Keeping native plants healthy in June in Northern Arizona—which includes areas like Flagstaff, Prescott, and the Mogollon Rim—requires attention to heat, drought, wind, and elevation-related factors. Here’s a region-specific guide:
🌿 1. Water Wisely
June is typically one of the driest and hottest months before the monsoon season begins in July.
-
Deep Watering: Water early in the morning or late in the evening to reduce evaporation. Water deeply but less frequently to encourage deep root growth.
-
Young Plants: Newly planted natives may need weekly watering.
-
Established Plants: Once-established native plants might only need supplemental water every 2–3 weeks—monitor closely for wilting or leaf curl.
☀️ 2. Mulch for Moisture Retention
Apply 2–4 inches of natural mulch (like wood chips, pine needles, or bark) around the base of plants to:
-
Keep roots cool
-
Reduce water loss
-
Prevent weeds
Leave a gap around the stem/trunk to avoid rot.
🌬 3. Protect from Wind and Sun Scorch
High elevations and open areas can mean strong UV and dry winds.
-
Use shade cloth temporarily if plants show signs of sunburn (scorched, crispy leaves).
-
Windbreaks like native shrubs or fencing help reduce moisture loss.
🌸 4. Avoid Fertilizing in June
Fertilizer can stress native plants during hot weather.
-
Most native plants are adapted to nutrient-poor soils.
-
Wait until fall or early spring if fertilization is truly needed.
🐜 5. Watch for Pests and Disease
Dry stress can make plants more susceptible.
-
Check undersides of leaves for spider mites, aphids, or scale.
-
Avoid overhead watering, which can promote mildew and rusts.
-
Use neem oil or insecticidal soap for organic pest control, if needed.
🌦 6. Prep for Monsoon Season
June is the last big push before rains arrive in July.
-
Stabilize soil around plants to prevent erosion from incoming monsoons.
-
Prune dead or broken branches to reduce storm damage.
