| I have read that cedar trees close to apple trees can cause cedar apple rust,sense leylands are in i assume the cedar group can they harm the apple trees? |
| Leyland cypress is not on the list of alternate hosts for cedar apple rust. Cedar trees (Eastern red cedar or Juniperus virginiana and many cultivars of juniper) in themselves do not harm the apple trees, but they may serve as the alternate host for cedar-apple rust. While it may be partially effective to remove any "nearby" junipers, the actual distance is usually somewhat academic since the fungus can be brought in on the wind. It is generally better to use rust resistant apple varieties whenever possible, and to use an appropriate fungicide on the apples if necessary. An additional control measure would be to physically remove any galls that might appear on nearby junipers. They look for all the world like orange jelly fish and appear in the spring. Hope this clarifies things for you. |
