Fertilizing with Gritty Mix
I need to pin down some things about fertilizing with gritty mix.
Here's the info I have so far: "Add 1/4 tsp of Epsom salts per gallon of fertilizer solution every time you fertilize at recommended strength, or 1/8 if you fertilize at 1/2 strength, or a pinch if you fertilize every time you water at 1/8 - 1/4 strength (depending on how robustly the plant(s) is/are growing. You can add white vinegar to acidify, 1-2 T in a gallon of water."
I will be using the Foliage-Pro 9-3-6. Here are my questions:
1) Re: blueberries, because they like a nutrient-poor soil, will it be enough to fertilize only once a year, in the spring? (I've seen that recommendation but am worried it may not be enough.) If only once, then should it be at full strength or would that be too much?
2) Re: my fig, I thought I would follow the "pinch" of fertilizer with each watering during the spring and summer and then nothing in the fall and winter. Is that right, or do I stop when the fruit buds appear?
(For those who remember my mini-balcony aspirations, I don't need to ask about the Carrie mango I had planned on because I think that was taking on too much, too soon, for someone still near the bottom of the learning curve. Maybe next year.)
