Are Gooseberries Heat Resistant?

Heat Tolerance

• Gooseberries thrive in U.S. Department of Agriculture plant hardiness zones 3 through 5 but languish in hot climates where growth can be stunted and the fruit often become scalded. Extended periods of very warm weather -- with temperatures above 86 degrees F. -- might cause the shrubs to lose their leaves, according to the Colorado State University Extension.

Solutions

• Gooseberries grow best in full sun, but they'll tolerate partial shade, which is preferable if you live in an area with hot summers. In dry, hot areas, gooseberries grow better in clay soil than sandy soils because clay soils tend to stay cool and moist. Mulch the ground with 2 inches of wood chips to moderate soil temperatures and water frequently during hot weather. In hot climates, plant gooseberries on the north side of the house or in a location that gets northern exposure.

Varieties

• Some gooseberry varieties are more adaptable than others. European varieties have the best flavor, but they're finicky about growing conditions and they're prone to disease. American varieties are more adaptable and vigorous. They're also the most commonly available. Try "Poorman," a hardy red variety often recommended for home gardens, or "Captivator," an almost thornless variety that produces pink to purple fruit.

Alternatives

• Gooseberries, and their cousins, currants (Ribes spp.), grow best in cool, northern climates. Gardeners in USDA zone 5 will need to protect gooseberries from hot summer temperatures. South of USDA zone 5, your best bet is to choose a berry suited to mild climates. Blackberries (Rubus spp.) thrive in warm, moist regions. A few new blackberry varieties are suited to USDA zone 5, but most grow best in zones 6 through 8, making them an ideal substitute for gooseberries in those areas. (ref. 5, 6)
