Fertilizer Properties

Cactus fertilizers are made of different ingredients like organic and inorganic. Here, I am going to share some insight, into which ingredients of fertilizer, you should use in your moon cacti garden. Hope it will save your time and tension.

Natural vs. non-natural

  • I am a lover of nature and a pure environment. That’s why I always prefer to use organic fertilizer.
  • Organic fertilizer is safer than inorganic fertilizer for your future generation.
  • The more important point is that your moon cactus loves to absorb slowly organic nutrients for its health and beauty.

Slow Release vs. Quick Release

Nitrogen is the very vital ingredient for the growth of moon cacti. The good news is that slow-release fertilizer has more nitrogen than quick-release fertilizer. Again another side effect of quick-release fertilizer is that it will burn out your cacti roots. Because quick-release fertilizer has salts that draw the moisture out of cacti roots.

Liquid Fertilizer Vs Granular

  • Moon cactus fertilizers can be sold either in liquid form, as a powder, or in granules.
  • As cacti gardeners, you should know the difference between liquid fertilizers and powders. For example, liquid fertilizer is a solution that contains an active ingredient. Another type of fertilizer is a powder, which needs to be mixed with water in order to be watered into the potting medium of your plant.
  • Liquid fertilizers are the most effective type of fertilizer as they provide the nutrients to plant roots quickly. They can also wash away easily and so repeated applications may be necessary.
  • Granules are a popular option for growing plants. They provide easy, yet effective nutrition to your plants and can be applied directly to the soil or potting medium. They will provide slow-release nutrients. Granules can provide nutrition for up to nine months.
