OHxF 87™ makes a tree slightly smaller than Bartlett on seedling root. It is considered a semi-dwarf tree. OHxF 87™ is one of the best producing rootstocks of the OHxF series and was selected for this reason. The OHxF selections are compatible with most pear varieties and are known for their tolerance to blight and decline. Research from Oregon shows OHxF 87™ is an excellent producer. OHxF 87 should be planted 6-8′ between trees within a row. It gives early vigor and is more precocious that OHxF 97. It is also best when paired with a vigorous variety such as Anjou. It is not good for interplanting with less vigorous trees due to competition for light. As a patented selection, OHxF 87™ is available only through selected outlets.
