Bill: Keep soil mixes light and quick draining. Make sure your soils are
dry and sifted. Go easy on organic content for most trees. You can add
nutrients in controlled amounts later by fertilizing.
Vaughn Banting has made the following recommendations for soil
mixes. "For deciduous material and most broadleaf evergreens use a
completely dry mix composed of roughly one part leaf mold, peat moss or
other decomposed organic material to three parts coarse soil, fine aquarium
gravel or a baked clay particle such as 'hadite' along with two parts garden
loam or unimproved potting soil.
All soil mixes need to be very dry, so that they can be worked in
between the exposed roots and rootball of your tree. Dry soil worked in
well with a chop stick or a pencil will eliminate dangerous air pockets.
For azaleas follow the above mix but increase the peat moss to four
or five parts. Use only peat for the organic part of the mix as the slight
acid reaction it provides is just what azaleas require.
If you plan to pot junipers, pines, cedrus, or other needle
evergreens, use a mix of roughly one part organic material that has a
minimal acid reaction, such as 'black cow' manure or leaf mold to five or
six parts coarse sand or fine gravel with two or three parts garden soil."
These are not the only successful soil recipes, but they will ensure a well
drained soil.
