How does geranium survive the summer?
Plant management tips, related experiences about geraniums, how geraniums survive the summer, let's learn about it together.
How geraniums survive the summer is a困扰 for many geranium enthusiasts. The methods for geraniums to survive the summer below are a collection of successful local experiences from last year's high-hand gardeners, which are practical, with temperatures of 37-39 degrees Celsius lasting more than a month in summer.
A brief summary of the precautions for the summer of upright varieties: taking the central plains region as an example (when the maximum temperature during the day exceeds 33 degrees Celsius)
1. To survive the summer, it is necessary to minimize the consumption of nutrients, especially for young and medium-sized seedlings, remove buds and flowers.
2. Cut off old leaves and retain vigorous ones.
3. Suspend the application of nitrogen fertilizer, reduce the application of phosphorus fertilizer, and apply potassium fertilizer normally; suspending nitrogen fertilizer is to prevent providing nutrients for new leaves in high temperatures, reducing phosphorus fertilizer is to inhibit the plant from budding, and applying potassium fertilizer normally is to strengthen the plant, promote root growth, and enhance resistance.
4. Supplement physical strength: (at night) spray "glucose solution" with a concentration of 2.5% on the leaves, the next day, rinse the leaves with clean water. Ensure good ventilation so that the moisture on the leaves evaporates quickly without accumulating.
5. Avoid frequently spraying water on the leaves of young and medium-sized seedlings during extreme heat, although it can achieve the purpose of cooling, if the moisture does not evaporate in time, high temperatures can cause the leaves to accumulate water and rot, affecting the health of the plant. Try not to splash water on the leaves when watering.
6. Use fungicides such as carbendazim, chlorothalonil, and thiophanate-methyl alternately during persistent high temperatures or after rain to prevent resistance, about once a month; if potassium permanganate is available, it can be diluted to a light purple color and applied directly to the roots to enhance resistance.
7. Lighting: Try to provide shade, and never let the potting soil become very hot. There should be about two hours of direct sunlight in the morning and evening. For balcony gardeners who cannot get direct sunlight from the overhead sun in the summer, it is fine to place them in a bright area.
8. About the choice of pots: Use smaller pots for planting, and do not use pots that are too deep, ensuring that moisture can alternate between wet and dry.
9. Ventilation is very important. For friends with limited indoor ventilation, even with air conditioning, it is best to use a fan, which can set the air conditioning temperature a bit higher to reduce energy consumption and ensure ventilation.
