What kind of vegetables are cucumbers?
Cucumber is indispensable as a representative of summer vegetables.
It was during the Edo period that cucumbers were cultivated as vegetables in Japan.
In the old days, it was common for people to have strong bitterness and warts, powder on the skin, and bending.
However, breeding has progressed, and now there are many straight cucumbers that have no bitterness or green odor, and have no warts or powder.
If you want to grow it in a detached kitchen garden or on the balcony of an apartment, we recommend a small cucumber that has a compact plant height and can be harvested in large quantities.
On the other hand, if you grow it in the field, the old-fashioned wart cucumber that grows big and long is good.
Why don’t you try growing cucumbers at home?
Cucumber cultivation schedule
Cucumber cultivation schedule,
– planting season: mid-March to May
-planting season: mid-April to May to early
-flowering period: late April to August in mid
-harvest: June to mid-August
and It has become.
It takes about one and a half months for seedlings from planting to harvesting.
It takes about one week from flowering to harvest.
The period from sowing to harvesting is about one and a half months, and the growth speed is fast, so it is important not to run out of fertilizer and water.
Autumn sowing is directly sown.
It is sown in early August and harvested from mid-September to mid-October.

How to grow cucumbers
Let’s introduce how to grow cucumbers, which is recommended for beginners in gardening.
Soil is very important for growing cucumbers.
If it is planted in the ground, the roots are wide and shallow, so it is vulnerable to over-humidity and dryness, and will not grow in soil with poor drainage and air permeability.
Plow to a depth of about 15 cm to make it easier for the roots to grow, and raise the ridges to improve drainage.
pH 6.0-6.5 is good.
If you want to grow it on a balcony or other planter, we recommend using commercially available potting compost for vegetables.
When mixing by yourself, adjust the acidity with a ratio of 7 Akadama soil, 2 humus soil, and 1 vermiculite.
Soil is indispensable for gardening, as it can be said that “good soil selection is the key to successful gardening.” Therefore, if you make a mistake in selecting the soil, the plant may die quickly, it may not grow easily, or it may fail. Therefore, this time, we will introduce the recommended soil and how to choose it for those who are new to gardening or who have tried several times but have failed.
For pot sowing (9 cm), dig a hole with a diameter of 3 cm and a depth of 1 cm, and separate a few grains.
For boxing, sow seeds at intervals of 1.5 to 2 cm at a width of 2 cm and a depth of 1 cm.
Cover the soil with about 5 mm and then water it thoroughly.
Be careful not to plant too deeply.
If all goes well, it will germinate in 4 to 5 days.
When the cotyledons come out, two pots are erected, and when one true leaf is reached, one is thinned out.
At this time, if you pull it out, it will damage the roots of the remaining stock, so it is important to cut it off at the ground.
Boxing is transplanted to the pot after the cotyledons have opened.
The seedling raising period until planting is about 30 days, and the seedlings are made into 3 or 4 true leaves.
If the leaves touch, increase the spacing between the pots.
After germination, improve ventilation and lower the temperature.
In the case of crawl varieties, it is directly planted in the open field after the temperature rises.
In the case of a planter, select a large pot with a soil capacity of 20 L or more and plant one plant.
It is recommended to put it in a sunny place such as a balcony.
Also, if there is a lot of water at night, it can cause a legginess, so it is recommended to water as much as possible in the morning.
How to set up a support
The stanchions are upright when cultivated in one row and the number of plants is small.
Ideally, the length of the stanchion should be 210-240 cm.
If there are two rows, the columns will be erected in a gassho style.
Until your parents are firmly entwined with the net, tie them to the net diligently with twine.
When the parent extends to the height of the column, pinch it.
Set up columns and nets next to the planted cucumbers.
Since it is unstable with only one support, use at least two to increase the strength.
This completes a sturdy support that will not break or fall.
By expanding the net, it becomes cool like a green curtain.
Be careful not to sag.
The green curtain looks cool and looks good.
If it’s a balcony, it’s a good idea to have a set of stanchions and a net.
It is easy to install, so it is recommended for beginners.
Cucumbers that are sensitive to drying.
Water every day in the summer, avoid the daytime under the scorching sun, and water well after the temperature drops, such as in the morning or evening.
Since the roots are shallow, the point is to make the soil well and improve the roots.
In the summer, cucumbers consume a lot of water.
There should be no shortage of water.
It is important to keep the soil from drying out.
Be very careful when watering so that you don’t run out of water.
Disease and pest control
・ Powdery mildew:
Thin, white powdery mold develops on the leaf surface.
The leaves and stems become malformed, and if they are severe, they turn yellow and die.
It is a disease that is easy to detect from the early stages.
As a feature, it is said that it tends to occur when the humidity is low and it is dry.
As a countermeasure, cut off the affected leaves and dispose of them as soon as possible.
・ Viral disease:
Mosaic symptoms of green shades appear on the leaves, causing deterioration of growth and fruit set.
Aphids carry the causative virus.
Yellowing, atrophy, and appearance of mottled patterns can be seen on the leaves and stems.
It tends to occur from September to November when there is little rain, and there is a transmission route by aphids.
There is no countermeasure, and thorough control of aphids is the only preventive method.
A group of small insects with a body length of 1 to 4 mm sucks and damages.
Aphids are representative of pests that have amazing fertility and mass attacks.
The solution is to crush it as soon as you find it.
Thrips palmi Karny:
Thrips are also vectors of viral diseases.
Small adults and larvae with a body length of 1 to 2 mm parasitize the gaps between the shoots and leaves.
Care must be taken as the sucking part is necrotic.
It tends to occur during the high humidity period from July to September, and it is difficult to remove it, so it is recommended to pick it frequently after the symptoms appear on the shoots and leaves.
