Good morning we planted these Swedish aspen trees in 2013 and this one isn't doing well this year. I did a scratch test on it and its green, it does appear to have buds on it but still no leaves? I just hammered fertilizer spikes in on July 8th. Our neighbor last fall drained his hot tub which has potentially wrecked part of his grass, did the chemical disturb our trees roots as well ? I am reaching out for some advise. Please let me know if you need more pictures. Thanks for your time in this matter. Brent
