did you know?

Cactus spines are actually modified leaves that have evolved to be spiny and sharp to repel predators and to conserve water better. As a houseplant, old man cactus grows to about a foot, but in the wild in Central Mexico, it can reach 50 feet tall.

general maintenance:

Repot young plants annually to a pot just slightly larger. Repot mature plants as needed.

pests/diseases:

Mealybugs can be a problem on new growth, and root rot may occur.

controls:

Spray mealybugs with insecticidal soap, following label directions. To control root rot, allow plant to dry out completely between waterings, and move to a room with 60°F minimum temperature in winter.

how to sow/plant:

Grow in pots filled with cactus potting mix. Set plants at the same level they were in previous pot. The soil level should be 1/2 to 1 inch below rim of pot to provide a water reservoir when watering.

water and fertilize:

When soil surface is dry to touch, water thoroughly until water flows out the pot's drainage holes. During growing season, apply fertilizer formulated for houseplants monthly, following label directions. Stop fertilizing in winter, when the plant is resting, and resume in spring as days lengthen.

garden hint:

On older plants, the silvery-white hairs may become brown due to dust and dirt. To remedy this, give your cactus a shampoo: Cover the soil with wax paper or plastic wrap, and gently comb the hairs with a mixture of water and non-detergent soap; rinse thoroughly.
