I have removed old pear tree and want to plant there plum tree. Is it possible to buy tree that is 4-5 years and big enough to give some shade to the area and fruit of course.
Since these are fast-growing you should just buy a normal garden center size and wait a few years for it to develop.
Thank you, bboy. I'll think about it
Even first year fruit trees can produce fruit although you are encouraged to remove any to hasten establishment. Also, the vast majority sold these days are dwarf and semi-dwarf trees.....not ideal for much shade production :-) You could also try Big Trees in Snohomish - they sometimes have more mature fruit trees as well as ornamentals. But you will pay for additional age and size.
Raintree Nursery in Morton sells large potted fruit trees. It's a drive from Seattle but it's a nice drive, and they have a lot of stuff. No delivery though - you'll have to be able to haul it yourself.
Plum trees do tend to grow very fast, as bboy says.
I have apple tree which is grafted with 4 varieties. It is dwarf fruiting and took 3 years after we brought it to actually fruit. But fruits in abundance now. size of the fruit is getting better and now it has started fruiting every year as compared to last years when it fruited only alternate years.
For bigger fruit thin each cluster.
