It’s difficult to estimate just how fast ajuga spreads because of the variance in the growth rates from region to region. It is known that ajuga spreads more quickly in warmer climates and slows down as winter approaches.

In most cases, it will spread one foot per year for every twelve inches of height if left uncontrolled. This means that an untreated plant may reach up to five feet tall within three years!

It’s important not only for personal gardens but also for agricultural fields and natural areas alike to be mindful of this pesky weed before it becomes unmanageable. This article provides all the information you need about how fast does ajuga spread, what makes it such a valuable plant in gardens, and more.

What Is Ajuga?

What Is Ajuga

An upright plant that grows quickly and spreads rapidly, ajuga is also known as bugleweed. It’s part of the mint family Lamiaceae. The leaves are typically dark green with purple flowers in the spring.

Variations of this flower may come in colors such as white or pink as well. Ajuga prefers to grow naturally in beds and borders to find it among other smaller herbaceous plants easily.

Why Do People Use Ajuga?

Ajuga is widely used in the gardening community because of its ability to attract pollinating insects and give off a pleasant fragrance. People who love bees and butterflies will often plant this flower along with other herbaceous plants because it’s an easy-to-grow plant.

Many people like using bugleweed as well for their wildflower gardens or simply growing them close together to create a thick border.

Here Are Some Tips On How Fast Does Ajuga Spread

Because ajuga is very adaptable to different soil conditions, the growth rates from region to region may vary. However, one thing remains consistent across climates: it spreads quickly and will flourish if not treated properly. The following are the most important tips on how fast ajuga spreads:

Be Aware Of Ajuga’s Spread

Be Aware Of Ajuga's Spread

Ajuga might overtake your garden or natural area if you aren’t careful. The best way to deal with the problem is to be aware as soon as possible so that quick action can be taken to stop its spread before it becomes unmanageable.

Pull Up New Plants As They Grow

If you find ajuga growing in your flowerbeds, the first solution should always be hand-pulling or digging it out by the roots and disposing of properly. If this isn’t done regularly, you will run into trouble with a large patch of these plants later on down the line.

Use Herbicides Sparingly

The next step would still be to pull up the ajuga by the roots if it has already taken over an area or is growing too quickly. However, there are several types of herbicides that can kill off large patches of this weed. Again, we recommend using only as much herbicide as necessary and following all instructions for proper usage and disposal.

Use Other Natural Methods

There are also several organic solutions you can use to spread through your garden instead. For example, mixing equal parts salt and vinegar together and applying it to the leaves will eventually wilt the plant after multiple applications.

Another option would be to plant daffodils around your garden because they naturally ajuga reptans (although they will also keep other herbaceous plants away).

Be Aware Of The Other Dangers To This Plant

Ajuga can be dangerous in more ways than one. The flowers are often very attractive to bees and butterflies, which is why people like to use bugleweed for their wildflower gardens.

However, if you have pets or small children in your garden area, it’s important to watch out for the pollen produced by these flowers because it can also be harmful if consumed.

Do Not Compost Ajuga

Do Not Compost Ajuga

Ajuga is one of the few plants you should not include in your compost or fertilizers. Not only does it have stolons that grow rapidly, but the roots can also sprout new plants just as easily.

Prevent Spreading Through Seeds

Birds and other animals scattered through their droppings can spread seeds from ajuga. If you want to cut down on the number of new plants growing across your garden, you need to take some precautions when dealing with existing bugleweed.

For instance, always wear gloves when handling these flowers (and wash thoroughly after use). Also, remember never to dispose of weeds into waterways where they might end up in rivers or lakes because this can easily affect local ecosystems.

Remove The Flowers If You Want To Prevent Spread

Ajuga produces gorgeous blooms that are often very popular with gardeners because of their aesthetic value. However, these flowers are also one of the fastest ways bugleweed can reproduce.

If you want to stop this weed from spreading across your garden, cut away all the flower buds before they are fully open.

What Makes Ajuga So Valuable In Gardens?

One of the biggest reasons people like to use ajuga in their gardens is because it requires very little maintenance while growing. Bugleweed needs proper sunlight and rich soil while offering porous drainage for optimal growth.

It also prefers alkaline soil, although some types can grow in acidic soils as well (although this will stunt the plant’s height).

How To Control The Spread Of Ajuga

How To Control The Spread Of Ajuga

It is good to discard ajuga seeds and then remove new plants as they sprout. Before the roots can grow too deep or harden, this needs to be done, so it’s important to act quickly.

Removing all flowers will also prevent future spread by seeds. When trying to stop bugleweed from growing in your garden area, there are several steps you should take:

Step 1: Grab the plants from the ground cover with a shovel before they go dormant. Remember that you will need to remove as much of the root system as possible if you want these plants to die out for good.

Step 2: Use another shovel or your hands to remove all soil around the plants. If you are planting new grass or other flowers in the area, do this before they can take root.

Step 3: Throw out all the plants in your compost pile so they can decompose naturally. Alternatively, you can burn them if it is legal in your area, and keep in mind that the smoke will be toxic to animals in the surrounding area, especially if it is windy.

Step 4: If your ajuga problem is small enough or in an area where you can’t dig up all the plants, you can use vinegar to kill off bugleweed. Soak the individual leaves of the plant completely with white vinegar and wait for it to wilt. Repeat this step if you see new sprouts coming out through the soil.

Step 5: Use high-quality garden mulch after treating your area with vinegar or digging up all existing bugleweed plants. This will help prevent further spread by seeds and help preserve moisture in the soil, making it harder for weeds like ajuga to grow.

Tips For Planting Ajugas In Your Garden Or Landscape

Tips For Planting Ajugas In Your Garden Or Landscape
  • Ajuga is one of the easiest plants to grow in your garden because it doesn’t require any special conditions like high humidity or rich soil.
  • Ajuga can be planted in full sun or partial shade, although make sure it gets at least 6 hours of sunlight a day if you want it to reach its full height.
  • It is generally okay to plant bugleweed directly in the ground, although you may have to water it often at first if rain is scarce.
  • If you are planting ajuga in a pot, just make sure that it has good drainage and only use well-draining soil. Also, keep in mind that bugleweed prefers alkaline soil conditions.


If you’re looking for a low-maintenance plant that is easy to grow, has beautiful flowers, and thrives in tropical climates, then Ajuga might be a perfect choice. Just make sure not to let your plants flower, or they will produce seeds that can spread quickly across gardens while also attracting bugs.
