Re-Planting Flowering Plum – Why Did it Die?

Q. Is it too late in the year to replace a flowering plum
tree? Another in my yard is starting to blossom.

A. Whether to plant a new flowering plum tree or not has
nothing to do with its flowering time. The best time to plant is just before
new growth begins in the spring which is a week or two before flowering. But
there is nothing wrong with planting any time during the spring of the year. It
just so happens planting time also corresponds to flowering time as well.
            Another
great time to plant is during the fall months when temperatures are beginning
to cool, when it is not yet cold, and before leaf drop. In the Mojave Desert in
the spring begins around the first week of February, give or take, and the Fall
begins toward the latter part of September.
            I’m
curious about why you are replacing a flowering plum tree. If this was because
of borers that tunnel into the limbs and trunk, then you are fine planting in
the same hole. These insects do not get into the soil but spend their entire
life above ground.
            However,
if you are replacing this tree because of overwatering problems then it’s best
not to plant in or near the same hole. Root diseases like collar rot stay in
the soil and could pose a future problem for most trees and shrubs planted
there. Plant several feet from this area.
