7 Proven Reasons Why Are My Cucumbers Curling?

Growing cucumbers can be a rewarding experience, but sometimes your cucumber plants may end up producing curvy or curly cucumber seeds. If you’re wondering why your cucumbers are curling instead of growing straight, here are 7 common reasons for Cucumbers Curling that could explain it.

Physical Interference

Physical interference is one of the main reasons why cucumbers are not growing straight. Too much handling or walking too close to the cucumber plants can cause them to curl and become distorted. 

Also, strong winds can cause the stems to bend and twist, which can cause the cucumber to grow crooked. 


To avoid this, be sure to provide protection from the wind and handle your cucumbers with care.

Poor Nutrition

Nutrition plays a major role in the growth of cucumbers. If the soil lacks essential nutrients, such as nitrogen, phosphorus, and potassium, it can lead to curled cucumbers. Ensuring adequate levels of nutrition will help ensure straight cucumbers. 


Make sure to use high-quality fertilizer that is specifically made for cucumbers. Regularly test soil for nutrient levels and supplement as needed.

Pests & Diseases

cucumbers pests and disease

Incorrectly grown cucumbers can attract many pests, including aphids, squash bugs, cucumber beetles, and whiteflies. These pests can feed on leaves and flowers, leading to reduced yields and curling of the cucumber vines. 

Diseases like powdery mildew, Fusarium wilt, and Cucumber Mosaic Virus can also cause cucumber leaves to curl and stunt the growth of the plants. 


To prevent this, you should use a balanced fertilizer, water regularly, and check for pests regularly.

Incorrect Pollination

If cucumbers aren’t pollinated correctly, their shape can be affected and they become cucumbers curling. This can be due to a lack of bees, wind, or other pollinators. If the flowers are not open at the same time or are too far away from each other, pollination will be incomplete. 


To ensure successful pollination, hand-pollinate with a paintbrush or spray water on the flowers.

Lack of Water

Cucumbers need consistent moisture to grow straight, so insufficient watering can cause them to curl. If the soil is dry and cracked, it’s a good indication that your cucumbers are not getting enough water. 


Watering your cucumbers deeply and regularly can help them to grow straight again.

Too Much Fertilizer

If your cucumber plants have received too much fertilizer, the leaves and stems can become weak and curl as a result. Over-fertilizing can also cause salt and mineral buildup in the soil that can cause the cucumber vines to curl. 


To avoid this issue, be sure to use the right amount of fertilizer and water regularly to flush out any excess nutrients.

Poor Soil Drainage

Cucumbers need well-draining soil to grow straight. If soil is not draining properly, cucumbers can start to curl or bend as a result of too much water in the root zone. Compacted soil, excessive clay, and heavy soils can all cause poor drainage. 


Make sure your soil is loose, has proper aeration, and drains quickly for better cucumber growth.
