Fertilizing Spider Plant

Plants absorb nutrients through their roots, and houseplants depend on rich potting soil and fertilizer to get the nutrition they need. As the plant depletes the nutrients in the pot soil, fertilization becomes more necessary to support growth. Regularly using proper plant food will support growth and help spider plants become full and leafy. 


Why Fertilize Spider Plant

Fertilizing spider plants encourages growth. Spider plants are moderate to fast-growing houseplants and require a steady supply of nutrients to support their proliferation. Healthy, well-fed spider plants become large and full, blooming regularly and producing offshoots. Spider plants should be fed when actively growing, but not when they are resting in the winter. Over-fertilized plants will develop brown leaf tips.

How Often To Fertilize Spider Plant

Fertilize spider plants every two to four weeks during the spring and summer when the plant is actively growing. Regular applications of fertilizer support consistent and ongoing growth. Large sporadic doses of plant food can be harmful for spider plant, as indicated by brown leaf tips. 

How To Tell If Spider Plant Needs Fertilizer

Most houseplants benefit from routine fertilization, but small, under-sized spider plants are particularly hungry. Plants in poor-quality potting soil are also good candidates for regular fertilizer applications. A well-balanced supply of nutrients will help the plant grow large and healthy.

Best Fertilizer For Spider Plant

Use a balanced, water-soluble fertilizer to feed spider plants. A plant food with an NPK ratio of 10-10-10 or 15-15-15 is a good choice for spider plants. A water-soluble product will dissolve in water and can easily and safely be absorbed by the roots. Another benefit of water-soluble fertilizers is that feeding and watering can be combined into one step.

Spider Plant Fertilizing Tips

Fertilizing is an essential part of a spider plant care because it supports growth and creates a full and healthy plant. Feed spider plants every two to four weeks during the growing season. Use a balanced, water-soluble fertilizer. Do not feed plants during the winter as growth slows.

  • Use a balanced fertilizer with a ratio of 10-10-10 or something similar.
  • Water-soluble fertilizers can be applied during a routine watering session.
  • Fertilize spider plants every two to four weeks during the growing season.
  • Hold off on fertilizing dormant plants.


-Always wear protective gloves and a face mask when handling chemical fertilizers.

-Closely follow all directions and storage guidelines that are on the fertilizer label.
