Dig over the area thoroughly, not just the hole you're planting in, add some composted material and some fish blood and bone or bonemeal. Beech does not like heavy, wet soils, so plant somewhere suitable. But the most important thing is water - for its first two years, you must make sure it gets at least 2 gallons a week during dry spells.

I agree with Bamboo's suggestions. the soil around the hole should be enriched too to help the roots grow out.

what a lovely gesture.

Thanks very much, great advice, I will do just what you have suggested. Thanks. x
