I always plant at certain times because that's when, for what ever reason I think I
should plant. The last couple of years I have been very happy with my garden ( of
course there's always something that doesn't work, but for the most part I'm happy).
This year I took into consideration what temperature plants like. For example tomatoes don't like temps lower than 50 and peppers 60.
This year our spring was strange. I would get ready to plant the tomatoes I started in the house, and were living in the unheated
greenhouse. The forecast would be a low of 50 for 4, or 5 nights then dip to low 40s. I knew it wouldn't kill the tomatoes, because normally they would have already been planted. This up and down temp pattern lasted a lot longer than usual. Finally in mind to late May the 10 day forecast stayed above 50. I planted the tomatoes, then a little later peppers. I figured production would be pretty late this year. That has not been the case. It's been the opposite. We have already eaten lots of cherry tomatoes, peppers, cucumber, egg plant, zucchini, and squash. We should have gotten 2 regular tomatoes, but the birds beat us to them. This is a lot more veggies a lot sooner than I ever remember. Some of it may be the weather, I have heard lots of people saying there garden is doing very well this year. But I really believe planting according to the nighttime temperature is the key. I believe there's a lot less transplant shock, and they hit the ground running. I won't know for sure for a couple of years, but we are sure enjoying the results this year.
