In a winter greenhouse, watering needs can vary depending on the type of plants and environmental conditions. During colder months, plants generally require less water because the cooler temperatures slow their growth and reduce evaporation. It may be helpful to monitor soil moisture rather than sticking to a set schedule.
Check the top inch of soil regularly to see if it feels dry before watering. Overwatering can lead to root rot, especially in the colder, less active months. Greenhouses with high humidity may also reduce the need for frequent watering, so it's essential to maintain balanced humidity levels. Plants like cold-hardy vegetables and herbs may require watering every few days, while slower-growing plants may need even less frequent watering.
