NOTE: The terms Gold Mound spirea and Spiraea japonica ‘Gold Mound’ are identical in this text; in reality, Spiraea japonica ‘Gold Mound’ is Gold Mound spirea’s biological word.
Gold Mound spirea has bright golden ovate leaves in the spring, which turn a brilliant yellow in the fall. It has clusters of bright pink flowers in late spring and summer which attract butterflies.
Other shrubs produce flowers and foliage that is more striking in the fall, but this one thrives in the spring. It is less exciting when the color changes to a golden green. The shrub’s fall foliage is yellow and red, and it makes a comeback in October.

Why are my Gold Mound spirea leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:
Here are some indicators of yellowing on the Spiraea japonica ‘Gold Mound’ brought on by its numerous flaws:
- Magnesium deficiency starts as yellow patches between leaf veins on older leaves. Veins stay green as yellow moves from the leaf center out. Leaf edges turn yellow last.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur shortage first affects the youngest leaves, turning them entirely yellow.
- Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown.
- A lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.
Our Solution
You only need to respond to the signs mentioned above. A gardening store expert will be able to provide you advice on how to purchase a specific soil to treat a potassium or nitrogen deficiency. Additionally, you can reduce how often you water your plants.
Is my Gold Mound spirea sunburned?
It is simple to determine whether your Gold Mound spirea (your Spiraea japonica ‘Gold Mound’) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
The leaves of your Gold Mound spirea can also change color in case it gets too much water or not enough light, as we saw above.
However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.
Why are my Gold Mound spirea leaves turning brown?
A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.
Should I leave my Spiraea japonica ‘Gold Mound’ in direct sunlight?
No! Don’t leave your Spiraea japonica ‘Gold Mound’ (or Gold Mound spirea) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
Our Solution
As explained in the paragraph above, the solution is simple, just place your Gold Mound spirea in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Spiraea japonica ‘Gold Mound’ leaves drooping or wilting ?
When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.
You may quickly determine if your Spiraea japonica ‘Gold Mound’ plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
Our Solution
If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the Gold Mound spirea right away after a dry time because you think it needs a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Spiraea japonica ‘Gold Mound’
Water Occasionally
Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Spiraea japonica ‘Gold Mound’.
The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.
Always keep temperatures stable
It is also a good idea to keep your Spiraea japonica ‘Gold Mound’ at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Spiraea japonica ‘Gold Mound’ near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Gold Mound spirea Dust-Free
This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.
This would also make the pests happy, a real descent into hell for your Gold Mound spirea.
To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like rubbing alcohol!
Keep drainage in mind
If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.
In the meantime, if you don’t have holes in your pots, you can add volcanic rocks (or any rocks with holes) at the bottom of your pot, this way it will create a channel so that the water doesn’t stay in your skin too much (to avoid that roots start to rot!)
