A Schedule For Repotting | Michael Hagedorn

When is greatest to repot? Can we repot them all of sudden?

The final guideline to repot as they break bud is an effective one. Some, like pines, although, are greatest repotted a bit earlier than we see bud elongation. Maples, as buds open.

You probably have a protracted spring—one which goes on at a light temperature for a pair months or extra—then the schedule separates into phases.

A protracted spring schedule may appear like this:

  • Deciduous first: Quince (Japanese and Chinese language), Trident
  • Then, Black Pines
  • Satsuki, as they inexperienced up
  • Single flush pines, like Japanese White and Ponderosa
  • Spruce
  • Then extra deciduous, like Japanese Maples, Elm
  • Hinoki
  • Beech, Hemlock
  • And eventually, Juniper

In case your spring is brief, only a month, bushes could also be repotted roughly on the similar time.


Bud swell on Hemlock, about proper repotting timing


Ponderosa Pine—a bit late


Black Pine—a lot too late


Ezo Spruce—the tree on the proper, appropriate repotting timing; tree on the left, too late. Difficult for this specimen as it’s a forest…attempt to gauge by the primary tree to start transferring.


Beech—a hair early. Beech are tough. They’re late openers, normally nearly in a single day. Ideally, look forward to a little bit of inexperienced between the bud scales to indicate, then repot.


Vine Maple—like many maples, they are often repotted a bit “lengthy within the tooth”, when the buds are swelling and opening


Although Maple will be repotted with buds opening, as soon as leaves are out it’s on the late facet

If repotted outdoors its very best window—earlier than or properly after bud break—place the tree in shelter, ideally a greenhouse for a number of weeks. Greenhousing any repotted plant is an effective follow for defense from wind, frost and an excessive amount of rain. A typical mistake is placement in an excessive amount of shade after repotting. Vegetation want gentle to develop roots, and in lots of places the spring solar is gentle.
