How do tree's get to grow thick and woody whilst others dont? (like perennials)

Trees are perennials. Some trees are genetically ingrained to grow thick and bushy while the genetics of others is to grow tall and willowy. It works on the order of 'Humans' we don't all look alike or grow the same.
Hope this helps

It's not boring at all - I learnt it in my horticultural class and I shall look it up for you.
To suport the stem you need a broader stem and this is called secondary growth. You have to understand what phloem and xylem and cambium tissue is. Look it up.
Rings of phloem and xylem are produced on either side of the cambium tissue. The circumference of the stem also increases. A secondary ring of cambium is formed, on the inside of the epidermis and the cells divide to produce a layer of corky cells on the outside of the stem. This layer inceases with the growth of the tissue inside the stem. It is the xylem tissue which forms the wood. This happens every season and they form annual rings. The phloem is pushed against the cork layers so that it appeas to have two distinct layers, the wood in the centre and the bark on the outside.
Does that make sense? It is actually fascinating stuff, believe it or not. Basically the bigger the tree, the sturdier the stem will have to be to support it. basically the same stem, just older and harder.

Apart from genetics there are so many factors that influence how a tree grows & its height & shape etc.Is the tree out in the open,is in the confines of a garden,if so it is likely to have been pruned to shape & height,pruned trees do branch out & spread side ways,ithe soil in which a tree grows,the sunshine in gets all matter ,in a garden it is likely to get watered when it needs water,perhaps also it's nutrition is taken care of,so all in all I think it would fare better than a tree that fends for itself.

Trees are like people, some of them are thick and woody & chippy, others, bright and chirrpy. Is it nature or nurture, or both? Well, one could go on debating.

Use miracle grow water on their branches.
Keep insects away from trees, try washin trees down before spring, use a tablespoon of listerine per gallon water to keep pests away.

that is genetically determined. Why do we not become an ape or elephant?
