I would like a few trees in my garden, but it's a small garden so I want to know about small trees. Are there any that don't grow to big? Thank you.
I suggest you talk to a good nurseryman in your area. Different climates support different trees but yes, I am sure there are some that will accomodate your needs. I have created standards (shrubs trimmed to a single trunk) out of many shrubs that will grow tall enough to use in this way but much more info would need to be provided. Your local source or research on the internet by your zone, soil type and location will be needed for success.
