During the cold season, the insulating coconut mulch discs protect your plants from frost and moisture. The densely needle-punched coconut felt inhibits weed growth, keeps the soil moist for longer, and effectively protects against frost damage to plants and pots. Simply place a mulch disc under the pot or on the soil. The mulch discs are available in diameters of 15 cm, 20 cm, 25 cm, 30 cm, 35 cm, 40 cm, and 60 cm. The 40 cm mulch discs are extra thin, while the other sizes are thicker.
