Q.Fertilizer
When would be the best time to put cow manure on my new perennial flower bed? in the fall after planting or in spring before they start to grow?
When it comes to fertilizing, more does not mean better. It is possible to overfeed your plants. Too much fertilizer can damage and maybe even kill your plants. Before applying any fertilizer, it’s a good idea to have your soil tested so you can select the type and formula that suits your plants’ needs. In return, our plants will reward us with bigger flowers, bigger leaves, and bigger fruits and vegetables.
