Watsonia needs only sun and water and amended soil to thrive, multiply and keep producing tall stems as the corms produce 4-6 foot blooms! They make a good back of the border addition and require no special care.

Outdoor Beds

1. Find a location where the soil drains well and amend it with peat moss, compost, ground bark or decomposed manure as needed.
2. Give them full sun.
3. Plant the watsonia corms 4″ deep and 4″-6″ apart. The corms look like fat, flat gladiola bulbs. There may be a small point or even a bit of last year’s stem on the top of the corm that should be placed facing up.
4. After planting, water watsonia well to settle the soil around the bulbs. Corms will root and sprouts will appear in the fall and flowers will bloom in the spring.
5. Watsonia can be cut and will not hurt the plants.
6. Let them die back in the summer.
7. Foliage may be removed after the leaves die back and the corms become dormant.  In the fall they will begin the growth cycle again.
8. As Watsonia will form large clumps over time and may eventually diminish in blooms, they can be dug and separated ar this time.  Replant promptly.

Barrels and Pots

Follow the same directions as above, but be sure to use very large pots or barrels as these grow very tall!
