How Does Extreme Heat Affect Succulents?
Excessive heat can cause the soil to dry out rapidly, making it challenging for the plant to maintain moisture.
Additionally, high humidity levels can promote fungal growth, which can harm succulents. Lastly, overwatering is a common issue during the summer, as many people assume plants require more water in warmer weather which can also be detrimental to succulents.
How Much Sunlight Do Succulents Need?
Extreme temperatures are harmful to succulents, but they do need some sunlight.
Normally, succulents require at least 4–6 hours of sunlight every day to thrive. If your
succulents do not receive enough sunlight, they may start to wither. You will notice their
leaves turning yellow and the plant beginning to sag. Therefore, it’s important to expose
your succulents to just the right amount of sunlight; not too much or too little.
Succulents are hardy plants, but extreme heat and intense sunlight can cause stress. Here
are some common signs that indicate your succulents may be suffering from too much
heat:
• may produce brown or reddish spots. Adjusting the plant's location to create shade
can help prevent additional harm.
• Excessive heat can cause dehydration. If succulents appear wilted or shriveled, it
could be due to a lack of water or excessive sun exposure.
• High temperatures can stress succulents, causing them to drop leaves. Check for
excessive leaf drop, which may signal the need for a more shady area.
• Intense sunshine can cause succulents to lose their bright color, giving them a pale
or bleached appearance. This is a typical indication of sunburn.
• Too much heat combined with overwatering might cause root rot. If the succulent's
stems or roots grow soft or mushy, alter the watering schedule and ensure good
drainage.
How To Care for Succulents in Extreme Heat in Australia?
• Watering : Watering on early morning. (Succulents don’t like to be wet when really
hot outside.) they will absorb water into their root what they need and keep their root
cool. Or late afternoon
• Succulents size: You have to plant succulents in cooler times in the year, when they
grow they acclimate to those warmer temperature condition. When succulent size
smaller, it cannot bear hot temperature.
• Shade Cover: Placing smaller succulents next to larger succulents will help to
provide a natural shade all the time.
• Watering Frequency: It is important to water succulents frequently but need to make
sure to allow potting media to dry between two watering cycles.
• Training: Gradually introduce your succulents to the direct sunlight (increasing an
hour or so every couple of days), most succulents will tolerate full sun most of the
day.
• Healthy roots: Healthy succulent roots store water, resist heat stress, insulate,
retain moisture, and adapt, crucial for surviving extreme heat conditions.
