When using Fertilome Tree and Shrub you should treat mid-fall and again in the spring with a a soil drench. You may need to moisten the ground prior to the treatment, use the higher volume of water as recommended on the label and keep the soil moist for the following 14 days after the treatment to encourage the tree to trans-locate the product.
