What is potting soil?
The standard potting soil includes soil, sand, and humus that account equal part of the mixture. This combination could be used for almost potted plants.
Today, commercial potting soils are a bit different. Their recipes consist of sphagnum peat moss or calcined clay to absorb water in the soil, composted organic ingredients to provide nutrients, and vermiculite or perlite to improve drainage.
How to choose the best potting soil
The best potting soil for your needs depends on several factors such as the types of plants or the properties of soil. As your plants could benefit from different kinds of soil, you need to take a close look to potting soil to choose the right fit for your garden.
The mix of ingredients
One of the best ways to find out differences among a variety of commercial products to buy the best potting soil is reading information on their labels. Doing that, you could have an understanding of their content and, then, purchase the right one for your plants.
Different mixtures could improve the condition of drainage and hold nutrients of plants at different levels due to the variation of the proportion of perlite, peat moss, and vermiculite in the potting soil.
Another thing that you need to notice is that sand might be found in some specialty mixes, but it does not help to hold moisture and nutrients well, not mention to the fact that it could interfere with drainage.
You also need to determine the amount of fertilizer in the potting soil. The period for which fertilizer could feed the plants depends on the nutrients levels that it adds to the soil.
The place you grow your plants is also the consideration when choosing the best potting soil. It is because depending on the amount of sunlight; your plants would lose the water quickly or slowly and need different soil.
Plants that are grown in full sun would be suitable for medium-weight soil holding water well. Meanwhile, plants in the shade only need lighter soil due to the different water retention.
Organic or non-organic potting soil
It is not a problem to choose organic or non-organic potting soil as both of them are suitable for your potted plants, with the exception of the use of fertilizer in the non-organic one.
In a single gardening season, the ingredients of non-organic mixes could provide nutrients for your plants. However, organic potting soil includes materials that could be used for your container growing over many seasons.
If you want to choose the organic potting soil, you should check OMRI listed. It could confirm with you that there is no non-organic ingredient in the products you want to purchase.
Best potting soil for different purposes
Although all-purpose potting soil could be the right choice for almost plants that you want to grow in pots, you should consider other kinds of potting soil that are suitable to some special case.
If you want to grow cactus and other succulents, African violets, orchids or roses, the plant-specific potting soil could match well with the plants’ need and provide plants with the exact condition to grow the best.
Starting to grow a new plant and transplanting seedlings would need different mixes of potting soil. While seed-starting mixture could nurture the seedlings until they are ready to be transplanted, the transplanting mixture could help the seedlings keep hydrated after the transition and have a healthy growth.
What to do if you cannot decide to buy which one
If you cannot decide which is the best potting soil for your plants, you could buy two or more types of soil and try them before concluding how they are effective.
Firstly, you grow your plants in all of the kinds of potting soil you purchased. Then, you monitor the growth and overall health of your potted plants. Finally, you choose the soil that cultivates the healthiest plants and continues to use it.
If you want to use different kinds of potting soil in one container, you should blend them thoroughly to ensure your plants grow at the same condition.
Avoid common mistakes
You should always be aware of the fact that the quality of the potting soil is not measured by weight. Sometimes, the best potting soil could be somewhat light or seem not water logged.
Best potting soil might not help if you forget to replace it periodically, especially if your plants struggle to grow.
