I have a large coral honeysuckle that's about 6 years old. I live in eastern Pennsylvania. For the past 5 years it's been flourishing, but this year- all of the branches, except for a handful, are dead, and there are only a few leaves and blooms. This vine is in indirect morning sun and direct afternoon and evening sun and is trellised (wooden). It is also supported by two iron rebar bars. Are these causing it to get too much iron in the soil and killing it?
I have no idea of what's wrong with it.
Thank you for your time,
Yvonne
Answer Hello Yvonne,
When you say "Coral Honeysuckle" I am assuming you are speaking of the trumpet honeysuckle (Lonicera sempervirens) and so my answer will be reflective of this.
Trumpet honeysuckle are very susceptable to aphids and in severe cases the plants can be defoliated. Additionally, last summer was very dry, this would have had an adverse effect on the plant as well. The iron is not an issue. The amount of iron leached into the soil from the rebar is miniscule at best and would not have an effect on the plant.
Unfortunately I don't have one specific reason for the decline of your honeysuckle. I would suggest that you prune your honeysuckle back by about half and give it a handful of 5-10-10 or 5-10-5. Keep it well watered during periods of drought and by fall it should be looking good again.
