Tomato Blossoms Dry Up

My container tomato plant has several blooms, however, each bloom is immediately drying up. Anyone have any suggestions on what to do???

Tomato season is winding down in many parts of Texas (esp. central and south) - a little earlier than usual this year because of the heatwave and drought.

Blossom drop can be caused by a number of things, but in your case, it is most likely due to the unrelenting heat we've been experiencing both day/night. What can happen is that extended duration of heat kills (denatures) the pollen, so the blooms do not pollinate. Then they dry up and fall off.

Night temps matter even more than day temps, and because it has now been hot for so long w/o any let up, we aren't getting coolish nights any more.

If the plant still looks fairly healthy, move it to a more shady spot, and shake it every day. The shaking can sometimes help a little with pollination. However, it won't work miracles if the pollen is already denatured.

A good siting might be to move it where it gets good morning sun, but some shade the rest of the day. Like maybe on the east side of a tree or tall structure. Good luck.

Btw, now would be a good time to take some cuttings from your plant and root them for a fall crop.

Sanroc, i dont know the varities of toms you planted, but in tx. you need to get toms that set fruit well in heat, like homestead, manalucie,costoluto genovese,c-tex, porter etc.these all set fruit well in zone 8. hope this helps.
