Cucumber Questions Answered
Views: 9

Cucumbers are one of the easiest vegetables I have grown. They grow quickly and give you plenty to harvest for the effort you put in, and that is super rewarding. If you’re planting a garden or potting up a few vegetable containers for the patio, you should definitely consider cucumbers.
You may have questions about growing cucumbers if you’ve never grown them before. We have answers! I’ve answered five common questions you may have if you are new to cucumbers.
1. When is the best time to plant cucumbers?
Cucumbers thrive in warm weather just like tomatoes and peppers. Have patience! Wait until all danger of frost has passed and soil temperatures reach at least 65–70°F before planting outdoors. The Old Farmer’s Almanac has a tool that lets you find your last frost by zip code. Cold, damp soil can slow growth or damage seedlings. While you can start seeds indoors about 3–4 weeks before your last frost date, many gardeners prefer direct sowing since cucumbers don’t like their roots disturbed. If transplanting, use biodegradable pots and harden plants off gradually.
2. Can cucumbers grow in containers or small spaces?
Yes! But you need to pay attention to what variety you plant. For instance, bush varieties (as opposed to vining) are ideal for containers, staying compact while still producing plenty of fruit. Vining types can also be grown in small spaces if trained vertically on a trellis or support. Plant in a container at least 12 inches wide with good drainage, and place it in a sunny location. With the right setup, even a small patio can yield a steady supply of cucumbers.
3. How much water and fertilizer do cucumbers need?
Considering that cucumbers are more than 90% water, consistent moisture is critical in order to grow a good crop. Aim for about 1 inch of water per week, more if it is super hot or dry. Water deeply—meaning, allow the water to really soak into the soil, which encourages roots to grow down to look for it. This leads to a strong root system. Adding a layer of much on top will help retain moisture and keep soil temperature even. Because cucumbers are heavy feeders, you’ll do well by adding compost before planting and apply a balanced fertilizer every couple of weeks once vines begin to grow.
4. Why are my cucumbers bitter or misshapen?
Most fruit quality issues are caused by stressors in the environment. Those could be inconsistent watering, higher temperatures, poor soil fertility, or inadequate pollination. All of these factors could result in a bitter flavor or oddly shaped cucumbers. The solution? Maintain even moisture, feed regularly, and encouraging pollinators to visit. In fact, if you notice low bee activity, you can pollinator your cucumber flowers by hand.
5. Do cucumbers need a trellis?
Technically no, but you and your cucumber plants both benefit with some sort of supports for their growing vines. Lifting those vines, leaves and developing fruits off the ground can:
- improve air circulation
- reduce disease
- keep fruits clean
- make harvesting easier
- maximize space
I’ve heard that trellises may also allow pollinators easier access to the flowers. All of the above are great reasons to install a trellis. Do so early in the plant’s growth and gently guide vines upward as they grow.
And remember, you only need a few plants. Otherwise, you’ll have cucumbers growing out of your ears.
