When it comes to plants I admit I look for plants that will exist on sunlight and water and little else.
Well, I used to. Right now the 5 plants in my home are all fake so I guess they don't need the water and sunlight either!
I copied down this old recipe in a moment of positive thinking when I decided I would mix up a little 'pick me up' for my plants.
Plant Food
In a gallon jug of tepid water, mix 1 teaspoon each of;
Epsom salts
saltpeter
baking powder
and 1/3 teaspoon ammonia.
This is a complete plant food and should be used only once every 4 to 6 weeks. It can be stored. Shake well before use.
