Tomatoes Not Setting Fruits - Knowledgebase Question

I have a really healthy tomato plant, and it has plenty of blooms. However, the flowers drop after blooming, and so far only 8 fruits have set. There are no natural pollinators around my plant at all--I read that that may be the cause. How can I get morefruits from the flowers (to stop the flowers from dropping)? One suggestion I got was to give the plant a gentle shake each day. Is that the way to go? Please help.

It's true that tomatoes need only a breath of wind to shake the blossoms and accomplish pollination, so go ahead and shake it up! Tomato pollen can be killed by hot weather, too. If temperatures are 90F or more during the day, and don't cool to below 75F at night, then I'd say this is the problem - and in Singapore, such weather isn't surprising. If the heat wave continues, your tomato may stop blooming until the heat breaks. Just treat it well, and it should rebound and offer a "cool-season" flush of fruit. In
the future, try heat-beating varieties, such as Burpee's "Heat Wave II'. Good luck!
