Faded Zinnia flowers should also be removed regularly to maintain bloom – unless seeds are to be obtained.<\/div><\/div>\n
The flowers, like many summer flowers, depend on a regular supply of nutrients and should therefore be well fertilized. When fertilizing zinnias in pots or window boxes, it is especially recommended to use a liquid nutrient fertilizer.![\"colorful](\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/colorful-zinnia-flowers-cover.jpg\")

About every two weeks, 0.5 to 0.8 us fl oz is added to 169 oz of watering water and thus simply applied when watering<\/strong>. The nutrients contained reach the roots directly and are quickly absorbed. Acute deficiency symptoms, such as a yellowing of the lowest leaves due to nitrogen deficiency, can also be quickly remedied in this way.<\/p>\n<\/span>Are zinnias hardy?<\/span><\/h3>\nZinnias are not hardy in our area, as they cannot tolerate frost of any kind. As it is usual with annual plants anyway, the flowers die completely after seed ripening, so it cannot be overwintered indoors either. Only in the form of seeds can the plant make it to next year.<\/p>\n
<\/span>Propagating zinnias<\/span><\/h2>\nZinnias can be propagated by their seeds. However, in order for seeds to form, they must not be double flowers, as these are infertile. Flowers visited by bees and other pollinators cross with other varieties of the flowers so that often the seed no longer contains the original variety of the mother plant.![\"zinnia-grow-small-plant\"](\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/zinnia-grow-small-plant.jpeg\")

However, for those for whom varietal purity is not a top priority, they may be able to enjoy gorgeous new color combinations from homegrown seeds. For seed collection, faded flowers must of course be left standing and not pruned. The numerous elongated achene fruits of the zinnia ripen until October and can be cut off together with the flower head in late fall when the inflorescence has dried up and dried indoors for two to three weeks at room temperature.<\/p>\n
Once the seeds trickle out on their own after a bit of rubbing, separate them from flower debris and store them in paper bags in a dry, cool place. Flower seeds can germinate for about four years if stored well.<\/p>\n
<\/span>Common pests of zinnias<\/span><\/h3>\nSlugs love zinnias and can quickly completely kill young plants. Adult plants, on the other hand, are hardly at risk. Slug protection, therefore, makes sense, especially in the first few weeks after planting. In addition, aphids and spider mites can be found on the summer bloomers. Outdoors, however, beneficial insects such as the ladybug quickly limit explosive reproduction. For more tips on aphid control, see our special article.<\/p>\n
<\/span>Are zinnias poisonous?<\/span><\/h3>\nThe flowers are not poisonous per se, but they can cause allergic reactions when the sap comes into contact with the skin. This is due to alkaloids such as nicotine and various terpenes contained within. Therefore, ideally, always wear gloves when pruning plants. The flowers of the zinnia, on the other hand, are edible and also provide a real feast for the eyes as a decoration or ingredient in flower butter.<\/p>\n
