- Required
Cucumbers are container-suitable. The verified minimum is a 5-gallon pot per plant; bigger pots dry out slower and are more forgiving.
- Container plants dry out far faster than the ground โ check daily in summer and water when the top inch is dry. We don't publish a fixed gallons-per-day figure: pot size, material, mix and weather all change it.
- The pot MUST have drainage holes โ standing water rots roots faster than drought hurts them.
