Balloon Cactus Info
Balloon cactus is not a very common plant, but some retailers carry the succulents and the seeds are widely available on the internet.

Like many of the desert varieties, balloon cactus cannot tolerate frost and, in most climes, is suited only as a houseplant.
If you aren't a collector, you may wonder, “what is a balloon cactus.” You would recognize where it gets its name if you saw the plant. Pleasantly plump might describe this succulent. It grows fairly quickly and will eventually achieve 12 inches in height (31 cm.) in a container, but wild species can get 3 feet tall (91 cm.).
An obvious globose form with blue-green skin and deep ridges with both woolly and erect spines, under the right conditions the plant will produce rather large, bright yellow flowers. Unfortunately, the plant is threatened in its native regions of Brazil, Uruguay, Paraguay, and Argentina.
How to Grow Balloon Cactus
This plant prefers desert-like conditions, and the soil and site should mimic those environmental experiences. Use a good cactus mix or make your own with half top soil and half horticultural sand. You can also use regular potting soil halved with sand, pebble, and other gritty material.
This cactus is hardy to USDA zone 9 only, so most gardeners will need to grow this plant indoors and move outside just for summer.
Select a well-draining pot. Place the plant where it receives six to eight hours of sun per day but has some protection from midday heat. Use pebbles as a mulch to prevent moisture loss and keep the soil cool.
Balloon Cactus Care
Contrary to many gardener’s beliefs, a desert cactus does need water. In their native habitat, they get most of it during the rainy season and store moisture in the body. In cultivation, we must copy such conditions for a happy plant.
Water deeply when the soil is dry to the touch when you insert a finger down into the soil. In the winter, provide only spare moisture once per month if necessary. The most common problem with such plants is root rot from too much moisture.
Few pests will plague the plant but watch for mealybugs and certain boring insects. Repot the cactus every few years. Balloon cactus prefers a container only a bit larger than its diameter. This is an easy plant to grow and will provide you with years of maintenance free delight.
