Ahimsa Organics Neem Cake is an excellent organic fertilizer that enriches soil by slowly releasing nitrogen, aerating the soil and improving the overall soil quality. It is made from the residue obtained from neem seed kernels, which have been crushed to extract the oil. Neem Cake also protects plants by promoting plant growth and disease resistance, and its use can help increase earthworm populations. Apply before or during planting or around the root zone for established plants.
