Study Notes

Plant Propagation Methods

Lemongrass is propagated by plant dividing, specifically using the offsets, and should be planted in early spring.
The used part of lemongrass is the leaves and stem.

Rosemary Propagation

Rosemary can be grown from seed, but cultivars do not retain their original characteristics, so semi-ripe cuttings are used for propagation.

Calendula Propagation and Care

Seed is the primary method of propagation for the calendula plant.
Calendula requires a moderate amount of water, which is dependent on the type of soil it's planted in.
