5 natural fertilizers to fertilize plants

When Should You Fertilize?

To achieve beautiful, thriving flowers, proper care during the growing season is essential. This period typically runs from March to October, when flowering plants require regular fertilization. Apply a soluble fertilizer monthly for fast-growing plants, and every two months for others. If you’ve just purchased or repotted a flowering plant, wait a month before starting to fertilize.

During the dormant period, avoid fertilizing indoor plants as their needs decrease.

The Importance of Fertilizers

Fertilizers provide essential nutrients for healthy plant growth, including:

  • Nitrogen: Promotes foliage development; a deficiency causes yellowing leaves.
  • Phosphorus: Stimulates root growth and flowering; deficiency results in dark or red foliage and slow blooms.
  • Potassium: Enhances nutrient uptake and improves disease resistance.
