Cacti are one of my favorite types of plants to grow inside all year and outside in summer. Unfortunately, the ambient air tends to stay moist during most seasons, a condition which makes cacti unhappy. Cactus potting soil can enhance drainage, increase evaporation and provide the dry conditions that cacti favor.
Cactus' are used to desert conditions with minimal water. If you water too much, you can kill it. The important thing is to look at it and see if it begins to sag or look deflated. The soil should be about 50% sand for quick drainage.Cacti and succulants that are planted in pots should be watered sparingly about once a week and less if yellowing occurs as pots evaporate more quickly. Each variety and its size and age can change its water requirements.he important thing is to look at it and see if it begins to sag or look deflated.
