With its graceful posture and beautiful flowers, potted Begonias are deeply loved by flower enthusiasts. The low temperature and dry environment in winter pose higher requirements for the maintenance of potted Begonias. This article will introduce you to the winter cultivation methods of potted Begonias in detail, helping you easily get through the cold winter.
Light management1. The light is weak in winter, and potted Begonias need plenty of scattered light. You can place the pot in a well-lit indoor area, avoiding direct sunlight.
2. If there is not enough indoor light, you can use a plant growth lamp to supplement the light to ensure the normal growth of Begonias.
Temperature control1. The suitable growth temperature for potted Begonias in winter is between 5℃ and 15℃. Too low temperature will cause the leaves of Begonias to turn yellow, fall off, or even die.
2. If the indoor temperature is too low, you can take the following measures:
(1) Place the pot near the heater, but maintain a certain distance to avoid high temperature damaging the Begonias.
(2) Use insulating materials such as an insulating cover or a cotton quilt to insulate the pot.
Watering management1. The water requirement of potted Begonias decreases in winter, and watering should follow the principle of "watering when dry and damp when seen".
2. When watering, the water temperature should be close to the room temperature to avoid excessive temperature differences that could harm the Begonias.
3. After watering, promptly remove any accumulated water in the pot to prevent root rot.
Fertilizing management1. Potted Begonias grow slowly in winter, and fertilizing should focus on applying thin fertilizers frequently.
2. You can choose a compound fertilizer with low nitrogen, high phosphorus, and potassium, applying it every 20 days.
3. After fertilizing, water promptly to help with fertilizer absorption.
Pruning management1. Winter is a good time to prune potted Begonias, removing diseased, weak, dry, and dense branches to facilitate ventilation and light.
2. After pruning, apply gardening ointment or wood ash to prevent wound infections.
Pest and disease control1. Potted Begonias are prone to pest and disease attacks in winter, so it's important to observe and control them in a timely manner.
2. Common pests and diseases include aphids, red spiders, and scale insects, which can be controlled with insecticides.
3. When controlling pests and diseases, be mindful of safety to avoid harming people and the environment.
Winter maintenance of potted Begonias requires attention to aspects such as light, temperature, watering, fertilizing, pruning, and pest and disease control. Mastering these cultivation techniques will ensure that your potted Begonias can get through a warm winter and welcome a beautiful spring.
