Potting soil is made up of various nutrients that keep plants healthy and help them grow.

Buyer’s Guide

From ingredients to amount, there are several elements that separate different varieties of potting soil from each other. Before you choose a mix for your plants, consider the following factors.

Plant

Some soils work for a wide range of plants, but many are formulated for specific plants, such as succulents, orchids, houseplants, and vegetables. While using an all-purpose mix may be sufficient if you have a lot of plants around your home, finding a dedicated mix gives your plants the best chance to grow healthy.

Location

In addition to the species of plant, many potting soil mixes are designed for either indoor or outdoor use. Outdoor soil is heavier and coarser than indoor soil, so it can retain more moisture in the sun and resist harsh weather conditions.

Ingredients

Most potting soil mixes contain peat moss, perlite, or both. Peat moss is absorbent and resistant to decay, while perlite has an open structure that allows water and air to circulate freely for drainage.

Beyond peat moss and perlite, make note of the other ingredients to see if they’re right for your specific plant. For example, if you’re planting seeds, don’t use a mix with large rocks or twigs that could limit growth.

Moisture Control

The ingredients used to make soil determine how well it retains moisture. For example, peat moss absorbs around 30 times its weight in water, while coconut coir absorbs around nine times its weight. Carefully read a soil’s description to see how well it retains moisture as well as how it eliminates excess moisture.

Amount

To avoid buying too much or too little soil, calculate how much you need for all of the plants in your garden. You can measure the square footage of outdoor areas or count the number of indoor or outdoor pots. Purchase one or more bags to properly fill these spaces.

The Best Plants For Amateur Gardeners

Some plants are trickier to take care of than others. While even beginner gardeners know that food, soil, sunlight, and water are needed to help keep plants alive, some require additional maintenance and care.
