I had thought about putting my indoor medic garden outside for the duration of the thunder storm, but decided against this as some of the plants are not ready to get bashed about by the huge rain drops that often fall during a thunder storm.
Instead I have placed a container outside to collect the rainwater that's falling during the thunder storm. I will use this to water my indoor plants with.
How do Plants Benefit From Lightning?
Nitrogen is a very important for plants, it encourages healthy root and plant growth, and encourages the plant to produce chlorophyll.
If you have any plants that are not looking healthy, have yellowing leaves, and stunted growth, then your plants may well have a nitrogen deficiency.
It does not lightning much around here though, so what about those times when you cannot use the nitrogen rich rainwater?
Easy DIY Organic Nitrogen Fertilizers
One is to use coffee grounds sprinkled on the soil, or mixed in the top layer of soil. I don't do this often, just every few months or every quarter. Or if the plants are looking sad and like they need a boost.
Another way is to use a comfrey infusion, or tea. Make this with fresh or dried comfrey leaves, tear them up and place in a pan with boiling water. Leave to infuse and cool, then decant into bottles for watering the plants with. You can make this without boiling the leaves, just leave to infuse for a few weeks in a bucket - but this does smell!
Comfrey is an awesome plant that has a lot of medicinal uses, which I will be covering on the main website soon. It is even said that growing comfrey with other plants will help them retain nitrogen in the soil.
