So I posted a picture of my Jerre Schwartz a few weeks ago with some crispy leaves here and there but otherwise healthy. As suspected it is doing fine, has still been getting the odd crispy growing tips here and there though. The other day I went to my usual garden centre and they had a fair few Jerre Schwartz, and ALL of them had the exact same thing! Is this a common occurrence with this cultivar? They all seemed fine otherwise, just looks like frost damage - on mine initially it tied in with heavy frost we had but since then we haven't had any, and the ones at the garden centre are in a netted/shade tunnel.
This is not common for Jerre Schwartz or any other maple. Yes it could be the end of frost damage, but I doubt it. My thoughts are a lack of water and I would remove the crispy leaves leaving the petioles in place. Water regularly and waite a few weeks for the second flush. But you may end up losing that branch. I'm afraid it's just a waiting game.
Those 3 pictures are of 3 different plants at a garden centre, all showing the same symptoms as the one I've got at home. Seems too coincidental, especially as all the other cultivars at the garden centre are fine! My own one does seem to be showing fewer patches where this is happening now. I slip-potted it into a bigger pot as it was getting fairly congested but not yet root bound, maybe that helped.
That will help get the nutrients to the roots. But I would suggest a full repot and root trim early next Spring before bud break. Re garden centres, I'm afraid they don't look after them that well compared to nurseries. Watering is often hit and miss, plus they put them whete they can be seen rather than in the ideal position. I've seen many in blazing hot full sun at garden centres to get we punters to buy. Hopefully we maple forum members are wise to that ploy.
I tend to use this particular one because they look after their plants well. They're family run and have expanded a fair bit the last few years. They've also got their own nursery area which they grow on some stuff themselves. I've got an account with them now for my business and they can order in harder to find stuff. They actually put me in contact with the Acer nursery they buy from in mid Wales, so I've been over there a couple of times and got to know the guy there as well - also a small family run business. I've also got to know the guy who orders in and tends to the trees at the garden centre, he knows his stuff quite well and used to be really into bonsai. He has a few of his own plants at the centre in their stock tunnels which he plays about with on breaks etc. I know what you mean about putting stuff in view for sale, but this place has a dedicated shaded area for all their ferns, azaleas, rodies, maples etc etc. They do move a few maples closer to the entrance during spring summer colour change, but that area is also under the polytunnel material so diffused light. The odd very rare occasion I've had where a plant fails (2 maples, 1 Daphne out of literally hundreds of shrubs!) They're very happy to just credit my account so I can take a replacement. They're a bit out of the way from where I live but I ALWAYS go there because they've got a specialist for each area - Rose person, tree person, conifer person, indoor plant person etc etc
Sounds like a very good garden centre @Cattwooduk. I do agree, they are not all the same. So re your Jerre Schwartz, keep it shaded in the hotter days this Spring and don't expect too much this year. I have found over the years that bought maples that have been protected in polly tunnels and then brought home to our unprotected gardens, can suffer from a settling in period. Maples that are mass produced like Jerre Schwartz are often brought on quite vigorously to sell in the Spring and can suffer for this. A bit like a garden show exhibitors that sells off their plants that have been either held back or brought on for a show and sold on the last day and when you get them home the stress appears. So my point is, do not be too concerned for this season or year tbh. 2023 with the care and attention you will give your maple, you will see it thrive.
