The great thing about our plants is that when they are feeling sick or stressed, they show us through their leaves. Knowing what each of these signs mean can help us ensure we stop small problems from destroying our harvests and will enable us to get the most from our Airgardens.
There are 3 main ways leaves can show us of problems, they are: 1) colour, 2) shape and 3) damage..
These 3 issues will manifest from either environmental & physical causes or nutritional deficiencies. Below are 2 great illustrations of what you may see in your leaves and the main causes of these issues:
Pests can not only create holes in leaves from eating them, but can also transfer diseases as well. Keep an eye out for mildew, fungus and bacteria which can all be transmitted to other plants close by.
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 5-6 hours of direct sunlight per day.
Over/Under Watering & Dehydration
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 winter conditions.
Nutrient deficiencies can be the cause of many of the following leaf signs below. The good news is that Airgarden nutrients contain all the key macro and micro nutrients needed for your plants to grow big and strong.
However , if your pH is not balanced the plants in your Airgarden will not be able to absorb or utilise these nutrients and may show similar signs below. Always remember to test pH and ensure it is between 6.0 - 6.5 so your plants can access all the nutrients they need to grow big, healthy and fast.
So there you have it. The key takeaway from this is to keep an eye out for your plants and they will keep an eye out for you. happy gardening tribe.
