Drought Herbs

Select and Grow Herbs in Arid and Drought Conditions

Global Warming - whether fact or fantasy, is a distinct possibility, just like the Ice age they were predicting a few years back. Some Scientists assure us that both Al gore and Chicken Little have good points and perhaps it is getting warmer as the sky falls.

Gardeners in drought plagued regions have good cause for alarm and are looking for solutions to keep on growing their prized vegetables and herbs, while minimizing water usage. Hardy herbs that resist drought are available, you may have to look a tad harder. Techniques and tactics to optimize your herb gardens performance under arid conditions are also feasible.

Many herbs we commonly use are already genetically pre-conditioned to tolerate arid conditions. They evolved over the Centuries from their native Middle Eastern and Mediterranean climates to prosper under what we would consider less than optimal conditions. The majority of herbs aslo do not have the rigid fertilization requirements that we commonly associate with vegetable gardens.

A modest amount of fertilizer amended into the soil will help ensure the success of your herbs. Organic Compost contains some of the nutrients they will require and combined with a light mulch will help provide a soil composition that allows for aeration and drainage. If you have a clay soil, some sand amended into the garden bed is also advisable.

Adding several inches of organic mulch at the base of plants optimizes moisture retention. Mulch the bed after planting to aid in water retention and weed retardation.

One of the natural elements that all plants require is silica aka silicon. Silicon is proven to enhance drought and heat tolerance in plants. It is for the most part extremely abundant in nature, second only to oxygen. It makes up about 1/4 of the Earths crust. It is a naturally occurring element found in soil. It strengthens the plants cellular walls, improves the plants tissue strength and ability to withstand adverse climatic conditions. There are several ways to ammend silicon into your garden bed.

Drip irrigation uses 30 - 50% less water than conventional watering methods, and uses it more effectively. Drip systems will also inhibit the encroachment of competing weeds as the water is delivered to precise locales aimed at where your plant can utilize it. See Drip Irrigation for Drought Gardening
