I have seven Eleanor Tabor (pink) Indian Hawthorns that I planted a little
over a year ago. All the outer, lower foliage is gone leaving only the top
center with any leaves. A landscaper was recently at my neighbor's house
and I asked him about it. He said it is a disease/fungus (he didn't know
the name) which frequently afflicts these plants to the point where he has
quit planting them. I'm in Zone 7. Does anyone know what this is and/or
what the cure is? Thanks in advance for any assistance.
As a guess, I would suggest that the hawthorns may be infected with fire
blight. I thought about planting a hawthorn in my yard until I found that
fire blight was a big problem. I've lost mountain ash and apples trees to
fire blight, which made me leery about planting a hawthorn. Check out this
site or do a Google search by typing in "hawthorn fire blight":
Related, as in Rosaceae? OK, but that's a pretty big group, I
can't find any indication that they are placed anywhere near
Crataegus, so the relationship seems pretty distant.
And I've only seen leaf spot on Raphiolepis (or Rhaphiolepis).
Dirr mentions leaf spot, but NOT fire blight.
Jim Lewis - firstname.lastname@example.org - Tallahassee, FL - Where the
Indian "hawthorn" is just barely hardy.
If you checked the site I listed, Jim, it stated an Indian Hawthorn is
susceptible to fire blight, which was why I made the suggestion. I checked
before purchasing a hawthorn and found they were susceptible. I'm sure Pam
has a far better answer than mine as to cause of the problem.
It is the same fungus that results in leaf spot on photinia, Entosporium,
although 'Eleanor Tabor' is supposed to more resistant to this problem than
many other cultivars. Unfortunately, there is no "cure" for fungal
problems - once afflicted it is very dfficult to control the spread of this
disease. Indian hawthorns are of marginal hardiness in zone 7 - I'd be
inclined to replace them with something more suited to your climate and
without disease problems.
