Bunny Ear Cactus Soil

Bunny ear cactus does not have high requirements for nutrients, but it is afraid of ponding. Therefore, when we mix the soil, we mainly focus on the ventilation and drainage performance, so we can appropriately supplement certain nutrient soil. Therefore, we cultivate Bunny ear cactus mainly by using granular soil and nutrient soil, We can also directly use pine needle soil to cultivate Bunny ear cactus.

Bunny Ear Cactus Light

Bunny ear cactus is a plant that likes sunlight. It can grow better only when it is exposed to sufficient sunlight, especially in winter. So it's best to place Bunny ear cactus in a sunny place at home.

At the same time, we also need to cut off the small stem nodes in the first segment of the cactus. Because some weak stem nodes grow on the bunny ear cactus plant, they should also be pruned and removed, so as to avoid absorbing excess nutrients in the cactus.
We only need to keep the two buds on the stem node of bunny ear cactus, and trim the excess. After the cactus blooms, we also need to trim the withered flowers. The specific Bunny ear cactus pruning method is as follows.
Bunny ear cactus top stem and leaf pruning: generally, we raise cactus at home, and its growth height will not be too high. Therefore, we only need to cut off the cactus growing at the top of cactus plant, so the advantage of doing so is to reduce the height of cactus, which grows rapidly.
We can also trim the weak stems on site. During the maintenance period, some weak stems and leaves may appear on the overall pillar of bunny ear cactus due to other maintenance reasons. If they are not trimmed in time, these stems and leaves will absorb other nutrients in the cactus. In addition, on the stem nodes built by cactus, we also need to properly trim the redundant buds of bunny ear cactus, just keep two.
