    I have 3 brugs, two of which are next to each other. These were purchased as plants from the garden centre a few weeks ago - Arborea and Suavolens. The Arborea has completely gone apart from the growing tip and the Suavolens is now being eaten. I spray them but can’t see any bugs on them. Any ideas what it’s is? Also, should I put the Arborea in the bin now?

      Its probably slugs or snails.
      First pic could be Red Spider mite, but not easy to say without a close look.
      They can both recover, but I'd tend to move them to a different position, even put them in a greenhouse for a couple of weeks if you have one.
      They really need to be bigger than that by now if they are going to flower this year.:frown::smile:

        The leaves on the Arborea seemed to be twisted and dried up and then they fall off. There’s no slime either so I don’t think it’s slugs or snails. Haven’t really had any problems with them this year.

        I have moved them to another location now.

        I have one Grand Marnier cutting that survived the winter, but even that is only around 10” high, but no signs of bugs on that one.

          Have you got a magnifying glass?
          It does look a bit like RSM on the first one, they dry the leaves out before they have chance to form.
          They are tiny, not red, more kind of yellowish at this time of the year.

            I will have a look in the morning. If I don’t have one I will see if I can get a better image of the Arborea on my phone camera rather than the iPad.

                OOh yes, looks like RSM to me.
                the webbing is probably just from an ordinary spider, but the lack of leaf growth looks to me like they are the problem.
                Pic 3 also looks like it, I'm guessing the white specks are the eggs.

                But would be good if you could actually ID a tiny yellowish insect moving around mostly on the underside of the leaves.
                I used to be able to see them with the naked eye, but these days I need a lens, I have one that magnifies X10 which I find very useful.

                  I will try to video close up. Not sure if that will help? Also, how would I upload a video - any ideas?

                  Will regular bug spray kill RSM?

                  Sorry for lots of questions :snorky:

                    Well, although most sprays say they do kill RSM, not found one that kills the eggs which tend to hatch out pretty fast, so you end up repeat spaying which tends to kill the plant anyway.

                    I use this stuff, not allowed as a plant spray, but brugs are ornamentals anyway, I find a light spraying, leave the plant in the shade for a few hours before moving to normal conditions.

                      @pete I checked front and back of the leaves and can’t find any signs of eggs or RSM? I have no idea what it can be :scratch: Just in case it is slugs or snails, I have put some pellets in the pots, so if it is them, I should know in the morning.

                        Thanks @Gail_68 . Whatever it is, the blighters have had a right meal out of my Brugs. I have sprayed them with bug spray and put pellets down in case it’s slugs or snails. If the leaves still get eaten, I haven’t the foggiest what it is :scratch:

                          I can’t see anything on them though. And how can you treat something you can’t see or know what is?
