Zoysia Grass Fundamentals
Three species matter: Z. japonica (coarse texture, cold-hardy, seedable), Z. matrella (fine texture, sod/plugs only), and Z. tenuifolia (finest, ornamental use). All spread via BOTH stolons and rhizomes, producing denser turf than bermuda. Roots reach up to 36 inches deep (most lawns 8-16 inches). Ideal growing temperature is 85-90°F. Zoysia goes dormant when soil temps drop below 50°F — lower threshold than bermuda, so it stays green longer in fall. Requires 6-8+ hours of sun but tolerates partial shade far better than bermuda. DO NOT seed Z. matrella varieties — they are sod/plug only.
Frequently Asked Questions
What are the three zoysia species?
Z. japonica is the coarsest and only seedable type. Z. matrella has finer blades and is sod-only. Z. tenuifolia is the finest and mostly ornamental. Most home lawns use japonica or matrella cultivars.
Does zoysia spread on its own?
Yes. Zoysia spreads via both stolons (above ground) and rhizomes (below ground). It fills in slowly — expect 1-2 full seasons for plugs to form a solid stand.
How deep do zoysia roots grow?
Zoysia roots can reach 36 inches in ideal conditions, with most roots in the 8-16 inch range. This gives it solid drought tolerance once established.
