They are blossoming, every plant has a blossom on it, then it slowly turns into an okra, after I cut that one off, the next day it shoots off a new blossom and it starts again. If I miss a day watering, they don't produce. I run the water via both a soaker hose and a series of low ground level sprinklers for about an hour every day unless it rains, and a bit less on cloudy days figuring there's less evaporation loss.
The nights here are now starting to drop into the high 40's to low 50's consistently, with days in the mid 70's. The leaves are getting narrower and the new growth looks weaker or slower.
They're loosing the lower leaves faster now. Before the lower leaves would hang in there for about a week after the last okra was picked from that plant.
What they are doing is that they are growing only vertical, after picking an okra, the plant sprouts three new leaves, puts on one blossom, and an okra forms, when picked, it repeats and the last leaves die out soon after and it keeps going. I get to fill a bag every 4 or 5 days now, but I really figure that the plants will give up soon due to the temperatures at night.
What puzzles me is that I've been saving my seeds every year since 2009, plus planting a complete row of new seed that I buy along side. Both rows are doing the very same thing.
In all prior years, my okra grew more like a hedge row remaining full from late June to the end of September or so. I usually just let it go for seed at this point allowing at least half the largest plants to fully mature and eventually dry out their okra pods to give me seeds. Once the pods turn brown and dry up, I clip them, hang them to dry and usually by mid winter I cut them for their seeds. When the weather is staying over 60 degrees at night in the spring, I till, fertilize, and plant again.
I've done the same thing every year here since 2004, and did the same as a kid at my dad's house in the 60's and 70's.
I started saving my own seeds after having a year where not many of the bought seeds came up or amounted to anything. After getting some seeds from a new source the following year I started to save seeds, at first I wasn't sure what I was going to get, not knowing if the seeds were a hybrid or not but the result has generally been better than before. Each year I buy a handful of seeds for the second row, plus I plant the raised bed up front as sort of a control. That raised bed gets 100% new, fresh soil every year, always different from the soil in the main garden but with the same prep and initial fertilizer. Its also where I test anything new, whether it be pest control or fertilizer.
There's a local farm co-op here run by a college that will do soil testing for free and advise you on what to add if needed. The last soil test, from June, said all was fine, and to continue 10-10-10 on my tomatoes monthly.
I added some 12-12-12 to the okra once they first set blossoms, I simply ran a pointed hoe down the middle of each row and poured in a trail of granulated fertilizer as I always do. For the tomatoes, I have 1.5" PVC tubes stuck a foot into the ground by each plant, each tube has several holes on the bottom sides and an open end, I put a handful of 10-10-10 down each tube ever month and fill the tube with water. I also have 5-10-10 and 5-10-5 but I found that anything less than the 10-10-10 limts the leaf growth too much.
