Growing Food in Pots Can Be Easier Than Planting
Two of the hottest trends in gardening are containers and cultivating fresh food, and many savvy families are beginning to combine the two. They’re growing their vegetables in pots.
Improvements in potting soils and fertilizers have made this a straightforward and generally successful exercise, said Pamela Crawford, a landscape architect from Canton, Ga., who has written four books about container gardening.
"It’s so easy to put a tomato into a pot. It almost grows itself," Crawford said. "It’s a whole different ballgame than putting one in the ground. There’s less weeding involved and fewer insects to fight. Container gardens are more productive and involve less work."
Shapely pots and colorful plants are a great combination for growing edibles - especially where garden space is lacking. Containers can deliver the goods and in remarkably large quantities.
"I’ve been able to harvest as many as 236 small spicy peppers all at once from four plants in a 16- to 20-inch container," Crawford said, referring to habaneros. "I’ve also been able to get my fill of tomatoes from a pot that included a few ornamental sweet potato vines with their large root systems. It’s amazing how little ground space plants need to be productive. They can tolerate being crowded."
Mixing flowers with ornamental vegetables makes good container sense. Cucumbers, coleus and begonias are eye-catching when planted together. Other great potted pairings include rosemary surrounded by lettuce, viola tucked among some long-legged broccoli plants and spinach growing alongside mounded chrysanthemums. Viola and chrysanthemum petals are edible, by the way.
Adding flowers also extends the life of the combos, Crawford said. "In many of my containers, with flowers that lived much longer than the vegetables, I simply cut the dead vegetable branches off and left the flowers to fill in the remaining space," she wrote in her latest book, "Easy Container Combos; Vegetables and Flowers" (Color Garden Publishing, 2010).
Most any kind of container will serve, provided it has the necessary openings for drainage. Having too much water in the soil is almost as deadly as having too little. It rots the plant roots.
