Just be cautious of extreme heat, especially during the summer months.
Overwatering

Signs of overwatering include yellowing or browning of the lower portion of the cactus, soft or mushy spots, and a musty or rotten smell. To prevent overwatering, it’s essential to let the soil dry out completely between waterings. Only water the cactus when the top inch of the soil feels dry to the touch.

To properly water your cactus, thoroughly soak the soil until water drains out from the bottom of the pot, and then allow it to dry out before watering again.

In addition to pests, diseases like root rot and fungal infections can also cause yellowing. If you suspect pests or diseases, it’s essential to take immediate action.
