garden transplantation experiments


i inherited a lot of plants from the previous owners of my house
and now i want to move them around. there's a lot of
conflicting advice on the internet about when it's safe to transplant
various plants and when it isn't so i'm just trying stuff
and logging the results here.

universal tips

WATER WATER WATER

plants love water, especially after a major disruption like
transplanting. every plant is different but giving them a good drink
once per day for the first few weeks after transplanting them
is usually a good idea.

it will grow back

a little bit of drooping or leaf loss over the first couple weeks
after transplanting a plant is normal. transplantation is very
stressful for plants and this is a common way for
plants to respond to stress.


hostas


hostas simply do not care. as long as the destination has dirt
you can happily transplant them whenever you like with little risk
of damaging the plants. i've aggressively divided and rearranged the
hostas in my garden several times and have yet to have a bad result;
within a few weeks they completely bounce back and you can usually
see them start growing again almost right away.

hostas really like shade but most varieties will tolerate sun too
so as long as you give them enough water it's hard to find a spot
they won't do well in.


peonies


i love all the peonies in my yard but they're placed
very haphazardly. there's conflicting advice on the internet
about when it's safe to transplant them so i'm going to
try a few things and report on the results.

one consistent recommendation that i intend to follow is
to wait until the plants have finished blooming before transplanting.
i didn't have the time or energy
to transplant my peonies in the spring
so i have no problem following this rule.

another more contentious suggestion i've seen is
that you should wait until later in the year to transplant so the
plants have a chance to store energy during the summer.

this is the claim i want to test.

this year all my peonies were done blooming in june so
i'm moving one at the end of june, right at the start of summer
then i'll move one in august, in the middle of summer
and i'll move the last one in september, just before fall

i moved the first peony from its previous home next to a fence.
it turned out to be two plants so i kept them together and 
planted them both in a new bed in front of my garage.

august 6, 2025

moved another peony from a different spot along the fence to the new
bed in front of the garage. it looks like the one i moved about a
month ago is doing OK; one half of it is thiriving but the other is
very wilted even though i watered it A LOT.

september 9, 2025

the last peony to move was a much bigger one near the one i moved in
august. the one i moved in august is still doing very well so i
assume this other one will too unless moving them later in the
season is somehow worse for them.

october 12, 2025

no significant differences between the plants i moved in june,
august, and september as the leaves start to fall and temperatures
drop. i'll post another update in the spring when things start
flowering but for now at least it seems like peonies don't much care
when you transplant them.

september 9, 2026

it's been a year and i transplanted another plant this year. the
plant i moved last september must have died over the winter
because it didn't come back up this spring. the first plant i
transplanted is doing great though, it even had blooms on it this
year even though it was just moved.

i moved another peony in augusut this year to the same spot by
the garage and it doesn't seem to be doing great. i read from a
few sources that it's a good idea to prune them after moving them
so i cut off all the parts of the plan that were starting to
wilt. this didn't seem to help much and despite frequent watering
it's continuing to wilt more and more;
we'll see if it survives the winter.
