Plan on at least 5 gallons (about 19 litres) of soil for a bush cucumber and 10 gallons or more for a vining cucumber grown up a trellis. Grow one bush cucumber per pot, and keep the pot evenly watered.
Does your pot fit?
Cucumber pot size by type
| Cucumber type | Pot size | Litres |
|---|---|---|
| Bush or compact | 5 gallons minimum | 19 |
| Vining, on a trellis | 10 gallons or more | 38 or more |
Guidance varies a little between sources, and some suggest more for vining types in hot weather. Treat these as minimums. A pot at least 12 inches deep also helps.
Choose a bush variety to start
Bush cucumbers stay compact and need little or no trellising, which makes them the easiest choice for a balcony or patio. Look for “bush”, “compact” or “patio” in the name.
- Spacemaster: a bush variety that works well in tight spaces.
- Bush Champion: a dwarf hybrid that needs less space.
- Salad Bush: compact vines that need only minimal support but give full-size fruit.
- Patio Snacker: thrives in pots and does well with a trellis or stake.
If you have room for a bigger pot and a trellis, vining types such as Lemon, Picolino and National Pickling can crop heavily and for longer.
Pot checklist
- Drainage holes are essential.
- Put the trellis in when you plant, and make it sturdy enough to carry the weight of the fruit.
- Cucumbers need steady moisture. Container plants dry out faster than garden plants, so check the pot every day in warm weather.
- Frequent watering washes nutrients out of potting mix, so feed regularly.
- Pick often, about every other day, to keep new fruit coming.
Common questions
Can I grow a cucumber in a 5 gallon bucket? Yes, a bush type. Five gallons is the usual minimum, with holes drilled in the bottom for drainage.
Why are my cucumbers bitter? Inconsistent watering is the most common cause in containers. Keep the soil evenly moist and avoid letting the pot dry out between waterings.
How much soil does my pot need? Use the calculator above. A true 5 gallon pot takes about 0.7 cubic feet, see how much soil for a 5 gallon pot.
