Achocha: growing from seed, support, harvest and use in the kitchen

How to grow achocha (Cyclanthera pedata) from seed: April sowing, planting out after the last frosts, support, care, growing in a container, harvest and use of the fruits in the kitchen.

In short: Achocha (Cyclanthera pedata) is an annual climbing vegetable from the Andes, related to the cucumber. Start it in April at 20–25 °C, plant it out after 15 May by a support at least 2 m tall. Harvest the fruits from August until the frosts; eat young ones raw like a cucumber, larger ones cooked or stuffed.

Latin name	Cyclanthera pedata, gourd family (Cucurbitaceae)
Sowing on a windowsill	April, 1–1.5 cm deep, 20–25 °C, germinates in 7–14 days
Planting out	after 15 May, spacing 60–90 cm
Length of vines	3–5 m, a support is necessary
Fruit size	5–15 cm depending on the type, hollow inside with black seeds
Harvest	roughly 3 months after planting, here from August until the first frosts

Achocha is a plant that will raise questions from the neighbours in your garden. A few weeks after planting it covers a fence or pergola with fine, palmately divided leaves, and from summer dozens of pale green, slightly curved fruits hang on it. They taste like a cross between a cucumber and a green pepper, and because they are hollow inside, they suit stuffing.

In the Czech Republic it is sometimes called the Andean or pepper cucumber. It is grown similarly to cucumbers and squashes, but it comes from high altitudes in the Andes and usually tolerates cooler nights somewhat better. It does not tolerate frost, however. Below you will find the procedure from seed to harvest, advice for a balcony and how to process the fruits.

What achocha is and where it comes from

Achocha belongs to the gourd family, like the cucumber, courgette and squash. It comes from South America, where Indigenous people in the Andes grew it before the arrival of Europeans; it is also depicted on old Peruvian ceramic vessels. Today it is grown from Mexico to Bolivia and in recent years also in European gardens.

It is an annual vine with tendrils. The stems grow 3–5 metres long and need a support. Male and female flowers are on the same plant, so even a single plant bears fruit. The fruits are egg-shaped, curved and pointed, with soft spines on the surface. Inside is a cavity with several flat black seeds.

Characteristic	Achocha	Cucumber
Growth	vine 3–5 m, smaller leaves	vine or bush 1–3 m
Fruit	5–15 cm, hollow, a few seeds	solid, many seeds
Flavour	cucumber with green pepper	typical cucumber
Cold	tolerates cooler nights, not frost	sensitive to cold
Use	raw, stewed, stuffed, pickled	raw, pickled

Sowing and starting under cover step by step

Achocha needs a longer season than direct sowing after the last frosts offers. Starting under cover gives you a lead of 3–4 weeks and the first fruits already in August.

Timing: sow on a windowsill in the first half of April. An earlier sowing makes no sense, as the seedlings would overgrow.
Containers: sow 1–2 seeds each straight into peat pots or seed pellets. Gourds tolerate root disturbance badly when transplanted.
Depth: lay the seed flat 1–1.5 cm deep in moist seed compost.
Warmth: keep at 20–25 °C. They usually germinate in 7–14 days, in the cold more slowly and unevenly.
Light: after emergence put the seedlings on the brightest window. Of two seedlings that come up, keep the stronger one and snip off the other.
Hardening off: from the beginning of May take them outside during the day, first into shade.
Planting out: after 15 May, once there is no frost, plant them out together with the peat pot in a sunny, sheltered spot.

Direct sowing in the bed is possible from mid-May, but the harvest then starts later and in a cool year is smaller. You will find general advice on starting gourd vegetables in the article cucumbers – salad, pickling and snake types.

Position, support and care during summer

Where to plant achocha

Best in a sunny or lightly partly shaded spot sheltered from wind, by a fence, pergola or a wall with a trellis. The soil should be humus-rich, nutritious and well-drained. Work compost into it before planting. Choose a spacing of 60–90 cm between plants; a single plant covers several square metres of support.

Support

Without a support achocha sprawls over the ground and the fruits rot. Netting with a 10–18 cm mesh, wire mesh or strings stretched up to the top of a pergola are enough. The support should be at least 2 m tall. The tendrils grab on by themselves; at the start just direct the young shoots.

Watering and feeding

Watering: regularly, at the roots, not on the leaves. The soil should not dry out completely; in summer heat water generously 2–3 times a week.
Mulch: a layer of cut grass or straw around the roots holds moisture and suppresses weeds.
Feeding: from the setting of the first flowers every 2–3 weeks with a fertiliser for fruiting vegetables. Too much nitrogen makes lush leaves and few fruits.

Achocha is usually healthier than cucumbers. In a damp, cool end of summer powdery mildew may appear; airy training of the shoots and watering at the roots help. How to mulch properly is described in the article why mulch a bed.

Achocha on a balcony and in a container

Achocha is one of the few climbing vegetables that work well as a green screen on a balcony. It needs a large container and a firm support, though.

Allow a container of at least 20–30 litres per plant, with holes in the bottom.
Use good-quality vegetable compost with a little compost mixed in.
Fix the support to the railing or ceiling, as a plant laden with fruits is heavy.
In a container water daily in summer, in heat even twice. Feed regularly; in a small volume of compost the nutrients run out quickly.
It does best on an east- or west-facing balcony; on a south-facing one shade it at midday, or the leaves wilt in the heat.

Harvest and use in the kitchen

The first fruits come roughly three months after planting, usually in August here. After that the plant fruits continuously until the first frosts. Harvest often: the more fruits you pick, the more new ones it sets.

Fruit size	How to use it
young, up to half of final length	raw in a salad or like a cucumber, whole with the seeds
fully grown, still pale green	halve lengthways, remove the seeds, stew, sauté, bake
large, firm	stuff with a meat or vegetable filling, roast in the oven
overripe, hard, turning yellow	for seed for next year

The fruits can also be pickled in a sweet-sour brine like cucumbers. Young shoots and leaves are also edible and are cooked as a vegetable in South America. From ripe fruits you can collect the black seeds, dry them and sow again next year; achocha does not cross with other gourds.

The most common mistakes when growing achocha

Sowing too early: seedlings from March overgrow and stagnate for a long time after planting out.
Disturbing the roots: transplanting from a seed tray slows growth by weeks. Sow straight into individual pots.
No support: fruits on the ground rot and slugs nibble them.
Planting out before the last frosts: even a light frost destroys the plant.
Late harvest: overgrown fruits are tough and the plant stops setting new ones.

Frequently asked questions

What does achocha taste like?

Young fruits taste like a crisp cucumber with a note of green pepper. Cooked, they are milder and soak up the flavour of spices and filling.

When should I sow achocha?

On a windowsill in the first half of April, straight outdoors only from mid-May. Plant out in the bed or container after 15 May.

Does achocha need a support?

Yes. The stems grow 3–5 metres long, and without a support the fruits lie on the ground and rot. Netting, mesh or strings at least 2 metres tall are enough.

Can achocha be eaten raw?

Young fruits yes, whole with the seeds, like a cucumber. Larger fruits are eaten more cooked or stuffed; remove the seeds from them.

Can achocha be grown on a balcony?

Yes, in a container of at least 20–30 litres with a firm support. On a balcony it forms a dense green screen; it just needs regular watering and feeding.
