Cacti Species Popular as Houseplants
When planning to keep cactus plants in the house, you need to know the basic information about the species. There are basically two varieties preferred as houseplants: the'desert cacti', such as Golden barrel cactus, Column cactus, etc., and 'forest cacti', such as Easter cactus, rat-tail cactus, etc.
Desert cacti, as their name suggests, are native to the arid regions of the world. These species are the ones which are usually covered with spines and hair, an adaptation to survive water scarcity.
On the other hand, forest cacti are normally found in wooded areas of temperate and tropical regions. Other common species include the Giant saguaro cactus, Christmas cactus, etc.
Cactus plants require a copious amount of sunlight, so experts recommend keeping them near a south facing window. Some varieties of cacti only flower when they receive ample sunlight. You may have to keep the particular species outdoors, so that it basks in the sunshine to produce beautiful flowers.
One should never use cold water for cactus and, more importantly, should never pour water on the top of the plant. Though relatively less, they do require fertilizers. It doesn't matter if the soil you use to plant them is low in nitrogen, but it should be high in potassium and phosphorus.
Both varieties have different needs and growing conditions. Forest cacti need more water than their desert counterparts. You need to keep the soil moist throughout, but for desert cacti, you need to let the soil dry completely before you water it again. Owing to these differences, different varieties of cactus cannot grow together in a single container.
Growing cactus can be easy, as long as you pay attention to things like re-potting and pruning. As an amateur gardening enthusiast, you should ideally go for species like the orchid cactus, which are easy to care for. Basically, these houseplants grow best when they are unattended.
