How to grow Skimmia – Growing and Care Guide
Last Updated on March 9, 2020 by John
Skimmias are evergreen shrubs that reach about one meter in height and spread once established. They are grown for their stunning foliage and if you have a male and female plant growing together then you can enjoy stunning berries from the female plant that makes they especially good for providing winter interest.
Grow Skimmia shrubs
Before you plant one of these shrubs you need to make sure that you have the appropriate garden conditions with the soil type being important which we talk about in a moment.
Plant in semi-shade positions where possible
Firstly, this shrub needs semi-shade throughout the entire year but they can tolerate some conditions with full shade. If you have a very low light situation they will become quite leggy but they won’t die. They naturally exist in forests where low light is quite common. If you have an area in your garden where you plan to grow the shrub and it has full sun, it will very easily burn the leaves which is why open sunny sites as best avoided.
Ideal for planting in the ground, growing on containers or for creating a small hedge
They need to grow in either the ground or a container that is able to accommodate their mature size of at least one metre in height and spread. If you want to grow them as a hedge you need to make sure you plant them at least 45cm apart to create a good thick hedge.
Plant in slightly acidic soil or ericaceous compost if grown in pots
They prefer slightly acidic soil but they can tolerate neutral soil. If you have alkaline soil, you will need to modify it every year in order to accommodate these plants.
They are very tolerant of drought especially if they’re not grown in containers but directly in the ground because their leaves maintain moisture so if you have trouble with drought where you live these might work out quite well. They will, however, need plenty of water until established but after this, they are generally ok left to there own if grown in the ground.
Perfect for the less green-fingered of us
They do tolerate a great deal of neglect so if you’re the type of gardener who likes to forget about your plants this is a great option. They grow very well without any pruning and they have a very low nutrient requirement. From November onward they produce flower buds which gives them there winter interest that opens into flowers between March and April.
Again if you have a male and a female plant together they will eventually produce red berries but if you have just a male plant on its own or just a female plant on its own they won’t. Do not eat these berries however as all parts of the shrub can cause discomfort if you eat it including the berries so be sure to leave them for the birds.
Different varieties to choose from
In the UK the most common variety is the Skimmia Japonica. It’s very strong and it produces flowers that grow quite freely. There are a few other varieties you can find in the UK though including Skimmia rubella (also very popular), Skimmia fragrans, and Skimmia nymans which is a Japanese female Skimmia which will produce red berries if planted with a male skimmia such as ‘Kew Green’, ‘Rubella’ or ‘Fragrans’.
Skimmia rubella has deep green leaves that are quite leathery and it produces purple and red flower buds that open into small white flowers.
Skimmia fragrans has light pink and green flower buds but is otherwise the same.
How to care for your Skimmia
Once you decide on the variety you want, they all require the same level of care and thankfully that level of care is quite minimal. As mentioned they can withstand a great deal of neglect given that their natural habitat is alone, isolated in the forest.
Test the soil to ensure is slightly acidic and improve if needed
You can grow them in the ground or in pots as mentioned. In terms of soil they do best with slightly acidic soil so if you are unsure what type of soil you have it is recommended that you get an at home test kit so that you can test the soil. If you have neutral soil you can always amend it ever so slightly so that it becomes slightly acidic. You can add things like sulfur to increase the acidity or mix in some ericaceous compost when planting.
Choose a semi-shade position for best results
Choose a location in your garden that gets semi-shade all year round if possible. Full shade, as mentioned will be fine as long as the plant is able to get natural light but it won’t perform as well.
Choosing a pot
If you want to grow it in a container, make sure that you pick one that is well suited for its current size and pot up every couple of years as the plant reaches maturity. A plain terracotta is best because of the color contrast with the foliage but it’s not a requirement.
Choosing the right compost
Make sure you fill the pot with ericaceous compost and check for the acidity in the soil. Ericaceous compost is sold at most garden centres and nurseries.
Feed with an ericaceous feed
Feed it with ericaceous plant food in March and August and make sure it’s properly watered when conditions get quite dry, especially when growing in pots. In the ground, they don’t require much care once they have established themselves.
Rainwater is better than tap water because most tap water in the UK is too alkaline and these plants as mentioned prefer acidic conditions and that includes acidic water. A good solution is to collect and store rainwater using a water butt.
These plants are quite frost hardy and they will survive even the strongest of UK Winters when grown in containers. It is, however, best that you move them next to your house from November through February so that they get a little bit more protection against the cold and the wind to prevent the foliage getting burnt.
Pests and diseases
Skimmia is generally not effected much by pests or diseases but they have been known to be attacked by spider mites but this is something that is best ignored and usually won’t cause any significant harm. However, if you feel the need to, you may want to spray them with a pesticide but this is often not needed. The only other pests to watch out for are snails, they will leave holes in the leaves. As with all plants, the best way to combat this is to use slug traps or slug pellets but we try to keep thing organic so would always go for slug traps first.
Yellowing of leaves
The problem your much more likely to have is magnesium deficiency which causes the leaves to turn yellow. This happens because of soil conditions but can be amended by simply adding Epsom salt to the ground and you usually see the effects within a couple of months
One final reason is simply a nutrient deficiency caused by the soil being too alkaline. This is also an easy fix and can be treated by simply adding ericaceous compost to the soil or topping up pots and then giving them a fed with an ericaceous feed.
