What Leaves Tell You About Your Plant Health
The great thing about plants is that when they are feeling sick or stressed, they show us through their leaves. Knowing what to look for, and what to do, can stop small problems from developing and destroying our harvests.
There are three ways leaves show us that they’re unwell - colour, shape and damage.
These issues will be caused by environmental and physical factors, or nutritional deficiencies, as per the below diagram:
Pests can create holes in your leaves from eating them, as well as transfer diseases. Keep an eye out for mildew, fungus and bacteria which can all be transmitted to other plants.
Lack of Sunlight
Lack of sunlight can either cause a yellowing or fading of leaves along with leaves becoming droopy. Plants need a minimum of 4 hours of direct sunlight per day to avoid this.
Over / Under Watering
The best thing about your Airgarden is that the watering cycle is automated for you, so this is rarely a problem. However, watering cycles can be decreased from a 15 minute on / 15 minute off cycle to 15 minutes on / 30 minutes off if you are growing in very cold conditions.
Nutrient deficiencies can be the cause of many of the below leaf signs. The good news is that Airgarden nutrients contain all the macro and micro nutrients needed for your plants to avoid this. Nutritional deficiencies will display in the following ways:
However, if your pH is not balanced, your plants will not be able to absorb or utilise these nutrients effectively and may start to show some of the below signs. Remember to test your pH levels each week, and ensure it is between 6.0 - 6.5.
The key takeaway from this is to keep an eye on your plants and be guided by what they’re telling you. Happy gardening tribe!
