I hope they will get bigger next year. I bought some of the tallest ones last year to put in the back and they aren't half as tall as when i bought them.I thought maybe they needed to be fed.We have had so much rain that any liquid fertilizer was out of the question.I'm not sure what they should be fed with 20-20-20 or 15-30-15?? I have put out some osmocote but prefer liquid.
