This evergreen shrub is well-known for having the star-shaped white flowers that bring with it a citrus smell between the months of April and May. But for the rest of the season, you can enjoy glossy foliage with leaves that look like small palm tree leaves. Colloquially referred to as the Mexican orange blossom, the species made its way to Europe in 1826 and ever since then has become a popular shrub for the small amount of attention and maintenance required, and more importantly the ability to thrive in any soil against any diseases or pests, and with no pruning. Busy gardeners who don’t necessarily have a lot of time to carefully cultivate the plants that fill their garden will love investing in this one. With this guide you will learn everything you need to properly care for, propagate, and maintain your choisya ternata.

How to grow choisya plants

The shrubs are actually quite simple to care for and once they get established they don’t need much maintenance from you except for the odd prune to keep them within the desired size.

Position in full sun where possible

Where you position your garden plants is going to be based on the variety. While all varieties require some sunlight, there are a few that are more tolerant of shade than others. So, be cognizant of the variety you have selected and whether it absolutely needs full sun or can tolerate partial shade. Regardless of variety be sure to position the shrub so that it is sheltered against the stronger winter winds and usually the more sun the better.

Water young plants, established plants are drought tolerant

When you first plant your shrub you need to water more prolifically to make sure it doesn’t dry out. But once it gets established it becomes very drought-resistant and will typically tend to itself, only needing watering during a prolonged dry spell. If you are facing a drought you can soak it weekly and that should be just fine.

Grows well in most well-drained Soil

This particular plant is happy in loam soil, clay soil, or sandy soil. They don’t require overly rich soil. This type of flexibility makes it easy to grow, you just have to make sure the soil isn’t waterlogged and it usually grows well in just about any soil.

Apply fertiliser such as bone meal when planting

The Choisya rarely needs fertiliser. The only instances where it would be a requirement are when the soil in which it is grown is very poor. If so, you can add fertiliser such as bonemeal to the soil and mix in lots of compost to the area before planting the choisya and feed again in Spring with a balanced fertiliser.

The time of year to plant is much more flexible with the Choisya. You can choose to plant any time so long as the ground is not frozen but try to avoid planting in winter as they will not be actively growing and will not put out any root. If you plant in the summer when it’s very dry you will have to water a bit more regularly than normal to make sure your plant is well established.

Planting March to April is best, or September to October

Ideally, the weather will be just mild enough with adequate rainfall if you plant between the middle of March and April or between the middle of September and October while the ground is still warm and there is still time for it to put some root out before winter. Most of the time if you plant within one of these two windows you can effectively forget about the plants without having to do much maintenance except keep it watered for the first few months.

Choosing a spot for your plant should be done carefully. This plant needs protection against stronger winds but it also needs enough space to be able to reach full height and spread. Some of the varieties have a spread that spans 2.5 meters so you’ll need to be cognizant of the space you have in your garden before planting unless you plan on pruning it to control the size.

Improve poor soil and improve drainage if needed

Clay soil is not necessarily bad or nutrient poor but it does tend to be heavier with bad drainage which is usually the real problem. When you dig a hole it can act as a sump and holds water, some plants then essentially drown or rot off because the roots are constantly sat in water. To that end, you can lighten it with some compost to give it better drainage and lighten the compact nature of it.
Improve poor soil by incorporating plenty of farm manure of compost into the soil

If the soil you have in your garden is poor, you can add compost or well-rotted manure to the soil to add more nutrients prior to planting. you can also add horticultural grit if the soil is too waterlogged and this will improve the drainage you can enjoy.

When you are ready to plant be sure to dig a hole that is twice the width of the root ball. Add anything to the soil as necessary such as grit, or perhaps compost or bone meal. Place the plant inside the hole making sure that it remains at the same depth as it was in the pot. Then back still the whole around the roots and firmly pressed down on the soil to solidify the soil, remove air pockets, and allow it to settle. Concurrently water it well so that the soil settles in around the root ball.

Growing Choisya in pots

If you are growing in pots it’s advisable that you pick a compact variety and you still plant in a pot that is fairly large, spanning between 40 centimetres and 60 centimetres at least to accommodate for the larger root growth. Once you plant in a pot you will need to give it a much more thorough soaking, usually once a week until such time as the roots have established themselves but as with most shrubs, regular watering is probably needed if grown in pots.

Choisya care

Choisya care - In terms of maintenance, when your plant is young you should remove any weeds around it to allow for proper health. Once the plant establishes itself it will naturally crowd out the weeds that are trying to grow. You can add mulch once a year to help keep weeds minimal and retain moisture. When you do add the mulch though, place it a few centimetres away from the plant stems.

Moving choisya plants in the garden

If you need to move the shrub at any point do not damage the roots or your plant will struggle to reabsorb the nutrients and water necessary to acclimate to its new location. Rather than transplant, you are much better off pruning your shrub back in the month of June so that there’s less stop growth. If you absolutely have to move it, prune it in June and then move it in the autumn. Given the size of the plant you will need to carefully dig around the root structure and you may need more than one person to help lift it and transplant it. When you bring it to its new location be sure to add compost to the new hole to help aid the recovery.

Plants that are grown in containers will need extra protection during the winter time so you should place them someplace sheltered such sheltered corner or inside a cold greenhouse if possible. You can also add an extra layer of protection with bubble wrap around the pots but even in extreme conditions make sure you water them here or there.

If you have to repot it choose a container that is larger than the original container to accommodate an excessive amount of improved root growth.

Pruning choisya

When you are pruning, the only reason you would prune is to keep your plant at a certain size in the middle of June. During that time you want to wait until right after the major flowering has finished and then you can cut it back to about half its original size or less depending on how much you want to remove.

This is something to do if the plant is outgrowing the space in which it was planted or it is outgrowing the pot in which it was planted. If you do this always mulch the base of the plant with some more compost or apply bone meal mixture to help it recover after pruning.

Other than the specific cases you realistically do not have to prune your plant at all. It will thrive just fine.

Propagating choisya by taking cutting

You can propagate from seed but the most effective method is actually by taking cuttings. Cuttings need to be taken from new growth just as they are becoming firm at the base but still flexible at the top. Usually, this is around the end of summer.

Prepare the pots ahead of time with a mixture comprised of half grit and half potting compost so that the drainage is appropriate. Make small holes in the mixture using a pencil or a stick, so that you can place the cuttings directly into the hole.

Remove the tip of the stem and divided the remainder of the stem into segments or cuttings that are 10 to 15cm in length. You want to make sure that the base of each cut takes place right above a leaf node. After that remove any of the lower leaves and then dip the cutting into a rooting powder to help it grow new roots as quickly as possible.

Place the cuttings into the pots you have prepared approximately 5 inches deep. Water it gently and cover it loosely with a plastic bag. This will prevent moisture loss. In effect, you want to create a tiny greenhouse for each container. So you might use a plastic cup that you place over a smaller pot or you might place a plastic bag that you secure with a rubber band. There are plenty of options but the purpose is the same regardless.

Place all of the pots in a sheltered location out of direct sunlight but keep them warm. You will need to remove the cover or the plastic once a week to lightly water and allow the cutting to air. Doing so also alleviates any problems with poor air flow. By the following spring, the cuttings should be ready to go outside on a daily basis for hardening off. Once they have become acclimated to the outside whether you can plant them.

Pests and diseases

Snails and slugs will eat young plants

In terms of pests, these are rarely affected because of the scented oils that they have in their leaves but you might see slugs or snails on the younger plants. To alleviate this problem you can sprinkle grit around the plant because slugs and snails simply won’t want to crawl across that. Alternatively, you can use slug pellets and sprinkle them around the plants

In terms of diseases, the plant is pretty much disease-free. On occasion, you might get root rot but this can be avoided by simply improving your drainage and being careful not to over water. Other than that it is a very easy plant that requires no preventative measures.

Varieties to choose from

The original plants brought with them dark green leaves and white flowers come springtime. They also produce a second flush at the beginning of autumn. This variety will thrive best in sunny areas but can handle partial shade so if you don’t have any area that gets full sunlight all day, don’t worry, you can still capitalize upon the citrus fragrance that gives this plant its name.

There are different varieties other than the original green choisya ternata which you can choose. These varieties will typically reach up to 2.5m over the span of 10 years.

Choisya Aztec pearl

Aztec Pearl is one variety that features dark green slim cut leaves and white flowers that are lightly tinged in the early summer with pink. These flowers are very popular because they are not only stunning in their design but they have a prominent gold stamen and produce the Citrus scent for which this plant is so popular. These varieties will reach 2.5 meters over the span of 10 years and they prefer sunny locations.

Choisya White Dazzler

White dazzler is a more compact shrub better for smaller gardens or for growing in pots. It doesn’t require a lot of pruning and if you grow in multiple pots or in large, long pots it will make for a very suitable hedge. It produces slender, dark green leaves and an abundance of flowers both in the spring and the Autumn. This is one of the strongest of all varieties but it prefers full sun and at its full maturity around 5 years it will reach the ultimate height between 0.5 and 1.2 M.

Choisya ‘Sundance’

Sundance is another variety popular for the foliage in particular. As the leaves begin to start growing they have a sunny, yellow colour and when they reach maturity they become lime green. This provides beautiful backdrops from March through November and can still provide a hint of dazzle to a winter garden that is otherwise mundane. The richest colours can be achieved if the plant is placed in full sun. Like the other varieties, this one produces white flowers with a citrus scent that will show up twice per year, once between May and June and again in October. Around five years it will reach full maturity and 2.5m in height.
