They grow upwards and become drawn and do not reach their natural spread.
As close as possible.
None should be planted close to another. Like trees, their toot systems go deep and wide.
Anything but trees should be ok.
Great trees for hanging a hammock include maples, elms, oaks, lindens, and sycamores. Make sure to plant them close enough together and wait till their trunk is nice and strong.
It won't le me edit or elaborate my question so I'll expand it here: What happens if you plant several different species of trees close together, assuming you have a way to provide for increased mineral and water needs? For example; say you plant one each of birch, elm, and cherry sapling within about a square foot of space. As the trunks grow and thicken, will they essentially merge into one strange tree with three distinct genetic sets?
fish is a swimming animal and forest is a lot of trees that are close together.
bushes or small trees growing close together dick
Plant heaps of trees, so that the roots hold the soil together
To hold the soil together. Many Thanks :o)
if the tree feels like attracting them, the yes.
Because the trees are close together and there are many other plants in between the trees, which block out a lot of light from reaching the ground.
