How to Grow Achochas UK | Regional Planting Calendar
Move through the SoilCommander growing library like a course: keep the navigation in place, open the next lesson, and build your garden plan step by step.
Timing is the decision that matters most in the UK: there are 4 separate regional sowing windows, ranging from early April in Southern England to early April in Scotland.
Core growing advice on this page is checked against named horticultural and university-extension sources — see References.
Garden Organic: sow April-May under cover at 20-25C; a single window is applied uniformly across all four sub-regions since the source gives no UK-region-specific gradient for this half-hardy tender climber.

Sow April-May, two seeds per 9cm pot or singly in large modules, covered lightly, kept at 20-25C; germinates in around 10 days (Garden Organic).
Planting out and establishment
1
Plant out May-June around the four-leaf stage once conditions are warm enough outside, spaced at least 35cm apart, with netting or stake support in place (Garden Organic).
Climbing growth and flowering
6
Vigorous tendril-climbing vine scrambles up walls, fences or netting; greenish-white flowers appear; pinching the tops back once plants reach the top of their support is said to encourage fruiting (RHS, Garden Organic).
Fruiting and harvest
8
Harvest as soon as fruit reaches edible size, from late July until frosts; fruits become hollow and do not change colour as they ripen (Garden Organic).
When to pick: Harvest fruit young and tender for eating raw (cucumber-like flavour); older fruit becomes fibrous and needs cooking. Prolific fruiter -- continued harvesting encourages more fruit through to autumn frosts.
Garden Organic: harvest as soon as fruit reaches edible size, from late July until frosts; fruits become hollow and do not change colour as they ripen.

Frequently Asked Questions
When should I sow achochas in the UK?
In Southern England, from early April. In Scotland, wait until early April. Treat these as a guide rather than a fixed date — the governing rule is to sow only once frost risk has passed and temperatures are reliably warm enough.
When do I sow achochas?
Sow early April to late May.
How long do achochas take to grow?
Typically 75–105 days, depending on cultivar and growing conditions.
What problems affect achochas?
Our data links 1 disease and 1 pest to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
Most of the advice on this page comes down to timing and spacing — sowing at the right moment, rotating beds, and giving plants enough airflow. The UK Garden Planner lays your plot out month by month so those decisions are already made before the season starts.
