Extreme heat Nevada Archives

While there are two ways to combat plant death-by-dehydration, it is probably too late for many in the U.S. Southwest, especially Arizona and Nevada, after a weeklong stint of record setting heat. (For those of you outside of the SW, there were high temperatures of 110-120F (43-48 celsius) for 8 days in a row and it continues.)

If you still have hopes for some plants in your garden you can do this:
1. Deep water plants more frequently than usual.
2. Hang shade cloth over your plants.

Realistically, however, dead plants — especially vegetables that were planted not long ago–are the new normal in Southwest gardens.

So what comes next?

For starters you can add those dead plants to your compost pile, so all is not wasted! And do not regularly fertilize any plants during summer months in desert climates. Even sturdy native plants are simply hunkering down and trying to survive until cooler weather arrives. Give them water, and in late summer, a tiny taste of fertilizer–that’s all.

Replanting right away is, obviously, not a good idea. Many gardeners now seem to be considering planting only natives when they replace what they lost this summer, but wisely they are waiting until Fall.

I’m thinking about pots on my patio overflowing with non-native Lantana (L. montevidensis) which seems to be able to survive almost anything and continue to flower.

Adios tomatoes and peppers

My vegetable growing experiment of this year will not be repeated. It has become a once-in-a-lifetime experience. I can buy organic veggies and support organic farmers while I eat healthy.

While I have stopped wasting water trying to help my sunflowers, tomatoes and peppers survive, I am still trying to help birds and other wildlife stay alive. I’d suggest that you do this, too.

Set out a shallow plant saucer filled with water and refill at least once a day. It can be a lifesaver for birds, insects and other creatures suffering from the intense heat and scarcity of water.

I’m not sure which creatures drink from this water source on my patio, but at least this Mourning dove has. You could also set up a trail camera to learn which wildlife comes to visit your garden.

Turning your garden into a kind of wildlife preserve may be the best use of that space as climate change brings hotter and dryer conditions. This extreme heat may not be the last.
