Euonymus Japonica problem

Please can anyone help. We planted some Euonymus Japonica hedging a month ago and have recently noticed that the leaves are curling up and dying. Pictures attached. Does anyone know what the problem is and how to solve it ? Many thanks

    Your first 3 photos and the last photo looks like a Portuguese Laurel. They look like the beginnings of Powdery Mildew which is normally due to lack of water, so make sure your newly planted shrubs are receiving sufficient watering right into the base of the plant. Be generous. Judging by the size of plant, you will need around a bucket every 3-4 days, but if warmer, every other day. Don't water overhead, especially when the sun is out. You may damage the leaves.

    The fourth photo is a Bay tree, Laurus Nobilis. Yellow leaves are indicating the leaves are about to drop. This is normal for most evergreen shrubs. Leaves will die and new ones replaced. However, if you are seeing excessive drop, it could be a number reasons. Inconsistent watering, cold and extreme weather damage. If it's a container plant, make sure you have good drainage for them. Place them against a southerly wall for back protection. They tend to be more vulnerable to the cold in pots.
  • Thank you. First 3 photos- We were told that this was a euonymous Japonica. We have  been watering them but will try more. Do you know what insecticides are best for these plants ? Thanks

    Looking at all your plants there is nothing serious going on. It's about keeping your plants happy, and these issues will go eventually. You can prune off the damaged leaves if you want. When your plants are stressed, especially water stress, Powdery Mildew and pests may nibble parts of the leaves. This may look slightly unsightly, but not serious and it is really rare to see shrubs without the odd scar or damage. Not anything damaging in the long-term from what I can see.

    Just keep on top of the watering and ensure the plants are not planted not too close to a boundary wall. Always allow at least 2 feet from the edge so they can have space to grow. Mulching a thick layer of compost or bark chip can also help to conserve water and keep the roots warm in winter and cool in summer.

    I'd agree with everything @Borderline has said. There's nothing major there. All plants have yellow leaves at times, and evergreens shed them throughout the year and produce new ones. I would strongly doubt they need any insecticide.
    They also look like quite large specimens, so it's even  more important to be watering well. I'm assuming the ground was properly prepped before planting too. If not, that can cause problems later. As much time and money should be spent on the planting hole as on the plant. It pays off in the long run   :)

    How is the bay tree planted? It looks like it's in a pot. If so, that requires more care - soil refreshed each year and enough water during dry spells - possibly every day. 
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...
