A general rule is that trees need 10 gallons of water for each inch of the tree’s diameter. For large trees, that can amount to approximately 160 gallons of water or more. Watering big trees to this extent can take quite a bit of time using a hose. For this reason, you may consider installing a soaker hose or sprinkler system to make the job easier.  

You can use the formula mentioned earlier to calculate the depth of tree roots. Each inch of width of a tree trunk translates to six inches of depth within the root system. Large trees extend anywhere from 2 to 6 feet into the ground, with some magnificent specimens going even deeper.

The best time to trim trees is in late fall through winter when the tree has slowed its growing for the year. Cold weather stops insects and fungal growth from attacking a new tree wound. Summer and fall are considered the worst times to trim trees, but it’s permissible in certain scenarios, such as tree disease, damaged branches, or small, aesthetic cuts.

It’s possible to transplant trees as tall as 50 feet when an experienced tree planting service uses the right equipment. However, a tree with a trunk larger than two or three inches in diameter needs to be handled by a professional in order to yield successful transplanting results. Consulting a tree planting professional is the best way to tell if your large tree can be safely transplanted.
