Bulk plant cells

Hi,
I have levelleled an area 5m square to start a tree nursery because we seem to have literally hundreds of saplings sprouting out of the ground this year, Lime, Maple,Ash,Scots Pine Horse Cestnut, etc...
Is it the bad winter that's caused this rush of growth.?
Rather than planting them straight into the ground I was thinking of planting them in those little cells.
However, bearing in mind I have to get hundreds, Dobbies doesn't seem the most economical place to get them.!
Where do I get these cells at a reasonable cost.?
Is there anything better than these cells, I want them to get a couple of feet high before I move them to their final resting place.

thx
Howard

 

Assuming they are only about 2 to 3 inches tall I would be inclined to put them in 3 inch pots. Try the plantpak or wilkos websites for bulk buys.:thumb:
