How to Plant, Grow, and Care for Lemon Cucumbers

Bright yellow ‘Lemon’ cucumbers are a great option if you want to step away from classic green cucumbers. Join farmer Briana Yablonski to learn how to care for these unique, round cucumbers.

The first time you see a ‘Lemon’ cucumber, it’s....

hard to believe it’s even a cucumber plant! While it has the classic cucumber vines and leaves, the fruits resemble small yellow baseballs rather than the elongated green cucumbers you’re probably familiar with. However, when you bite into the crunchy and sweet cukes, you’ll recognize that ‘Lemon’ cucumbers aren’t so different than their green counterparts.

I first saw these yellow cukes when working at a vegetable farm in Virginia. Once farmers’ market customers became familiar with them, they became big fans. The yellow skin mixed nicely with green cucumbers in salads and sandwiches, and their small size made them easy to use.

Out in the fields, ‘Lemon’ cucumbers grew similarly to other types of cukes. They thrived during sunny and warm days as long as they received plenty of water, and sent out new ripe cukes every few days. I’ll share basic information as well as tips and tricks to help you grow these interesting cucumbers in your garden.
What Is It?
The ‘Lemon’ cucumber is an annual vining plant best known for its round, yellow fruits. Although these fruits look different from other types of cucumbers, they come with the juicy, sweet crunch cucumbers are known for. They don’t taste like lemons; instead, they get their name from their appearance.

Characteristics
Like all cucumbers, ‘Lemon’ cucumbers are cold-sensitive annual plants. They grow in a sprawling habit with multiple herbaceous vines covered with scratchy green leaves. The vines also produce curling tendrils that the plant uses to wrap around and climb up objects like fences and arbors.

About two months after planting, the plants produce small, yellow flowers. Each plant is monoecious, meaning it produces both male and female flowers. The female flowers have the potential to become fruits, while the male flowers supply pollen.

The real defining characteristic of this plant is its round, yellow fruits that are a little smaller than a tennis ball. These cucumbers have a thin skin and sweet, burpless flesh. If all conditions are right, ‘Lemon’ cucumber plants begin producing mature cucumbers about 65 days after you plant the seeds.

Native Area
Cucumber plants are native to tropical areas in Southeast Asia. Many people report that the ‘Lemon’ cucumber was popular in Australia before it made its way to the United States in the late 1800s.

Planting
‘Lemon’ cucumbers are warm-weather crops that grow best in the summer months. You can grow them by direct sowing seeds or planting transplants, and if you live in an area with a long growing season, you can plant multiple successions each year.
How to Grow
‘Lemon’ cucumbers are moderately easy to grow, provided that you grow them in the right conditions. While their care requirements aren’t difficult to fulfill, they are susceptible to various diseases and pests. As long as you keep your plants healthy, you’ll enjoy a large and prolonged harvest.
Maintenance

‘Lemon’ cucumber plants can be as low maintenance or high maintenance as you like. I’ve let the plants sprawl across the ground with no help from me besides watering. However, you can also trellis and prune your plants if you’d like.

Trellising and pruning help improve airflow, limiting the likelihood that the plants will develop disease. It also frees up space in your garden for other crops to grow. If you’d like to trellis your ‘Lemon’ cucumbers, start when the plants are young. It’s easier to train small plants to grow up a trellis rather than wrangle large plants later on.

Numerous methods and materials work well as a trellis. You can use a single vertical string and clip the vine to the string. If you utilize this method, prune off any vines that grow off the main stem. Another option is to guide the plant to grow up a metal cattle panel. The plant’s tendrils will wrap around the wire and support the plant.

Outside of trellising, ‘Lemon’ cucumber plants require little maintenance. If you see any diseased or discolored leaves, you can prune them off and dispose of them. This will slow the spread of disease to other parts of the plant.
