Thalia Care Tips
Established thalia plants require little maintenance when their needs are met.
Soil and Water
Thalia plants prefer damp or wet, organically rich loam or clay soil.
Drainage is not a concern, as the plants are unbothered by frequent standing water.
Temperature and Humidity
Thalia is cold-hardy in USDA Zones 6-11.
If it is growing in wet soil pond-side, add a thick layer of mulch.
In colder areas, move the plant to a greenhouse to protect it from the cold.
However, it is critically important not to allow fertilizer into ponds or streams.
Pruning
Thalia is a herbaceous perennial.
In fall, cut back the foliage to about 6 inches above the water line as winter approaches.
Thalia will regrow when the soil and air temperatures warm in spring.
Potting and Repotting
Use a heavy-duty, wide, shallow container to sink thalia in a pond.
How to Propagate Thalia
Division:The easiest way to propagate thalia plants is bydivision.
Dig up a clump in spring just after shoots emerge.
Use a sharp spade to cut the clump into several sections, making sure each section contains rhizomes.
Replant the sections immediately.
Seeds:If you have existing thalia plants, collect the seeds after the plant’s fruit turns brown.
Shake the clusters to release the seeds.
When the seedlings are 12 inches tall, they can be transplanted.
This aquatic plant is often seen in wetlands, swamps, marshes, or near ponds in the wild.
