Don't let this happen to you

Thin Your Fruit Trees! Why? Because thinning your fruit trees allows remaining fruit to develop into its full potential size. In the picture above, the fruit are too close together, so these Saturn Peaches will never be at their full potential size and flavor. Thinning fruit helps reduce the chances of overloaded branches being so weighed down that they break. If the fruit is touching chances are higher for pest and diseases to spread, such as Apple Scab and Brownrot. Thinning of fruit should typically be done about 35-45 days after blooms have disappeared, or when fruit is about an inch in diameter. (But, better late then never!)

I admit when I thin out the fruits here at the nursery it is a bit hard. Because I am taking off the fruit that has formed, it almost seems like a waste of fruit! But, I know in the end it's what is best for the health of the tree and the fruit.
