The majority of cucumbers produce both male and female flowers, also known as staminate and pistillate. Male flowers typically bloom several weeks before the female flowers, eventually dropping from the vine.
The center of male flowers contain a sticky tube covered in pollen. Whereas female flowers contain the center ovary. If pollinated, these will develop into cucumber fruits.
There are usually 10 male flowers to every one female flower. Depending on the varieties you are growing, most types are ready to be harvested around 50 days to 70 days. Overly ripe cucumbers produce a bitter taste and have a tough texture. To prevent damage to the vines, harvest by snipping them from the vine and not tearing them off. All varieties of cucumbers either grow by producing long vines or have a bushier habit of growth, producing short vines.
Which type that you choose to grow depends on how much space you have in your garden. To prevent disease problems, your plants will require room to spread with adequate air circulation. Depending on the cultivar, vining cucumbers are usually large, sprawling vegetables that require a large area to spread for proper growth. Some varieties can produce vines up to 10 feet long, although the growth of 5 to 6 feet long vines are typical.
After the cucumber plants begin to grow, thin them to one plant every 12 inches. Cucumber seeds and seedlings do not do well with cold temperatures. Planting seeds directly in the garden may not work in areas with short growing seasons. In this situation, you can start seeds indoors 2 to 3 weeks before the last frost. It will take 3 to 4 weeks for the seeds to grow to transplant size.
You should wait until after the last spring frost before putting seeds or transplants in your garden. If you have a tiny garden, you can grow your cucumbers and tomatoes, etc. For more information, check out my article on trellises. You can also check out this article from Michigan State University on how to grow cucumbers. This comes out to 1. Of course, your cucumber harvest will vary depending on the variety of plant you choose, as well as the quality of care you give your plants more on this later.
Some varieties claim to produce 65 to 70 cucumbers per plant in a season! For more information, check out the Bragger Hybrid Cucumber on the Burpee website. The fruit on a cucumber plant is normally dark green when ripe, with light green to white flesh inside. If the cucumber starts to turn yellow, then it has become over ripe.
In that case, the over ripe fruit should be harvested and discarded into your compost pile or to your chickens. Otherwise, the plant will continue putting energy into a fruit that is already too large and bitter to eat.
To avoid this, be sure to harvest your cucumbers every day or so, since the fruit grows quickly after the flowers are pollinated. Yes, cucumber plants will die after harvest. Cucumbers are an annual plant, meaning that they only survive for one year — long enough to produce fruit and spread seeds to reproduce. First, you can choose either pickling or slicing cucumbers. Pickling cucumbers are usually smaller, and used for preserving in glass jars by making pickles with vinegar, salt, dill, etc.
Slicing cucumbers are longer than pickling cucumbers. Slicing cucumbers are often used on sandwiches or salads. You also need to decide whether you want to plant bush or vine cucumbers. Vine cucumbers grow much taller than bush cucumbers, and are suitable for growing up a trellis. For more information, check out my article on how high cucumbers will climb. No, you do not need two cucumber plants to produce fruit. All stems are roughly hairy, have an angular cross section, may turn hollow when mature, and bear leaves singly at the nodes.
Stage I — Upright growth is the initial stage that starts when first true leaves emerge and it ends after nodes. Stage II — Vining - starts after 6 nodes.
Then, side shoots begin to emerge from leaf axils, while main leader continues to grow. Side shoots are also growing, causing the plant to flop over. Leaves are simple and develop at each node. Depending on variety and environmental conditions, flowers may begin developing at the first few nodes. Figure 1. Cucumbers are monoecious plants which have separate male and female flowers on the same plant Fig. The male flowers appear first and female flowers shortly later.
The female flowers have small immature fruit at the base of the flower and male flower do not have any. Pollen is transferred from male to female flower by bees or other insects. When pollinated properly, female flower develops into fruit. There are different types of cucumber hybrids such as gynoecious varieties that produce predominantly female flowers, and seeds of monoecious varieties are mixed with it for pollination. They are very productive when pollenizer is present.
Older cultivars, as well as many current cucumber cultivars, have a monoecious flowering habit, producing separate staminate and pistillate flowers on the same plant. Although the terminology is not botanically correct, staminate flowers are often referred to as male flowers and pistillate as female. Monoecious cultivars first produce clusters of five male flowers at the leaf nodes on the main stem. Subsequently, the plant produces both male and female flowers. Most current hybrids are gynoecious all female flowers.
Gynoecious hybrids are widely used because they are generally earlier and more productive. These modern F1 hybrids have several advantages. As they bear only female flowers the tiresome job of removing male flowers is unnecessary. They are also much more resistant to disease and rather more prolific.
There are two drawbacks — the fruits tend to be shorter than the ordinary varieties and a higher temperature is required. Production of female flowers is naturally promoted by the short days, low temperatures and low light conditions of fall. Flower femaleness can be promoted by applying plant growth substances PGRs such as NAA a type of auxin , and Ethephone an ethylene promoter. If a purely female variety is grown, need to provide an appropriate pollinator.
In sensitive gynoecious cultivars, production of male flowers is promoted by long days, high temperatures and high light intensity typical to the summer season. Production of male flowers also increases with high fruit load and with stresses exerted on the plant. There are also cucumber hybrids that produce fruits without pollination. These varieties are called parthenocarpic varieties, resulting in fruits that are called 'seedless', although the fruit often contain soft, white seed coats.
Such parthenocarpic fruit set also occurs naturally under the low-light, cool-night growing conditions, and short days of fall.
Older plants can also produce 'super' ovaries which set fruit parthenocarpically. Parthenocarpic varieties need to be isolated from standard varieties to prevent cross-pollination and development of fruits that do contain seeds, and may be deformed by greater growth in the pollinated area. On a normal cucumber plant, the first 10 - 20 flowers are male, and for every female flower, which will produce the fruit, 10 - 20 male flowers are produced. Flowering set progressively at the nodes.
Since each cucumber flower is open only one day, pollination is a critical aspect of cucumber production. One or more pollen grains are needed per seed, and insufficient seed development may result in fruit abortion, misshapen, curved or short nubbin fruit, or poor fruit set.
Hence, 10 - 20 bee visits are necessary per flower at the only day the flower is receptive, for proper fruit shape and size. Bringing in the bees earlier is unproductive because they may establish flight patterns to more abundant and attractive food sources such as legumes or wildflowers.
Bringing them in later jeopardizes pollination of the first female flowers. Build a Trellis. Avoid Bitter Cucumbers. Consider Your Climate.
Why are my cucumbers not maturing? You can identify a female flower by the tiny cucumber at the base. Male flowers lack these. If fruit is not developing even though female flowers are present, the cause may be lack of pollination.
Anything that interferes with pollination of the female flowers reduces fruit-set and yield. Why have my cucumbers stopped producing? Verticillium wilt, bacterial wilt and fusarium wilt are diseases that cause the vines to die, which slows or stops cucumber growth completely. Cucumber beetles damage the plants and spread disease. Controlling the beetles with wood ash allows for healthy cucumber plants that grow well. How do you take care of cucumber plants?
Thin cucumber plants in rows to 1 or 2 feet apart, depending on the variety, when 3 to 4 inches tail. Thin cucumber plants in hills to the healthiest two plants when plants have two or three leaves. Keep soil evenly moist to prevent bitterness in cucumbers. Apply a thick layer of mulch about 4 weeks after planting.
