In nature, fallen leaves decompose into the nutrients that are used by your tree to feed itself. In an urban setting, however, we rake up those leaves which leaves trees with no way to engage in natural nutrient recycling.
Deficient soil The Texas Panhandle & South Plains is not an environment that is naturally conducive to tree health. Very few of the trees in our neighborhoods grow naturally in the barren soil of our dessert climate, and therefore, need a little extra help. Most trees grow best in soil with a pH level between 6.5 & 7.5. Our soil however, has a pH of 8+. Fertilization helps balance this highly alkaline soil to be able to support healthy tree growth.
Root growth occurs in the fall Trees have an accelerated level of root growth from September through late October. By adding root stimulator, organic matter, & essential nutrients, we can help repair & augment root growth during this pivotal time in a tree's life cycle. Tree roots take a beating from mowing, increased foot traffic, & over/under-watering in the summer. The fall is their time to repair that damage.
Trees are dormant, not dead Deciduous trees go dormant for the winter, however, they are still very much alive and require adequate moisture & nutrient availability to survive the winter in healthy condition. We think of fall feeds as "dinner" for your trees before they go to sleep for the winter. Though "breakfast" in the spring & "lunch" in the fall are also important, we definitely don't want your tree to go to bed hungry.
