They shine in the most beautiful colors: Chrysanthemums enrich our garden and balcony in yellow, pink, copper, white, and many other colors. However, sometimes they don’t bloom at all. They then just look like green herbs in a pot or bed. But it doesn’t have to be that way.

If chrysanthemums don’t want to bloom but otherwise grow splendidly, there can be several reasons. First, you should check the period in which your plant is supposed to bloom. Depending on the variety, the blooming period can vary. If the timing is right and the chrysanthemum still doesn’t bloom, you should investigate the cause. myHOEMBOOK reveals the three most common reasons.

1. Incorrect Watering

If the chrysanthemums simply won’t bloom, it might be because they were watered incorrectly. Generally, they don’t need an excessive amount of water, but not too little either. The root should neither dry out nor stand in water. When the top layer of soil has dried out, the next watering can take place.

But that’s not the only point to consider when watering. It’s important not to water chrysanthemums over the bloom. If the bloom gets wet, you increase the risk of powdery mildew.

2. Incorrect Location

Chrysanthemums are generally quite easy to care for, but if they’re in the wrong spot and don’t feel comfortable, they won’t bloom either. When it comes to location, chrysanthemums are particular. It should be bright but not full sun, moist but not wet. It’s best to place your plant in a bright spot without direct sunlight. They especially don’t tolerate the intense midday sun well. The soil should be humus-rich and loose.

3. Chrysanthemums Need Regular Fertilization

Chrysanthemums are heavy feeders. This means they need a lot of nutrients to bloom in full splendor. Regular nutrient supply is especially important when the plants are in pots. About every two weeks, you should give them some liquid fertilizer. A sign of nutrient deficiency is when the plant forms buds but drops them before blooming. It simply lacks the strength to let the bloom open.
