This year, it seemed that conditions were ripe for an attack of White Flies at the Clifton Place Garden. Over our years of existence, we have had mild aphid infestations. But nothing to the extent experienced this year with white flies.Liz, one of our gardeners, realized a wonderful yield of Kale in her plot. But her success was greatly overshadowed by a persistent fight to rid the plant of the infestation of white flies. Because The Clifton Place Garden strive to maintain a pesticide free garden, Liz's option to fight the problem was limited to washing the plants regularly with water and installing sticky pads. Ultimately, Liz would lose the battle. Like most of our members, she is not at the garden often enough to wage a determined battle against the little creators.
What we should have done was companion planting. Companion planting is the long practiced organic growing technique where beneficial insect-repelling plants are grown with other plants to fend off insects they attract. In Liz's case, for example, we could have planted, together with the kale, nasturtiums and marigolds to repel the white flies. Were we to have had an infestation of aphids we could have grown garlic, mint, or catnip. (more info: http://docs.google.com/Doc?id=ddp7j7xj_0dx6v2fhc)
There are other benefits that are gained from companion planting. Beyond the benefits of pest
control companion planting can help with nutrition and moisture management of the soil. Some crops concentrate nutrients in their tissues. Others move nutrients from the subsoil to the above ground parts, that in turn is made available to subsequent crops upon decomposition. Some plant increase potassium levels, while others (particularly legumes) gather unusable nitrogen in the air and convert it to usable nitrogen. This is probably what the farmers at the the Stone Barn Center for Food & Agriculture in Westchester, NY, have in mind when they choose to plant corn is plant together with beans and squash, and melons are allowed to grow in grassy fields.

Going forward, companion gardening will become an integral part of our growing methods to both manage pest and ensure quality yields. Given that the average size of a gardener's plot is 4' x 6', with proper planning and companion gardening, a greater amount of crops can be grown in a season. Realizing greater results through natural processes is clearly smart planting.
