I live in the sunny desert of Idaho, zone 6. There's a little garden section next to my house on the south side. The ground is sandy in this place.
I've tried planting several things there.The first year, peas (which did well unil late spring, and I was able to harvest) and carrots (which were kind of woody tasting). What I really wanted was roses. It's a tiny space (2'x8') and I could fit three roses there, with strawberries as a ground cover. Well, the leaves didn't even bud on the first roses I planted. Almost all of the strawberries dried up right away. I thought I wasn't watering enough, (and planting too late in the season) so I tried it again this year. I planted much earlier. I watered more. One of the bareroot roses put forth leaves. The strawberries looked like they were going to do well. I left for the weekend, thinking they'd be all right. Three days later I returned to find only a few strawberries left (of the ~50 I planted) and the leaves on the rose shriveled up and crunchy.
I'm thinking my problem is two-fold. The sandy soil doesn't lock in any moisture. The house reflects the heat from the sun.
Only two things seem to grow well here- prickly lettuce and purslane. The previous owners had it filled with lava rock.
This is my new idea. I could get some sagebrush (a very natural plant around here) and use purslane as a ground cover. I'm also thinking of using prickly pear cactus down further along the side of the house. I also have one lone cotoneaster at the corner of the house that doesn't mind the dry.
I'm looking for any other suggestions. I also have a much bigger section I'd like things to grow in along the house (where I'm thinking of using the prickly pear)..
