It is important to prepare the soil with green manure, compost and some minerals as well.

Crop rotation

Tomatoes can be rotated with legumes

One of the key points of organic farming. Tomatoes work well when grown with legumes. Legumes are known for their nitrogen-fixing properties. This will also help in avoiding pests.

Water requirements

Tomatoes are sensitive to water levels

This depends on the climate, soil type and plant size. Tomatoes usually need 1-1.2 inches of water every week. It is important to distribute water evenly.

Regular irrigation with 5-7 days gap in summers and 10-11 days in winter is ideal. Long durations of drought followed by heavy water supply will lead to cracking of fruit.
