Advice on hot and droopy plants
If your plants are looking a little wilted right now, don’t worry! Plants like to be filled with water to keep their structure, and when it’s hot that water evaporates.
Just give them an off-schedule watering and they’ll be right as rain in no time! Be careful not to flood them - plants don’t like extremes.
