How To Plant Zinnia Seed?
Zinnias are hardy annuals so if sowing zinnia seeds outdoors directly into the soil, don't sow too early. Toward the end of spring is a good idea. Indoor sowing is possible but check the variety. They are not keen on root disturbance so if growing inside use modules or root trainer pots.
- Zinnia loves the sun and as they germinate and grow, keep them weed-free and watered. A good slow-release fertiliser will kick them on. Zinnia plants flower from Mid to late summer
- Protect these plants on chilli evenings when they are young, cover them with a cloche or fleece if the temperature sinks over-night
- Deadhead to encourage flowering and they will benefit from a Seaweed foliar feed once a month
- Powdery mildew can be a problem. So pick over the plants if any leaves become grey
Zinnia Seeds Germination
Zinnia seeds should germinate within 10 to 21 days. If sowing outdoors the seeds need to be sown thinly in a sunny position. Once they begin to germinate thin the seedlings until they reach the spacing of between 30 and 38cm apart.
If sowing indoors, sow the seeds into trays in the windowsill or greenhouse. Transplant the seedlings into trays 5cm apart and grow on ready for planting out.
Zinnias are great garden colour and for cut flowers, which they will supply most of the summer supply all summer. They are such happy plants that a small bed or large container, just for these special plants is well in order.
