As the tomato season starts to wind down in the fall, I believe it’s time to redirect the plants’ energy so I trimmed off most of my blossoms on the tomato plants. This helps ripen the remaining tomatoes on the plant. I also cut off those crazy branches that are overgrown (and have blossoms) back to the last tomatoes that have been set on that branch. The idea here is to redirect the plant’s energy to stop making blossoms and put its energy into ripening as many tomatoes as possible before it freezes.
I also trim off any diseased branches where the leaves are dying or turning yellow and spray with Serenade again (probably for the last time). Late in the season, tomato plants are getting older and are more susceptible to diseases so my hope isn’t to cure any diseases but just keep it under control so we can still get many tomatoes. Besides we want all those green ones still on the vine that we have been patiently waiting for!
