7 Reasons for Brunnera Dying With How to Fix Your Dying Brunnera

1. Planting Mistake

Your Brunera plant may die in the seedling stage unless you plant it properly. If you plant the seed in the landscape first, it can’t take the stress of the soil. As a result, most of the time the plant dies at the bud stage.

Again, if the wrong method of direct planting is adopted, your plant may not survive for long.

Fixing Guide

The ideal place to plant seeds is indoors. By creating a suitable environment for the plant in a small container, you can easily create Brunera plant seedlings. Generally in eight to ten weeks, Brunera plant seeds are ready for seedling production.

In early winter, the seed should be placed in a medium containing good soil and kept in polybags at low temperatures. You can keep it in your refrigerator. Germination occurs within two to two and a half months after extraction.

To plant seeds in the landscape, they must be planted in early spring after the last winter frost. A space of 15-20 cm should be left between each seed.

2. Poor Soil Conditions

The primary component of Brunnera plants’ frequent growth is soil. The plant won’t get enough water and could die from dehydration if you put your brunnera in soil that doesn’t contain enough water and is constantly dry.

Again, the nutrients that plants require will not be present in the soil if the pH is too high or too low. As a result, issues including leaf browning, yellowing, and falling are apparent, and the plant may die.

Fixing Guide

You need to choose soil that is moist, well-drained and has nutrients. Applying organic mulch to the soil for seedlings is very effective.

Basically, the soil’s ability to retain water should be assessed before planting the tree. However, if it is already planted, you must thoroughly combine organic matter into the soil. You should use organic compost, in my opinion. 

You may prepare it by yourself at home with a variety of organic components that you already have on hand.

3. Lighting Issue

Both excess sunlight and low sunlight are responsible for the death of Brunera plants.

When you expose your plant to sunlight for too long, your plant’s natural biological processes are disrupted. Because only a certain amount of sunlight is needed for plants.  Again, excessive heat can cause scratches on the leaves and branches of winter-loving Brunera plants.

And when your plant is always in a dark environment, it stops the photosynthesis process due to lack of sunlight. Also, in the absence of sunlight, plants can be attacked by various insects and fungi that can kill your plants.

Fixing Guide

Basically, Brunera plants prefer full sun and shade simultaneously. So you need to make a proper plan to ensure adequate sunlight and shade for the plants.

You can put your plant where it will get morning sun for at least 6 hours. It can be a window in your room that faces east or north. Move the plant to a spot that gets warmth but not direct sunshine for the following three hours of partial sun.

To ensure complete full shade, you should use a shade cloth if your tree is in the landscape. I always use non-heat-absorbing colors when utilizing shade cloth. 

4. Lack of Water

Improper watering is harmful to Brunnera plants. If the plant’s water needs are not met, the plant will quickly run out of water.

And you must know that dehydrated plants cannot survive for long. If you look closely, you can spot dehydrated brownies. The leaves of the plant will look pale and the veins will be obvious. Leaves will fall and plants will fall to the ground.

Fixing Guide

Brunera plants should receive regular watering until they are fully grown. They should receive extra care during the summer months.

You must frequently water brunnera plants because they prefer damp soil. Waterlogging, however, cannot be produced. Before applying water, the soil should be examined.

You can water your plants using a simple way. Apply water liberally first. A 2-3 inch stick should be deeply embedded in the soil before the second watering. Water can be applied if the stick is wet on half of it.

5. Over Fertilizing

You may be surprised but it has been proven that over-fertilizing can kill your Brunera plant within days. Many gardeners think that if more fertilizer is applied, the plant will grow more, but the reality is completely opposite. 

Whenever you over-fertilize your plants, the excess salinity will cause toxicity to your plants. As a result, your plant will suffer from fertilizer burn and the plant will turn brown. Which is responsible for the death of your plant.

Look very closely at the plant’s root; if you see any unabsorbed fertilizer, the issue was most likely caused by excessive fertilizer application.

Fixing Guide

Brunnera typically doesn’t require a lot of fertilizer. Applying organic materials and organic compost is recommended.

By using eggshells, tea leaves, animal dung, curry leaves, cardboard, discarded newspapers etc you can make good quality organic compost at your home. It takes a maximum of one to two weeks to make it.

However, you can use a little fertilizer during the growing season. Nitrogen-rich fertilizers can be a good choice. If plants exhibit chlorosis, liquid iron fertilizer should be sprayed on them.

6. High Temperature and Humidity

Excess temperature and humidity create a stressful environment for your Brunera plant. If the temperature in your area is too high, the plant can not operate its own biological functions properly.  

The same problem occurs when the humidity increases. Excess moss prevents plants from absorbing the carbon dioxide they need. As a result, the tree dies quickly.

Fixing Guide

In general, brunnera prefers cool temperatures. The best temperature range is 60° to 70°F. Although they may thrive in temperatures between 55°F and 60°F, they even grow more frequently at 65°F. To keep the temperature at its ideal level, you can utilize an automatic temperature controller device.

However, it struggles in environments with heavy humidity and does best in hardiness zones 3 to 8. This issue can be permanently fixed with a humidifier.

I suggest you plant it in a garden that receives some shade, preferably in a warm environment.

7. Pruning Mistake

Even pruning mistakes can be responsible for the dying symptoms of your Brunera plant. Unnecessary pruning at the wrong time is harmful to any plant.

When you do unnecessary pruning on your plant, most of the time it loses its important branches. Many beginners in particular tend to prune the roots of plants during replanting. 

As a result, the plant loses its necessary organs and fails to perform its normal chemical functions. Roots cannot collect the necessary water and nutrients from the soil. Gradually the tree withers and dies.

Fixing Guide

Brunera plants generally do not require much pruning. But in summer you can cut the old leaves of the plant to make space for new leaves. Besides, the plant needs to be deadheaded at the end of the flowering season.

But never over-retrenchment. Keep in mind that extra leaves protect the plant’s crown in winter so winter pruning is not necessary.

During replanting, you can cut off the unnecessary part of the roots. But care should be taken not to cut any branches. Equipment should be thoroughly disinfected before pruning.

Frequently Asked Questions (FAQs)

Can You Grow Brunnera As A Houseplant?

Yes. Brunera plants can be grown both indoors and outdoors. But it is better to grow it indoors after planting the seeds. In both cases almost the same care is required.

Why Are My Brunnera Leaves Turning Brown?

There are a number of reasons why the leaves of your Brunera plant may turn brown. However, poor-quality soil, excessive sun exposure, insufficient watering, excessive fertilizer application, and some insect and fungal attacks are the most damaging to Brunera leaves. However, if proper measures are taken in time, the tree can be fixed quickly.

Should I Fertilise Brunnera?

The growth of brunnera plants requires little fertilizer. When planting, add high-quality organic compost to the soil. Later, fertilizer containing that nutrient can be used to treat specific nutrient deficiencies.

The Final Word

Caring for Brunnera plants is quite easy, but the slightest deviation can cause the plant to show dying symptoms. So you have to be very aware of the main causes. Once you can identify the cause there should be no problem fixing the plant.

Hope my discussion has given you a complete guide on all Brunnera plant problems and solutions. Happy Gardening.
