Planting, sowing zinnia
Whether in a flower bed in your garden or to decorate a pot or garden box, zinnia is to be sown in spring, actually starting indoors if the climate is too cold to start it.
The zinnia flower fears the cold and must be sown in a sheltered place if temperatures don’t yet exceed 65°F (18°C).
- Sowing is performed in March in a greenhouse where the temperature is at least 60°F (15°C).
- It’s possible to plant the seed directly in the ground starting from the month of May.
- Transfer your seedlings to the ground starting in May, ensuring about 8 to 12 inches (20 to 30 cm) space between specimens.
It’s perfectly possible for you to collect Zinnia seeds from wilted flowers and store them over the winter in a paper envelope kept away from moisture. That way you can sow them in the following year.
After having prepared your seedlings in nursery pots, or if ever you’ve purchased ready-grown zinnia plants in a horticulture store, wait for mid-May before transplanting them to the ground.
- Zinnia loves full sun and deserves the warmest spot of your garden.
- Mix garden soil with special flower plant soil mix.
- Add mature compost, manure, or seaweed fertilizer in the hole.
- Space each zinnia 8 to 12 inches (20 to 40 cm) from the next, depending on the variety.
- Water abundantly.
Caring for zinnia
Zinnia is very easy to care for, but a few rules are applicable to maximize its beautiful blooming.
Zinnia will die if it freezes and must be pulled out and thrown to the compost after the first frost spells.
Before that, though, shake the seeds off the plants to let them fall to the ground, and cover them with a layer of dead leaves. It’s more than probable that they’ll self-sow every year.
- Regular watering in case of high temperatures or prolonged dry spells.
- Water in the evening, without sprinkling the foliage to avoid powdery mildew for instance.
- Adding flower plant fertilizer as the plant grows will help extend the blooming and produce amazing flowers.
- It’s possible to remove wilted flowers regularly (deadheading) in order to boost flower-bearing.
