2 . How to Grow Organic Tomatoes in a Container

Anyone who has seen tomatoes growing in a garden knows that they tend to be huge plants.     1     So the first thing to do when considering growing tomatoes in a pot is to find a suitable variety.

After you find the perfect plant, it is time to plant it. In general, plastic or fiberglass pots are best for growing tomatoes. They don’t dry out quickly. While tomatoes love heat, they don’t like being dry.     2     Besides, tomatoes need to grow in a reasonably large pot. A pot must be 8 inches deep. That’ s the absolute minimum. A 12- or 16-inch pot is even better.

Any good quality organic potting soil works for tomatoes. Don’t use soil dug directly from the garden.     3     Compost-based soil, whether purchased or mixed from your special recipe, is nice. When planting the tomato, put some soil in the bottom of the pot and set the plant in. After you have the plant set at the proper level, fill in around it with soil. The soil should go up to about an inch below the rim of the pot to allow room for watering.

    4     The best way to tell when to water is to stick your finger into the soil—if the first two inches are dry, it’s time to water.

The trickiest thing about growing tomatoes in a pot is that they are heavy feeders. Every time you water, you wash nutrients out of the soil. So fertilize （施肥） regularly. Once a month is good. But every other week, applying the fertilizer at half-strength is better.     5
