Medium size fertiliser cup filled with slow-release fertiliser.

The covered design protects your plants from birds and other animals, wind, and other disturbances.
Can help control the amount of fertilizer, properly and thoroughly. and save fertiliser. With many holes in the bottom and side of these cups, make-fertiliser permeates into the soil slowly, which won't burn the plant's roots easily.
Adopt quality PP-plastic material, which can be reused without crumbling. Not easy to be deformed and corrosion-resistant.
