|How close can we plant Foster's Hollies if we are going to use them as a screen for our backyard? We will be purchasing plants that are 3' in width and 6ft high. Can we plant them at 5'apart?
|The typical mature spread of these hollies is in the ten to fifteen foot range, so to minimize pruning needs (and for their long range health) you might want to allow them a bit more room if you can. Keep in mind also that their natural height will exceed twenty feet, so for the nicest look the width should be in proportion to the height you plan to allow them to reach. On the other hand, they will tolerate the frequent trimming, if needed, to keep them smaller.
