Heirloom cucumber with slender, ribbed 50 cm fruits, 25 heirloom seeds

Chinese Long cucumber seeds, an heirloom and vigorous variety, produce slender, ribbed fruits of about 50 cm, which can reach 1 m when hung from a trellis. The packet contains 25 organic, open-pollinated seeds. Sow under cover from March to May, at 18 to 20 °C, for a harvest from July to October.

Long de Chine is an old, vigorous cucumber variety that produces an abundance of slender, ribbed fruits of about 50 cm. Hung from a trellis, they can reach 1 m. The flesh is firm, crunchy and mild, with few seeds, so you can slice them without deseeding.

🧗 Train it up or let it trail

How you train it depends on your climate. In a dry region, the stems can trail along the ground, where mulch keeps moisture at the base. In a wetter region, train them up a trellis or netting: the foliage dries faster after rain, and the fruits no longer rest on wet soil. A hanging fruit also forms straighter and longer, hence lengths close to 1 m on trained plants. To tie the stems back over the course of the season, a tape tying tool fixes each tie with a single squeeze of the hand.

An 80-litre tank beneath the grid

For a cucumber in an aquaponic system, choose the aquaponic grow bed in its 80 L size, the one for fruiting plants whose roots search for depth. Fill it with rinsed clay pebbles, then fix the trellis to a structure independent of the bed, which will carry the weight of the stems laden with fruit. Allow one plant per bed, which respects the 1 m spacing this variety requires.

☀️ From seedling to harvest

Cucumber loves warmth and rich soil. Sow in pots at 18 to 20 °C, from March to May under cover, then transplant the whole root ball after the last frosts. Direct sowing in place remains possible in May and June, once the soil has warmed up well and nights are above 15 °C. Mulch after planting, which retains water and protects the plant from the cold. Watering must stay regular throughout the growing period, because sudden swings make the fruit more bitter. You will find more seasonal pointers in the guide to succeeding with spring sowings.

Sow

Sow in small pots from March to May, at 18 to 20 °C, 6 weeks before planting out.

Planting

After the frosts, transplant the root ball into a hole enriched with compost, 1 m apart in every direction.

Harvest

From July to October, cut the fruits while they are still firm, every 2 or 3 days.

In a tub as in the vegetable garden, you pick every 2 or 3 days in peak season, with secateurs, leaving a short piece of stalk. A forgotten fruit grows larger, hardens and turns yellow, and the plant then slows its production for the rest of the season. On a water-based system, this regularity matters all the more because growth is fast in summer, when the water is warm, and a fruit quickly gains several centimetres between one visit and the next.

💧 On a water-based system

In aquaponics, the cucumber is managed like other fruiting plants: it needs a system that has already cycled, rich enough in nutrients to carry fruit, and a deep growing bed filled with clay pebbles, because deep water culture holds a plant of this vigour poorly. Vertical training is even more worthwhile here than in open ground, since a trellis fixed above the bed gives you back the surface the stems would have taken up by trailing. The guide to the nitrogen cycle helps you know when your tank is ready.

What you need to know

Install the trellis at the same time as the plant. A structure added 3 weeks later means handling a stem that is already long, and the tendrils snap at the slightest strain.
A hanging fruit grows straight and can reach 1 m, whereas a fruit resting on the ground curves and gets marked. Training therefore changes the shape of the harvest.
Bitterness comes mostly from irregular watering. Water regularly rather than in fits and starts, and mulch around the base in open ground.
Never let a fruit turn yellow on the plant. The plant then puts its resources into ripening its seeds and slows down its production for the rest of the season.
Mulch after planting: mulch retains water and protects the plant from the cold early in the season.
In aquaponics, growing vertically has an extra benefit: a grow bed is expensive per square metre, and a trellis gives back the surface the plant would have taken up by sprawling.
