Hollyhock Chaters Double Mixed

When to Sow Chaters Double Mixed Hollyhock Seeds

January to March or July to September

Where to Sow

Sow seed on the surface of the compost and cover with a very fine sprinkling of vermiculite or finely sieved compost. Place in a propagator or in warm place at around 15-20°C (59-68°F) until the seeds germinate.

What to do Next

When the seedlings are large enough to handle, transplant each seedling into the individual pots or a multi-cell tray. Plant out spring raised plants into a sunny border 45cm (18") apart. Late summer/ autumn raised plants can be overwintered in a cold frame and planted out the following spring.

Maturity

July to September (the following year for later sowings)

Height

180cm (6') plus

Handy Tip

Glasshouse sowings will flower the same year. After flowering, cut back the plants to improve the second year's growth.
