Place the potato bag in a bright, frost free position, water regularly, and wait for your plants to grow. Feed potato plants every other week with potato fertiliser and water the bags whenever the compost shows signs of drying out.
How often should I water potatoes in bags?
Do not let the soil dry out when growing potatoes. During hot and dry summer days, potato plants should be watered once every 2 to 3 days. During cooler days with rainfall, potatoes may not need watering at all. Another thing to consider is the type of planter you are using.
Should I 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.
Do you continue to water potatoes?
Stop watering your potato plants about 2-3 weeks before harvest, or when you first see the foliage on the plants starting to turn yellow. Make sure to harvest your potatoes on a dry day when the soil is dry—harvesting potatoes when wet or damp can cause the potatoes to rot more easily in storage.
