The fact that a lot does not necessarily help much also applies to the topic of fertilizing the phlox. The correct composition of the fertilizer is more important than the quantity, otherwise the opposite of what you want to achieve could occur.
If possible, fertilize phlox with organic fertilizers so as not to harm insects
Only when plants are optimally supplied with nutrients and water will they stay healthy and bloom profusely. If they get too much or too little of some substances, then they are prone to diseases and bloom sparsely or not at all. The proximity of other plants also plays an important role. For example, the phlox gets along well with roses, asters or delphiniums.
What you should consider when fertilizing
Phlox can be very sensitive to too much nitrogen in the soil. This makes it susceptible to various diseases and sometimes causes the phlox to flower only sparsely or even not to flower at all. Therefore, pay attention to phosphate-rich and low-nitrogen fertilizers. The phlox prefers organic fertilizers such as compost, horn meal or nettle disease.
While perennial phlox only needs to be fertilized once a year, annual phlox needs fertilizer on a regular basis. In spring, give your perennial phlox a dose of compound fertilizer or mix well-rotted compost into the potting soil. Then spread a layer of mulch (€239.00) on the ground. The new shoots must not be covered. The mulch layer keeps moisture in the soil and prevents too many weeds from growing.
Fertilize your annual phlox regularly, about every two weeks. A liquid fertilizer is particularly suitable for this. If you prune the tops of the main shoots on the young plants, you encourage the plants to flower more profusely.
The essentials in brief:
- best to use compost
- fertilize with low nitrogen
- Fertilize annual phlox regularly
- Fertilize perennial phlox in spring
tips and tricks
For lush flowering, the phlox needs a phosphate-rich fertilizer that contains little nitrogen. This keeps the plants healthy for longer.
