Falling/Leaning Trees

Lately I've gotten a bunch of plants from the nursery that were all tied to a post: Lemon Guava, Goji Berry, Tipuana tipu, Cassia leptophylla. I took off the supports and the Goji berry flopped over along with the lemon guava. The tipu and gold medallion, on the other hand, have a considerable lean. Why are these trees from the nursery so weak? I really don't want to tie them to the stake again, because I surmise that their dependency to the stakes is what caused such weak trunks in the first place.

How can I strengthen the trunks quickly and effectively?

It's common for young trees from nurseries to have lanky trunks that aren't very supportive. I always put a good strong post or two into the ground around my young trees and tie them off. There are some ties you can buy that are wire on either end with a strip of recycled rubber in the middle that won't damage the trees. I usually don't have to leave these supports more than a couple of years. The trees don't become dependent on them. Once they are out where they get good sun they will develop a stronger trunk. Nurseries raise trees in groups with the trees all sitting close together so that the trees are reaching for the sun and, thus, don't develop good strong trunks.

I might add too insipidtoast that those stakes will help the trees grow straight and not crooked and will help during strong winds until they are better established in their new home.

I agree, nothing wrong with properly staking trees for a bit. Especially if Santa Barbara gets anywhere near as windy as it does up here you'll need it. The key is don't stake them so tightly that they can't move--you want to let them be able to flex a bit in the wind, but not to the point where they'll fall over.

Hello and good day:
My question is the following" How can I find out how the roots of a Camphor tree grows? Does it goes deep down or does it spread to the sides horizontaly. The reason of my question: A camphore tree start growing very close to my inground swimming pool.
It is about 5 feet away from the pool. Should I remove it?
Thank you to whoever answers this question for me. Bye the way sorry for my Inglish I am from Holland.

Welcome to DG soccermantec, so nice to here from people from other countries, Holland was always one of my favorites to study in school. Here is a link that might help you make a decision on your Camphor tree, sounds like you need to move it soon. http://www.treeworld.info/f2/pruning-invasive-camphor-tree-roots-3817.html Sorry insipidtoast didn't mean to hyjack your post.

In addition to the above stated, you should stake a tree for no more than 1 year, and you should stake it in a way that allows for free movement; not rigid "tight" binding. For example, the tree should be able to move slighly either way in a wind, not stay stiff or unwavering. This freedom of movement allows the tree to develop a strong root system in attempts to keep itself erect. Should you stake it too tightly, the tree won't move at all, and it won't adapt to windy conditions, condemning it to be permanently staked.
