I was asked about adding cow steer manure to the ground over the winter to help build up the
soil. Now is not the time to be adding any kind of fertilizer to your soil if you live in a severe winter climate zone. The addition of the fertilizer will stimulate your plants to begin to grow. During cold weather with shorter daylight hours plants are conserving their energy in order to survive. Stimulating your plants with fertilizer may cause them to die.
I leave leaves and other natural plant matter on the ground in my garden beds over the winter. In the spring I turn them under into the soil with a spade shovel. The natural decomposition of the plant matter helps to add nutrients to the soil. If you have any questions contact me using the form below:
