Effect of rain on 5:1:1 and gritty mix fertilizer program
Forgive me if this has been addressed. I have searched for this answer and have silently been following years of posts on these forums for months.
I have a couple of figs and dwarf burning bush plants in Al's gritty mix or 5:1:1 mix outdoors (along with indoor plants).
I have been watering all of my plants with Foliage Pro as suggested and everything is looking great (except what the rabbits have hit).
My question is how I should modify my fertilizer application to account for all of the spring rain. Since all nutrients are provided in a readily available ( and more easily leeched) form, I am not sure how I should modify application from the recommended amount.
I have been watering twice a week, no matter how much rain, since I water both indoor and outdoor containers with the same solution (1/2 weekly dose).
Should I be using a more concentrated doseage outside to account for the rain?
I realize that fertilizer and micro-nutrients are not literally "washed out" by the rain as they have differing levels and modes of staying inside the container. But it seems to me that some leeching must occur.
