Potted strawberry plants produce runners that eventually take over the container in which they grow. When this occurs it is necessary to thin the plants and either dispose of or replant the thinned strawberry plants. Repotting strawberry plants isn't a difficult endeavour thanks to the plant's ability to survive root loss. You can repot strawberry plants during cool weather to combat shock, which can prove fatal to vulnerable strawberry plants.
Use your fingers to gently remove the topsoil away from the strawberry plant. Dig down a little to remove more of the soil, to make sure that the plant isn't obstructed beneath the surface. Remove any debris that may hinder the safe removal of the plant such as mulch pieces or other plants.
Fill a separate planter or container with potting soil. Use potting soil that is recommended for growing strawberry plants or another organic blend. Add peat moss to the soil to improve water retention capabilities. For example, for every 2.27kg. of potting soil use 0.454kg. of peat moss. Mix the moss and soil together thoroughly.
Burrow a hole in the new container of soil and moss in the size of the strawberry plant you are repotting. Use your hands or a gardening tool of your choice. Dig down no deeper than 5 inches.
Dig down approximately 9 inches beneath the strawberry plant you are removing. Do this carefully with a gardening tool or your hands. Sometimes strawberry plants produce roots that grow several inches long.
Scoop a digging tool or the palm of your hand beneath the plant where you just dug. Pull your hand upward gently as you carefully pull the strawberry plant from the soil. Be careful to keep as much soil around the roots as possible. Keeping the root ball well covered protects the plant from going into shock. If some of the roots of the plant are damaged, it is OK. Strawberry plants are resilient.
Place the strawberry plant, gently, into the burrow in the new container. Place the roots aiming downward into the hole. Draw excess soil around the plant loosely to fill in the hole and protect its roots.
Water the plant lightly.
