Fall Fertilization

Fall Fertilization

It seems to early to start talking about it, but fall is just around the corner. With fall come preparations for winter, and let’s not forget about helping our landscapes get ready to deal with frost, frigid temperatures, ice and snow. Fertilizing your shrubs, trees and lawn in the fall can aid in recovery from winter’s stress come spring, roots will absorb nutrients necessary for the initial growth period that comes with the thaw. The sub-surface, liquid-injected, fall fertilizer formulation used by SavATree provides trees and shrubs with several advantages for bearing stress from winter; fertilization replenishes vital nutrients necessary for overwintering and healthy spring blooms and it also aerates and relieves compaction, allowing air and water to reach and stimulate root hairs where absorption takes place. Lawns benefit from fertilization in the fall twofold; 1) it helps recover from summer stress brought on by heat, drought, pest and/or disease and 2) it prepares turfgrass to handle stress from winter extremes.

Promoting healthy root growth is the goal of fall fertilization, this will support plants and help them cope with stress throughout the growing season.

The formulation of fall fertilizer, meaning the ratio of nutrients included, differs from that of the spring fertilizer. This fuels the photosynthesis that continues to occur in the bright fall sunlight, but in fall energy is produced and stored for to promote root growth, as opposed to fueling shoot growth and reproduction happening during the summer. This translates into better winter survival rates, lower stress coming out of winter and possible early green up/leaf out without excessive top growth. New root growth literally provides the basis for healthier plants throughout the growing season. Whether for lawn or trees and shrubs, root growth is the primary goal of fall fertilization.

The root system extends beyond the drip line of the tree. A good sub-surface, liquid-injected fertilization will take that into account and make sure fertilizer is applied throughout the root zone.

If you do not already have a fall fertilization in your program, you can ask your arborist to evaluate your landscape to see if one it is necessary or would be beneficial. There are various soil amendments such as mycorrhizae, lime, kelp or others which may be advantageous for your trees, shrubs or lawn, a simple evaluation and/or soil test, performed by your arborist can inform any additional treatments required for the health and vigor of your plants.
