- Temperature and moisture regulation to protect roots
- Weed preventative
- Provide nutrients as mulch breaks down
Even in growing in containers, providing a mulch to the top of your containers can make happy plants. We add bark chips to the top of every container we grow. This helps keep the plants cool in the summer and warm in the winter. It also slows down evaporation in the summer so we don’t have to water as much. It also acts as a weed deterrent so chemical weed control is minimal if at all.
Appropriate mulches should be 3-5″ thick, organic and replenished as needed. Pinestraw, Bark, and leaves all make ideal mulch protection for you camellia sinensis. Rubber mulch, and rock mulch do not provide any nutritional benefits at all, but they can help with weeds and moisture loss.
