how big is your yard.. how high is the deck .. and anything else you can add that might help .. like where are you. zone.. soil ... etc ...

try to find something that has a fast growth rate.. check out the link for intro to conifers...

but stay away from anything MARKETED AS FAST GROWING ... fast to grow.. fast to disease .. fast to death.. as compared to other trees/conifers ...

the fastest way to privacy.. NOW.. is to rig up some type of lattice/bamboo screening .. that can be raised and lowered on days you want some privacy ... until our greenery can grow to height ....

large transplants of conifers.. take a long time to get established.. and end up taking more time to grow to size.. rather than smaller stock ...

good luck

Here is a link that might be useful: conifer intro

I am in zone 6 and have a 6 foot fence that I would like to plant against. There is about 15 feet from the fence to the house.
