What to do in July 🌧️ , cause of yellow leaves πŸ‹ , my free plant mishap 😹 , & more 🌡😎


Hi, Desert Gardener!

July in the southwest is a month of changes. The monsoon officially started June 15, but the first rains usually arrive in early July. Monsoon storms bring welcome rainfall, humidity, and cloud cover β€” all a great relief for your plants.

But it’s not all good news for desert gardeners. Monsoon storms can bring flooding, hail, dust storms, and damaging wind. And an increase in moisture leads to more insect pests, plant diseases, and weeds.

All these changes mean there are changes in gardening tasks this month, as well. So be sure to check out our July's "What to Do in the Garden" guide.

What you'll find in this week's newsletter:

  • What to do in the garden in July
  • Featured Plant: Mexican petunia
  • Yellow leaves, green veins: what it means, what to do
  • Find free plant stands
  • Upcoming gardening classes & events
  • and more!

My Free Plant Stand Find

A few months ago, I was thrilled to have found a "free little plant stand" while on a bike ride. And it had a Mexican petunia! (Oh, happy day!) But on the way home, I hit a substantial bump in the bike path and the container flew out of my pack into the street. Most of the roots and leaves broke off. πŸ₯Ή But I planted it anyway, and it started leafing out within the week. It continues to do well in spite of its bumpy start. Mexican petunia is one tough plant!

Want to find a free plant stand near you?

I love the free stand concept. If you live in Arizona, California, or Texas, check for a stand near you with this interactive map or visit Garden Exchange Stands. If you live elsewhere, do a search for "plant stands" or "garden exchange stands".
