 GROWING ESCALLONIA IN CONTAINERS

First, you will need to choose a container that is large enough to hold the shrub in question and also will be well balanced. A half barre; is ideal, but whatever you choose make sure it has plenty of drainage holes. Fill the container with a 2cm layer of gravel to aid drainage further and on top of this add multipurpose compost to which a handful of fish, blood and bone has been added.  Fill the container to within 5cm of the rim.

It is best to plant in spring so that it gives the plant enough time to establish before winter arrives.

Dig a hole at the centre of the container slightly bigger than the root ball it came in the original container. Drop the plant in so that the top of the root ball is at the same level as the top surface of the compost in the container.

Backfill with the growing media, making sure that no vacant areas remain, using more compost if necessary. Firm the plant in and water well.



 BEST GROWING CONDITIONS

You will need to grow Escallonias in full sun or partial shade to do well.

You will need to water frequently during the first season so that the plant will establish quickly. In heatwaves, you will need to water frequently at least once every 2 days, but when established it can take less watering. It is best to water when 5cm below the top surface of the compost feels dry to the touch. Water until it just emerges from the drainage holes.

Feed every spring with a general-purpose slow-release fertilizer. This will give enough energy to the plant so that it will do well during the growing season.

You can prune Escallonia hedges by trimming lightly after it has finished flowering. Only do this once, otherwise, the number of flowers will be reduced. Do not be tempted to do it too frequently as the result will be a neat bush but fewer flowers.

For standalone shrubs, you can prune congested and overgrown shrubs by thinning using the ‘One in three’ method. In autumn, cut back about one-third of old branches that have flowered. You can cut them near to the ground or where two main stems join. This can be repeated in subsequent years to gradually regenerate the shrub.

To propagate you will need to take in late summer some semi-ripe cuttings. Use a sharp knife to cut just below a leaf joint and remove the leaves on the lower two-thirds of the cutting. Dip the base in hormone rooting powder and place the cutting in a small pot full of moist seed and cutting compost.

Place the cuttings in a cold frame and allow them to grow on to be planted out the following year.

PESTS AND DISEASES

Escallonia does not seem to be attacked by pests but in the terms of diseases, they are not so lucky. They can suffer from fungal diseases, especially if the plant is stressed. You will notice that dark spots will appear and the leaves will turn yellow and fall, If the disease is very bad, you will lose most of its leaves. To avoid this, you will need to collect all fallen leaves and by picking off the worst of the discoloured ones.

Watering regularly and looking after the plant will help keep the disease from reoccurring, Pruning as suggested will provide air circulation around the plant and prevent the fungus from taking hold in the first place.

Escallonia does not like dry winds or low winter temperatures. Prolong heavy rain or long dry spells of drought will result in the plant losing leaves,

If frosts have killed any young shoots, wait until mid-spring before pruning out as at this stage it will become clear to see where the dead areas are and where new growth begins.
