Verdict: the best containers/pots for growing cacti are ceramic (terracotta and glazed), plastic and hanging (can be ceramic or plastic as well) pots. Only use glass containers for a short period of time (or avoid using at all) and don’t use metallic pots, either.
Thereof, do cactus need special pots?
Cactus plants usually don’t require big pots. However, if you choose a tiny pot, it will constrict the roots leaving no room for the soil. On the other hand, if you choose a vast container, you will- most likely over water the plant. Therefore, it’s incredibly essential to choose just the right size for the cacti.
Also, can you plant a cactus in a bowl?
Cacti and other succulents have shallow roots, so the dish only needs to be 3 in (8 cm) deep. A 9 in (23 cm) terra cotta bowl works fine. It doesn’t need to have drainage holes because the sandy potting mix is fast-draining. Just be careful not to overwater.
Should I put my cactus in a bigger pot?
Most cacti have shallow roots and grow slowly, so choose a shallow container. You don’t need a deep pot or a very large one.
Available in almost any shape and size, cacti flourish in both garden beds and containers. If you choose to grow your cactus in a container, the size of the container must match that of the plant. A container that is too large or too small can stifle the cactus’s growth and contribute to the plant’s demise.
You will know when to repot a cactus plant if you see roots coming out the bottom of the container. This indicates it is overly root bound. Most cacti find small spaces very cozy and can stay in their container for years. The sight of roots will let you know it has expanded too much and will need repotting.
Use the method employed by expert cactus growers and water from the bottom. About once per week during hot weather, or whenever the pot feels light, place the potted cactus in a shallow saucer filled with about 1/2 inch of water and leave it in the saucer for about 1/2 hour or until it sucks up the water.
When to repot
Cacti should be repotted as soon as the roots begin to show through the drainage holes at the bottom of its pot. As a general rule, fast growing species should be repotted every two to three years and slow growing species every three to four years.
