Weird tree

Asked June 5, 2015, 3:43 PM EDT

So we inherited this tree when we bought our house in Brighton. And we were wondering if you could tell me: 1. What it is 2. If it should be given nutrients to help it recover from the November frost bite 3. How to prune it Thank you

1. Hard to tell from photos, but best guess is Japanese Umbrella Pine, sometimes called Tanyosho Pine (Pinus densiflora 'Umbraculifera'). Under ideal growing conditions it may become 20 feet tall over many years.

2. Before you fertilize, suggest you rake off/remove rock to a few feet beyond branch extremities. Add more drip lines, as the apparently single one there now is not providing enough water to the tree's roots out away from the trunk.Light fertilization (now or up until early July) might produce a growth response next May. Just sprinkle about 2-3 oz of fertilizer meant for lawns (but without an herbicide) under the tree's branch extremities and water it to dissolve the fertilizer. Then replace rock with 2 inches of bark or wood chip mulch. Pull mulch 4 inches away from trunk.

3. not much pruning needed other than to remove twigs/branches that originate too closely to others on the main trunk; that can be done anytime.
