Discussion on Pelargonium Summer Survival Issues for Flower Friends
Core Guide: This article focuses on the content related to Pelargonium, discussing summer survival issues for flower friends, offering some useful tips and knowledge. It is recommended to save this for future reference!
When it comes to Pelargonium surviving the summer, the main points can be summarized in six words: ventilation, shade, and rain avoidance. Putting aside the regional and home environments of different flower friends, it is essential to create an environment with good ventilation, shade, and rain avoidance for Pelargonium, no matter the setting.
Regarding flower pots: The best options are wooden, clay, ceramic, or purple sand pots, which have good breathability. If using plastic or glazed pots, special attention must be paid to the watering amount! Also, remember to use large pots for large plants and small pots for small plants; avoid using large pots for small plants. If only a small plant is in a large pot, less soil should be used.
About the medium: The soil medium should be a mix that dries quickly and does not accumulate water, such as peat + perlite + a small amount of wood ash. Avoid using soil mediums that retain too much water, like beautiful soil. If your medium retains a lot of water, consider changing to a breathable pot or inserting hollow items like bamboo stakes into the soil near the pot edge to aid in ventilation.
About watering: This is a very troublesome issue.
1. Watering time: It's best to water in the evening or early morning, mainly waiting for the soil temperature to drop before watering. The water should be left to sit for a while and should not be used if it has a significant temperature difference with the air.
2. Watering methods: In summer, there are methods like the pot immersion method, wick absorption, small amounts of water along the pot wall, root irrigation through a tube, and the cotton strip water guidance method. Try to reduce the overhead watering method. If the top of the pot has water but the bottom roots do not absorb it, then it's time to prepare for the plant's demise. The drawback of the pot immersion method is that it can cause salt accumulation in the middle soil layer, which can easily burn the roots if used for a long time, so it is only recommended for summer.
3. Watering amount: Personally, I think it's better to keep the plant's roots moist while keeping the upper part and the surface of the pot soil dry. Water control is necessary in summer, but the amount of water control depends on the size of the plant and the amount of medium, which is not standardized.
About pruning: Remove excess leaves to ensure ventilation between leaves and reduce nutrient consumption. Promptly remove any dead flowers and yellow leaves from the plant. Be especially careful to avoid damaging the main stem during pruning to prevent fungal infections.
About disinfection: To prevent stem rot, you can water with carbendazim, root rot control, or potassium permanganate every 3-4 weeks to prevent bacterial infections.
About fertilizing: Stop fertilizing in summer. If fertilizing is necessary, it should only be with a very dilute solution. On the hottest days, new leaves of Pelargonium may turn white, which you can ignore or water with ferrous sulfate every 3-4 weeks, following the dosage instructions, and the new leaves will turn green.
About diseases: The main disease in summer is stem rot. If it appears, immediately discard the seedlings and soil. Other diseases include leaf spot and flower wilt, which should be promptly removed to prevent infection spread and treated with Bordeaux mixture.
About mulch: In summer, add some mulch to the pot soil to reduce water evaporation, prevent direct sunlight on the soil surface, and isolate bacteria on the soil surface. Choose breathable materials like lava rock or ceramic granules, and avoid using materials that are prone to虫 infestation or solid and non-breathable stones like bark.
About types: Pelargonium is currently divided into upright, hanging, and large-flowered types. Relatively speaking, upright types are more prone to rot, so watering amounts should also be adjusted for different types.
In summary, flower friends need to explore their own care methods based on their micro-environment and plant conditions. Never follow instructions blindly. Always remember: life is more important than beauty. If you can help Pelargonium survive the hot summer, it will reward you with another brilliant autumn and spring.
If the daytime temperature exceeds 35 degrees Celsius and the nighttime temperature exceeds 22 degrees Celsius, it is recommended to keep the plant in an air-conditioned room (especially for valuable varieties) room and add a fan to keep it cool and worry-free.
