Surviving Arizona Summer

Seasons

August felt blisteringly long this year. With the nuclear heat, I didn’t go outside much. Just enjoyed the view of my landscape from indoors. Now that it’s September and the nighttime lows are coming down, it’s time to get outside and see how my plants survived.

Most of my established plants made it through just fine. The front yard irrigation timer shorted out and nothing got watered for about a month. Things started showing signs of stress, but I hand watered and got the system running again. The Spanish dagger and yellow bells showed the worst stress, along with a young slipper plant.

A young slipper plant has brown at the base of each stalk. It may be too damaged to survive.

In the back yard, I should have watered my smaller/younger cacti to help them through. Many showed signs of sunburn at the end of August. I didn’t notice any sunburn in mid-August when I looked at the yard, but at the end of the month, BAM! The summer rains washed away most of the basins around my plants, so last week I rebuilt them. Now I’ll be able to give them larger drinks. A little attention and everything will flourish.

Some heat stress is normal for this time of year. The brittlebrush and penstemon go dormant the entire plant may appear dead. My rose bush looks seriously neglected. We have a row of bell pepper plants in the garden that amazingly survived (with daily water), though the peppers roasted on the plants before we could eat them. I’m hoping the plants will be able to produce better through the fall, to make it worth keeping them alive.

Blue_agave_beetle

Blue agave that died from an agave beetle. Since I don’t treat my plants with insecticide, all of my blue agaves will eventually die and be replaced by the pups.

Our neighborhood experienced some saguaro carnage this summer as monsoon winds ripped through our street. A five foot saguaro broke off near the base. It had previously developed cracks from overwatering and couldn’t withstand the wind.

A reminder that even tough native plants can succumb.

The contracted pleats of my young saguaros indicated they need a drink. I’ll water them weekly until they plump back up. Remember that a saguaro will absorb all of the water its roots allow, so watering when the ribs are expanded can lead to the cracking that killed my neighbor’s plant.
