I am currently landscaping my yard. I plan on completing everything with the exception of planting a few small, narrow trees around the perimeter. I will be doing that next year.
While everything is a mess now, I am considering digging the holes for the future trees, putting ~5 gal buckets in the holes and then backfilling. My thought is that this will make it easier to come back next year, pull out the buckets, make any necessary small adjustments to the size of the hole and plant the trees without having to make a big mess.
Is this an OK idea? Are there any problems with it? The only problem I can think of is that the subsoil is heavy clay which could really stick to the bucket, so getting the bucket out come next year could prove to be a challenge.
