finnochio-bulb type)-Sow seeds mid June. OPPS! Missed this. The short cool days of fall are even better for fennel than spring. You can still plant this (IN JULY) as it likes cool nights although the bulbs may be smaller since we missed it’s prime planting date.

JULY-AUGUST


Asian Greens/Bok Choi- Sow seeds mid July. Can handle light frosts. Harvest days depends on variety. Look on seed package.

Beets- Sow seeds in mid July-early August. Can handle freezes but must mulch with thick straw or row cover. 45-65 days to harvest.

Broccoli- Sow seeds early July-mid July. Can handle light frosts. 55 days to harvest.

Broccoli raab- Sow seeds in early July-mid July. Can handle light frosts. 45 days to harvest.

Carrots- Sow seeds in early July-mid August. Can handle freezes but must mulch with thick straw or row cover. 70-80 days to harvest.

Chard- Sow seeds late July-. Can handle some light frosts. Cover with row cover when it gets cold to extend season. 50-60 days to harvest

.

Kale- Sow seeds early July. The short cool days of fall are even better for kale than spring. Kale that is established will last well into winter and can survive below freezing temperatures down into the 20s.

Lettuces- Lettuce baby- Sow seeds in early-August. Seedlings will need consistent moisture and shade from the afternoon sun on hot days. Cover when it gets cold to extend season but it will not survive freezing temps. 45 days to harvest depending on type and variety.



Peas- Sow seeds in early-July-mid-July. Likes cool but not freezing weather. 60-75 days

.

Radish- Sow seeds late July. 30 days to harvest.

AUGUST


Spinach- Sow seeds early-August. The short cool days of fall are even better for spinach than spring. Spinach that is established will last well into winter and can survive below freezing temperatures down into the 20s although it will stop growing. Why doesn’t it freeze? It produces an alcohol inside-alcohol won’t freeze! 45 days to maturity.

Endive, Escarole-Sow seeds early August. The short cool days of fall are even better for these than spring.



Lettuces- Lettuce head – Sow seeds in anytime August. Seedlings will need consistent moisture and shade from the afternoon sun on hot days. Cover when it gets cold to extend season but it will not survive freezing temps. 45 to 60 days to harvest depending on type and variety.



Mesclun mixes- Sow seeds in early-August. Seedlings will need consistent moisture and shade from the afternoon sun on hot days. Cover when it gets cold to extend season but it will not survive freezing temps. 45 to 60 days to harvest depending on type and variety.



Arugula- Sow seeds in mid-August-late August. Fast growing. Can handle some light frosts. 
30-40 days to harvest.



Kale- Sow more seeds mid August. The short cool days of fall are even better for kale than spring. Kale that is established will last well into winter and can survive below freezing temperatures down into the 20s

OCTOBER


Garlic-Sow largest cloves anytime in October after the first frost. Harvest in late-June-July

Shallots-Sow largest bulbs anytime in October after the first frost. Harvest in late-June-July.

I’m 

not a big fan of kale, endive, escarole and collards, but went ahead and listed them as I know many of you like them. Cabbage and cauliflower take too long to grow for me. Forgetaboutit!

SECOND-WHERE TO PLANT


Do you have garden space close to your house for easy watering and harvesting as it gets colder? This is important to consider if your main garden is far away from your home. I have two places to plant them now. My cold frame and my raised beds up by the house. If I ever get my greenhouse done, I’ll have another great place for veggies but for now I’ll plant in my two spaces.

Cold frame in previous year

My first space is my cold frame up by the house. Since it is too hot now, I think I will have to put some shade cloth over it to keep plants cooler inside. Also I want to get one of those automatic vent openers that will open the lid if the temps get too hot and close it when it gets too cold.

The shallots will soon be done in this raised bed and I will use it for fall planting

My second space is the raised beds also up by the house. Raised beds are great as they keep the soil warmer in the fall when it is getting cooler. Since I already pulled all the garlic in these raised beds, I will plant a few cold hardy vegetables in them and then plant garlic and shallots between them come October. The beauty of having some garden space close to the house is when it does get cold, I won’t have to walk down to the main garden to water and harvest. I can just get a watering can and go right outside the house. Also I can replace the light row cover that I keep my cool season crops under (keeps the critters and bugs away) with a heavy row cover on the beds if a sudden frost comes up. The cool season crops will be picked by the time winter hits and the garlic and shallots will sleep till spring!
