A: No, perlite is a lightweight volcanic glass used for aeration, while horticultural grit consists of crushed stones for drainage. They serve different primary functions in soil mixes.

Q: Should I use horticultural grit or perlite for succulents?

A: Both work, but perlite improves aeration in potting mixes, while horticultural grit adds weight and stability. Succulents often benefit from a blend of both.

Q: Can perlite replace horticultural grit in soil mixes?

A: Partially—perlite enhances drainage and airflow, but horticultural grit provides lasting structure. Use perlite where lightness is preferred, grit for heavy-duty drainage.

Q: What are the pros of perlite vs. horticultural grit?

A: Perlite is lightweight, sterile, and retains moisture, while horticultural grit offers durability and prevents soil compaction. Choose based on plant needs.

Q: Why mix perlite and horticultural grit together?

A: Combining both balances aeration, drainage, and soil structure. This mix suits plants like cacti or orchids needing fast-draining yet stable mediums.

Q: Do perlite and horticultural grit affect soil pH differently?

A: Perlite is pH-neutral, while some horticultural grits (e.g., limestone-based) may raise soil alkalinity. Test grit composition if pH sensitivity is a concern.

Q: Which is better for heavy clay soil: perlite or horticultural grit?

A: Horticultural grit is ideal for breaking up clay and improving drainage long-term. Perlite works but may crush over time in dense soils.
