Spring Time

Spring is just around the corner. The average day of last frost in Tucson is March 15Th. It looks like we still might have one or two frosts this year. There are two storm systems coming this way with rain. If it only gets to the low 60s F for high temperature, it might get down to the low 30s F that night. This will depend on whether the clouds leave or not and what time they leave. If the clouds are gone by the afternoon on a cool day and there is no wind that night, conditions will be right for a frost.

Right now gardeners are getting ready for a big spring planting. You can still plant cool season annual flowers and vegetables through March. Warm season annuals can be planted after last frost along with warm season vegetables. If there is no cold weather in the seven day forecast by March 15th, its probably a good bet that we won’t have any more frosts late because off the warm weather we have been having. There are no guarantees, but at a certain time common sense has to prevail. Among the warm season annuals are Marigolds, Periwinkle (Vinca), Portulaca, Moss Rose, Golden Fleece, Gomphrena, Sunflowers, Salvias, Lureopsis, Gaillardia, Monarda,  and Cosmos. Vegetables include Corn, Beans, Melons, Cucumbers, Squash, Zucchini, Okra, Tomatoes, Peppers, and Eggplant, Corn, Beans, and Okra should be grown by sowing seeds directly into the ground.

All others can be planted from transplants. It is a good idea to prepare the soil with amendments and compost a couple of weeks ahead of planting.  Another suggestion in vegetable gardens is to plant a few plants that draw bees to the garden to insure good pollination. Porthlaca and Moss Rose are good attracters of Bees. Tomatoes, Peppers, Eggplant, Melons, Squash, and Cucumbers require pollinators to produce fruit, Vegetable garden should be watered daily and should be in full sun. Check seed packs for harvest times. A note: Summer and Winter squash are planted at the same time (usually before July), the difference is that summer squash are harvested in Summer, Winter squash in Fall or Winter.
