Q.fertilizing
Can I apply Milorganite within one day of applying blood meal to my garden, or will it be too much nitrogen?
What are you fertilizing? What is the nutrient level in your soil?
Have you had a soil test done on your soil? Are you trying to raise the nitrogen levels in your garden?
Nitrogen is certainly beneficial to your garden and necessary for your plants to grow healthy, but excess nitrogen can be a detriment inhibiting formation of flowers, fruits and vegetables.
Excess nitrogen can burn and even kill your plants.

In my opinion, alway apply nitrogen in lighter formulations, you can always reapply! You can't take it back--very easily!
