Sweet sweet peaches!
I use koolbloom on my fruit trees at about half strength 2nd week of August and half strength 1st week in September by end of September all my fruit are swollen and so sweet makes for easy pickings,, especially the peaches. I have Bartlett pears, Asian pears, 4 type apples trees, cherries, peaches and figs all gets same feeding and are so sweet. This is not the recommended feeding directions per bag just my own preference. A little Koolbloom goes a long so becareful on feeding. Keeps well in cool dark cooler along with all my other plant food. Love the results.
