Growing Berries in Arizona

I have learned this spring one simple lesson with berries in Arizona: if you want thriving plants, water thoroughly every day.

My strawberries and bababerries were beginning to struggle in the late-spring heat being watered only every other day. I am sad to say my blueberry has not survived, probably because I watered it only a couple times a week (as it was in an odd part of the yard).

As soon as I started the daily waterings, the strawberries and bababerries perked up, stopped browning at the edges, and started growing and fruiting again. The loganberry was doing well even bi-daily, but now it is growing even faster.

I keep the strawberry in a protected space, getting less than half a day of full sun. I tried a full-sun strawberry as an experiment, but, as I suspected, it died. The bababerries and loganberry are in full sun.

Blueberries

I picked up one blueberry at Home Depot as an experiment. Here is some info:

Blueberries could make a good fruit crop for home gardens since they require small space. At present, blueberry plants are not common in home plantings because the plants require highly acidic soil conditions for best results. Few backyard soils in Ohio are naturally acidic enough to grow quality blueberries. The grower of blueberries must, therefore, make extra effort to acidify the soil before plant establishment. Then, the acidity level must be maintained over the life of the planting. Due to the special concerns associated with the rather demanding soil requirements of growing the crop, the soil must be amended with organic matter and the pH must be corrected before proceeding to establish the planting.

Blueberry plants begin to produce fruit in the third season; however, they do not become fully productive for about six years. Once in production, it is necessary to protect the fruit from loss to birds.

Watering

Blueberry bushes have very shallow root systems and are very sensitive to water fluctuations. They need at least 1 to 2 inches of water per week. In dry seasons, supplemental watering is essential to obtain good yields of high quality products. However, do not apply water after early September unless soil is very dry.
Pruning

Blueberry plants normally do not need to be pruned for the first three years. Remove blossoms that appear in the year of planting and second year after planting to stimulate vigorous growth.

It is important to know the anatomy of a blueberry bush before attempting to prune blueberries (Figure 2). During the fourth year, the dormant plants should be pruned in mid-March. At this time, remove dead and weak branches and thin, terminal wood with small buds. Prune interior crossing branches to admit light to the center of the plant.

In the second through twelfth years, apply 1 to 1.5 pounds of ammonium sulfate (2 to 3 pounds of 10-10-10) per 100 feet of row each year for fertility and acidity maintenance. Apply 0.5 pound of the ammonium sulfate at bloom, and the remaining 0.5 pound 4 to 6 weeks later. If plant leaves become chlorotic, apply 2 to 3 ounces of ferrous sulfate or iron chelate around the base of the plants each year.
