The exact amount of vermiculite to be added to potting soil depends on the type of plants you are growing, their size, and the type of soil you are using. Generally, it is typically recommended to add about one to two parts of vermiculite to every four parts of potting soil.
For example, if you have 8 cups of potting soil, you should add 2 cups of vermiculite. If the specific type of potting soil already contains vermiculite, then it is not necessary to add more. Before adding the vermiculite to potting soil, it is suggested that you moisten the vermiculite first.
This helps it to mix in better and not become clumpy. Additionally, using a gardening fork or mixer helps spread the vermiculite more evenly.
Which plants like vermiculite?
Vermiculite is an inert, volcanic rock mineral used to aerate potting mixes in gardens or to store fertilizers in granular form. Numerous plant species enjoy growing in vermiculite, including roses, vegetable seedlings, and succulents.
Vermiculite is also useful for drought-tolerant plants and landscapes, helping to retain soil moisture, which is especially helpful during dry spells.
Vermiculite is especially useful for container plants because it creates small air pockets in the soil allowing oxygen, essential for root growth, to reach the inside of the soil. The mineral also increases soil drainage and helps retain the minimum amount of water needed for plants to thrive.
Vermiculite is attractive to earthworms, and encourages their activity which helps to aerate the soil and improve its structure, making it less prone to compaction.
The mineral also reduces disease risk and is resistant to rot and the growth of fungi. Other plants that favor vermiculite-enriched soil include palms, ferns, flowering shrubs, and many houseplants. Most forms of garden soil will benefit from the addition of vermiculite, but some need only small amounts, while others will prosper with a more generous blend.
Which is better for potting soil vermiculite or perlite?
The decision on whether to use vermiculite or perlite for potting soil depends on a few factors. The main one is what type of plants will be growing in the soil, as this will determine the soil’s nutrient needs.
Vermiculite has the capacity to hold more moisture and nutrients than perlite, which makes it beneficial for plants with higher nutrient needs, like vegetables and flowering plants. However, for plants with low nutrient needs, like cactus and succulents, perlite may be better.
Perlite has greater air porosity and good drainage, which is important for plants that don’t need to keep their roots wet. It also helps to lighten up the soil, allowing for better aeration.
In any case, both materials are preferable over traditional garden soil due to their consistent particle size, nutrient content, and water holding capacity. Additionally, vermiculite and perlite make it easier to achieve the right balance of air, water, and nutrients needed for healthy plant growth.
Ultimately, it’s best to combine both materials in potting soil, as this will create an ideal environment for any type of plant.

How do I make my soil light and fluffy?
Making your soil light and fluffy is an important part of achieving the best results in the garden. The key to achieving a light, airy soil is to improve soil drainage, increase water and nutrient retention, and support beneficial soil organisms.
1. Add organic matter: Adding organic matter such as compost, manure, or composted leaves is one of the best ways to improve soil drainage, increase water and nutrient retention, and support beneficial soil organisms.
Organic matter improves the soil structure by providing air pockets for drainage, loosening heavy clay, and helping retain moisture for a longer period of time.
2. Prevent compaction: Compacted soil creates an impenetrable barrier for water and roots and it can be difficult to fix. To prevent compaction, avoid walking on wet soil, cultivate shallowly, and add plenty of organic matter.
3. Aerate the soil: Aerating your soil opens it up and allows water and oxygen to penetrate the soil. You can aerate your soil with a garden fork or by using a tool, like a garden tiller, to create larger air pockets.
You may also consider adding a drainage system, such as French drains, to promote better drainage.
4. Add lime or sulfur: Soils can be too acidic or too alkaline, which can restrict plant and microorganism growth. Adding lime helps to bring the soil’s pH to a neutral state and also helps your soil more easily absorb nutrients.
Adding sulfur helps to lower the soil’s pH to a more acidic level, which can be beneficial for some plants.
By taking the time to improve your soil with organic matter and other amendments, you can make your soil light and fluffy. This will help to provide better drainage and encourage beneficial organisms, ultimately resulting healthier and more productive plants.
