Cactus

Cacti are good house plants to consider because they are very low maintenance. Just because they do not take a lot of water does not mean that they don’t need water.

One type of cactus to consider is Astrophytum capricorne or goat’s horn, which is gray and spineless. They like warm temperatures but need to have good air flow (1). Another type is Cephalocereus, or columnar cactus. There are many species of columnar cactus, and they all require at least four hours of direct sunlight per day. They also need to be watered whenever the soil is dry (1). There are also several other types of cactus to consider.

Light

In general, cacti need to have direct sunlight for at least four full hours per day.

Watering and Fertilizing

Water only when the soil is completely dry and fertilize with house plant fertilizer only once a month (1).

Temperature and Pests

They need temperature at 60 to 85 degrees (1). Cacti are extremely prone to spider mites.

Welcome to Plants for Every Season

This Blog is intended to provide information to novice gardeners on how to grow houseplants and also how to grow outdoor plants. I hope it will also provide a point or two that might be of interest to long-time gardeners.

I have been gardening since I was little and I am currently enrolled in a Horticulture program. I hope to share some practical knowledge that I have gained in my course-work and while this Blog is not intended to be overly scientific, I will certainly try to make the information scientifically accurate as well as informative.

I hope you will find this Blog useful.
