What is Haskap? What are the tips for cultivation?

Haskap, which bears elongated fruits that are blue like blueberries, is a famous fruit tree that is a specialty of Hokkaido. In fact, it is said to have high nutritional value, but since the skin is thin, it liquefies at room temperature, and it takes time to store it, so it is hard to see it. This time, we have summarized the scientific name, how to raise, and how to enjoy such Haskap

  • What is Haskap? What is the color of the flowers?

Scientific Name Lonicera

Family / genus name Honeysuckle family Honeysuckle genus

Place of origin East Asia

Flowering period April

Color of flower White

Haskap is a shrub fruit tree that is distributed from Siberia to China, the Korean Peninsula, and Japan. In Japan, it grows naturally only in the eastern half of the Yufutsu wilderness in Hokkaido. Although it is a plant that is resistant to the cold, it is very vulnerable to the heat. It blooms in pairs in spring and then bears fruit and bears long, blue fruits.

The name Haskap is derived from the Ainu word “Hashikabu,” which means “a lot on a branch.” Also, in Hokkaido, where it grows naturally, it is sometimes called by the common name “Yumi”. This is derived from the Ainu word “enumi tanne” which means “long-headed grain”.

Since the harvest time is short and the honeysuckle liquefies at room temperature, Haskap has been treated with great care as an elixir of immortality and longevity. In modern times, it is processed into jams and sweets and is popular as a special product of Hokkaido.

Haskap is a plant with low self-fertility and should be planted with other pollinated varieties such as blueberries. Therefore, plant two or more seedlings of different varieties close to each other. The optimum time for planting is from December to March.

When planting in the ground, choose a sunny and well-ventilated place and dig a deep hole with a diameter and depth of 50 cm or more. And since I prefer acidic soil, I mix peat moss and Kanuma soil with the garden soil. In addition, to improve the drainage of the soil, plow in the humus before planting.

For potted plants, prepare pots with a diameter and depth of 50 cm or more. The medium used is a mixture of Akadama soil (small grains) 7: peat moss 3 with unadjusted acidity.

The point is to plant both in the garden and in pots. Also, since it has a shallow rooting property, cover the roots with peat moss or straw to prevent it from drying out. Also, it is very sensitive to heat, so manage it in a cool environment in the summer.

  • How to water and fertilize Haskap?
  • Watering

Haskap hates drying. For potted plants, give plenty of water when the soil surface is dry. In the case of garden soil, it is not necessary to water it except on extremely dry days in the summer.

  • How to give fertilizer

As fertilizer, use organic fertilizer or fast-acting chemical fertilizer as the base fertilizer at the time of planting. Please refrain from chemical fertilizers. Then, add fertilizer in October for local planting and in February, June, and October for potted plants.

Please note that if the fertilizer contains a large amount of nitrogen, it will not produce a lot of fruit.

  • When and how to replant and prun the Haskap?
  • Replanting

Haskap potted plants are replanted in larger pots once every two years to prevent root clogging and keep the soil in a healthy condition. The best time to do this is from November to February, before the flowers come out.

  • Pruning
  • How to increase Haskap! When and how to cut the cuttings?

Haskap does not need to be heavily pruned. It is okay to thin out weak branches and crowded branches from December to February. On the other hand, if you switch back strongly, the fruit will not grow the next year, so be careful.

Haskap can be increased by stocking and cuttings. Shares should be split from November to February, and cuttings should be done from October to November or April to May. Cuttings are especially easy, just make cuttings about 20 cm long and insert about 2/3 into the soil. It is recommended to do it during pruning.

  • Which pests need attention when cultivating Haskap?

Pests such as scale insects, scale insects, and aphids may occur. Let’s remove pests as soon as they occur.

In addition, over-humidity can cause branch blight and Botrytis cinerea, so be careful not to give too much water and grow in a well-ventilated place. If the damage from the disease increases, spray a drug that can be used on deciduous fruit trees.

  • When and how to harvest the honeysuckle fruit?

Haskap can only be harvested for about a month from mid-May to early June. In addition, since the ripening time of the fruit varies, the fruit is picked and harvested in order from the dark blue one.

In fact, it is easily damaged and turns into a liquid at room temperature, so please eat it raw immediately after harvesting, or freeze and process it before use.

  • What is the taste and efficacy of Haskap?

The honeysuckle fruit has a slightly more sour taste than blueberries and raspberries. In recent years, some varieties have become sweeter due to breeding, but in fact they are easily damaged and are often processed into jam, fruit wine, and sweets instead of raw food.

In fact, it is richer in vitamin C, calcium, iron and anthocyanins than other fruits. In particular, anthocyanin, which is a type of polyphenol, has a strong antioxidant effect and can be expected to have effects such as suppressing blood pressure, preventing aging, and improving liver function.

  • How to make Haskap jam
  • Material
  • Haskap: 100g
  • Sugar: 50-150g (adjust to your liking)

3. When it becomes thick, turn off the heat. Add lemon juice

4. Cool until the heat is removed and transfer to a sterilized bottle.

  • Difficult to bear fruit by cultivating haskap

Haskap has a very low self-pollination rate and is considered to be a very difficult plant to bear fruit even if it is grown by itself. Therefore, if you try planting different varieties and trying artificial pollination, it may be easier to bear fruit.

It is a laborious and difficult plant to grow, but once you get the fruit, please enjoy it with jam or fruit wine.
