We regularly collect natural material, with a permit, from sites where seedling regeneration is unwanted. Opportunities to collect from building and road development and garden clearance are also sought.

Trees are well established in wooden training boxes with some pre-training done. The trees currently available are Blauuws Juniper, Crab Apple, Field Maple, Hornbeam, Larch, Mugho Pine, Oak, Potentilla, San Jose Juniper, Scots Pine and Yew.
