Perlite is a highly useful component of gardening for many reasons: It is physically stable and retains its shape, even in heavy or saturated soil. It doesn't decompose, so it's ideal for use in potting mixes for plants that are repotted infrequently (such as succulents and other houseplants).

Can I use peat moss instead of perlite?

Perlite and peat moss are both soil amendments used in horticulture to improve soil moisture retention. Perlite has a stronger structure than peat moss. The strong structure allows perlite to aerate soil, by preventing the soil from densely compacting. Peat moss adds to the density of soil.

Should I put anything in the bottom of my planter?

“Skip the gravel inside the bottom of individual or pot liners – It is a myth that a layer of gravel (inside the bottom of an individual pot) beneath the soil improves container drainage. Instead of extra water draining immediately into the gravel, the water “perches” or gathers in the soil just above the gravel.
