🌵 Arizona Gardening Tips – May

☀️ 1. Water Smart (But Deep!)

• Start watering early morning or late evening to minimize evaporation.

• Deep watering is key—especially for trees and shrubs. Aim for 18–24″ deep.

• Adjust irrigation systems for longer run times, less frequently.

🌼 2. Plant These in May

Still time to plant heat-loving veggies and flowers:

🌿 Vegetables & Herbs:

• Okra

• Sweet potatoes

• Basil, oregano, mint

• Chiles & hot peppers

• Armenian cucumbers

🌸 Flowers:

• Vinca

• Zinnias

• Marigolds

• Portulaca

• Cosmos

• Sunflowers

🌴 3. Care for Palms & Citrus Trees

• Feed palms with palm-specific fertilizer containing manganese & magnesium.

• Deep water citrus trees every 10–14 days.

• Remove suckers from the base of citrus trunks.

✂️ 4. Light Pruning Only

• Prune spring-flowering shrubs (like Texas sage or oleander) after they bloom.

• Avoid heavy pruning as it can stress plants going into the hot season.

🐛 5. Watch for Pests

• Keep an eye out for aphids, spider mites, whiteflies, and caterpillars.

• Use Neem oil or insecticidal soap in the early morning if needed.

☂️ 6. Mulch for Moisture & Heat Protection

• Add or refresh 2–3 inches of mulch around plants to keep soil cool.

• Use organic options like wood chips, straw, or compost.

🌞 7. Provide Shade Where Needed

• Young veggies, herbs, or transplants may need shade cloth (30–50%) during the hottest part of the day.

• Even desert plants appreciate a little break from the intense afternoon sun!

🗓️ Bonus Tip:

Start prepping for the summer monsoon season—check your drainage, prune trees for wind, and stock up on mulch and soil builders.
