How to Grow Cactus Plants?

Many people opt not to grow cacti from home, with most preferring to purchase a baby potted cactus and nurse it into full size over time. But if you really want to know how to plant a cactus then look no further. Here is a simple step by step guide to planting a cactus at home.

  1. Step 1. Seeds – If growing cactus from seeds, the first step you need to do, is to fill a small pot with well-draining compost or cactus soil and place the seeds on top with a little room between each seed. Cuttings – If growing cactus from a cutting, ensure the cutting is well dried before placing it in a pot.
  2. Step 2. Seeds – Cover the seeds with a little more compost and leave your plant in a warm, sunny area. Cuttings – Place cutting (cut side down) in the soil so that it can support its own weight – wear gloves to avoid spikes catching your ski. Move your potted cactus to a well-lit area.
  3. Step 3. Seeds – Water only when the soil is dry so as not to drown your seedlings, but make sure you check on them regularly, as it is possible to dehydrate your plant. Cuttings – Water your cutting as you would a seedling (see above).
  4. Step 4. Seeds – After many months, little seedlings should be growing and will be ready to move into a more suitable home. Transfer your cactus using a fork and make sure you are wearing gloves to not prick yourself on the spikes. Place your seedling in a larger pot by itself to give it plenty of room to grow. Again your soil should be the same well-draining or cactus compost as before. Cuttings – Keep your newly growing cactus in in-direct sunlight for the first few months, then move to a location with access to more sunlight once your baby cactus has grown a bit.
  5. Step 5. Both – Tuck in your baby cactus with more soil and water to ensure it is in a moist environment. Care for your cactus following the fool-proof tips in this article.

Houseplants thrive in conditions similar to those of their natural environment so it will come as no real shock to realize cacti need plenty of sunlight. Many indoor cactus plants crave up to 6 hours of direct sunlight per day – but be careful they don’t start to yellow, as this means they are too exposed to sunlight.

Like other houseplants, sunlight isn’t the only basic need of an indoor cactus. They still need water. Unlike other houseplants, cacti don’t require watering as often as most.
