# How to Add Phosphorus to Plants
Humans and animals are not the only living things that benefit from the nutrient phosphorus. Plants require phosphorus to aid them in the process of photosynthesis. Phosphorus also benefits plants by increasing their growth rate, converting solar energy to chemical energy and helping to create starch and sugar. One of the most popular ways to increase the phosphorus levels in your plant's soil is to create a homemade bone meal fertilizer.
Things You'll Need
- Bucket
- 5 pounds compost
- 1/2 cup bone meal
- 1/4 cup Epsom salt
- 2 tablespoons kelp extract
- 2 tablespoons fish meal

-
1
Place 5 pounds of compost in a bucket. If you don't have any compost, you can use aged manure from a horse, chicken or cow.
-
2
Add 1/2 cup of bone meal, 1/4 cup of Epsom salt, 2 tablespoons of kelp extract and 2 tablespoons of fish meal to the compost and combine.
-
3
Work 1 cup of the phosphorus fertilizer into the soil directly surrounding your potted plants. Larger potted plants and outdoor plants require 2 or more cups of the fertilizer, depending on their size.
-
4
Water the soil around the plant so that it is moist, but not soaked. This gets the phosphorus deeper into the soil where the roots can draw it up.
-
5
Repeat once per month during the plant's growing season.
