How to keep pelargonium safe in the summer
Main content introduction: Introduction to the care of pelargonium at home, how to keep pelargonium safe in the summer. The following is an introduction by the editor for the netizens.
Often, flower friends ask what measures should be taken to protect pelargonium from safely surviving the summer? In fact, this is a problem that troubles many flower friends.
However, many flower friends have their own solutions to this problem. I hope everyone can share their experiences and tell how you place your little pelargonium in the summer.
Here are some random notes I've written:
First: Do not let the pelargonium pot accumulate water in the hot summer, and the soil medium should be mixed to dry quickly, such as peat soil + perlite + a small amount of plant ash. Try not to use soil media with good water retention, like Jueyin beautiful soil.
Second: A saying has been repeated many times: the first thing pelargonium needs in the hot summer is ventilation, the second is ventilation, and the third is still ventilation.
First of all, for flower friends with a courtyard, it is easy to achieve ventilation. Pay attention to keeping pelargonium semi-shaded and not let the roots of pelargonium be in a water-logged environment, basically ensuring safety. In the summer of 2006, during the hottest days in Beijing, I saw several pots of hanging pelargoniums blooming in the courtyard of Hai Ming, which made me feel that connecting with the ground is really different. Apart from surviving the summer, pelargonium is actually a very easy plant to care for, so outdoor flower friends don't need to read further.
Next, for those living in apartments with good ventilation from north to south, due to the good ventilation conditions, placing pelargoniums on the north balcony (preferably unenclosed) to avoid direct sunlight and controlling water and fertilizer can basically ensure no worries. (Flower friends who place little pelargoniums on the outdoor window sill are also classified as such)
Lastly, the most challenging situation for pelargonium is living in a poorly ventilated enclosed south-facing balcony, which can easily lead to blackened stems and complete collapse. Since I plan to write an article summarizing my own summer survival strategies this autumn, I won't write much now. Let's take a break here and copy a previous post I replied to:
My pelargonium summer survival strategy:
1. Use wooden pots (can't guarantee 100% survival, but 90% is not a problem)
2. Drill more holes in the plastic pot for aeration, allowing the soil to dry quickly
3. Use a藤条小筐 (be careful not to let water flow everywhere)
4. Other methods, such as one that imitates the root irrigation method of clematis and another that imitates the water absorption method of African violets, will be summarized after practice in the autumn.
Here are some summer survival experiences of other pelargonium enthusiasts, hoping to give everyone some inspiration:

1. Do not expose to direct sunlight 2. Ventilation 3. Do not let water accumulate.
For me, it's definitely not possible to place it in the current location in the summer, as that spot is right at the southwest corner of the balcony, with direct sunlight and high temperatures. I plan to put it all along the wall of the balcony, where there should be ventilation when the window is open. The platform where the pelargonium is placed will be used for heat-resistant flowers like eating and relaxing daylilies...

It will die without watering, can you really not water for three months? If you don't water for the first month, the roots will dry and wither~ If you show a little mercy and water a bit in the second month, without roots to absorb it, the bubbles will naturally rot, and long-term lack of watering will either cause black rot or turn into firewood~ Hahaha~
Ventilation is the solid principle~~~~~ Not necessarily shady, cool, or less water~~~~ Keeping ventilation and a bit of shade would be perfect~~~~~
Can you put it outside? Even if it's a south window, I've tried it, and it didn't die, just a bit sorry~
If it really doesn't work, you can learn from Bangma and put it on the window of the corridor~ That should be ventilated and shady, right~
If it really doesn't work, here's the ultimate solution: take it to D5's house or Bangma's grandpa's house for foster care in the summer~~~

I also have a southwest balcony. Most of the black rot last year was because I wasn't at home for more than a week, and no one watered. When I came back and watered, they were gone...
In the previous year, my pelargoniums were either placed outside the window or near the gauze window. There were fewer cases of black rot.
Find a "corner" in your house that is not directly exposed to the sun but has good air circulation, or at least give it some shading to keep it cool at noon~

Did it get rained on? Especially those heavy downpours or continuous rain? After the rain clears and the temperature rapidly rises, with high humidity and wet soil, pelargoniums are prone to black rot. Even without rain, the continuous high humidity and heat of a sauna-like weather are also not good for pelargoniums! Be careful when watering in such weather!
I have a Ligularia kaempferi that I keep on the indoor windowsill during the summer for reference:
As everyone knows, Ligularia kaempferi is more prone to black rot than pelargoniums, especially in the hot summer!
1. Bottom watering, keeping the upper part and the surface of the pot dry; (but the disadvantage of this method is that it can cause salt accumulation in the middle soil layer, which can easily burn the roots over time, so I don't use it except in the hot summer)
2. Ventilation! If the natural conditions are not good, consider artificial methods: such as using a fan
3. Regularly spray fungicides or potassium permanganate
The pelargoniums are all kept on the south-facing balcony of a high-rise building, but the windows can be opened, and the ventilation is good; so these methods have not been used on pelargoniums
Before last year, I used cheap potting soil I bought early, probably domestic peat or humus soil; in the summer, I watered normally, watering when the soil surface was dry, about every two or three days; I felt that surviving the summer was very easy
Last year, I switched to Da Han peat soil and couldn't water properly. Last August, when it was continuously rainy, I intentionally prolonged the watering interval but still flooded the roots, losing several varieties I propagated in the spring, including the famous Apple Bowl. But it wasn't because of black rot
I seem to have a problem with Da Han peat soil, always unable to master the right amount of water. Last autumn, I changed all the upright pelargoniums back to the old potting soil; the trailing ones were kept in the relatively light peat soil because they had to be hung. Now the upright ones are growing and flowering much better than the trailing ones; I plan to change the peat soil of the trailing ones after this flush of flowers!

Last summer, I had a fan on during the day (set for a few hours at a time) and turned on the air conditioner for a few hours after work in the evening. I watered after 10 p.m., almost once a week, and none of them died.

An early pelargonium enthusiast's experience of "watering a small amount along the pot wall, allowing the water to quickly reach the bottom of the pot" is a simple and effective method if there are not many flowers.

My greenhouse is equivalent to a south-facing balcony! My hanging pelargoniums are placed in the outdoor garden and have safely survived the summer for several years.
In Beijing, August is a difficult season for upright pelargoniums. Good varieties are kept in the greenhouse with controlled water. Strong varieties still grow well in the garden.
I personally feel that pelargoniums are afraid of water and high humidity. Upright pelargoniums do well in small pots!
In my garden, the upright pelargoniums in the ceramic pots are used as pot covers. The large ones directly planted have half the pot filled with ceramsite, or two plants.
Declaration, serious declaration, the above are all the experiences of other flower friends that I have copied, hoping to be helpful to everyone!
