Remember to water the container when the compost is dry. Keep topping up with compost until the container is full. Next the potatoes will flower; if these develop into fruits DO NOT eat them- they are poisonous. Stop watering at this point and the potato plants will start to die off above the soil.
Should you stop watering potatoes?
Stop watering potatoes after the foliage turns yellow and begins to die off. This will allow the potatoes to mature to the right stage before harvesting. If you keep watering, the potatoes may mature and then rot in the ground before you dig them up.
How often should you water potatoes in containers?
Water regularly during the growing season – potatoes like plenty of water. Avoid using rainwater from a butt in the summer as this can contain blight spores. Soak the pot thoroughly every two or three days, allowing the compost to almost dry out between watering to promote steady potato formation.
Should you water potatoes every day?
Generally, potatoes need between 1-2 inches of water per week; this could be provided by rain events or you to make up the difference.
