A few years ago I collected a number of acorns while walking in the park and tried to grow them for fun. As a complete novice I didn't expect them to work and was surprised when they all grew! I gave most to a friend who was growing a wood on her land, and kept two which I foolishly planted in bare ground at the end of my garden, again not really expecting them to 'do'. They are now taller than I am, and it has occurred to me that although I think our garden can accommodate one of them, it may overshadow my neighbour's garden and also two oak trees is an oak too many! I would like to transplant them this winter but will this kill them? I had originally thought I could prune them to a manageable size but I now understand if I wanted to do that I would have needed to grow them in a pot. If I decide to relocate them altogether, would oaks of this size have any value to the council for growing in the park? Any advice very welcome. I live in County Down, NI.
