Planting Barrel Cacti in Pots: 50/50 Sand and Potting Soil for Phoenix Patio

Barrel Cacti in Pots: Sand vs. Potting Soil?

Phoenix patio gardener has barrel cacti in potting soil, told to use sand. Asks which is correct.

Best Mix: 50% Sand, 50% Potting Soil

Greg recommends a 1:1 blend. Pure sand lacks nutrients; pure potting soil holds too much water. The mix drains well but retains some moisture and nutrients. Key: let soil dry completely between waterings.
