Fertilize this plant in the early spring before new growth appears and again in mid-summer if desired.
Pruning Carex Mohriana Mackenzie
Pruning is usually not required for Carex Mohriana Mackenzie if it is grown in optimal conditions and receives enough water and nutrients. However, removing dead or damaged leaves is essential to keep the plant healthy. If you want to control plant size or maintain its shape, you can prune it back in early spring before new growth appears.
Propagation of Carex mohriana Mackenzie
Carex mohriana Mackenzie, commonly known as Mohr's sedge, is a perennial grass-like plant that can be propagated by various methods. The plant produces rhizomes and seeds, which are the primary means of propagation.
Propagation by rhizomes
Rhizomes are underground stems that grow horizontally and produce new shoots and roots. To propagate Carex mohriana using rhizomes, follow these steps:
- Carefully dig up the plant during the dormant season (fall or winter).
- Break apart the rhizomes into small sections with at least one shoot and some roots attached.
- Plant the rhizome sections in well-draining soil, about 1 inch deep.
- Water the newly planted sections thoroughly.
- Keep the soil slightly moist and provide shade until new growth appears.
Propagation by seed
Seeds can also be used to propagate Carex mohriana. The plant produces small, light brown seeds enclosed in capsules that ripen in early summer. Here's how to propagate using Carex mohriana seeds:
- Collect the ripe seeds by cutting the seedheads and storing them in a paper bag until they are completely dry.
- Sow the seeds in a mixture of sand and peat moss, covering them with a light layer of the mixture.
- Water the seeds gently and keep the soil moist, but not waterlogged.
- Place the seeds in bright but indirect light and at a temperature around 70°F (21°C).
- Germination will occur in 3-4 weeks and the seedlings can be transplanted once they have developed a few leaves.
Propagation by rhizomes and seeds can both be successful in producing new plants of Carex mohriana. It is important to note that this plant prefers moist, shaded areas with well-draining soil and protection from direct sunlight and high temperatures.
