How To Transplant Herbaceous Perennial Plants - Part 3

Updated on March 7, 2012

Digging Up A Clump


In the previous article (How To Transplant Herbaceous Perennial Plants - Part 2), we found and prepared the new location for the plant we were transplanting, and began digging around the plant to remove it from its present home. At this point, consider the size of the clump you are removing and decide if you want to move it all into one spot, or divide it into two or more new plants. (In the next article I will cover the situations when you do not wish to divide a plant.)

Whether or not to divide will depend on the size of the existing plant as well as the size of the place to which you intend to move it. In this case, once I had cut around the false sunflower clump I realized I’d need to divide the plant into at least three clumps in order to move it. This decision was based on the size of the existing clump and my physical limitations: hoisting more than a third of the plant once I’d gotten it out of the ground would not be possible for me alone. Had I had help with this project, I may have moved the entire plant, although as I considered my options I thought of several places I could use a sturdy, very tall, late-blooming plant like the false sunflower, so dividing it became the new plan. Because of this choice, I then stopped working on the existing clump and dug two more holes where I wanted to relocate the new clumps.

Going back to the existing plant, if you are dividing the plant, cut vertically into the clump, forming pie-shaped wedges of the size and number you want. Then go back to cutting around the circumference of the entire clump, pushing the blade of your shovel deeper into the soil each time and directing it inward toward the center of the plant at a steep angle. Lever the plant using the shovel, and pop it bit-by-bit out of the soil. Deepen the cuts through the interior of the clump until you have as many discreet new clumps as you desire, in this case, three.

Moving A Clump To A New Home


Working quickly so that the roots suffer as little drying as possible, move the clumps to their new locations. Place them in the holes you dug, deepening or filling in the holes as need to keep the top of each clump in line with the soil around it. Use as much of the soil you dug from the hole to backfill around the clump, paying particular attention to getting dirt packed around the sides of the plant so that its roots are in continual contact with soil. Do not allow any roots, however small, too remain above ground. Tuck them all in and do not be afraid to pack the soil tightly, using your foot to tamp it in. The most common mistake people make when transplanting is to leave the soil loose around the plant. Do not be afraid of damaging roots; any harm you do is more than compensated for by the benefits of getting good root-to-soil contact.

Planting The Clump


Water each clump thoroughly, then do it again. The biggest threat to a moved plant is the presence of pockets of air among its roots. Tamping the soil well and watering thoroughly will help eliminate that threat. Only after your plant is well-settled in its new home should you go back to the hole from which you removed it and backfill it, using soil left in the wheelbarrow and any additional topsoil needed to complete the chore. Depending on the weather, water the moved clumps every rain free day for the next week, then every third day for the next three weeks, being careful not to over-water and drown the plant. The amount of water needed will vary widely depending on your garden soil, but the goal is to have moist but not sodden ground and to never allow the soil to completely dry out. You have successfully moved and divided your plant; relax and enjoy, knowing you’ve given it the best start possible in its new home. Next, I’m going to discuss dividing perennial plants in more detail, offering some advice on which plants benefit from periodic division and which do not.
