Here we go on the annual list of things that I need to do differently next year. I hope you slept well last night because this is going to be boring.
Every year I make this list, and then I mostly abandon it as things get busy. I forget the same battles I fought last year. So, in order to further anchor my life in tradition, here is the list:
1. Prune more, including at least one of every three secondaries. Perhaps more. Every year my plants grow more thickly than I want. This prevents light from getting through the canopy and warming the soil. Also, some pruning of the secondaries may help in getting a longer main. My best, the 779, was grown on a 13 foot main which is more than my usual 10 (or less) foot main. I'd like to see what I can do with 15 to 18 feet on the main!
2. Watch that stem!! Every year I mention this. And every year I have problems. I've got to figure out a way to manage the vine and the stem. Another thing, a longer main is going to help with this. A good section of the main vine cannot "root" into the ground when it must be raised to go with the stem.
3. Leaf health. Wow, I really do have terrible leaves by the end of the year. I figure that the "lifetime" of one of my leaves is about 90 days. That means that the first leaves are dying by mid-year. By September, only the newest leaves are healthy. This is going to take some research. I don't know if Daconil, or something like Agro-K is going to help.
Those are the easy things. The heart of the matter is.......... drumroll please.........
4. Heat. I've been pondering ways to get more heat into my soil. Of course the key number one thing to add heat is to use a hoophouse, something that I've finally become proficient at. But I'm considering a change in my approach. What I want most is heat in the root zone. Hoophouses, give lots of heat in the above ground, where the plant is. They can turn a 60 degree day into a 90 degree day, and a 70 degree day into 110 degrees. This also warms the soil, of course, but...
My studying on this subject suggests that a clear plastic sheet laid directly on a raised bed is going to provide significant soil temperature warm up. In conjunction with this, I will bury a soaker hose to provide moisture. I'm thinking of a 3-foot radius (6-foot diameter) piece of clear plastic around each plant. And then, just leave it there all year long!
So with this in place, would I still do a hoophouse or cloche? I don't know. Here's what I'd like to do: Use something like a "wall-o-water" (for tomatoes), but larger, and made of hard plastic so that it has no chance of collapsing on the plant. (We spend too much effort on this to have it ruined by a collapsing wall-o-water!) I've seen these. They're like an igloo that can be filled with water. But if I could find such a thing that is about three or four feet in diameter, that would be perfect.
