The plants look great, but no tomatoes! Google on Blossom Drop. http://www.ipm.iastate.edu/ipm/hortnews/1997/7-18-1997/tomdis.html Blossom Drop Plants fail to set fruit. Cause: Extremes in temperature and dry conditions may result in poor pollination and cause the flowers to drop from the plant without setting fruit. Blossom drop on tomatoes occurs when night temperatures are below 55°F or above 75°F. Control: Water the plants deeply once a week during dry weather. Fruit set should increase when temperatures moderate. Hormone sprays, such as "Blossom Set", may prevent some blossom drop due to low temperatures. However, the resulting fruit are often misshapen. Hormone sprays do not prevent blossom drop due to high temperatures. http://www.agway.com/lawn_and_garden/garden/tomatoes.shtml Blossom Drop Tomato plants often develop beautiful blossoms that mysteriously fall off. This problem is often temperature-related. Some varieties may drop their blossoms when night temperatures fall below 55° while high day temperatures above 90° and night temperatures above 75° may also cause blossom drop. To prevent it, plant resistant varieties, keep the soil evenly moist and avoid using high nitrogen fertilizers during the early stages of plant growth. Also watch for signs of early blight or bacterial spot that may cause blossom loss. It sounds like your daytime temps may be too high. As the second paragraph mentions, some varieties are more heat tolerant than others. The problem with buying big box store tomatoes is that they tend to stock "least common denominator" varieties, ie, varieties that will do well under average conditions. Around here, in South Carolina, it gets very, very hot in July and August, and most tomatoes stop producing. If I can keep the plants going until September, I usually see a second flush of tomatoes, With a late frost, I can get a decent second crop. Or, I *used* to see that. Since the War of the <spit!>Thrips began, I'm lucky to see tomatoes at all. I have, however, removed their reservoir, the place they gathered strength while waiting for me to set out my purty lettle tomato plants. I have removed all three of the mulberryless mulberry trees, and am diligently destroying all signs of sproutlets from the roots. Maybe, maybe this year, I'll have fall tomatoes. Anyway, I would suggest looking into varieties that were bred to produce in the heat. Penelope -- "Maybe you'd like to ask the Wizard for a heart." "ElissaAnn" <elissa@everybodycansing.com>
