It's summer in the desert and that means intense heat and little in the way of gardening. Each morning, and I am usually up by 5:30am, I open the patio doors and step outside to sample the temperature. On a good morning the temperature will be around the 70 degree mark. Maybe a little lower and there will be a slight breeze. I must make the choice between going for a walk and doing some gardening. All must be done by 9am.We make the most of these early morning hours.
No-one would doubt that this part of the Sonoran desert is not a beautiful place but if you were to look around and assess which plants are native and do well here without irrigation you would find a limited palate. Plenty of small trees, all with their small leaves ideally suited to desert heat, and they do put on a magnificent show in the spring, and a number of cactus including the saguaro, lots of fishhook barrel cactus, a sprinkling of echinocereus and small mammillaria, a few yuccas prickly pear, ocotillo and the very successful cholla. The mammillaria are quick to respond to a little sprinkle and lowering of temperatures.
But few of the cactus you may come across at the local cactus nursery will you seen the wild desert landscape. And we certainly have plenty of the finest in the country. When I visit Bach's cactus nursery I ask them which cactus can survive everything that the desert has to throw at it. They show me a small table of plants both summer and winter hardy. That said there are some additional plants that do well here and add some variety to the home landscape particularly as many have a drip irrigation system. I can't say that I have ever seen this bunny ear cactus, Opuntia microdasys, growing wild ( native to Northern Mexico) but it is beyond happy in the summer garden. Nor is it eaten by critters. It is best suited to an outdoor planting where the gardener can keep well away from it. I once walked out of my old greenhouse with a pot of this plant and the door swung to and the cactus promptly hit me in the face leaving behind thousands of tiny glochids.
This euphorbia, Moroccan mound, Euphorbia resinefera, is also a success story. Slow growing but also unlikely to be eaten by critters. Not always easy to find at a reasonable price because it takes so long to grow to a decent size.
One trick that the growers do is to put three smaller ones in a larger pot. When you come to plant they simply fall apart. The best way to overcome that is to dig the hole, cut the bottom out of the pot, slip the plant in and cut away the rest of the pot. You need a strong utility knife to cut through the plastic but this is the way I have seen the landscapers plant their big pots and cactus in particular.
When I began writing this in late June I had no idea if we would ever get away this summer. We did, making the journey up to the Wood River valley in Idaho where we were able to spend 4 lovely weeks on our favorite campsite.
But I dreaded what I would find when I got home. The hoped-for monsoon rains had been sparse and never in our area and they are so desperately needed-especially after the dry winter. I scouted the vegetation as we approached home and noticed the ocotillo were in full leaf. That was a good sign as ocotillo will drop their leaves in drought and as soon as it rains they will leaf out again, doing this multiple times in a year. There had been rain at our house because I could see flowers on the Texas sage had bloomed and withered. Those plants that had made it through dry June and July were springing back to life. I had lost several plants in pots........some had been eaten. There were plenty of holes at the base of plants where small desert critters had sought coolness. And now another rain this week has really brightened up the desert with trees and bushes coming to life.
barrel cactus are bloomingEverything has taken a big drink. Will it be enough to see the desert through the rest of the summer remains to be seen. And there is still a lot of summer left.
