Zinnia hur tätt
Zinnias are sensitive to frost, so do not seed until the last frost has passed in your area. See your local frost dates. Zinnias will grow in a minimum daytime temperature of about 60°F (16°C), though a range of 74–84°F (23–28°C) is preferred. Sow a round of seeds every week or so for several weeks to extend the flowering period. Zinnias are one of the easiest cut flowers to grow. They are the perfect first crop for beginning gardeners and are reliable, prolific producers no matter where you garden.
In addition to churning out buckets and buckets of beautiful, long-stemmed blooms that are perfect for cutting, they are well-loved by pollinators. Zinnias resent cold weather and prefer to be planted after things have warmed up a bit. Many gardeners in warmer parts of the world are able to successfully direct-seed zinnias straight into the garden, but here in cool Washington we start our plants early in the greenhouse, 4 to 6 weeks before our last spring frost.
Plants are then tucked into the field once the weather has sufficiently warmed and all danger of frost has passed. Like every flower grown on our farm, we try to give them the best start possible and prepare our planting beds with a generous dose of compost and organic fertilizer. Learn more about soil preparation here. Once planting beds are prepared, we lay down drip irrigation lines and then cover the beds with a layer of preburned landscape fabric.

Using fabric is not necessary for success, but here on the farm, we use it to increase heat and suppress weeds. Plants are spaced 9 to 12 in 23 to 30 cm apart and watered deeply one to two times per week depending on the weather. If given good soil and a steady supply of water, plants can get huge and will require some type of support. If grown in long rows, plants can be corralled by pounding heavy stakes or T-posts around the perimeter of the bed and using bailing twine to create a string-lined box to hold the plants upright.
The secret to getting the most abundant flower production and longest stems from your zinnias is pinching them when they are young. When plants are 8 to 12 in 20 to 30 cm tall, take sharp pruners and snip the top 3 to 4 in 7 to 10 cm off the plant, just above a set of leaves. This signals the plant to send up multiple stems from below where the cut was made. During spells of hot, dry weather, zinnias are prone to powdery mildew.
If the stem is droopy or bends, it is not ready to cut. If the stem is stiff and remains erect, it is ready to harvest.
