Barberry Shrub Care: Tips For Growing Barberry Bushes

The following are some tips for growing barberries. They will help you grow a beautiful and healthy bush. These tips are based on my experience as a gardener and professional landscaper.

I have been growing trees, shrubs, flowers, vines and perennials since 1975. My goal is to provide you with all the information that I use when planning my garden or landscape projects.

You don’t need to spend thousands of dollars on expensive chemicals to keep your yard looking good. You just need to invest in time and care. Here are some simple steps that you can take right now to make sure your yard is looking its best:

1) Prune Your Trees Wisely – Pruning helps keep the size of your tree manageable.

It’s also a great way to add new life into the area without having to dig up old growth areas.

2) Mulch Your Plants Well – A mulched area provides better drainage and keeps weeds from taking over.

If you’re planting seeds, make sure they get at least six inches of soil.

3) Water Your Plants Often – Watering your plants regularly ensures that they’ll thrive.

Regular watering also prevents them from drying out and wilting. Make sure you water your plants every two weeks during the hottest part of summer (June through August).

4) Maintain Your Perennials – Make sure to divide your perennials every few years.

This prevents them from dying out and stops them from spreading into areas that you don’t want them to grow in.

5) Cut Your Grass Regularly – Mowing your grass helps it stay green and healthy.

It also makes your yard look more presentable to guests. If you want, you can also plant new flowers or other ground cover in bare patches.

Taking care of your yard doesn’t take a lot of time or effort. Just follow these steps and your yard will look great for years to come.

If you are looking for more guidance on how to care for your yard, you can always hire a professional landscaper to do the work for you. There are many companies that offer this service and it’s relatively affordable. If you’re on a tight budget, this might be the best option for you.

You can also get free advice from your local government. Most towns have a department dedicated to helping homeowners keep their yards in shape. An added bonus of doing this is that you’ll be contributing to the community and helping keep things looking great.

Have fun with this, and enjoy your healthy barberry bushes!

japanese barberry bush growing tips

The following text is taken from Wikipedia.

The scientific name for the Japanese Barberry is Berberis thunbergii. It is an evergreen woody shrub which grows between 3 and 5 meters high. Its leaves are bright green and are around 2 cm long and 1 cm wide.

Its flowers are yellow and have five petals, and appear from late winter to early spring. They are very small, only about 2mm across. The fruit that follows also has five sides and is a red color. The berries are very similar in size to currants. This plant is not related to the common Barberry (Berberis vulgaris) which can be a highly toxic plant.

The Japanese barberry is a native plant of East Asia which was introduced to Europe in the 1800’s. It has been widely planted as an ornamental shrub in parks and gardens. It was also used in landscaping in New Zealand due to its tolerance of coastal conditions and salt spray.

It is now established in much of the lowland parts of New Zealand.

The plant is a host for the caterpillar of the scarlet tiger butterfly.

This shrub is now becoming a weed in New Zealand and mainland Australia. It affects native plants in several ways:

1) It grows very vigorously, so its growth shades out other plants.

2) It spreads by producing many seeds, and its seeds can remain dormant in the soil for many years, so that when the conditions are right (such as after a bushfire), they sprout.

3) The small fruit are eaten by birds which then disperse the seeds in their droppings, but the berries contain small hooks which damage the insides of the birds’ intestines so that the bird suffers an infection and dies within a few days.

This is known as tripping.

4) The leaves and stems of the shrub are very toxic to many animals and humans if ingested, so the plant competes for nutrients without the use of poisons.

The berries are considered toxic to humans and may cause vomiting, diarrhea and gastroenteritis.

This plant has been declared a noxious weed in New South Wales, Australia, and its sale or distribution is prohibited or restricted in some other jurisdictions. In New Zealand it is illegal to sell the plant, though it remains perfectly legal to give it away. If you have it in your garden and don’t want it, you can legally give it away or even destroy it.

Pruning of established shrubs is very difficult as the shrubs put out many underground stems called rhizomes, which need to be dug up individually. The roots also easily put out new stems so that the plant can regenerate.

Weed Killers will not work. The shrubs can be killed with large doses of glyphosate (one brand of herbicide is “Roundup”) but the shrubs must be sprayed while they are in full growth and all the stems must be covered without any being left out. This is difficult and the shrubs can regenerate from any bits that are missed.

Also glyphosate is not without danger: always read and follow the directions and heed all warnings.

If you do get Roundup or a similar product, be aware that there is cultivated varieties of this plant which are legal in some places, such as Rosularia. These look similar but have different leaves and grow smaller. Do not destroy them like you would the noxious kind!

If you are really badly infested with this plant, it may be best just to move house. Alternatively you could employ someone with a bulldozer to plow your house up and move you house to a new plot.

The most effective long term method is probably to repeatedly burn the area, the plant will grow back but it is very susceptible to burning off. Alternatively, the vegetation can be bulldozed and repeatedly plowed to form a thick layer of dead organic material on the soil. This will take several years to become effective.

If you are really serious, you could consider building your house on stilts.

The best method may just be to learn to accept the plant and live with it. If you get rid of it, something else will take its place. It’s competition, but not necessarily the worst sort.

Nature finds a way.
