Once I tried to propagate rose from cuttings and I saw my rose cuttings growing leaves but not roots. So I asked my friend and she said it’s not uncommon. Some of the issues involve insufficient hormones, improper soil moisture, low humidity, disease, overfertilization, etc.
It can happen because of hormones, improper soil moisture, low humidity, disease, overfertilization, and so on. Well, if you are planning to grow rose plants from cutting, please keep reading. Here, you’ll find something essential that will make your effort successful.
How Long It Takes for Rose Cuttings to Grow Roots?
The time it takes for rose cuttings to develop roots varies, typically ranging from 4 to 8 weeks. Factors influencing this timeline include the rose variety, environmental conditions, and the type of cutting (softwood or hardwood).
More likely, you will see softwood rose cuttings to root faster than hardwood ones. Maintaining consistent moisture and humidity levels, along with providing an optimal temperature between 65-75°F (18-24°C), accelerates root growth.
Using a rooting hormone aids in quicker development. Patience is key; some roses might establish roots sooner, while others might take longer. Regular monitoring is essential, gently tugging the cutting after a few weeks to feel for resistance, indicating root formation.
Once roots are about an inch long, the cutting can be transplanted to a larger pot or the garden. Overall, expect a span of 1.5 to 3 months for rose cuttings to grow roots and become viable plants.
Reasons Why My Rose Cuttings Have Leaves But No Roots?
Here are more reasons why your rose cuttings growing leaves but not roots, along with additional explanations:
Root Zone Temperature
Roses generally require warm soil temperatures for root development. If the root zone isn’t warm enough, it can hinder root growth even if the plant has enough stored carbohydrates. Using a heating mat or placing the cuttings in a warm location can help promote root growth.
Stored Carbohydrates
While stored carbohydrates are essential for initial growth, having enough stored energy might not be sufficient for root development. Roots require a steady supply of nutrients to grow, and a balance between carbohydrate availability and nutrient uptake is crucial.
Low Humidity
Roses thrive in humid environments, especially during the rooting phase. Low humidity levels can lead to excessive moisture loss through the leaves, which can stress the cutting and prevent root development. Consider using a humidity dome or misting the cuttings roses regularly to maintain proper humidity levels.
Moisture Management
Keeping the cuttings too dry or too wet can both hinder root growth. If the cuttings roses dry out, they can’t take up water and nutrients. On the other hand, overly wet conditions can lead to fungal issues and root rot. It’s important to find the right balance by ensuring the growing medium is consistently moist but not waterlogged.
Fungal Infections
Fungal infections can occur if the cuttings are kept in high humidity and damp conditions without proper air circulation. Also, fungi can attack the stem and hinder root development. To prevent fungal infections, provide good ventilation and ensure the leaves don’t stay wet for prolonged periods.
Cutting Quality
The quality of the cutting itself can influence its ability to develop roots. Choose healthy, disease-free stems for propagation. A cutting with any existing diseases or damage might struggle to develop roots even if it produces leaves.
Rooting Hormones
Using rooting hormones can greatly enhance the chances of successful root development. These hormones stimulate root growth and increase the cutting’s ability to produce roots.
Rooting Medium
The medium in which you’re trying to root the cuttings matters. A well-draining medium with good aeration is important for root development. A heavy or compacted medium can impede the growth of new roots.
Light Levels
While light is essential for photosynthesis and leaf growth, excessive light can stress the cuttings and divert energy away from root development. Moreover, providing adequate but not excessive light is crucial during the initial stages of propagation.
Patience
Root development can take time. Some rose varieties might require longer periods to develop roots than others. Patience is key, as premature attempts to transplant cuttings with leaves but no roots can damage the developing root system.
To improve your success with rose cutting propagation, focus on maintaining optimal conditions for root development, including proper temperature, humidity, moisture levels, and hygiene practices. Experimenting with different rose varieties and adjusting your approach based on their specific needs can also lead to better results.

How to Treat Rose Cuttings That Have Leaves But No Roots
Treating rose cuttings that have leaves but no roots requires addressing potential issues that might be hindering root development. Here’s a step-by-step approach to help you:
Step 1: Assessment
Examine the cuttings roses in potato closely to rule out any visible problems like diseases or physical damage.
Step 2: Rooting Hormone
If you didn’t use rooting hormone initially, dip the cut ends of the rose cuttings in a rooting hormone powder or gel. This helps stimulate root growth.
Step 3: Check Moisture
Ensure that the soil or rooting medium is consistently moist but not waterlogged. Inadequate or excessive moisture can affect root development. Mist the leaves occasionally to maintain humidity around the cuttings.
Step 4: Humidity Dome
If humidity is low, create a makeshift humidity dome using a clear plastic bag or a transparent container to trap moisture around the cuttings. This encourages root development.
Step 5: Temperature Control
Maintain a stable temperature within the recommended range for rooting rose cuttings to root (usually around 65-75°F or 18-24°C). Extreme temperatures can impede root growth.
Step 6: Rooting Medium
Check that you’re using a well-draining, sterile rooting medium that provides aeration to the cuttings’ base. Adjust the medium if needed.
Step 7: Time and Patience
Remember that root development takes time. Be patient and continue to care for the cuttings, even if it takes several weeks.
Step 8: Inspect Cutting Type
If you use hardwood cuttings, they might naturally take longer to root. Research the specific rose variety you’re propagating to understand its typical rooting timeline.
Step 9: Avoid Overfertilization
Discontinue or reduce fertilization during the rooting process, as excessive nutrients can inhibit root growth.
Step 10: Sanitation
Ensure cleanliness in your tools and planting environment to prevent diseases from affecting the cuttings.
