Q.In New Orleans we Plant Tomatoes (lots Of Different Types) And Often Get Lots Of Buds But Few Tomatoes.
Summer planting gets almost none. Seems like we get lot of stems and leaves with few buds, and then after the plant gets 3 or so feet high it gets some buds but lower branches very seldom get any. Buy at local Home Depo so variety should be ok for local conditions.

Tomatoes will not set fruit when temperatures soar beyond 90 degrees F (32 C) during the day with nights over 76 degrees F (24 C). Could this be the problem with your summer tomatoes? You might do best with fall tomatoes temperature wise.
