|About 5 years ago I planted a dozen pear trees. They were all the same variety, and I bought them all at the same time from the same greenhouse, planted them at the same time, and cared for them all the same way. They are all planted in the same area.
Why don't they all grow at the same rate? Over the five years, 10 have done well, and 2 seem stunted, and hardly grow at all. What could cause this, and what can I do about it?
|How perplexing! It is possible that for some reason the two have not rooted properly, or possibly their grafts are not perfect. It is also possible that unbeknownst to you there is an underground, invisible difference in their growing conditions such as bedrock interfering with their growth. Without digging them up to investigate to learn the cause, it's a bit difficult to know what to suggest. You mgiht wish to contact a professional arborist for an on-site opinion, or your County Extension might have some ideas. Their telephone number in Binghamton is 772-8953.
I hope you solve the mystery!
