When do dahlias bloom?
Sharing with everyone the content about when dahlias bloom and a brief introduction to the blooming period of dahlias in the field of green plants and flowers, let's get to know more about it together.
Dahlias have large and beautiful blooms with vibrant colors and an extremely long blooming period, lasting from June to December, making them very popular and suitable for display on balconies and courtyards at home.
Dahlias generally start blooming in late June and reach full bloom in September. During this period, with proper care, the plants will produce more and larger flowers with even brighter colors. So, what issues should be considered when caring for dahlias in autumn?
1. Semi-shaded environment care
Dahlias prefer a semi-shaded environment and are susceptible to strong sunlight. However, they cannot thrive without sunlight for an extended period. Prolonged lack of sunlight can lead to the branches and leaves growing excessively, consuming a lot of nutrients, and the plants will not form buds or bloom.
In summer, when caring for dahlias, it is important to provide shade to prevent the branches and leaves from wilting due to sunburn. In autumn, the sunlight during noon is still relatively strong, and it's not suitable for direct sunlight. It's best to place the potted plants in a location with weak scattered light. Only in a semi-shaded environment can the plants grow vigorously and bloom more.
2. Overly wet soil can cause root rot
Although dahlias are root tuberous flowers, they are not drought-tolerant and fear waterlogging. When the potting soil is too dry, the branches and leaves will wilt, affecting the growth of the plant. When the soil is too moist or waterlogged for an extended period, the root tubers can easily rot, causing the entire plant to wither.
When watering dahlias in autumn, wait until the surface of the potting soil is dry before watering, or keep the soil slightly moist. This ensures sufficient water while avoiding waterlogging, allowing the plants to grow healthily.
3. Supplementing nutrients to promote blooming
Many dahlias do not receive much fertilizer, resulting in weak growth and smaller blooms. This is due to insufficient nutrients. Dahlias have large flowers and a long blooming period, so they require a lot of nutrients and should be fertilized regularly.
When planting dahlia root tubers in spring, it is advisable to use more nutrient-rich humus soil or add some decomposed organic fertilizer to the soil to increase its fertility, which helps the new buds grow stronger.
During the period of growth of branches and leaves, watering with a dilute solution of nitrogen, phosphorus, and potassium fertilizer every half a month can make the plants grow lush. After entering autumn, applying phosphorus and potassium fertilizers can promote the plants to form a large number of flower buds.
4. Pruning the withered flowers
When withered flowers appear, they should be cut off promptly. Allowing them to wither naturally not only wastes nutrients but also affects the opening of other buds.
Regularly pruning the withered branches and leaves, as well as thinning out some overly dense foliage to increase light penetration, is more beneficial for the plants to bloom.
If you care for dahlias at home and they enter the full bloom period in autumn, following the above points will ensure the plants bloom abundantly and continue until the frost season.
The comprehensive explanation provided above about when dahlias bloom and the introduction to their blooming period, I hope it can act as a brick to attract jade and solve your problems with green plants.
