How many times have we gone to give our flowers or veggies a little food. We spend more time in preparation than actually feeding.
Here is a quick way I feed my plants.
Sprinkle the plant food (blue) over the soil and leaves of the plants being fed.
As you can see by the pictures, just sprinkle, do not over load the ground with food.
Then water by sprinkling. Make sure all of the food (blue) is wet, so it is not blue anymore. After the that, water normally.
I have been doing this for years and it works great every time.
This year I have decided go with the container garden idea. But it works just as well for traditional gardens.
