“May is so beautiful: orchards are fair; branches of fruit trees make gardens of air. Flowers of fragrance bloom in the light; fall like the snowflakes showering white. Orchards of heaven grow with a grace, and like a blessing, perfume the place. Each tree in blossom, each lovely spray, in this month of Our Lady, bring glory to May.” Helen Maring, May in Bloom.

The daytime temps have reached the 90’s while the nights offer a comforting 60’s and 70’s regime. Such weather offers an encouraging opportunity to get outside and enjoyably work the landscape. Are you looking for techniques and strategies to make the best choices in your landscapes? If so, then think sustainable landscaping which is a sensible and economical approach for our south Georgia yards. Furthermore, it promotes an environmentally-friendly approach while affording us comfortable and enjoyable outdoor living spaces.

At the very core of sustainability lies drought tolerance. A plant is drought tolerant if it can survive a dry period of two to three months without supplemental irrigation. Many of our native plants in regions experiencing such conditions are drought tolerant. To reduce the need for supplemental irrigation in your landscape, drought tolerant plants should be used. If you want to minimize long-term watering, be sure to use native or sustainable plants for our area.

A brief list of drought tolerant plants by common and botanical names has been generated for your use. The botanical name eliminates any confusion that might be created by variations in common names between locales.

Just get outside enjoy your spring gardening! And remember to feed and water the birds!
