How Much Sun Do Cucumbers Need?

Cucumbers are a warm-season vegetable that grows best in the summer months. They need a lot of water and plenty of sun as well. To keep them growing and producing vegetables, you may wonder how much sun cucumbers will need.

How Much Sun Do Cucumbers Need?

The answer to this question depends on where you live and the variety of cucumbers you’re growing. Generally, cucumbers need at least 6 hours of sun a day to grow well. Cucumbers grown in containers may need more sunlight than those grown in the ground.

In general, more sun means more fruit. However, too much sun can cause scorching on the leaves and fruit splitting. The best time for planting cucumbers is when temperatures are above 60 degrees F and soil temperatures are above 60 degrees F.

Do Cucumbers Prefer Full Sun?

Cucumbers are a warm-weather crop that needs full sun to grow well. They are able to tolerate partial shade, but they will not produce as many cucumbers as they would in full sun. In fact, if you want a large harvest of cucumbers, your best bet is to plant them in a sunny area of your garden.

Cucumber plants can be grown on trellises or other supports so that they do not shade each other. This allows the plants to receive maximum sun exposure without crowding each other out. If you have an area where you can provide support for the cucumbers and give them enough room to grow, then it makes sense to plant them there.

Where Does Cucumbers Grow Best?

The best place to plant cucumbers is in raised beds or containers that have been filled with rich composted soil. You can also grow them in large pots on a patio or balcony indoors if it gets at least six hours of direct sunlight per day.

Plant cucumber seeds about 1/4 inch deep and about 12 inches apart from each other in rows that are 2 feet apart from each other. If you’re growing them outdoors, make sure you place them at least 3 feet away from any other plants so they don’t compete for nutrients and water from the soil around them.

Besides the sun, cucumbers will need to be watered often. They need a lot of water since cucumber is made up of 96% water.

Can Cucumbers Get Too Much Sun?

Cucumbers are a warm-weather crop and grow best in full sun. They can tolerate partial shade, but the plants may not be as productive and the fruit will be smaller.

Cucumbers don’t like heat, however. The ideal temperature for cucumber growth is between 70°F and 75°F (21°C and 23°C). If it gets hotter than that, you risk damaging the plants, which can result in poor fruit production or even death.

If your cucumbers are getting too much sun because of your location or weather conditions, you may need to adjust your plantings so they get less sunlight each day. This will help them produce better-quality fruit.

Signs Your Cucumbers Don’t Get Enough Sun

Cucumbers need plenty of sunlight to grow properly, so if you want a healthy crop this year, you should pay attention to these signs that your cucumbers don’t get enough sun:

  • The leaves are dark green or yellowish-green
  • The plant has a strong odor
  • The leaves have large brown spots or blotches on them
  • The fruit is small and misshapen

Your cucumber plants may not get enough sun if you planted them too close together or if there isn’t enough space between rows for sunlight to reach the plants. It’s also possible that your cucumbers were damaged by high winds or hail during the growing season — even just one hard hit can cause damage that affects growth later on in the season!


Most varieties of cucumber need at least six hours of direct sunlight each day to produce good fruit. If your cucumbers are not producing well, check to see how many hours of direct sunlight they are getting each day. If you live in an area that gets a lot of cloud cover during the day, it may be hard for your plants to get the amount of light they need for good production.
