Dying rhododendron and other unhappy plants

  • No gravel. Behind the fence was a temporary swimming pool until very recently. Now that gives one to think. Next door have also just had to cut down a cherry tree which they told us yesterday was hugely diseased. No info as to what the disease was but apparently the stump is mushy in the middle. That was dropping leaves on the lawn and garden.

    Appreciate what you are all saying but I'm close to 100% sure it's not water that's the problem. We water whenever the soil feels dry. We use tap water on everything else and if desperate on the rhododendron but only if we run out of rain water as we're in a hard water area.
    Everything was properly watered and got a drenching when it was watered. The loss has been so catastrophic that I think it must be something else.
  • Also plants in other parts of the garden are absolutely fine despite receiving similar levels of watering and being more in the sun - the affected part is North facing.

    I'm not sure what you mean by a 'temporary swimming pool'. 

    I was going to ask what was on the other side of the fence as that can have a massive impact on what you have growing. 
    I doubt the tree has much to do with it, but it would probably be drawing up a lot of water if it was close by. Hedges, other trees etc would all have an impact.
    Unless there is some serious problem with the soil you have, it's difficult to offer any other suggestions or advice based on the info and photos you've already given.

    I live in west central Scotland - not where that photo is...
  • OK, thanks anyway. The tree was essentially dead so no longer drawing much water and the grass between the tree and these plants was unaffected.

    It was a temporary pool. Can be put up, filled and then drained and dismantled at the end of the season. A bit like a giant paddling pool but you have to treat the water with chemicals as you would an ordinary swimming pool. Wonder if the water leaked and essentially poisoned the bed.

    Then that might be the cause. I can't think of any other reason.

  • Our neighbours also had one of those silly pools installed... it's a worry what treatments they use in the water. Thankfully we haven't had any ill effects from it as yet. Worth having a word with them and maybe have a look at the chemicals used, to see if they may cause harm to plants.

    ..it cannot be definitive without investigating the soil, but I would suggest it's likely Honey Fungus that has killed your plant, likely come from the tree next door, and is killing neighbouring plants too.. nothing to do with watering.. 

    ...it kills plants overnight...   check for more information on the internet..
