Canna, a plant full of life and vitality, has become a favorite of many gardening enthusiasts with its unique form and beautiful leaves. But you know what? For canna to thrive in a pot, there are some key conservation techniques that need to be mastered. Today, let's explore the things about raising potted canna, so that your green baby can bloom in a small pot.
1. Choose the right potting soil.
Potting soil is the foundation for the growth of canna, so choosing the right potting soil is crucial. It is recommended to use flower pots with good permeability, such as ceramic pots or plastic pots. In terms of soil, potting soil composed of humus, garden soil and river sand in a ratio of 3:2:1 is the most suitable. Such soils are both nutrient-rich and have good drainage properties.
2. Reasonable fertilization.
Canna needs plenty of nutrients during its growth. During the growing season, apply well-rotted organic fertilizer, such as well-rotted chicken manure or sheep manure, every half month. Before flowering, appropriate application of phosphorus fertilizer can promote flower bud differentiation. Entering the winter, the canna grows slowly and should be fertilized with less or no fertilization.
3. Watering in moderation.
Canna prefers moist environments, but avoids stagnant water. During the growing season, keep the potting soil moist to avoid root rot caused by overwatering. When the summer temperature is high, you can increase the number of watering times appropriately to keep the leaves moist. In winter, the number of watering should be appropriately reduced to facilitate the safe wintering of canna.
Fourth, the light is sufficient.
Canna prefers a sunny environment, but is also tolerant of semi-shade. During the growing season, canna should be placed in a sunny place to ensure that it receives sufficient light. When the sun is strong in summer, it can be properly shaded to avoid sunburn of the leaves. In winter, it should be placed indoors in a sunny place to avoid affecting growth due to insufficient light.
5. Maintain a suitable temperature.
The suitable growing temperature for canna is 20-30 degrees Celsius. During the growing season, keeping the room temperature within a suitable range is conducive to the healthy growth of canna. When the temperature is high in summer, it should be ventilated or placed in a cool place to avoid the high temperature affecting the growth. In winter, you should pay attention to keeping warm and keep the room temperature above 10 degrees Celsius to avoid frost damage to the canna.
6. Pest control.
Canna is sometimes infested with pests and diseases, such as leaf spot, aphids, etc. As soon as signs of pests and diseases are detected, control measures should be taken immediately. For leaf spot disease, 50% carbendazim wettable powder 1000 times can be sprayed for control. For aphids, 2000 times of 50% anti-aphid wettable powder can be sprayed. At the same time, strengthen ventilation and light to improve the disease resistance of canna.
In addition to the above key conservation points, there are some details to pay attention to. For example, regularly prune the yellow leaves and residual flowers of the canna to maintain its beautiful plant shape; During the flowering and fruiting stages, the branches should be properly supported to prevent them from lodging; Deal with fallen leaves and residual flowers in a timely manner, keep the potting soil hygienic, etc. Through these meticulous care measures, I believe that your potted canna will definitely thrive and add vitality and vitality to your home life.
