Hang in there!

My tomato plants are covered with row cover now but soon they will come off.

Hang in there! According to the weather apps, we are almost into the monsoon season here in Santa Fe. Historically it starts around the second week of July-let’s hope so. I for one am looking forward to it-we need the rain plus I would like to see my plants.

So be patient if you have your tomato plants covered with row cover. Some of you may be tempted to take them off early but we’ve waited this long and we are almost there.

The row cover is providing protection for your plants by acting as a physical barrier between your plants and the beet leafhopper that carries a deadly virus called Curly Top Virus (CTV) if it bites your tomato plants. Some of you haven’t done this and you may be lucky or not. You will know in about 3 weeks. But the good news is the bug either leaves or gets suppressed when the monsoons come in earnest and only then do I take off the row cover. I wait till it’s gone. Growing tomatoes should not be this hard, but it is here in the southwest. The northeast coast has their Late Blight (which is worse) and we have CTV.

I’ll post when I take the row cover off the plants and we can actually enjoy watching them grow and produce tomatoes!

Root Trainers-unique propagating trays

Fava beans in Root Trainer

I started using ‘Deep Root trainers’ last year for my fava beans and other bean crops that need deep cells or for plants that don’t want the roots disturbed when planting. The cool thing about them is that the cells are 5 inches deep and shaped like a clamshell, with two sides that open up like a book.  There are 8 sections total that fit snugly in a tray to hold them upright that comes with the kit. They are great as they have grooves that keep the roots growing straight instead of circling in the cell and strangling the plant. They also air prune when they hit the bottom of the cell.  No need to transplant into another pot, just plant them out in the garden. You just put seed starting soil in each cell, pat it down and put the seeds in. The only drawback is the plastic clamshells are very fragile and must be handled super carefully to keep from cracking but knowing that, I am careful and have them for three years so far. You can get them through Amazon. Get the 5″ deep ones, NOT the 3″ ones.

Pictured above are fava beans in their cells, 6 are already planted in the ground. Just carefully open the clamshell and slide them out into your hole in the ground with no root disturbance for those sensitive plants that hate to be transplanted.

Craupadine beets started in Root Trainer

I also used root trainers with a hard to germinate french variety of beet called ‘Craupadine’. It is probably the oldest beet in existence. I have not had much luck with germination when planting these seeds directly in the ground so I decided to try them in the rootrrainers this year and have much better germination although still spotty. I thought being a root vegetable, they probably would not like to have that main root disturbed. I think they will do well. I won’t wait till the plants are too big.  I am planting them outside after the first true leaves (cotyledon leaves) come out. So far 27 have germinated which is more than I have ever grown at one time.  They are ready for transplant above. I am so excited as these are the sweetest beets I’ve ever eaten. The french farmer markets cook them over a smokey fire in foil and serve them still warm.

Dwarf Tomatoes started!

Since I’m involved in growing dwarf tomatoes for Craig Lehouiller in his project, I decided to grow some of his varieties of open pollinated dwarf tomatoes that have been released to the public. I got the seeds from Victory Seeds. I’ve never grown dwarf tomatoes before. All the dwarf tomatoes will get between 3-4 feet tall and are stockier than regular tomato plants. They are indeterminate variety so the they will grow like all other indeterminate tomatoes only slower throughout the season and will be shorter. Indeterminate tomatoes keep producing fruit till it freezes. The actual tomatoes on dwarf tomatoes aren’t necessarily smaller just because the plants are. The days to harvest can go from 65-80 days depending on the dwarf variety. I am trying 10 released dwarfs plus 6 more unreleased in trials for Craig. So I am heavily invested in the dwarfs this year but I am growing some of my all-time favorites as well.

I noticed right away that the dwarf tomatoes pictured above are shorter and stockier even just after germination. I start all my tomatoes in shallow seed propagation trays on heat mats with a thermostat and under lights inside the house. Because of their shallowness, the soil heats up faster so germination is faster but you must water them 2x a day.  The two taller tomato plants in the background on the left side are regular indeterminate tomatoes called Lucky Cross, which is one of my favorites but notice the height difference with the dwarfs being much shorter and stockier.

Cold nights are here-protect you plants!

Atomic Red and Cosmic Purple carrots harvested last week

 

Here it is Friday, November 17 2017 and I was just remarking that except for the one cold night that killed off all the tomatoes in September, how warm it has been. If it wasn’t for that one freezing night, we’d still be harvesting tomatoes!

Well it changes tonight getting well below freezing and will continue to be cold with temperatures in the mid-20’s at night and low 50’s in the days for about the next 5-6 days.

All the warm season veggies have been done for a month but I still have a few cool season crops out in the garden like Lacinato kale, Voiletta bok choy, Florence bulb fennel, Atomic Red and Cosmic Purple carrots, Detroit Red beets and Argentata chard. Since I want to keep them going as long as possible, I will put winter weight row cover (.9-1.0+ mil weight) over the plants to protect them until the temperatures get above freezing at nights. Also I have lettuces and spinaches growing in the unheated greenhouse and will cover them as well. Of course an option is finish harvesting everything and call it a season!

Early Blight on Tomato Plants

This tomato plant has severe Early Blight as it has worked its way up the plant

Now that the monsoons are in full blast, tomato fungal diseases are showing up with all the moisture. One of them is Early Blight. It is caused by a fungus called Alternaria solani. Early Blight is a fungal disease that attacks tomato plants starting on the bottom leaves of the plant and works it’s way upwards. The leaves start turning yellow and get blotchy. If left unchecked, it can take over your plant killing it although it won’t die immediately. Where does it come from? It comes from water splashing soil up on the lower leaves, allowing the fungal spores to colonize on the leaves. The culprit is a bad soil fungus (there are good soil fungus as well). That’s why you always see it start on the bottom leaves. Early Blight should not be confused with Late Blight which is prevalent in northeastern United States. We don’t have Late Blight out here in the southwest (at least not yet).

Here is a close up of Early Blight on the leaves

-There are several things you can immediately do to help with this disease if you get this. The first thing you do is trim off the affected branches where the leaves are yellow. Keep trimming up your plant as needed and spray with an organic fungicide like Serenade.

-Disinfect your shears between plants by dipping the shears and your hand in a container of water with about 10% bleach solution. Alcohol also works. Be sure to disinfect your shears between plants because you can spread Early Blight.

-I like Serenade, an organic fungicide which provides protection from a broad spectrum of common fungal and bacterial diseases. It is a biological fungicide, meaning it uses other spores that crowd out the Early Blight spores. Spray it on when the leaves are dry. It is rainproof, non-toxic for bees and other beneficial insects. Respray every 5-7 days. Spray all parts of the plant-both on top and underneath till dripping. Serenade is also good to spray on other vegetables. Spray for powdery mildew on squash, cucumbers and melons and leaf rust on beans. I use it for all my vegetables. Don’t wait till you get the disease—it works best as a preventative but you can control many fungal diseases with Serenade.

-In addition to trimming the affected leaves, trim off any branches or leaves that touch the ground. I never let any leaves or branches touch the ground, trimming them up about 12 or more inches.

-Another option is to stake or tie up any branches that might touch the ground.

Mulch with straw underneath the plant so the soil can’t splash up on plant when it rains or if you water overhead. This is key to help prevent Early Blight on your tomatoes. I do it the minute I plant my tomato plants in the spring and add more straw as the plant spreads till eventually the whole bed is covered with straw. If you didn’t do it this year, you can still add straw now. Besides it’s also great for keeping moisture from evaporating in our hot sun.

-If space allows, rotate susceptible crops every 3 years. Just change where you plant tomatoes every year.

Why are my tomato plants dropping their blossoms?

When the temperature outside is 92°F or hotter, the tomatoes will drop their flowers (blossoms) and will not set any fruit. This is called Tomato Blossom Drop and is normal for a tomato to do. Basically they self-abort their blossoms. Why? Because they want to survive. They will continue to produce new blossoms and once the temperatures is BELOW 92°F, they will start to set fruit from the blossoms.

What can we do to prevent blossom drop? Nothing. We really are at the hands of mother nature. The funny thing is once they do pollinate (tomatoes are self-pollinating and wind-pollinated and don’t need pollinators) and they produce baby fruit, they do fine when it’s hot-it’s just while they are trying to set fruit that the temperature is critical. There is also a low temperature where they will drop the blossoms, but we don’t have to worry about that here.

Last year we had 3 months of intense heat with everyday being 92°F or warmer and the blossom just couldn’t set fruit. Finally when the monsoons came mid-August (which is one month later than normal), and it cooled down, they were able to set their fruit. Luckily for us we had a long fall and were able to harvest before we got a freeze. So don’t despair, they will set fruit from their blossoms when the time is right. Hopefully the monsoons will come in July. So for now, just surrender and chill out (if you can).

Row cover protects tomato plants and more

Here is what my garden looks like right now. Just about everything is covered with a material called row cover (also called Remay). My tomato cages are covered from top to bottom with it. This acts as a physical barrier to keep a bug called the beet leafhopper from biting them and transferring a disease called Curly Top Virus (CTV). I’ll take it off my tomatoes when the monsoons arrive.  The bug leaves when the monsoons come.

I also put row cover over my other veggie transplants while they adjust to the heat and wind when I transplant them into the garden. And I put it over other veggies that I plant by seeds like beans, cucumber and corn. I just plant the seeds in the ground and put a sheet of row cover over them tacking it down with rocks so the wind doesn’t blow it away-but don’t make it too tight.  Give the plants some room to grow under it. When the seeds germinate, row cover keeps the birds from eating the sprouts and I don’t have to replant seeds as often. Plus you can water right through it. Row cover comes in 3 weights. A heavy weight (1.0) for fall-winter, a mid-weight for summer (.5) and a light weight (.3) which does not work well here because of the winds-it rips easily. I use a mid-weight in the summer in my garden.

So basically I use row cover in the beginning of the growing season on almost everything. You can get it at most nurseries.  And you won’t have to keep it on all summer. Once your corn and beans grow up about 4 inches, and your transplants adjust to outdoor growing and the bugs leave, you can take it off and enjoy watching your garden grow. Another plus is it gives some protection against hail. Great stuff. I highly recommend it to be a more successful gardener.
