How to Reduce Tomato Splitting:

1. Water: Water tomato plants once a week with about 1-2” of water. Keeping them regularly watered reduces the chance they will be shocked by a hard rain.

2. Mulch: Mulch does wonders for all plants, but especially for preventing cracking tomatoes. Add a layer of mulch 2-3” thick around plants to hold moisture.

3. Feed: Fertilize tomatoes with organic Tomato-toneevery other week during the growing season. Fertilizer keeps the soil healthy so plants produce as many tomatoes as possible.

4. Location: Growing tomatoes in raised beds or containers with drainage holes will lessen the problem because heavy rain will drain away faster in the loose soil.

5. Pick: As a last minute fix, you can always go out after a heavy rain and pick any almost ripe or ripe tomatoes.

While it may be too late now, you can plant varieties that are less likely to crack. Look for things like ‘crack-free’ in the description.
