3. Watering and Fertilizing

Watering and Fertilizing

Watering and fertilizing your balcony garden is essential for keeping your plants healthy and productive. However, it is important to adjust your watering and fertilizing schedule during the cold weather months.

Watering:

During the cold weather months, plants do not need to be watered as frequently as they do during the warmer months. The cold temperatures slow down the plant’s growth rate, and the soil does not dry out as quickly. Overwatering can lead to root rot and other problems, so it is important to only water your plants when the soil is dry to the touch.

Fertilizing:

Fertilizing your plants during the cold weather months is also important, but it is important to use a fertilizer that is low in nitrogen. Nitrogen promotes leaf growth, which is not ideal during the cold weather months. Instead, use a fertilizer that is high in phosphorus and potassium. Phosphorus promotes root growth, and potassium helps to strengthen the plant’s cell walls.

By adjusting your watering and fertilizing schedule during the cold weather months, you can help your plants stay healthy and productive all season long.
