Xeriscape Maintenance Tips for October

Why October Matters for Xeriscapes

October is a critical month for xeriscape gardens. The work you do now sets the stage for a healthy, water-efficient garden next spring. Proper fall maintenance reduces water needs and prevents winter damage.

Pruning Drought-Resistant Plants

Cut back spent perennials like lavender, sage, and Russian sage by one-third. Remove dead or diseased branches from shrubs. Avoid heavy pruning of evergreen xeriscape plants until spring.

What to Prune Now

Spent flower stalks on agastache and salvia
Dead branches on desert willow
Faded blooms on yarrow and sedum
Overgrown ornamental grasses (leave seed heads for wildlife)

Mulching for Winter Protection

Apply a 2-3 inch layer of gravel or crushed rock mulch around xeriscape plants. Avoid organic mulch near succulents and cacti, as it retains too much moisture. Gravel mulch insulates roots while allowing water to drain quickly.

Irrigation System Check

Drain and winterize drip irrigation lines before the first freeze. Check emitters for clogs and replace damaged tubing. A well-maintained drip system uses 30-50% less water than sprinklers.

Planting Opportunities

October is ideal for planting new xeriscape specimens. Cool temperatures reduce transplant shock, and fall rains help establish roots. Consider adding native wildflower seeds for spring blooms.
