Some general guidelines for the care of drought tolerant plants.
Following is the Burning Bush one my favorite accent plants.
SOIL - A good rule of thumb is to have approximately 6 inches of good top soil which will allow for moisture to be held giving the roots an opportunity to grow. It may be a requirement to add organic material to the soil to add nutrients, hold moisture, and protect from heat and cold during the summer and winter months. Adding coarse sand and or gravel can improve drainage if the soil is too heavy.
WATER - It is important to note that the most drought tolerant plants require more water until they are established. It makes sense that the shallower the root system, that more water will be required, approximately one inch of water per week. Once the plant is established convert to a deep and less frequent watering which will cause the roots to grow deeper down into the soil. As the plants begin to grow and thrive on their own, gradually decrease the amount of water.
Following is the Vitex which is easy to grow and is a showy performer.
MULCH - Mulch can come in the form of leaves, shredded bark which you can prepare yourself or purchase bags of different colors from your local nursery. Although rocks, crushed granite can add an interesting texture to your garden design it should not be used around the draught tolerant plants because the rocks can damage the plants by reflecting the light and holding in the heat.
FERTILIZER - It is recommended that fertilizer is applied sparingly on drought tolerant plants. Check with your local nursery on how to best care for drought tolerant plants if you see discoloration.
Check your zone to confirm if the following drought tolerant plants require additional care during winter and summer months.
