DD has 12 heirloom tomato plants that she is growing in 5 gallon pails (2 plants to a pail). She planted them in early June from seedlings. None of them have any buds on them and they are getting "leggy" but not bushy. Some of the leaves are yellowing and falling off. The pails have good drainage, but it has been very hot and dry up here and the plants tend to be on the dry side. They have full sun for most of the day (at least 7 hours worth).
1) Are heirloom tomatoes usually late bloomers?
2) Does she need to feed them (Miracle Grow)?
Any suggestions or help would be most appreciated. Thanks in advance!
