There are around 25 different species of Cosmea, the majority of which are native to Mexico and further south. The annual Cosmea bipinnatus, the common cosmos or Mexican aster, is primarily planted as a garden flower. Why is it if it doesn't show its pretty ray flowers?
What's the reason if the cosmea doesn't bloom?
If the cosmea does not bloom, it is often in soilthat is too nutrient-richThe summer flower prefers permeable, lean soil and a sunny location. In addition, cosms should be watered well in dry weather. Remove dead flowers to encourage further flowering.
Why doesn't cosmea bloom?
There are three possibleReasons why the cosmea does not bloom:
- tonutrient-rich soil
- tolush fertilization
- wrong location
It is often advised to provide cosmos with compost and horn shavings when planting. You should at least avoid the horn shavings as they contain too much nitrogen. Nitrogen, in turn, stimulates shoot and leaf growth. However, for abundant flowering, plants need less nitrogen and more phosphorus. However, mulching the soil with mature compost makes sense. You should also avoid fertilizing with mineral fertilizers.
What can you do to make the cosmea bloom?
If the cosmea does not bloom, you should first investigate the cause and then eliminate the reasons for the lack of bloom.
How do you know the cause of the missing flower?
Do your cosmos grow vigorously and produce tall shoots and lots of leaves? Then the soil is too rich or you fertilize too much. Now you can either thin the soil - for example with sand - or stop thefertilization completely.
What to do if the cause is not too rich soil?
Do the cosmos not only not produce flowers, but also grow puny or look somehow sick? Then they are in the wrong location and have to be transplanted. Find asunny, warm place for the flowerswith poor, preferablysandy soil In this case, flowering will probably start late.
When does cosmea bloom?
Sometimes, however, it's not the cosmea's fault when it doesn't bloom - it's your impatience. The decorative basket, as the summer flower is also called because of its pretty basket flowers, usually bloomsonly from July onwards In damp and cool weather, the flowering can start a little later because the exotic plant is warm and a lot loves sun. But it often delights us with its colorful flowers well into October.
Tip
Should you cut off dead flowers?
Most Cosmea species and varieties bloom from July to October, so they keep producing new flowers. To ensure that this splendor is maintained for as long as possible, you should regularly remove dead shoots. Otherwise, the plant will invest its energy in producing seeds and develop fewer and fewer flowers.
