July Gardening Tips for the Desert Southwest
- Hot, dry weather provides the ideal environment for spider mites, which frequently attack cypress, roses, and junipers.
- The tell-tale sign of spider mite infestation is stippling on upper leaf surfaces and webbing under leaves and along stems.
- A strong stream of water can often dislodge mites and not harm any beneficial insects that might be present.
A blast of water is also a good solution for cochineal scale, which resembles white bits of duff. It's especially common on purple prickly pear pads this time of year.
Lightweight horticultural oil, sometimes called summer oil, controls garden pests, like aphids, mites, scales, and mealybugs. When using, be sure to coat leaf undersides thoroughly. Before applying, it¿s best to water plants thoroughly.
