Care & Harvest

🌡️ Temperature

Cucumbers thrive in temperatures ranging from 70-85°F.

✂️ Pruning

It’s essential to prune cucumbers. Remove the initial 5 flowers from the bottom and trim any extra flowers to ensure the plant doesn’t have more than 5 cucumbers. Overcrowding can lead to young fruits discoloring and withering before they fully develop. Cut the primary stem to your preferred height, promoting side branches to sprout. This makes the plant denser and ensures it remains within the light range of your Gardyn. Regularly inspect the roots and cut any that appear brown or protrude beyond the yPod.

🔎 Plant Health

Thrips can be a nuisance, but with our preventive measures and treatment methods, you can keep them at a distance. Cucumbers flourish when provided with fresh water and consume a significant amount as they grow. Ensure the water level remains above 60% and replenish it every week to promote optimal growth.

🥬 Harvest

Pluck cucumbers when they measure between 3-4 inches, exhibit a deep green hue, and once the yellow flower detaches from their end. Sever the fruit from their individual stems. Overripe cucumbers might develop a bitter taste. Also, be mindful of the tiny spikes on cucumbers; you can gently brush these off post-harvest.

What Do You Need To Grow Cucumber At Home?

With a bit of patience, cucumbers can be incredibly easy and rewarding to grow. Perfect for the aspiring gardener, this tropical fruit loves hot and humid climates, and will thank you for plenty of water.

Light

Cucumber plants are what’s known as “day-neutral”, which means that they take light from just about any time of day. In any case, they still require plenty. Make sure to give your cucumbers at least 8 hours of full sun daily (or 14 hours under full spectrum grow lights).

Temperature

Cucumbers thrive in warm weather — think 65–75°F. Frost is a big no-no; temperatures as low as 55°F can start to affect the quality of your fruit. Keep them away from any strong winds or cool drafts. Use cloches or frost blankets to safeguard your young plants against the occasional danger of chilly weather.

Container

To grow cucumbers at home, you need to use the right container. Plastic or ceramic is ideal as these materials help to maintain moisture. Make sure your container includes sufficient drainage, too! If you’ve got space, opt for a 20-inch pot, which will be big enough for two to three plants. You can also go smaller with a 12-inch planter that fits two plants, or a 7-10-inch planter for one cucumber plant.

Growing Medium

Your growing medium should be light and well-draining, while allowing for good air circulation to the plant’s roots (important to protect against diseases like powdery mildew). Try a combination of high-quality potting soil, pumice, and perlite. This will give your cucumbers all the room they need to flourish. Keep soil pH between 6.0 and 6.5 for optimal yields.

Important: Avoid using garden soil, which is too heavy and compact for container gardening. It may also bring in pests like cucumber beetles, as well as various diseases — things you certainly do not want in your indoor vegetable garden.

Cucumber Types and Varieties

Cucumbers can either be vining or bush. Vining plants can reach up to six feet long, making them tricky to cultivate in the house. Bush types, on the other hand, are much more manageable indoors. With their short vines and round compact shape, they fit nicely into containers or pots. Even better, they don’t require support for their fruits to grow. Some great beginner cucumbers to grow at home are Socrates, Salad Bush, Unistars, and Bush Pickle cucumbers.

Finding the right cucumber variety for your home garden can make a big difference. As you shop for seeds, keep an eye out for words like ‘gynoecious,’ which means they only produce female flowers (cucumbers can have both male and female flowers), and ‘parthenocarpic,’ which refers to types of cucumbers that produce fruits without pollination.

Support

While you generally won’t need supports for most bush cucumbers, some cultivars may still benefit from being trained on a trellis. For plants that grow larger, this support will keep their long vines contained and growing upwards, allowing them more room to spread out. A stake or a hook secured to the ceiling can serve as an effective makeshift support.

Go from farm to table in a matter of weeks. Precision-engineered for easy growing and greater yields, Gardyn’s Home Kit 3.0 is the smarter way to grow cucumbers indoors.

How To Grow Cucumbers At Home

Starting cucumbers from seeds requires a bit of patience, but the process isn’t difficult.

Step 1: Preparation of Potting Mix

  • First, before planting, pre-moisten your potting mix. Nourish it with water and let it drain.
  • Step 2: Sowing the Seeds

  • Sprinkle your cucumber seeds evenly in your container, spacing them at least 7-8 inches apart.
  • Step 3: Covering the Seeds

  • Light cover your seeds with some potting mix about one-inch thick.
  • Step 4: Positioning the Pots

  • Keep your pots in a warm, sunny location.
  • Step 5: Watering

  • Keep the soil moist but never soggy.
  • Step 6: Germination

  • Cucumbers germinate in 1-2 weeks. If you don’t see any sprouts past that time, your setup might be too cold.
  • Gardyn offers everything you need to enjoy nature’s bounty at home. No dirt; no mess; no weeding; no hassle. Simply plug in your Gardyn Home Kit (no water line required), pop in the included yCubes, and watch your garden thrive. Shop for your model today.

    How To Care For Your Cucumber

    Cucumbers require about one inch of water per week to grow healthy and strong. Vining cucumbers or trellised plants, in particular, tend to absorb a lot of water. As a general rule of thumb: if the soil is dry on top, water the plant. Your cucumbers will taste bitter if left to wilt.

    When planting your cucumber plant, give it a good start with some fertilizer. Then, when you start to see leaves emerging, give it another dose. Cucumber plants grow fast, so you’ll also want to feed them consistently throughout the growing season. Fertilize regularly with a balanced fertilizer, and mulch around the base of your plants to provide added moisture and weed control. Do this around twice a month for the best results.

    Lastly, trim off any yellowing leaves and flowers. Sick leaves don’t benefit the plant, so remove them as soon as possible to promote healthy growth.

    What about transplanting?

    Cucumbers don’t really like being transplanted. In most cases, you can forgo this entirely. Direct sowing, or sowing the seeds directly in their final location, is the best way to grow cucumbers at home.

    If you do choose to transplant them, wait until the seedlings have grown to three inches tall (2-3 leaf stages). This is typically a month into germination. It’s also a good idea to wait until the weather outside is warm before moving your plants, or when the last frost has passed. Transplant carefully, handling the seedlings by their leaves rather than their stems. Plant in a garden bed, in soil that’s well-drained, moist, and rich in organic matter.

    Grow hassle-free with Gardyn. With Kelby Assist, you won’t miss a beat when it comes to plant care.

    Harvesting And Using Your Cucumber

    Cucumbers can take up to 2 months to reach full maturity, at which point they’re ready to harvest. Different cultivars reach different sizes when fully ripe, so make sure to read the ripeness guidelines for your variety before harvesting. Generally, however, most cucumbers are ready for picking when they reach 8 inches in length. Note that if you plan on pickling cucumbers, you’ll want to harvest them smaller — roughly 2 inches long.

    When to Harvest Your Cucumbers

    Once your plant starts producing, harvest every couple of days. If you leave them hanging too long, the cucumbers will overripe, turning color and becoming bitter. Even if you don’t plan to use the fruits, you should still harvest them as soon as they are ripe. This allows your plant to continue producing rather than putting its efforts into maturing overgrown cucumbers.

    Show your Cucumber Some Love

    When harvesting, it’s important to be gentle. Don’t tug or pull, as this can damage vines and impede future growth. The best way is to use a sharp knife or kitchen scissors to snip them off, leaving an inch of the stem still attached. This will help keep your cucumbers fresh for longer.

    Using Your Cucumbers

    Once harvested, cucumbers can be eaten fresh in salads or thinly sliced for wraps/sandwiches, pickled, stir-fried, or even frozen for smoothies or soups. If you end up with more cucumbers than you can eat, pickling, canning, and freezing are all great ways to preserve them. You can also safely store cucumbers for up to a week in the refrigerator.
