Transplanting or Moving plants

Now is the time to move plants

If you are considering moving any of your perennials or herbs now is the time.  They need at least 3 weeks to reestablish good root growth and you want that to occur before any signs of frost so August is the month to do it.  I moved 8 plants from the community garden to the new back yard last fall and all of them thrived this spring except one (the lemon balm died?!?). 

This was when we moved and I prepped the bed and moved my plants at the end of August beginning of September so they would be hardy enough to make it through the winter. As you can see they are much larger than the plants I put into the garden this spring, so that establishment of worked well.

Why Move A Plant?
There are many reasons for moving a plant. It may have outgrown its location. It may need more or less sun than it receives in its current location. It is overtaking plants around it.  Or even it looks out of place with the others near it.  Whatever the reason, the degree of difficulty depends on the size of the plant.  The mint plants here are crowding out each other and cross pollinating, so they have to be separated.  That is the task I am undertaking.

How to Move A Plant
For small plants, such as annuals, it’s just a matter of using a garden trowel to dig around the root ball and gently raising the plant (with root ball intact) out of its hole. For a larger plant, especially a well rooted perennial, you will need a shovel to dig around the plant and get deep enough to extract the root ball without leaving too much behind.  That cutting and tearing of the roots causes root shock and will set the plant back, which is why you need 3 weeks of good weather to help it recover before bad weather sets in.  Make sure you have already dug the hole for the new location, and used some of the soil from its current location to fill in the new hole. It’s a shock to the plant’s root system when transplanted, so the new hole should have “familiar” soil.


Step #1 – Prepare the New Hole
Dig out the soil where you want to plant.  Make the hole 1.5 to 2 times bigger than what you expect to place in the hole.  If the ground is hard, such as clay soil, you might want to dig out 3 times the size to give the plant more room to spread in future by loosening the soil now when there is no plant to work around. 
Then make a “new” soil, by combining what you remove with a top grade composted soil and some organic mater, leaf mold from the compost bin is great or you can use peat moss.  This time of year I have lots of leaf mold from last year’s leaf raking.  Refill the hole half way, to the expected right size for the transplant, and add some of the “old” soil to the bottom of the hole.

Step # 2 – Dig Up the Plant and Place in the New Hole
Using your sharp shovel (in other words, not a blunt end hovel like one you’d use for edging) dig down into the soil around your plant all the way around.  Do not yank or pull on the plant, just dig all the way around.  Place the shovel point underneath once the soil is loosened and pop out the root ball, you may have to cut through roots so be prepared.


Lift the plant from the bottom of the root ball and gently place it in the new hole. If the neck of the plant is level with the ground, fill the hole with the remaining soil mixture. If the neck of the plant is not level with the ground, adjust by removing soil or adding soil. Once the hole is filled in with the soil mixture, immediately apply water.

The second plant, to go against the fence, turned out to be much larger than I realized.  It was heavy and hard to lift and the ball was twice the size of the hole I dug.  I set the plant on the ground and dug another hole and then divided the root ball in half.  The roots were so thick I needed to cut them with garden shears to create two plants.  This can increase the shock to the plant so I carefully watered them a couple times that day and the next.


I generally place water in the hole before I bring over the plant and then again after I plant the plant and firm up the soil.  If the soil sinks around the plant be sure to add more.  You do not want roots exposed to the drying sun.  Apply water everyday for a week, so that the roots regenerate. After one week, apply an organic fertilizer or water with compost tea.


Step #3 – Observe Plant for Signs of Stress
The plant will experience stress after being transplanted. Signs of stress may include droopy leaves, yellowing leaves, dry leaves, and pale stem/branches. Insects and pests like to attack a plant when it’s stressed, so beware. Keep an eye on the plant to make sure it recovers and begins to thrive. About 3 weeks after transplanting, the plant should have resumed its normal appearance.
 

I find mints get very droopy but only for a few days.  If it persists longer, I start looking for causes and may add more of the native original soil around the plant or water less or more frequently depending on the feel of the soil.  If the soil is dry and crumbly I add more water and if it is soft and spongy I use less to allow it to dry out.  Remember that plants breathe through roots so a saturated soil can suffocate them.


All things working and your plant should be a happy camper in about 3 weeks.



It rained for days after the transplant so the plants were very happy and so were the weeds!
