What to Use to Fill Big Planting Pots

Planting pots come in various sizes depending on the size of the plants you are hoping to grow. Big planting pots require a substantial amount of soil to fill them. However, it's not just any soil that can fill big planting pots. The right soil composition and other materials need to be factored in. This article hopes to enlighten you on what to use to fill big planting pots.

1. Potting Soil

Potting soil is a common soil type used in planting pots. It is a lightweight and porous soil that drains well and allows air and moisture to reach the roots. Potting soil is made of peat moss, perlite, and vermiculite, which are natural materials that promote healthy plant growth.

Big planting pots require more potting soil and should not be entirely filled with it. Potting soil can be mixed with other materials to increase its volume and distribute moisture evenly.

2. Perlite

Perlite is a volcanic glass that is processed into light, white, and porous granules. It is widely used in potting soil mixes because of its ability to improve drainage and aeration. Perlite absorbs moisture and releases it slowly back to the plant roots, ensuring that they are well hydrated.

Perlite is particularly helpful in filling big planting pots because it is lightweight, which helps to reduce the overall weight of the pot. Perlite can be mixed with potting soil or any other soil type you wish to use in your planting pot to make it more porous and improve drainage.

3. Vermiculite

Vermiculite is another soil amendment that can be used to fill big planting pots. Vermiculite is a natural mineral that is processed into lightweight pebbles. Just like perlite, vermiculite improves drainage, aeration, and helps with moisture retention. Vermiculite absorbs excess water and nutrients, making them available to the plant roots as needed.

Vermiculite can be mixed with potting soil or any other soil type in any proportion to fill big planting pots. Vermiculite can also help reduce the overall weight of the pot, making it easier to move around when needed.

4. Compost

Compost is a rich and organic matter that is produced after decomposing organic waste matter like kitchen scraps, leaves, and twigs. Compost is nutrient-rich and contains micro and macro-nutrients that plants need to grow healthy. Compost can be mixed with any type of soil to improve its fertility and texture.

Compost is particularly beneficial in filling big planting pots because it helps retain moisture and nutrients, reduces soil compaction, and enhances drainage. Compost can be mixed with potting soil, vermiculite, perlite, or any other soil type you wish to use, but it should not be more than 25% of the soil mix.

5. Sand

Sand is an essential material that can be used to fill big planting pots. Sand improves drainage, aeration, and helps prevent soil compaction. Sand should only be used as a soil amendment and not as the primary soil mix. Sand is not nutrient-rich and does not hold moisture, making it unsuitable for growing plants alone.

Sand can be mixed with potting soil, vermiculite, perlite, or any other soil type in any proportion to fill big planting pots. It is essential to keep in mind that too much sand can make the soil mix too heavy and reduce its water retention ability.

Conclusion

Big planting pots require a substantial amount of soil to fill them, and filling them with the right soil composition is essential for healthy plant growth. This article has provided essential material options that can be used to fill big planting pots, such as potting soil, perlite, vermiculite, compost, and sand. By mixing these soil amendments in the right proportion, you can create the perfect soil mix for your big planting pot and help your plants grow healthy and strong.
