Need help with my Portuguese Laurel trees
Looking for some help and advice with our Portuguese Laurel
trees, we have had them in for 3-4 years now, planted as established trees and
up until last year they were going fairly well. However last year was not great
for them and the same is starting to happen this year.
Some are better than others but now all have yellowing leaves to some extent, see pics. 6 trees in all (sorry about the mess, waste from lockdown projects...) generally 3, 4 and 5 from left to right seem to be the healthiest.
Pruned them top and front late last year to see if that would help, this year they have been fed and watered regularly, the soil is very free draining. Have planted other plants around the base of some and soil is certainly not wet or boggy so don’t think it can be over watering... Could it be they are still not getting enough water?? Generally have been watering once a week or so but in this heat giving them more when watering the rest of the garden... There is plenty of new growth which is encouraging but can’t explain the yellowing leaves. The idea was to use them as screening which they are doing but they just don’t seem very happy at the moment.
Any help, suggestions or questions would be welcome.
A good feed for them would also be helpful, have been using a premium organic seaweed fertiliser and applying by foliar spray but happy to change if it helps. Could it be a nutritional issue? Soil is quite chalky and does need improving, it is getting as I do add well rotted manure every autumn but could do more? All a bit confusing as I thought they should be fairly bullet proof.
Look forward to hearing from you.
