If it is hot a good watering 3 times a week - not so hot 2 times a week. Small plants need small waterings more often. The finger test is a good indicator also.

nick, I've read just to stick your finger in about 2 in. and if it's dry, then water. There's also fertilizing to consider. Homestead and Chill is a great website that has articles on Tomato's (deep watering/ shade cloth) and alot more. dan

I started my seeds back in January and transplanted them out mid-march like the diagram said. However, it does show you can plant them in April, but I would be careful because just as they are starting to take off the heat and humidity will be setting in. Depending on the variety most plants will not produce fruit when temperatures are consistently about 90 degrees. Which we are almost there in our zone. Adding shade over them can help! Otherwise, I use the tapping method to aid with pollination :).

Do you see any pollinators? Try using a tiny paint brush to mix pollen on each flower.

Just lightly tap the flowers in order to pollinate them and they will form tomatoes.

Try watering with a mixture of epsom salt (1 Tbsp per gal of water). Also, if you,ve seen the banana peel water combination I swear by these two methods. I have the biggest plants and the tomatoes are just loaded on every single plant. It works great for peppers too!

Maybe you don't have enough pollenators. Have flowers around. Make sure you're not spraying something that kills or repels pollinators.

Try a bit of pot ash or potassium.

I belong to a community garden locally, and we seem to disagree on how to raise tomatoes! The tomatoes have mostly not done at all well. They are in raised beds but are watered thoroughly every night. Some of us feel they've failed because of too much water. They are watered low down but drenched! Most of the tomatoes are not formed properly, or never formed at all, they are mishapen, and motley. in other words barely usable. The leaves have browned and shrivelled. They just haven't looked healthy. They haven't been mulched because of the slater problem but have mostly mushroom compost dug in. Can you resolve this issue for us please?
