Fertilizing garden flowers in spring and summer
Garden plants growing in the open field need regular feeding. Over time, the supply of nutrients in the soil is depleted, and the flowers begin to "starve", which negatively affects their appearance. Timely application of fertilizers will not only provide them with the necessary microelements for active development, but will also help to quickly adapt after the winter period.
Top dressing of garden flowers must be carried out with the onset of spring, as well as support the plants during the summer. The frequency of fertilization depends on which species the crops belong to (annuals or perennials).
Preparations in granular form are used for spring top dressing by direct embedding into the soil. For the summer period, liquid forms used for root and foliar feeding are more suitable.

Features of fertilizing annual garden flowers
Plants that are planted for one season, it is enough to feed only 2 times:
- in spring (2 weeks after planting);
- in late spring - early summer (when buds are being laid).
Do not fertilize flowers that have just been planted in the flower bed - you need to give them time to adapt. In addition, top dressing must be applied to completely healthy plants.
During the first feeding, it is necessary to provide the plantations with nitrogen using organic fertilizers. During the growing season, flowers need phosphorus fertilizers.
Features of the use of fertilizers for perennials
Perennial garden flowers and shrubs need to be fed at least 3 times:
- the first top dressing is in early spring, when the earth dries up slightly (nitrogen fertilizers);
- the second feeding - during the period of bud formation, May-June (phosphorus preparations);
- the third feeding - after the end of flowering, August (potash fertilizers for laying buds for the next season).
You cannot fertilize garden flowers in early spring, when there is still snow on the flower bed, and during dormancy.
Nitrogen fertilizers for garden flowers
Nitrogen fertilizers have proven themselves well:
- Manure-based infusion.
- Wood ash mortar.
- Ammonium nitrate.
- Urea.
Phosphate fertilizers for garden flowers
For feeding during the flowering period, you can use both single-component phosphorus preparations, and complex ones:
- Superphosphate.
- Stimulator Energen.
- Agricola for flowering plants.
- Agricola for ornamental plants.
- Bud preparation (for spraying).
Potash fertilizers for garden flowers
To replenish potassium reserves, which ensures the laying of flower buds for the next year and prepares the plants for a good winter, use:
- Potassium chloride.
- Potassium sulfate.
- Potassium nitrate.
- Kalimagnesia.
