How to Plant in Gardening Containers
To ensure that plants in gardening containers grow and perform as well as possible, you need to plant them properly.
Step 1: Water Prior to Planting
Water the plant thoroughly about an hour before planting, then position it—still in its original pot— inside the new container.
Step 2: Add Potting Mix
Add potting mix to raise the plant to 1 in (2.5 cm) below the rim; this allows space for watering. Also add potting mix around the sides.
Step 3: Firm Mix
Firm the potting mix well around the pot. Lift out the plant in its pot, leaving a hole in the potting mix. Remove the plant from its original pot.
Step 4: Tease Root Ball
If there is a tight mass of roots around the root ball, tease them out gently. Place the plant back into the hole in the potting mix, and firm in.
Step 5: Give it a Good Watering
Check that the plant is at the same depth as it was in its old pot. Then cover the top with a little more potting mix, and water well.
Step 6: Add Mulch
Finish off with a layer of ornamental mulch. This helps to retain soil moisture and suppresses weeds, as well as anchoring the pot.
