Where to grow Upright Water Milfoil

Soil & planting

Watering & feeding
Upright Water Milfoil is adapted to wet or boggy ground. As an Australian native, feed it only with a low-phosphorus native fertiliser. For the first year, favour occasional deep watering over frequent shallow drinks so roots move into the surrounding soil.

Using Upright Water Milfoil in the garden

Companion planting & design
For easier irrigation and care, group Upright Water Milfoil with species that also favour wet or boggy ground and subtropical climate. Leave enough room for the mature spread so neighbouring plants are not crowded out. It combines naturally with other Australian natives in a habitat or water-wise garden.
