Leave row covers on tomatoes for now

Many of you are asking when can you take your row covers off your tomato plants. Leave row covers on tomatoes for now-I know we are all anxious to take them off. I leave mine on till the monsoons come and they are NOT here yet. One of our local weather stations said that the monsoons might be delayed till July 25 and so I will leave mine on till the monsoons really come-this occasional rain we’ve been getting are not the monsoons and will not drive the leafhopper away. The leafhopper kills tomato plants by biting your plant giving it (CTV) Curly top virus which is fatal to your tomato plant but should leave when the monsoons come. The row covers are a physical barrier so the bug can’t get to your plant. So for now, (sigh) I will leave them on even though I’m dying to remove them like you.

I will post when I take mine off so you all know.

Snow/freezing temperatures on May 20th, 2019

Tomato plants waiting to be planted outside

Here it is May 21st and I’m now glad I waited to put my tomatoes in. I have wanted to get them in the ground since early May, but it was not to be. Last year was much warmer and I got my tomatoes in by May 6th. What a difference a year can make. Last night, it got down to 32°F and snowed. Not enough to stick on the ground but we are past the magic date of May 15th which is suppose to be the first frost FREE date here in zone 6b according to USDA. We’ve had a different spring here in Santa Fe with colder temperatures and lots more precipitation throughout winter and spring than last year.

So my babies are waiting to go into the ground in wall of waters till this Friday when it looks like this cold snap will be over. Wait. Wait. Wait. It will be in the 70s in the day and 40s at night for the next week and hopefully last nite will be the last of the freezing weather. And even though we will hopefully be past any more freezes, it still gets plenty cold for a tomato plant at night. They hate the cold. A good way to ensure they won’t get stressed or die if we get more cold weather again is by planting them in wall of waters. Here is a post on Wall of Waters 101. Meanwhile I wait—ahh crumba!

apricots this year? first time in 12 years!I hope my apricots will be ok. I’ve got a treeful of them right now and haven’t had an apricot harvest in 12 years! I will keep my fingers crossed that this freeze didn’t kill them. Ahh mother nature, whata ya going do?!

Tomato plants transplanted into pots

This past Friday, April 19, all the baby tomato seedlings were transplanted from the germination trays into 2.25 pots where they will stay until we plant them outside. There are 155 total tomato plants.

My main helper, Linda Archibald has been doing this with me for about 4 years and this year Tom Pollard joined us to learn how to do it all. It took us 4 hours to transplant them. Thank you folks! There were 4 tomato no shows which isn’t bad for how many we planted. It is amazing how fast the seedlings grow since it has only been 16 days since we planted seeds.

We use Moonshine potting soil from Agua Fria Nursery to grow them in-amazing stuff as everything grown in takes off really fast. So now they are off the heat mats and still inside under lights that will be 3 inches away from the tops of the tomatoes. I put the lights close so they grow sturdy stems. If you put the lights higher they can get too tall and lanky. As the plants grow, I raise up the lights with them. I will actually have around 28 tomato plants and Linda will have 59! The rest are orders. Looks like it’s going to be a big year for tomatoes for Linda! I hope she buys another freezer to store all that sauce she’s gonna be making! I’m hoping to get them out in early May again this year but Mother Nature will decide when they will go out, not me!

Tomato seeds starting to come up April 9th

The tomato seeds are starting to germinate in their trays. It has taken only 5 days!  Still more to germinate but many are already up. A few haven’t germinated so I will replant if they don’t come up in a few days. They are under fluorescent ‘daylight’  T-8 lamps that are in a standard 48″ fluorescent light fixture that I got from Home Depot. They are also on heat mats and I have a heat mat thermostat set to 80 degrees. The heat mats and thermostat I got at Amazon. I never use to use a thermostat but one year without it, the temperature went to 100 degrees and the seeds fried. With a thermostat, it controls the temperature perfectly to whatever is the optimum temperature for each crop. In this case, the optimum range for tomato seeds for germination is between 70-85 degrees.

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!

Dwarf Tomatoes started!

Dwarf tomatoes in foreground and on right side in background. The two taller ones in background are Lucky Cross tomatoes which are regular size indeterminate tomatoes

 

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. For earlier post on dwarf tomatoes, go here.

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.
