Zinnia Flower

Een van de gemakkelijkste eenjarige te groeien, Zinnia bloemen brengen een explosie van kleur ..

One of the easiest annuals to grow, zinnia flowers bring an explosion of color wherever they go. The show lasts from late spring until the first frost in fall. Butterflies and hummingbirds are attracted to the cheery flowers that bloom in nearly every bright color imaginable. They grow quickly and reliably, making them a great choice for first-time flower growers. Add in their low maintenance requirements and the variety of sizes and shapes, and you can’t lose.

How to plant:

Zinnias are best started from seed and can be sown directly in the garden after the threat of frost has passed. If you’d like to get a jump on them and start earlier indoors, try peat pots or other containers that can be planted directly in the ground, as zinnias can be a bit finicky when transplanted. Sow seeds ¼-inch deep and follow spacing directions on seed package. Give them sunshine and water and you’ll have seedlings popping up in 4 to 7 days. Thin the seedlings to spacing of 6 to 18 inches (depending on variety) by snipping at the soil line with scissors. (Tip: Pulling out seedlings can disturb the roots of those left behind.) Zinnias grow quickly and you’ll have beautiful bright blooms in about 60 days.

CARE

Pruning:

For taller varieties that you’d like to use for cut flowers, Floret Flower Farms recommends snipping out the center flower when the plants are about 18 inches tall, and although it “feels pretty counterintuitive at the time, it will encourage plants to begin branching low and ultimately produce much longer stems.” Spent blooms should be deadheaded to encourage and prolong further flowering.

Soil:

While zinnias aren’t particularly picky about their soil, they do prefer it to be fertile, humus-rich, well-drained and with a pH of 5.5 to 7.5.

Amendments & Fertilizer:

Add compost to the area where zinnias will be planted to enrich the soil. An occasional light dose of a well-balanced fertilizer can be applied, but isn’t always necessary.

Watering:

Water regularly, for a total of about 1 inch per week. Although they can tolerate dry conditions, they will do much better with consistent moisture in the soil. Keep excess moisture away from the foliage by watering at the base of the plant; this will help keep your plant healthy and prevent disease.

Propagation:

Seeds are easy to save by letting the flowers dry completely on the stem. Remove seeds by lightly crushing the dried seed head. Store the seeds in a cool, dry place for planting next spring. Keep in mind, however, that seeds saved from hybrid plants may not develop true to the parent plant.

Diseases and Pests:

Bacterial and fungal spots, powdery mildew and bacterial wilt can all be troublesome for zinnias. Keeping the foliage dry and providing good air circulation will go a long way toward prevention. Zinnias can also be host to caterpillars, mealybugs and spider mites. It’s best to remove caterpillars by hand, but mealybugs and spider mites can be treated with insecticidal soap. Try cultivars from the Profusion series for increased resistance to powdery mildew.

Other:

Zinnias are deer resistant and may even help protect other plants located next to them.
