I am almost positive my Bradford Pear has fireblight. It is 13 years old so trimming it is not an option. My question is this: Would the fireblight on this tree have any affect on my rose and elderberry and burning bushes? Every rose bush I have planted has been plagued with blackspot, my elderberry plants that I planted this spring are barely hanging on and not growing and my 2 year old burning bushes are growing at a snails pace. I have rocky heavy clay soil. The wind blows the dead leaves from the tree all over my yard and I wondered if is is hurting these other plants. What can I do? Also if the tree gets cut down, will the bacteria stay in the ground? Can anything ever be planted in it's place?

Fireblight (if that's what it is) affects things in the rose family, so your roses could potentially get it too, but the elderberry and burning bush are in different plant families so they'd be fine. Fireblight is not the same thing as blackspot though, so the pear having fireblight would have nothing to do with your roses getting black spot.

If it does indeed have fireblight, you should avoid planting another pear or anything else from the rose family in that spot if you get rid of the pear. Some examples of other trees/shrubs in that family are apple/crabapple, cherry, plum, peach, hawthorn, Photinia (there are more--those are just some common ones)

Of course, this is all assuming that you've correctly diagnosed your tree...I would suggest at a minimum posting some pictures here to get some other opinions, or even better call in an arborist, or take some samples of leaves/small branches to your local extension office to get their opinion. There are other diseases out there that can affect these trees too.
