This is probably the most common problem in the gardening world, yellowing leaves. There are 2 main reasons for this phenomenon, overwatering, or a lack of nutrients.
When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:
Here are some indicators of yellowing on the Rosa rugosa 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.
- The newest leaves are first affected by sulfur deficiency, rendering them completely 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.
- Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.
You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.
Is my Rugosa rose sunburned?
It is simple to determine whether your Rugosa rose (your Rosa rugosa) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
As we saw above, if your Rugosa rose receives too much water or not enough light, the leaves may also change color.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.

Why are my Rosa rugosa leaves drooping or wilting ?
This typically occurs when your Rosa rugosa gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Rosa rugosa plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the Rugosa rose after a dry period in the belief that it requires 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 Rosa rugosa
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 Rosa rugosa.
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
Maintaining a consistent temperature for your Rosa rugosa is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Rosa rugosa close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Rugosa rose Dust-Free
This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.
This would be a true journey into hell for your Rugosa rose and would also satisfy the pests.
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 have a tendency to overwater, you should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.
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!)
