Question:
I am interested in starting Pine Tree seedlings and have
not been able to find much on it. After
discovering the NEWTON Site I've found a little on the subject. However, my
question is: If the mature tree has many limbs which begin at (let's say) 10
feet off the ground, should I expect the offspring to take the same
general structure?
Replies:
John,
You can use the parent's characteristics as a general
guide, but equally important are the young tree's
growing environment. If the species is not shade
tolerant, for example, you might find its lower
branches dropping earlier than its 'brother' growing
in sunlight. Other
characteristics like tree height and shape will also
be influenced by the environment. For example, trees
subject to strong wind tend to be mis-shapen; likewise,
those exposed to salty air near the coast can be
stunted.
For a given area, the tree's parents can be a partial
guide as to what to expect in the offspring.
Good luck!

Thanks for using NEWTON!
Any tree will display the same general growth pattern as its parent. Many
pines usually shed their lower limbs due to shading from above, as they get
larger, but depending on species might get fairly large before that happens.
