The latest on this is that I have lifted the slab next to the plant and removed all the sand, gravel and mortar. Replaced it with fresh soil and have given it a couple of good drinks with water/feed. No open flowers yet but 10 days with no flower bud drop is a definite improvement. Will update if anything else happens.
Well done. Hope you get some flowers open tomorrow or soon after.
Yeeha, great news, the buds are just starting to open. Many thanks for your great advise. Happy new year to you all.
Post a picture when they open please. Enjoy your success and have a good 2018.
Looking forward to seeing the photos
