Zinnia care: These are the requirements for the colorful permanent bloomers

The water requirement

In order for the zinnias to thrive, it is important to water the sun worshipers regularly. This is particularly important in planters, as the limited water supply is quickly exhausted on hot days. It may then be necessary to water beds and pots even twice a day. It should always be poured in the morning and evening hours so that the dreaded magnifying glass effect does not occur. Drops that land on the leaves do not evaporate immediately, so the sunlight breaks in them and burns the leaf surface.

Fertilize regularly

The abundant flowering plants need a lot of strength to form new flowers. Therefore, provide plants in the bed with compost or long-term fertilizer for flowering plants. Zinnias in planters give you a special liquid fertilizer every week.

Zinnias repositioning

Since zinnias are very sensitive to frost, they only thrive as an annual in our latitudes. When the first night frosts herald winter in autumn, the blossoms are over and the zinnia is dug up like all annual perennials.

If you would like to prefer zinnias for the next gardening year yourself, it is therefore advisable not to cut off everything that has faded by the middle of September so that the zinnia forms seeds. In the following year, you can sow them in seed pots (€ 14.90 at Amazon *) or directly in the bed and thus provide for offspring.

Cutting zinnias

A general pruning is rarely necessary. However, it is important to regularly clean everything that has withered. This maintenance measure rewards the zinnia with a rich flower pile.

Zinnia in winter

You can overwinter particularly beautiful zinnias indoors. Dig up the plants before the first night frosts, put them in conventional potting soil and bring the zinnias into the house. A bright, frost-free room, for example the garage or stairwell, is ideal for wintering. It is watered very sparingly and you should refrain from fertilizing completely. From mid-May, the sun worshipers will be allowed to move outside again.

Bugs and diseases

Zinnias are very robust and are rarely affected by diseases and pests. Occasionally the plant becomes infected with powdery mildew. During warm, dry summers, leaf bugs like to feast on the sap of the zinnias. The insects can be easily collected in the early morning hours or controlled by spraying with field horsetail.

Tips

Zinnias magically attract bees, bumblebees and butterflies. That is why planting the zinnia is also very valuable ecologically.
