Propagate Dietes grandiflora from seed or by division. The best time to sow and divide the Dietes grandiflora is in spring.
When propagating by seed
Dietes grandiflora can be sown directly into the soil in the spring, but can take many years to germinate.
When propagating by division
Water the plants you want to divide the day before to help loosen the plant roots.
Use a pitchfork to lift a large clump, and divide the clump using a spade.
Dig a hole twice as wide as the plant roots to help the roots spread. Ensure that you prepare the hole with a high-quality compost.
After planting, water the plant thoroughly to remove any air pockets and keep the soil moist until the plant is established.
