Buying Guide
What size of perlite should I buy?
8-quart bags are common and convenient for many home setups. If you’re starting seeds, repotting several plants, or mixing multiple containers, stacking a couple of 8 qt bags may be efficient. For small collections, a single bag can cover several pots.
What should I mix perlite with?
Perlite is typically mixed with peat or coco coir, compost, or potting soil to improve drainage and aeration. For orchids, orchid bark mixes alongside coarse perlite create ideal airflow. For seed starting, combine with a fine-textured medium to ensure uniform moisture distribution.
Does perlite provide nutrients?
No, most perlite products do not contain nutrients. They improve structure, drainage, and aeration. If the soil needs nutrients, pair perlite with a balanced fertilizer or a soil mix that includes nutrients.
What plants benefit most from perlite?
Houseplants with drainage sensitivity, succulents, cacti, seedling starts, and orchids can benefit significantly. Perlite helps prevent root rot in poorly drained soils and supports robust root systems through better oxygen access.
What are potential downsides?
Excessive perlite can cause overly fast drying in some setups. It’s important to monitor moisture and adjust watering frequency accordingly. Also, perlite is inert and does not add nutrients, so replacements or supplements may be required over time.
How to choose the right product for orchids vs. general plants?
Orchid mixes typically include bark and coarse substrates with perlite to ensure drainage and airflow. For general houseplants, a balanced mix with perlite for aeration works well. If you’re unsure, pick a universal 8 qt perlite product and layer with a standard orchid mix when dealing with orchids specifically.
