Can you over apply nitrogen to cucumbers?
High levels of nitrogen in the soil will cause excessive growth and delayed flowering and fruit set; therefore, do not over apply nitrogen. Cucumbers will respond to nitrogen fertilizer, so top-dressing (applying fertilizer to the soil surface then cultivating or watering it into the soil) is advised.
What is the best fertilizer for cucumbers?
Cucumbers require fertilizer that is low in nitrogen and high in potassium and phosphorus. Cucumbers have low nitrogen requirements, but they need high potassium and high phosphorus levels. With commercial fertilizer formulas, this means the first of the three numbers on the package should be lower, for instance, 5-10-10.
What nutrients do cucumbers need?
Nutrient Requirements. Cucumbers have low nitrogen requirements, but they need high potassium and high phosphorus levels. With commercial fertilizer formulas, this means the first of the three numbers on the package should be much lower than the other two. Knowing your soil type helps determine how much and what nutrients your cucumbers need.
What are the symptoms of nitrogen deficiency in cucumbers?

Feed your cucumber plants with a high nitrogen feed every two weeks. Cucumber plants like sun, but are prone to scorching, so some shade is preferable. Encourage greenhouse varieties to climb to boost yields. Harvest fruits early in the day while it's cool.
What happens if you give too much nitrogen to a plant?
Plants given slightly too much nitrogen show excessive growth and a softer plant; leaves will be darker green and sometimes thickened and brittle.
Why do plants need nitrogen?
Most plants need nitrogen in large amounts. It is generally considered to drive plant growth. Nitrogen plays an essential role in the composition in all proteins in all plants. Since it is a major structural and functional factor for every plant, crop yields are highly dependent on N availability to the plant.
How to prevent copper deficiency in peat media?
To prevent copper deficiency in peat media, where it is most common, add copper sulfate at 10 g/m³, as a precaution. Generally, nutrient solutions should contain 0.03 ppm Cu. For quick results, spray plants with a solution of copper sulfate using up to 1 g/L, plus calcium hydroxide (approx. 0.5%) for pH adjustment.
Why is zinc toxic to plants?
Zinc toxicity can be caused by contamination of the water used in soilless culture. Contact of corrosive nutrient solutions with galvanized pipes or fittings has been known to lead to zinc toxicity in sensitive seedlings. Galvanized greenhouse frames and wires are other possible sources of excess zinc.
Why is copper deficiency unusual?
Copper deficiency is unusual, partly because the widespread use of copper in plumbing and in fungicides ensures an adequate supply in most cases. Occasionally it becomes a problem with crops in peat media or in all plastic hydroponic systems when no copper is added to the nutrient solution. High soil pH reduces available copper, but this effect is much smaller than for manganese, iron, and boron.
How to get rid of excess fertilizer in garden?
Leach the soil or growing medium with fresh water to remove the excess fertilizer.
Where is potassium found in plants?
On a whole organ basis, potassium is generally equally distributed between roots and shoots.
How to fertilize cucumbers with liquid fertilizer?
The best way to use liquid fertilizer on a cucumber plant is by giving them a small dose every day. Consistency is the key to success. From my experience, if you add more than the required amount of fertilizer, the plant will only produce an excessive amount of foliage.
How to slow down cucumber plant growth?
Similarly, adding a low amount of fertilizer will slow down the growth of the cucumber plant. It is best if you feed the plant with a small dose of liquid fertilizer every day. Add the liquid fertilizer to the base of the plant so that the soil absorbs it. If you are using a granular fertilizer, sprinkle that in the roots too. Make sure you do not sprinkle the granular fertilizer directly on the plant, as that may burn and damage the crop.
Why Use A Fertilizer?
Not adding fertilizer to the plant will slow down the growth of your cucumber plant, and the crop will underperform. Using a fertilizer will also make sure you end up with a crop that yields more cucumbers on a single vine. In addition to that, fertilizers will deliver bigger and juicier cucumbers.
Why add coffee grounds to cucumbers?
Adding 5% coffee grounds to the compost mixture will keep the crop safe and protected from mildew diseases.
Do cucumbers need fertilizer?
In addition to water, cucumber plants need fertilizers to grow rapidly and thrive. However, before you start throwing fertilizer on your cucumber plant, it is important to know which fertilizer your plant needs. Understanding the needs of your cucumber plants and the type of fertilizer it requires is important if you want your cucumber plant to thrive. If your crop is in the beginning stages, it will be best to use granular fertilizer with low nitrogen but high potassium and phosphorus.
Can you grow cucumbers with fertilizer?
Growing a cucumber plant is an easy task that does not require any special gardening skills. However, keeping the plant alive by feeding it the right type and amount of fertilizer is not as easy. Being a novice, knowing which fertilizer is more suitable for your cucumber plant can get tricky.
Do you fertilize cucumbers?
Yes, you should always fertilize your cucumbers when you plant them. However, cucumber plants also need to be fertilized when you add mulch and when the plant starts growing. Adding fertilizer in the growth stage will boost the growth and deliver ripe fruits.
How often should cucumbers be harvested?
Cucumber producers should to take into consideration the high amount of labor required for harvest. For slicing production, harvesting will need to be repeated several days each week to maintain additional fruit set. Processing cucumbers may allow for a one-time harvest, which will reduce the long term need for harvest labor.
What type of soil do cucumbers grow in?
Cucumbers grow best on well drained, warm, sandy or silt loam soil , but a variety of soil types can be used. Where early harvest is of importance, sandy soils located where there is good sun exposure and air drainage are best. If soil drainage is less than optimal, cucumber will benefit from the formation of free-standing raised soil beds, which also will capture more heat from direct sunlight, speeding emergence and development of the crop. These beds can be formed by using a commercial bed-shaper. Drip irrigation tape and plastic mulch also can be installed with most bed-shapers during bedding.
How to prevent cucumber disease?
Many of the fungal, bacterial, and nematode pathogens survive in old crop debris and in soil. Fields should be rotated with non-cucurbit crops for at least three years to reduce pathogen levels. Grass crops are ideal for rotations where nematodes are a problem. Select well-drained soils to minimize damping-off, root rots and fruit rots and consider using free standing raised beds to improve soil drainage . Late plantings should not be situated nearby and downwind of early planted cucurbit fields where foliar or virus diseases already exist. Avoid the movement of contaminated soil or plant debris into clean fields on workers or equipment. Diseases such as anthracnose, angular leaf spot and gummy stem blight are known to be carried on seed. This can lead to the introduction of diseases into clean fields. Purchase seed from reputable sources and apply a fungicide seed treatment prior to planting. Most foliar diseases are spread by water-splash or are favored by long periods of leaf wetness. Utilize drip irrigation or avoid frequent sprinkler irrigations with small amounts of water. Finally, till fields soon after harvest to promote the rapid decomposition of old vines and fruit.
How long does it take for cucumbers to grow?
Transplants also can be used for establishment of cucumber and will take approximately three weeks to four weeks to produce prior to transplanting in the field (HLA-6020). That said, unless the producer is targeting a very early market, transplants aren’t normally used as the medium-sized seeds will germinate and grow rapidly when soil temperatures are conducive to germination. Transplanting into raised beds covered with black plastic mulch will reduce the time to harvest, particularly during cool, wet springs.
How to increase organic matter in a clean tillage system?
One solution to this loss of organic matter would be the use of winter cover crops to increase soil organic matter. When a winter legume such as Austrian winter pea or winter clovers, etc. are included with a cereal grass in the cover crop mix, not only will soil organic matter be increased, but also there will be a gain in available nitrogen for subsequent warm-season crops such as cucumber.Research has indicated a direct benefit to using cover crops with at least one legume in the cover crop mix in the winter prior to planting a warm-season crop such as melon. In an organic system, legume cover crops are a good source of nitrogen that will be available for an extended period during the growing season.
Where does cucumber come from?
Cucumber is native to India and is one of the oldest vegetables mentioned throughout history. Cucumber includes three different types of cultivars including fresh market (slicers), processing (pickling) and greenhouse (slicers). Regarding cucumbers nutritional value, very little vitamin A is available from the fruit, particularly if it is eaten peeled, although some vitamin C is contained in the fruits (Peirce, 1987). Cucumber is monoecious (female and male flowers separate on the same plant), but several varieties developed within the past 40 to 50 years are gynoecious meaning they produce mostly female flowers and require some monoecious pollinator plants to be in the field to provide for pollination (Iowa State University, 2020). Parthenocarpic varieties often are used in greenhouse and high tunnel production, since they do not require pollination to develop fruit (Guan, 2018).
How far apart should cucumbers be planted?
Seed should be spaced 9 inches to 12 inches apart in the row, with a thinned spacing of 12 inches between plants.
What temperature should cucumbers be?
The ideal temperature for optimal growth and yield is 65 to 75 degrees, with minimum growth temperature of 60 degrees and a maximum growth temperature of 90 degrees.
How long does it take for cucumbers to grow?
Cucumbers (Cucumis sativus) grow quickly, with most varieties going from seed to table in 48 to 58 days. They grow in United States Department of Agriculture hardiness zones 4 through 12 and need full to partial sun, meaning at least six unobstructed hours of sunlight per day.
Do cucumbers need pollination?
Pollination. Varieties of cucumbers with both male and female flowers need pollination, while those with all female flowers – seedless varieties – don’t. The first flowers to appear are male, then the female flowers come out. The female flowers have what looks like a tiny swollen pickle in the center.
What plants need nitrogen?
Responsive to extra nitrogen are: tomatoes, peppers, greens, sweet corn, pole beans, muskmelons, cucumbers, squash and okra. Tomatoes should receive 1 tablespoon of ammonium nitrate or urea per plant after first fruits are 1 inch in diameter and again at three-week intervals during fruiting.
How to run a germination test?
To run the germination test, place seeds between layers of wet blotters and see how many sprout.
How much overfill is enough to damage a tree?
But too often these trees are damaged or killed by overfilling when the final grade is put on the lawn. Just six inches of overfill is enough to damage many trees.
Where to store seeds?
Two good places to store seeds are in the attic or an unheated room upstairs. Be sure to protect them from rat and mice damage, too. Then, next spring run a germination test just before you plant the stored seeds.
Can you buy more vegetable seeds than you can use?
It's a good practice not to buy more vegetable seeds than you can use during a single growing season. But, if you have leftover seed that you'd like to store for next year's planting, follow these storage tips.

- Several varieties of cucumber are grown in Oklahoma, see OSU Extension HLA-6035 “Commercial Vegetable Varieties for Oklahoma”for more information. Listed below are varieties that have performed well in Oklahoma. On-farm trials are important in reducing the risk of trying new varieties. Disease resistance varies considerably between varieties. Disease resistance should b…
Soil Ph and Fertilizer
- Base soil pH and fertility needs for the crop on soil test results and recommendations. Cucumbers are tolerant to a wide range of soil pH, but soil with a pH between 6.0 and 6.8 is preferred. If the soil pH is below 5.8, it should be limed to increase the pH to 6.0 or above. Base liming rates and recommended amounts of phosphorus (P2O5) and potassi...
Planting and Plant Spacing
- A key aspect of establishing cucumbers is waiting until the soil temperature at planting depth is at least 60 F (75 F to 90 F optimal germination temperature), otherwise plants will be slow to emerge and crop stands will be variable with plants in various stages of growth. In addition, cold soil temperatures early in the season can result in blossom end rot (BER). Blossom end rot is a physi…
Weed and Moisture Management
- Whether conventional clean tillage, strip tillage or mulches are to be used, producers will encounter weed competition when producing cucumbers. Weed control will be critical in the early growth stages while seedlings or transplants are small. Shallow cultivation by tractor-drawn cultivators, hoeing by hand or hand tilling will be required in the early stages of crop developmen…
Irrigation
- Adequate moisture is needed by all crops to grow and flourish. Cucumbers require moderate amounts of moisture while making their most vigorous growth early in the season and until the early fruit-set is fully sized. Irrigation is needed when the crop is not receiving adequate rainfall to meet its needs. If adequate rainfall is lacking, it will be necessary to provide supplemental irrigat…
Field Scouting For Crop and Pest Development
- Fields should be scouted at minimum once per week after planting by walking across the entire field in a V-shape or X-shape pattern and recording plant development and weed and insect occurrence and numbers. Results of surveys will be needed to make decisions regarding projection of harvest date, the need to bring in honey bees for pollination and pest control decisi…
Insects
- Fields previously in sod or having heavy infestations of weeds in the prior year should be treated with a soil-applied insecticide at planting to control soil insect pests including cutworms. Small seedlings are extremely susceptible to feeding damage from adult striped and spotted cucumber beetles. Protecting seedlings may require treatment with a foliar-applied insecticide to prevent c…
