Cactus is most popular among garden plants, Cactus is well known for its ability to go weeks without water and even then when the time comes for them to get a drink they take in very little.

Cactus can be seen growing in many garden types especially rock gardens which gives that desert look. These plants come in so many styles and forms with an array of flower bloom but don’t be deceived because as beautiful as many of them are please do be very careful and handle with care not because they are fragile because they are not but because cactus can deliver a very painful experience with the thorns they produce.

Fertilizing is optional, I have seen these desert lovers growing so healthy with beautiful flower bloom without being feed with plant food.

Growing cactus from containers
When growing cactus from containers use a container that is large enough for your cactus plants, the container should have drain holes to allow excess water to drain. The soil should be a well-drained soil, as an added bonus it would be good to mix in some perlite or using cactus and succulent mix which can be purchased from your garden center or plant nursery.
Before installing your cactus in containers it is best to add about a two-inch layer of pebbles on the inside at the bottom of the container before adding the soil mix, this too is an added bonus to ensure that your plant has good drainage.
Once your cactus is installed in the container water thoroughly and do not water again until the few top inches of soil has dried. These plants are used to desert conditions so don’t overwater which can lead to root rot. The container should be placed in an area that gets full sunlight just take caution however where children and pets are involved. The use of a diluted fertilizer such as triple ten or 10-10-10 during the growing season will go a long way.
The growth and the care of cactus indoors
A great way to bring nature indoors is with the use of cactus when potting cactus for indoor purposes follow the seem example in the above section on growing cactus from containers. Water and fertilizer as discussed in the section on growing cactus from containers. Once potted the container should be positioned or placed near a south window to get sufficient light.
