If you end up with some extra tree tubes after you're done protecting your newly planted seedlings, chestnuts and acorns, here are a couple of ways you can put those tree tubes to use:
1. Use tree tubes on naturally regenerated seedlings (volunteers) that you want to favor and protect
2. Use tree tubes on stump sprouts (suckers) that grow after an older tree dies or is harvested
Obviously growing from seed or re-sprouting from an existing root system are two ways trees have been reproducing since the dawn of time. But keep in mind that only a tiny percentage of those naturally regenerated trees ever survived to reach maturity - and today's volunteer seedlings or sprouts face more dangers in the form of record high deer populations and dozens of invasive weed species than ever before. Covering them with Tree Tubes not only shields them from deer browse, it makes it easier for you to locate those special young trees and give them some weed & brush control.
So you don't always have to plant a tree to grow a tree. Sometimes you can simply take what Mother Nature starts and give it a helping hand.
