We have a 20-year-old Snowdrift that forms a huge dome on the top of a gleditsia tree, almost smothering it. It is in full flower at the moment. Is it of value to wildlife (moths? butterflies?) or should I take it down and replace it with a later flowering one? It seems a waste!

Hi, if it’s becoming a problem then take it down after it’s finished flower and replace it with a viticella type. I don’t know whether they are of any value to wildlife but what I can say is that it’s not on our ‘bees and butterflies’ section (so probably not)
If you get one of our mature Viticellas in before the end of April then it will still do pretty well this same season
Hope this helps please see link below
