A tree in its second year is usually still regrowing roots lost at planting, so it needs deep weekly watering, an uncovered root flare, and stakes removed once it stands alone. Heavy feeding is best avoided, since water uptake is usually what limits a young tree.

Why can a tree still struggle a year after planting?

Because its roots are still catching up with its canopy. Establishment, when new roots can supply the whole tree, takes about 1.5 years for a 1 inch trunk and about 9 years for a 6 inch trunk.

How should a tree be watered in its second year?

Deeply and weekly until the roots are established, with a soaking rain of more than 1 inch in a day standing in for one watering. To release that water slowly at the roots, a Treegator Original Slow Release Watering Bag around a 1 to 8 inch trunk is filled once or twice a week, holding about 15 gallons per fill on a 1 to 2 inch trunk.

How can a tree planted too deep be spotted?

By checking that the root flare, where the trunk widens into the roots, sits at the soil surface. A buried flare restricts the oxygen and water the roots take up.

When should stakes come off a young tree?

After one growing season, in fall. A tree that still shifts in the soil is retied loosely for one more season, since staking too long can girdle the trunk or weaken the stem.

Should a struggling second year tree be fertilized?

Only lightly, with a low nitrogen formula. Where a young tree still looks stressed in summer, TreeHelp Therapeutic Tree Fertilizer, a slow release blend with limited nitrogen, can be applied to support root development.

Frequently Asked Questions

Should tree ties touch the bark?

No. Rope, wire, or cable should never contact the trunk, and anything that does touch it should be broad and smooth.

Can mulch around a young tree be too deep?

Yes. Deep mulch can cause roots to dry out, so a moderate layer kept away from the trunk works better.

Where is trunk diameter measured on a larger young tree?

Twelve inches above the root flare for trunks over 4 inches.

How much therapeutic fertilizer does a young tree need?

Less than a full bag. One bag treats one large tree or 2 to 3 smaller or newly planted trees.
