1. Planting

Generally sown in spring from March to April. They can be sown in a seedbed or sown directly in a courtyard flower bed. The seedlings grow quickly, so thinning should be done in time. After one transplanting, they are planted out in the garden in early June. If sowing is delayed, the seedlings can be potted and can bloom around National Day.

2. Light and temperature

It likes light and also tolerates shade, and needs at least 4 hours of diffused sunlight per day.

If there is a lot of rain, attention should be paid to drainage and flood prevention, otherwise the roots and stems are prone to rot. After planting out, fertilize frequently, and especially take care not to let the soil alternate between dry and wet. In summer, never water wilted plants under the blazing sun. Especially during the flowering period, they must not suffer drought, otherwise the flowers are prone to drop.

4. Flowering period control

If you want to delay the flowering period, you can sow in early July. You can also use the method of pinching, while removing early-opening flowers and flower buds, so that the plant keeps growing larger. Apply fertilizer once every 15-20 days. After September, more flower buds will form, so that they bloom around National Day.
