Hey Workshop members,
I’m hoping to get some advice on how and if I can save these Escallonia Iveyi plants in my garden.
They have been in there for around 3 years now and have been growing really well until about a year ago the one on the end started losing a lot of its leaves. It was right after a hot summer so I assumed at the time it was just heat stress and with a little extra water I did manage to bring it back a little but it has never full recovered. It has got to the point that it’s almost bare now and while it continues to produce new leaves, they keep shrivelling up or falling off. After some research I thought it may be leaf spot so I removed all the affected leaves, cleared out the old mulch and put fresh mulch down aswell as some compost around the roots but after about a week it has just continued dropping leaves and it appears that the plant directly next to it is starting to thin out a little now aswell.
I’ve attached some pics of the leaves, it’s got me really confused as most articles I’ve looked up leaf spot on Escallonias online but they all seem to have black/purple spots with white dots in the middle, but I haven’t yet found one leaf with the white dots. Some are just going yellow, others are turning black, and some have random spots so I really have no idea what I’m up against here.
I have 5 plants in the garden bed and they all receive the same amount of water, sunlight etc. The ones at the other end are doing great!
Any advice? Thanks in advance! 😊
