Place empty plastic plant pots in the base of the container to stop the compost falling out of the bottom, and aid drainage.
Part-fill the pot, up to the first tier of planting holes, with multi-purpose compost. Add slow-release fertiliser granules and mix in with your hands.
Start planting up the pot, starting at the bottom. Use your hands to gentle place the plants in position, and firm them into the compost.
Add more compost and slow-release fertiliser until you reach the second tier of planting holes, and add more plants, firming them in. repeat this process until you reach the top of the container.
Add more compost to within 5cm of the rim of the pot, and firm everything in to remove air pockets. Water the pot well.
Allow the water to thoroughly drain from the pot before moving it to its final planting position.
