About 4 years ago I came across an ad in a gardening magazine for fast growing, disease resistant, and best of all CHEAP trees. I had been wanting to plant trees down our lane on both sides but could never afford to buy 30 trees. These trees were Hybrid Poplars and I'm sure most of you have read about them. They are the shade tree hybrid poplar, not the type that is used as a privacy screen or wind block. Well, the trees are 4 years old going on 5 and they are monsters! Long, tall, skinny trees. I can't believe how tall they've gotten in just 4 years. Does anyone know if they will fill out and be nice looking? Have I made a mistake planting this tree? It kind of makes me nervous right now, like the skinny things could blow over at any time. I'm wondering if I should cut them down now, while it would not be so difficult, or let them go for another few years and see how they turn out. You know the old saying, You get what you pay for...I'm hoping that's not true in this case. What would you do?
