As one of the most prolific native plants in Albuquerque landscapes, the humble cactus delights in its many shapes and forms. Cacti provide a diverse choice from small, squat varieties to large flowering types. Varieties with long, needle-like spines can provide security when placed under windows, while less dangerous types work better along walkways and paths. While many of the cactus seen in local yards are native to the region, some more exotic types can also grow well in our dry, mild climate.

Three Pillars of Cactus Growing

Cacti require minimal moisture, warm temperatures and light fertilization. Most varieties grow best with benign neglect. The most common causes of plant decline are over-attentive gardeners that water or feed the plants too much. The cactus plant evolved to deal with harsh climates, so too much coddling compromises the health of the plant.

Irrigating Correctly

The minimal watering requirements make most cactus varieties the star in Albuquerque xeriscaped yards. When grown in sandy, well-drained soils – of which we have an abundance – cacti only require a light watering during extended periods of no rain. In general, this means the plants need watered lightly every two to three weeks during our summer drought period. The late summer monsoons usually provide enough moisture to carry the plants through the winter months.

Temperature

Albuquerque temperatures can sometimes get too low for non-native varieties during the winter months. Planting these cacti in an area with southern exposure prevents frost damage, since these areas warm up quickly in the sun. Avoid the tropical varieties, though, since these cannot tolerate our 30 degree winter weather.

Fertilizing

As a rule, outdoor cacti do not require fertilization. The plants get plenty of nutrients from the soil and from the fertilizer run-off from nearby lawn areas. Flowering cacti may fail to flower if fertilized, since flowering often occurs when the plant feels stressed.
