March 2022 Gardening Tips

Last month had such variable weather that I hope you were able to take time on  of  the warm days to plant strawberries, raspberries and blackberries if you didn’t do it last fall. All your berries will appreciate a heavy straw or sawdust mulch to control weeds and conserve moisture this summer.

In a sunny south facing window, your greenhouse or a cold frame continue to sow lettuce, scallions, cabbage, collards, and broccoli. In spite of the variable weather we are started some extra early tomatoes, peppers and eggplant  to get a head start on the summer season as soon as the ground starts to warm. We will sow our main crop of nightshades by April 1. Outside we are sowing early radishes, spinach, turnips, carrots directly in the garden and covering with spun polyester row cover. Presoak beets seeds 1- 4 hours, sow 1/2″ deep, tamp soil when covered. Last date for sowing fava beans is 3/14.  When the Forsythia blooms, sow peas, only 1/2″-3/4″ deep (soak or pre-sprout to get a head start).  To support dwarf peas you can sow 1 oat grain per 5 peas.

Prepare to plant your Irish potatoes as soon as possible after St. Patrick’s Day by green chitting. The practice of pre-sprouting seed potatoes before planting encourages early growth. It is widely used abroad, but less known to Americans. Chitting is simple. Spread the seed tubers in boxes or flats one layer deep with the seed end up. Look closely at a seed potato and you will notice one end was attached to the plant. The other end has more eyes from which sprouts emerge. The end with the eye cluster is called the seed end. Place your flats in a warm area (70 degrees) where light is bright but indirect. The warm air stimulates the development of strong sprouts from the bud eye clusters, which, in the presence of light, remain stubby and are not so easily broken off.  Allow 1 to 2 weeks before planting.

As soon as your potatoes are in, it’s time to start the main crop of tomatoes indoors.  Tropic is a great tomato for disease resistant, blemish free fruits placing high in a University of Georgia.  No Matter how dry it is plan your irrigation and unfurl your hoses; be certain it’s all in running order because a dry spring may be right around the corner.  Whenever the soil in your garden is dry enough spread compost and till beds for outdoor planting that will begin in earnest next month.
