In my experience, geraniums tend to thrive when they receive a good amount of sunlight but also have some shade to protect them from the intense heat of the midday sun. I have found that an ideal location for geraniums is one that gets morning sun and afternoon shade. This way, the plants can soak up the gentle morning rays, which promote healthy growth and flowering, while avoiding the scorching heat of the afternoon that can sometimes be too much for them.
However, it’s important to note that the amount of sunlight geraniums need can vary depending on the specific type of geranium and the climate of your garden zone. Some geranium varieties, like the zonal geraniums, can tolerate more sun and heat than others. On the other hand, some varieties, like the ivy geraniums, prefer more shade and can actually get sunburned if exposed to too much direct sunlight.
If you live in an area with hot summers, providing some shade for your geraniums can help prevent their leaves from wilting or burning. This can be achieved by placing them in a spot where they receive dappled shade from a nearby tree or placing a shade cloth over them during the hottest part of the day.
Another important factor to consider is the soil drainage. Geraniums prefer well-draining soil, so make sure the area where you plant them has good drainage. If the soil becomes waterlogged, it can lead to root rot and other problems.
Geraniums generally need a good amount of sunlight to flower, but in hot summer areas, some shade is recommended to protect them from the intense heat. The ideal location would have morning sun, afternoon shade, and well-draining soil. However, it’s important to consider the specific geranium variety and your garden zone when determining the amount of sunlight they need.
