In that case go ahead and enjoy the blossom, then pick the fruitlets off afterwards. The reason that I don't think you have to worry about the blossom distracting the tree from growing is that many apple trees will naturally drop some fruitlets in June if they realise they have set too many - so you are just helping the natural process. MM111 has a reputation for being the opposite of precocious so you are doing well to get blossom at this age.

Ok, thank you for your replies. Since the red rose is on just a small branch coming from the tree, should I cut that branch off? (as to avoid more red flowers in my all white garden lol) Will the rest of the branches that now have white flowers eventually get red ones? I have very limited knowledge on grafting so not sure how it effects a whole rose plant. Thanks again!

I have the feeling that you cut off the bloom possibilities when you cut it down last fall. The blooms on the native wisteria I have come from the places where there were leaves last year (I hope that makes sense), so if you cut off almost all of the branches/growth with leaves, there will be no blooms. Mine does throw out blooms a couple more times over the summer; not as huge a display as in the spring, but still, blooms are blooms. I'm sorry that you had to cut it down to save it, but it will make it up to you next year.

You could try adding Potassium Silicate to your soil. "What does potassium silicate do for plants? How Potassium Silicate works. Plants take silicon into their walls, making tougher cell walls. The assimilation increases rigidity and strength, to support, larger flowers and fruits. It also strengthens cell walls of plant stalk and stem to hold additional weight and support big buds.May 23, 2016" https://www.google.com/search?newwindow=1&sxsrf=ALeKk03PDgTt8kXFCiowiS_Q9fKh4I1MBw%3A1593635432580&source=hp&ei=aPL8XufdIMWGtQaniprICg&q=silicon+for+plants&oq=silicon+for+plants&gs_lcp=CgZwc3ktYWIQAzICCAAyBggAEBYQHjIGCAAQFhAeMgYIABAWEB4yCAgAEBYQChAeMgYIABAWEB4yCAgAEBYQChAeMggIABAWEAoQHjIGCAAQFhAeMggIABAWEAoQHjoECCMQJzoFCAAQsQM6BQgAEIMBOgQIABAKUKUaWPBgYKZtaABwAHgAgAFSiAG6CpIBAjE4mAEAoAEBqgEHZ3dzLXdpeg&sclient=psy-ab&ved=0ahUKEwjnse7O8qzqAhVFQ80KHSeFBqkQ4dUDCAk&uact=5
