Artemisia shrubs are popular border and accent plants in many gardens and landscapes. They are very hardy and robust plants that make excellent candidates for transplant propagation. Transplanting an artemisia plant is not difficult, but it does require some patience and preparation. Here is a guide to help you transplant your artemisia.
Step 1 - Prepare the New Location
Before removing and dividing your Artemisia plants, you should prepare the soil where you plan to plant the new divisions. Turn the soil with good quality compost and add a quality, all-purpose fertilizer that is high in phosphate. In addition to the fertilizer and compost, you might want to consider adding chicken or cow manure, or another type of super phosphate. The added nutrients will help the root system of your newly transplanted artemisia plants develop more quickly and help resist root rot.
Step 2 - Dig Out the Mature Artemisia
Carefully dig out the mature artemisia plants you wish to transplant. Begin digging your artemisia plants at the tip line and work your way inward while making sure to cleanly cut any roots that extend out past the drip line of the plant. Use a garden spade or knife to make clean cuts to the root system.
Step 3 - Divide the Artemisia Plants
Once you have dug out the Artemisia, use your knife or garden spade to divide the root ball into halves or quarters. Try to keep as much of the crown section as possible when dividing the clumps. If the Artemisia bush is rather large, you may need to divide the root ball while it is still in the ground. If the size of the bush allows you to lift the entire plant out of the ground, do so before dividing the root ball.
Step 4 - Dig Holes
Dig holes for your artemisia transplants and space them about three or four feet apart. Also, dig the holes at the same depth of the original artemisia bush. You will need to space your holes far enough apart that the root system can grow large.
Step 5 - Plant the Artemisia Transplants
Insert the artemisia divisions into the holes and pack soil around them. Pack the soil tight enough to make the artemisia plant stand upright, but do not damage the plant when packing the soil. Add a layer of mulch to help protect the new division transplant.
Step 6 - Add Fertilizer
Apply more fertilizer to help promote better growth.
Step 7 - First Watering
After applying the fertilizer, water the new divisions thoroughly. Give the Artemisia transplants enough water to promote good growth but do not soak the transplants to the point that the soil cannot properly absorb the water.
Step 8 - More Fertilization
Young Artemisia transplants should be fertilized about every three or four weeks until the root systems are well established and the Artemisia is beginning to grow well.
