Very few tomato blooms

Got plants almost 4 1/2 feet tall with no blooms. Any ideas

To hot. They drop blooms when it’s this hot.

Yep, what he said. This is why I always plant early and risk a frost. By the time you hit late June in Alabama most types of tomatoes will not set fruit in this type of heat. There are some hybrids out there that are supposed to still produce in the heat of summer but I have little experience with them.

Have you added too much nitrogen? If so, the plant uses it to produce foliage, not fruit.

Only put about a tablespoon of 13-13-13 in hole when i planted them.

Pinch off a leaf on about 50% of branches. It’ll queue them to put on some blooms.
