Growing and Caring for Tall Cactus

While growing and caring for tall cacti may seem intimidating, they are generally easy to maintain. Here are a few tips to ensure your cactus thrives:

Light

Most tall cacti prefer full sun, although some varieties can tolerate partial shade. If you're planting your cactus outdoors, make sure to choose a spot with plenty of sunlight. If you're growing your tall cactus indoors, place it near a sunny window or under a grow light.

Water

Cacti are adapted to survive in arid environments and do not need much water. During the growing season (usually spring and summer), water your cactus once a week. In winter, when the plant is dormant, cut back on watering to once every three to four weeks.

Soil

Tall cacti require well-draining soil to prevent root rot. You can buy a pre-made cactus mix or make your own by mixing sand, perlite, and potting soil.

Fertilizer

Cacti require very little fertilizer, so avoid overfeeding. During the growing season, you can fertilize your cactus once a month with a liquid cactus fertilizer.

Propagation

Tall cacti are easy to propagate through cuttings. Simply take a cutting from the parent plant and let it dry out for 24-48 hours. Then, plant the cutting in well-draining cactus soil and water sparingly until it develops roots.
