How to Grow Rhodohypoxis

It is best to grow Rhodohypoxis from tubers. This is because Rhodohypoxis plants grown from seed may not be as pretty (not stay true).

The tubers should be sown about 3 to 5 cm (1 to 1.5 inches) deep, and at 6 to 8 cm (2 to 3 inches) apart. Plant the tubers at the start of spring (before the last frost).

If you do plan to grow Rhodohypoxis plants from seed, then simply cover them with soil. It should take from one to three months for Rhodohypoxis seeds to germinate.

Rhodohypoxis prefers to grow in a sunny area of the garden. This should have a well drained, lime-free, soil.

Caring for Rhodohypoxis

Rhodohypoxis takes a little bit of looking after. They should be lightly fertilised now and again. The soil watered frequently to keep moist in the growing season.

Do not water Rhodohypoxis in the winter.

If you require more Rhodohypoxisplants, then propagate them by division of offsets in the springtime.
