Heat Setting Report-Beans, Tomatoes, Peppers
I thought some of you might be interested in hearing about what is and isn't suffering heat check among the warm season crops that sometimes have difficulty setting fruit in very high temperatures.
Bush Snap Beans: This morning I found several tiny green beans emerging from the dried blooms on my Festina bush snap beans. They were planted April 23 and have been blooming for two weeks with no pod set, until this morning. Yesterday the high was 111 and the low this morning was 78. Possibly, the plants are getting large enough now to provide a micro-climate suitable for pollination? Yesterday, I pretty much gave up on fresh green beans from this planting and accepted that they would make a good green manure crop for my fall cabbage, broccoli, etc.
Tomatoes: Continued low levels of fruit set on Capaya, Bella Rosa, Talladega, and Cherokee Purple. The first three are Tomato Spotted Wilt Virus resistant varieties; after three years of crop failure or significant damage from this problem, I have to rely on TSWV resistant varieties for a chance at a big crop from 12 plants. Capaya, a large roma type, has the heaviest fruit set. Also, as Dawn noted, timing of planting makes a big difference in fruit set. The 8 plants that I planted on April 20 (my frost-free date) have a far heavier fruit load than the 4 plants I planted on May 3 (the afternoon after my actual last freeze of the year).
Peppers: Gypsy continues to set fruit like crazy. The peppers are kind of small, but so are the plants and the peppers are very tasty.
The large bells aren't even thinking about setting fruit, although I did pick and toss one small Purple Beauty with a large sun scald lesion. The large bells are always a late summer/fall crop for me anyway.
Numex 6-4 is setting fruit, but the Poblanos aren't. Again the chiles are always a late summer/ fall crop too.
I set out the transplants on May 6 and kept the blooms pulled off the tiny plants until June 1.
By the way, the five day average temperatures here have been high 101 and low 71.
What beans, tomatoes, and peppers are setting fruit in your gardens in this extreme heat?
