Murcott Mandarin Orange Growing Problems

Q. I have several fruit trees planted around my fire pit
near a waterfall and pond.  I bought a
Murcott tangerine which has not grown an inch in 2 ½ years and the tiny fruit
it produces falls off by summer. All the other fruit trees are doing fine
except for this tangerine.

A. This citrus produces fruit ready to harvest from
January through March. It originated from central and southern Florida and does
best in locations where freezing is rare. Any freezing temperatures during the
winter and early spring may cause the fruit to be inedible. I hope it’s planted
in a warm microclimate.
Same Murcott Mandarin orange. 

            Problems
like these, when similar plants are growing together and one does poorly, is
usually a problem with the soil or how it was planted. Possibly irrigation. During
the winter carefully lift the tree from the ground by severing the roots with a
sharp shovel and lifting the rootball with two shovels on opposing sides.
Gently wash the soil from the roots and put the tree in a clean bucket of
water, covering all the roots with fresh water.
            Re-dig
the hole so that it’s five times wider than the tree roots taken from the
ground. If water drainage was a problem, the tree should be planted about a
foot higher than the surrounding soil. Do not use the same soil but replace it
with a soil mix amended for planting.
            When
planting the tree in this hole, the roots should be less than ½ inch below the
finished soil surface surrounding the tree. As soil is added around the roots,
add water from a hose to remove any air pockets. Do not step on the soil with
your feet but use water to settle it around the roots. Remove about one third
of the canopy of the tree after planting. Stake the tree so the lower trunk
doesn’t move for one growing season.

            If
the soil mix was made with a rich compost, no fertilizer is needed for one or
two growing seasons. Otherwise, apply a fertilizer to the soil high in
phosphorus when planting. Next spring place fertilizer 4 inches below the soil
and about 12 inches from the trunk with a shovel and water it in.
