How to plant a shrub in a container
Steve Redman from Holland Park in London takes you through
the technique of planting a shrub in a container. For more basic
information watch "An introduction to planting in containers"
You will need
- A Shrub
- A container, large enough to allow the roots to grow. For
more information see "An introduction to planting in containers"
- Gravel or broken crocks - these are pieces of broken
crockery or pots that can be placed at the bottom of the pot to prevent
water logging. Polystyrene is a good alternative.
- Multipurpose or container compost
- A watering can
- You may also use slow release fertiliser and water
retaining crystals to help the plant survive
Step 1: Choose the plant
Buy plants with green and healthy foliage, and avoid any with
discoloured, dead or damaged leaves. When buying a shrub, squeeze the
pot to test whether the plant is easily removed from it's container.
The compost should be moist and stay together when you remove the root
ball. The roots shouldn't grow out of the base of the container.
Step 2: Prepare the container
Cover the base of the container with a layer of crocks. You
can also add a layer of compost and a layer of gravel for extra
drainage. Add more compost until the container is about half full.
Steve recommends mixing in a small handful of slow release fertiliser
and water retaining crystals to nourish your shrub and help it survive.
Step 3: Plant
To remove your plant from it's original container, put it on
it's side and gently squeezing the pot. Tease the roots around the base
of the root ball to help the plant grow in it's new pot. Place the
shrub in the centre of the container. Add more compost around the shrub
and firm it down with your fingers. The level of the compost around the
shrub should be about 2 centimetres below the rim of the container.
Step 4: Water
Although you can water your plants a few hours before
planting, Steve prefers to water container plants after they've been
planted to help the compost settle around the roots. Most shrubs have
large root systems that need a lot of water. The compost should be kept
slightly moist so check the container regularly and water when
necessary.
