Before planting, it is good to add mature compost or well-rotted manure to enrich the substrate, promoting flowering and healthy plant growth.
How to plant and multiply freesias
- Planting time: Plant bulbs in the fall so they bloom in the spring. In mild climates, this can also be done in late winter.
- Preparation: The bulbs should be firm. If they're soft, discard them. Soaking them in warm water for a few hours helps hydrate them.
