The rose bush is often regarded as a beautiful, ever-blooming, and indestructible plant.
Despite its harsh appearance, it is really rather delicate.
Are your rose leaves, for example, turning yellow? A lot of things might be going on.
A little alteration in its setting, unwelcome interaction with other creatures, or simply a seasonal shift in your garden might transform it from lovely to scarcely perceptible.
While there are plenty of explanations, it’s more difficult when you’re really stumped. You don’t have to guess, thankfully.
We figured out why this occurs, how to spot the issue, and how to remedy it. Check out all of the reasons and solutions listed below!

What Causes Rose Leaves to Turn Yellow?
1. Excessive watering
The most typical reason a rose plant begins to yellow is when there is too much dampness. This is also referred to as saturation.
The roots will sink in saturated soil. Your plant will gradually deteriorate if oxygen cannot reach the roots due to an abundance of water.
How to Tell if a Rose Is Overwatered:
- To begin, determine how wet the soil is. It’s possible that your plant is waterlogged if it feels damp or muddy.
- In certain circumstances, the dirt on top seems to be dry, but the soil below (where the roots are) is not. To see whether that’s the case, you’ll have to delve a little further.
- In certain circumstances, this occurs as a result of excessive rainfall or irrigation. A rose may live for a week without being watered.
- Finally, it’s possible that it’s occurring because the soil contains too much water for the rose or there isn’t enough drainage.
How to Rehydrate a Rose That Has Been Overwatered:
- Transplanting an overwatered rose is the best remedy. Garden beds with clay-free soils are frequently the most successful.
- If you’re growing roses in plastic pots, poke holes in the bottom to allow water to drain.
- You may bring your rose inside or under a cover if it is getting too much water from rain.
- It’s also possible that you’re overwatering. Only water the rose once a week to cure this (especially in winter or humid areas).
You should notice effects within a month if there is an improvement. Be mindful that excessive watering might lead to decay (this is more difficult to fix).
While overwatering your rose may drown the roots, not watering it enough will starve them.
The first symptom that a plant is malnourished is yellowing of the leaves and stem. The plant becomes feeble as a result of the lack of nutrients received via the roots.
How to Look for a Rose That Has Been Underwatered:
- Examine the soil to determine whether it is sandy or overly stiff. This indicates that it is not keeping sufficient moisture.
- The quantity of soil is also critical. Roses that are grown in too little soil (and hence with too few nutrients) are prone to wilting (especially in warm climates).
- Sunlight may also dry out the soil more quickly by draining humidity and preventing roots from absorbing nutrients.
- Insufficient irrigation or a lack of rainfall might also be to blame. Watering your rose at least once a week is recommended.
How to Rehydrate a Rose That Has Been Underwatered:
- A moisture-retaining substance added to the soil might be a great solution. Mulch, compost, and clay, for example, may all help retain moisture.
- Ascertain that the rose has enough soil. Transplant to a richer soil or a bigger container if the roots are visible or the plant seems to be too big for the container/space.
- Using an automated sprinkler or soaker hose system to water the plant without any output might be beneficial. Just make sure it occurs at least once a week.
It may take up to a week or two for this procedure to show evidence of improvement.
3. Excessive Fertilizer
Plants thrive in surroundings that are nutrient-dense. They may, however, suffer if there are more nutrients than they can chew.
Excess of a nutrient is usually the cause. The problem is usually caused by an overabundance of iron or nitrogen.
How to Tell if You’re Feeding a Rose Too Much:
- Check the fertilizer package if you recently fertilized the rose. Some general-purpose fertilizers include much too much nitrogen and iron for roses, causing the rose to burn.
- Compost and other soil additives may potentially be problematic. It’s also possible that you jumbled some of those up lately.
How to Rejuvenate a Rose That Has Been Overfed:
- Transplanting to a more neutral fertilizer-free soil might be a terrific option if you recently applied fertilizer or any other item.
- To avoid this from occurring again, just use rose fertilizer. Any combination that has a lot of iron or nitrogen should be avoided. Instead, stick to high-phosphorus combinations.
- If the leaves and stems are drooping, prune them. After that, give the rose plenty of water to ensure it recovers.
When you stop overfeeding them, Rose will improve fairly immediately, within a few days.
4. Inadequate Fertilizer
Similarly to not eating because the soil is too dry or too wet, sometimes it just lacks the necessary nutrients.
When there is a deficiency in nitrogen, magnesium, iron, or, more crucially, phosphorous, this occurs.
How to Tell if You’re Feeding a Rose Too Little:
- Sandy soils (regardless of how wet they are) are often indicative of nutrient deficiency. Roses appreciate soils that are dark and nutrient-rich.
- It’s also possible that the plant isn’t getting enough water and isn’t getting enough nutrients from the soil. Make it a point to water your plants at least once a week.
- This is also a likely reason if you haven’t fertilized in over a year. This is especially true in arid places, where soil minerals decrease more quickly.
How to Rejuvenate an Underfed Rose
- The most efficient solution is to immediately begin fertilizing the rose. You may adjust the soil by immediately applying a layer of mulch, compost, manure, and a rose fertilizer.
- You may wish to completely transplant the rose in sandy or dry soils. To avoid this, keep it on well-manured, nutrient-rich soils.
- Remember to water the rose once a week and fertilize it at least once every six months.
Weeks will pass before you see any improvement in the rose plant.
5. Unhealthy Soil Make-Up
The rose will begin to wither if the soil does not meet the plant’s needs.
This might be due to the fact that it is not absorbing enough nutrients or that there aren’t enough nutrients to absorb.
If the leaves turn yellow but the stems remain brilliant green, the soil is unhealthy. This is most likely the source of excessive pH levels.
How to Check for Rose in an Unhealthy Soil:
- A soil pH tester may be used to monitor pH levels. It must be less than 6.5 but not less than 6.0.
- Consult your neighbors or local experts to see whether the soil at your house is too alkaline or acidic for your plants.
How to Restore a Rose’s Health in Unhealthy Soil:
- The best treatment for soils that are too alkaline (pH more than 6.5) or too acidic (pH less than 6.0) is to transplant to neutral soil. Before transplanting, prepare the soil and inspect it.
- Sulfur and aluminum sulfate may also be used to treat alkaline soils. To be sure, check the pH levels.
- Magnesium-rich fertilizers or crushed limestone may be added to acidic soils when plants are unable to absorb nutrients. To be sure, recheck the pH.
Those who want to transplant the rose should expect to see effects in a few weeks. It might take up to a month for amended soils to show benefits.
6. Excessive Sunlight
It is fairly unusual to observe plants that have been burnt by the sun. It’s possible that your rose plant may become a victim.
This is more common in tropical climates particularly throughout the summer. It’s not unusual for the rose to wilt from the added heat when the sun is at its zenith.
How to Tell if a Rose Has Been Scorched:
- The yellow is a deeper, almost brownish yellow, not a bright yellow. If you see a deeper tone on the leaf, it’s a symptom of too much sunshine.
- Scorched leaves are those that become yellow and crisp at the same time. Look for branches and stems that turn yellow when exposed to the light.
- In the summer, roses that are directly in the sun and get more than 6 hours of sunshine every day may also experience this.
How to Restore a Burned Rose:
- Taking the rose to a more shady location is the best option. It should be OK somewhere that receives no more than 4 hours of sunshine every day.
- Prune burnt leaves that have become brown and crispy rather than yellow. This should help to promote the development of new, healthy leaves.
It will take some time for your rose to improve, but it shouldn’t take more than a month.
7. There’s Too Much Shade
Too much sunshine will burn the leaves, while too little will make them wilt.
The leaves not only wither but also fall as a result of this. Most of them begin to droop and soften till they drop.
By the way, the leaves towards the bottom of the plant are more likely to be affected than those at the top.
How to Tell if a Rose Is Shaded:
- Examine if the plant is protected by a roof or is shaded by bigger plants. This is usually the case.
- Check to see whether the leaves at the bottom are the ones that are yellowing. This is typical and shouldn’t give the plant any problems.
How to Rejuvenate a Shaded Rose:
- Move the rose to a more sunny location. If the plant is in a pot, relocate it to that sunny spot instead.
- Another apparent solution is to cut or prune other plants that are generating the shadow.
- If the plant’s bottom leaves are fading, prune it. This might explain why the vegetation on top is denser, forcing the foliage below to wither.
Within a few weeks, as long as the rose gets at least 6 hours of sunshine every day, it should begin to recover.
8. The Influence of Temperature
Rose bushes suffer when temperatures aren’t optimal, in addition to getting too much or too little sunshine.
Heat stress, for example, causes the leaves to dry up and fall. When temperatures drop too low in the winter, leaves, like most other plants, fall.
How to Tell if a Rose Is Temperature-Stressed:
- Seasonal changes are often to blame. Yellowing is a common phenomenon in the summer when temperatures are increasing, or in the winter when frosts have begun to form.
- Examine if the rose is too near to heat-generating items such as air conditioner condensers, kitchens, heaters, or even ovens.
- Roses that are grown inside and are exposed to air conditioners may turn yellow as a result of the cold. Although it’s uncommon, direct contact with AC airflow might be the cause.
How to Care for a Rose That Has Been Stressed by the Heat:
- The best thing to do as the seasons change is to maintain the rose in a cooler or hotter environment as required. If feasible, bring the rose inside throughout the winter.
- In warmer climates, adding mulch to the soil may also assist to keep the plant fresh. Watering more often (but not excessively) may also help.
Be warned that seasonal yellowing is common, and you may not be able to prevent it. Otherwise, you’ll see benefits in a matter of weeks.
Pests and critters (number 9)
Many animals may be gnawing on your rose, causing havoc. Spider mites, leafhoppers, grasshoppers, and even ants are among these pests.
It’s not only insects, however. Some animals, such as gophers, skunks, deer, rabbits, goats, and even pigs, may create havoc.
How to Look for Pests and Critters That Affect Roses:
- Check the plant for pests by looking for critters on the leaves, stems, and branches. If you observe insects or their eggs, it’s possible that your plant is infested with pests.
- If you’re looking for creatures, look for bite marks or ripped-away branches. This indicates that your plant is being eaten away at, perhaps weakening it and causing yellowing leaves.
How to Restore a Rose That Has Been Affected by Pests and Critters:
- Pesticides are the most effective technique to get rid of insects. Pesticide soap, neem oil, chili pepper spray, garlic spray, and even vinegar may assist. Use products designed for the pests you’re trying to get rid of.
- Spicy odors like pepper and cayenne pepper may deter creatures. Ammonia and vinegar may also be beneficial. If everything else fails, utilize visual or acoustic repellents.
- You might choose to clip off any broken leaves or branches. This should encourage fresh, healthy development.
This sort of injury usually improves very immediately. However, you must maintain the plant clear of pests and away from creatures.
10. Fungi and Diseases
Roses may seem sturdy, but they are susceptible to illness.
Some of them may acquire serious illnesses such as black spot or mosaic disease. Leaves become yellow, acquire black blotches, and finally fall off when this happens.
The whole rose plant may wither and die if not addressed. As a result, it’s critical to detect and resolve the issue before it’s too late.
How to Examine a Sick Rose
- Check to see whether the leaves are becoming light green or yellowish with little dots. This is a symptom of ring or mosaic illness.
- A indication of black spot is when some leaves become yellow while others turn brown to dark brown.
How to Rejuvenate a Sick Rose:
- Rake fallen leaves off the underside of the house. If feasible, prune the afflicted leaves, branches, and stems. None of this should be composted. They should be burned or discarded soon away.
- If your rose bushes are still salvageable (just a few leaves/branches are harmed), you may apply a fungicide as a possible treatment. Following the directions on a rose fungicide should help.
- Move the rose shrub to a light-filled area. It should have enough air circulation to prevent the sickness from spreading too quickly.
- Allow no moisture to accumulate on the leaves. This often results in the growth of additional fungus, which finally leads to illness. When watering, make direct contact with the soil.
Within a few weeks, if the condition hasn’t progressed too far, you should observe beneficial results. It might take up to two months for the plant to recover if it was seriously harmed.
