    I have 2 of these

    But one of them has insect eggs of some sort on the leaves and the branches look white and powdery. Any ideas what it might be?

      Personally I wouldn't worry what it is, I'd just spray it.;):biggrin:
      Looks like some kind of aphid though.

        Is the white powdery stuff aphids as well or is there two different things going on?

          Not sure, maybe they overwintered in that waxy coating on the branches.

          On a different tack, I see you have some plain green shoots that need pruning out.:smile:

            The stuff on the stems could be some kind of scale insect perhaps

              I'll spray the leaves and stems. Thanks.

              Today was the first day we looked at the trees, I agree the green leaves need pruning out and the trees also need shaping.

                I think you might need a systemic insecticide on what ever that is on the stem.
                The white stuff is probably some kind of protection, so contact only stuff might not work.

                    No.:rasp::snorky: everytime I go to buy some it is different, they ban this, then something new comes out and then they ban it, I cant keep up anymore :old:

                    I'd just google systemic insecticide.

                    Or usually I go down the garden centre and spend the odd hour reading the labels:smile:
                    It keeps me off the streets,:biggrin: but take your glasses, the writing is getting smaller these days, along with the bottle sizes.:biggrin:

                      Could it be woolly aphids.? They like a lot of ornamentaland fruit trees.. If you take a small twig and scrape off the fluffy coating, underneath you will see the tiny bugs feeding on the sap of the tree. They are brownish and elongated. The fluffy material will start appear in small amounts now in spring and become larger as the year progresses - it is not present in winter when the bugs are inactive.

                      Woolly aphid overwinters on its host plants as nymphs that hide in cracks in the bark or in crevices around old feeding areas. During the winter months the aphids do not produce the waxy material that gives them the characteristic woolly coating in summer.

                      In spring, the aphids become active again, mainly around old pruning cuts or other places on the trunk or larger branches where the bark is thinner. They begin sucking sap from beneath the bark, and start secreting the fluffy ‘wool’.

                      Infestations reach a peak in mid- to late summer, when the aphids spread onto the younger shoots. Chemicals secreted into the plant as the aphids feed induce lumpy growths in the bark, especially on the younger shoots.

                      Sadly if it is it is a nightmare to shift the waxy-woolly protection But you can sort of stroke it away with methylated spirits or even shifted with a gloved hand, making the insects vulnerable to insecticides, or whole branches can be scrubbed with a brush dipped in soapy waterwith added Neem oil

                        They are right next to where I have moved single stem fruit trees as well. I better get them moved pronto. Thanks for the advice.

                          Kazza what ever the affect don't let it near your other plant if it's ok and I think this link will help you in a good way as it shows all Aphids to different plants mate.

                              It looks like I have Woolly Aphids on both trees, so I’ve now moved them well away from everything else.

                              With the soapy water, do I have to add Neem Oil or can I use it without? Can I also use washing up liquid and is there any specific amount I need to use?

                                Oh dear I did wonder if they might both have it, Blumming things.. I think you could start with washing up liquid and a scrubbing brush and see how you get on but if you can get some neem oil it would help a lot it is really good.. Wooly aphids are prone to attacking stressed or unhealthy trees.. Not saying yours are but I would make sure your trees do not dry out keep moist all the time, maybe a feed as well as that many aphids supping away there will be exhausting them.. Let us know how you get on.. :thumbsup:
