Tips on Growing Cactus in Zone 5
Cacti like lean soil with an alkaline or neutral ph. Don’t bother improving the soil with peat, manure, or compost. Plant cactus in well-drained soil. Cactus planted in moist, poorly drained soil will soon rot. Raised or mounded beds will improve drainage if winter rain or snow is frequent. Mixing native soil generously with coarse sand will also improve drainage. Don’t mulch the soil around cacti. However, you can top-dress the soil with a thin layer of pebbles or gravel. Ensure the planting area receives plenty of sunlight year-round. Water cactus regularly during the summer months but allow the soil to dry between waterings. Discontinue watering in autumn so cacti have time to harden off and shrivel before winter. If possible, plant your cactus near south or west-facing walls, or near a concrete driveway or sidewalk (but safely away from play areas or other places where the spines can cause injury).
