Conclusion

Fertilizer is essential for collard greens to grow healthy and strong. The right fertilizer will provide the correct nutrients for the greens, help the greens to absorb water and help to keep the soil loose and aerated.

Greens need a lot of nitrogen to grow, so a good fertilizer for collard greens should be high in nitrogen. A good fertilizer will also contain other nutrients such as phosphorus and potassium, which are important for plant growth.
