Q. How do I care for trees? I need to transplant some small bare-root ones, and I want to properly feed the other trees in my yard.
A. If you are transplanting small trees, you need to do the following: Dig a hole 12″-15″ (30-37.5 cm) wide and deep. Make a Pre-Plant mix with 5# (2 kg) lime with 4 ounces (114 grams) Epsom Salts and 1 ounce (28.5 grams) of borax. Make a “Weekly Feed” mix with 25# of 16-16-16 (11.36 kg) fertilizer plus 4# (1.8 kg) of Epsom salts and 10 ounces (285 grams) of the Mittleider Micro-nutrients.
Mix 2 ounces (57 grams) Pre-Plant mix and 1 ounces (28.5 grams) with the soil going in the hole. Plant the tree. Water regularly. Wait 3 weeks, until the roots are settled and well established in the soil, then apply 1 ounce (28 grams) Weekly Feed to the soil around the tree, keeping at least 3″ (8 cm) away from the trunk. Apply Weekly Feed again in 45 days, and again in 45 days, watering thoroughly each time. In long growing seasons an additional feeding can be made.
For established small trees, loosen the soil at the surface and apply Pre-Plant mix at the end of the dormant season. Trees should receive Pre-Plant once each year, in amounts double the Weekly Feed applications which follow. Two weeks after applying the Pre-Plant, apply Weekly feed as follows: For a 1″ to 2″ (2 1/2-5 cm) diameter trunk – 1 ounce (28.5 grams). A 2″ to 4″ (5-10 cm) diameter trunk gets 4 ounces (114 grams). And a 4″ to 8″ (10-20 cm) diameter trunk should receive 8-12 ounces (228-342 grams). After 45 days and 90 days, and in long growing season areas – when next year’s buds begin to form – repeat the above applications. Large trees of 12″ to 16″ (40-80 cm) diameter, would get 1-2# (454-908 grams) in 4 applications.
