Starting with a bare plot framed by an existing hedge (figure A), Gilmer intends to add patio trees and a variety of drought resistant plants. A checkerboard pattern of stone pavers, sundial and flowerpots will complete the layout. An efficient drip irrigation system will make this garden even easier to maintain. This project requires a lot of planting and some plant knowledge. Plus, the installation of the drip system can sometimes be tricky. Skill level: 3 (on a scale of 1 to 5, with 5 being the most difficult). Time needed: 12 hours Supplies: Drip system kit or:
- 10 half-inch emitters
- 10 quarter-inch emitters
- Half and quarter-inch drip tubing
Punch tool
Pavers/steppers
Sundial
Large pots (four)
Plant material
Fertilizer/compost
Ground bark/mulch Tools: Standard gardening tools (shovel, rake) Instructions: - You need to determine the drainage of your soil because many drought resistant plants are extremely sensitive to poor drainage. Dig a hole two feet deep and two feet wide.
- Fill the hole with water and monitor how long it takes for the water to drain (figure B). Drains in two hours: the soil has excellent drainage. Drains in a day: the drainage is marginal. Takes more than a day: drainage is poor. Mulch and Maintenance offers solutions for dealing with poor drainage. (More on how to improve poor drainage later.)
- Expert tip (Wendy Proud, horticulturist): Leaves have adapted to drought in many different ways. For example, small or needle-like foliage reduces the surface area of the leaf exposed to the sun. Some leaves have waxy cuticles to help hold water inside, while others are covered with hairs to keep the leaf cool.
