asian pear growth??
am looking for people with experience with asian pears on pyrus calleryana. I have lots of asian pears on pyrus calleryana But they never grow hardly any at all. I have some that are four years old and all they have ever done is leafed out each year. Never grown more than 2" the whole I have had them. One these varieties is yakumo and still living the others died of fireblight. I am trying figure out why my asians are not growing. I have euros on the same stock that are 8+ ft tall and very good looking with lots of lateral limbs. We get between 800-1100 utah chilling hours So I am not sure that chill is my problem but it could be part of it. Also I have a somewhat high water table at times of the year but again the euros still grow fine at these times of the year and the asians don't. What is causing my asians not to grow. they grow fine the first and sometimes the second year but then after that nothing.
