You can recognize the male flowers because they do not have a small fruit behind them. They produce the pollen needed to form the fruit, but they do not produce the fruit. The male flowers begin forming before the female flowers form. So, it is possible to have cucumbers blooming, but not producing fruit.

If there is a seed inside, you have a pollinated plant. Another indication of pollination can be the colour of her pistil hairs. When a female has been pollinated, the previously white hairs will soon shrivel and become darker.

They take pollen from one plant to another, thereby making plant reproduction possible. Pollination isn’t necessary to make flowers grow and bloom, but it is necessary for many plants to grow fruit. If many plants aren’t properly pollinated, they cannot bear fruit or produce new seeds with which to grow new plants.

Inspect the bright yellow flowers growing on the cucumber plant. Look behind each flower for a small immature cucumber growing behind it. Female flowers have this immature bloom, known as an ovary, growing behind it, while male flowers do not. Male flowers grow on a thinner-looking stem.

A: Pinch off the flowers if you want more stem and leaf growth – especially if the plant is young. You can remove flowers on the bottom so the plant will focus more on the top cucumbers (this will keep cucumbers off the ground too).

Cucumber pollen is produced in a sticky mass and is not windblown. Hence, pollination requires the activity of insects that move pollen from male to female flowers, with bees being the most common pollinators. Gynoecious cucumber plants, however, produce only female flowers.

This well-pollinated cucumber plant is growing a new cucumber. The fruit comes from the female flower, pollinated by pollen transferred from a male flower, like the bright yellow one above. Ideally, pollen is transferred by bees, but if not, hand-pollination is an option.

The ovary of the female flower looks like a baby fruit and is located behind the flower’s petals. When the female flower is pollinated, the fruit begins to develop. High-yield “gynoecious” cucumber hybrids designed to produce smaller, pickling cucumbers have a higher percentage of female flowers.

The female flowers have longer stems. You can see one female flower at one place. They’re not clusters as the male flower, rather they’re always decluster. The female flower has small fruit at the base of the stem even before pollination takes place.

Fertilization Process In cucumbers, the fruit develops around the seed, and each fruit produces more seeds in its center. Cucumbers appear at the center of each fertilized female flower as tiny green finger-like projections that enlarge almost daily as production progresses.

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. Or the numbers overall should be low, such as 4-4-4, rather than 20-20-20.

Spinach, cucumbers, beans and tomatoes are some of the vegetables that seem to benefit from the anti-microbial activity of coffee grounds. They are prone to many rust and mildew diseases, especially when they are in the seedling stage. Compost containing just 5% coffee grounds can provide this protective effect.

The calcium in the eggshells will make your cucumbers naturally crisper–both raw and after they’re pickled! And finally, if you’re NOT out of eggshells yet, crush them up very finely and use them to make a ring around slug-prone plants like lettuce, potatoes and hostas.

Your cucumbers might be a bit weathered and worn come mid season. You can use Epsom Salts as a way to green them up and give them a boost. This is true for both container and ground planted cucumbers. If you are growing cucumbers in containers, you should be feeding them at least 2x’s a month when they are producing.

Most plants can be misted with a solution of 2 tablespoons (30 mL) of Epsom salt per gallon of water once a month. For more frequent watering, every other week, cut this back to 1 tablespoon (15 mL).

2. To Prevent Slow Growth In Cucumbers. Gardeners use Epsom salts because they are made up of a compound called magnesium sulfate. When plants don’t receive enough of these essential elements (magnesium and sulfur), it affects their growth, their strength, and their yield.

Tea leaves are a good addition to the compost heap. However, tea bags are not. This will not break down in the domestic compost heap, and indeed particles will remain even after commercial ‘green waste’ composting. Some brands use instead a polymer fibre derived from plant starch, called PLA.

In fact, banana peels have the highest organic sources of potassium. Potassium aids plants in moving nutrients and water between cells. Potassium strengthens plants’ stems and also fights off disease.
