By following these simple steps, you will ensure your potted climbing rose gets off to the best possible start.
Here’s what you’ll need to plant your rose:
David Austin’s Mycorrhizal Fungi (not available in all states)
Before removing your rose from its pot, water it generously.
Using a fork, dig the soil over thoroughly and remove any weeds or stones. This will ensure that the new roots can venture freely in their new environment.
Dig a hole that is wide enough and deep enough to hold the rose’s root mass. This should be approximately 20" wide and 20" deep or approximately twice the width of the pot and just a little deeper. If your aim is to train your climbing rose to grow up a wall or frame, make sure you dig your hole directly against the structure.
Using a fork, break up the soil at the base of the hole. This will allow the roots to go deeper into the soil.
Mix a small spadeful of well-rotted farmyard manure with the soil in the bottom of the hole. This will add vital nutrients to the soil helping the rose to establish more effectively. If you can’t source manure from a local farmer, your nearest garden center will offer something similar.
Sprinkle the recommended amount of Mycorrhizal Fungi around the sides and the bottom of the planting hole. This will aid root development.
Carefully remove the rose from its pot and position in the center of the hole. If planting against a wall, angle the stems pointing towards the wall and the roots away from the wall, at a 45 degree angle. Place a bamboo cane horizontally across the top of the hole to judge if the planting depth is correct. The soil mass around the roots of the rose should be just below the bamboo cane or 2-3” below ground level in cold winter areas.
Fill in and around the rose using the soil that was originally dug to make the hole.
Lightly firm the soil around the rose with your foot to ensure that the rose is secure and that there are no air pockets in the soil.
Water the rose well after planting. For tips on how much water your rose needs click here.
