Just a few questions
Comments (5)Always plant as soon as possible after you get them in the cool of the evening. I usually cut 3 or 4 V sections about 4cm deep out of the rootball with a pruning saw before I plant anything which looks to have too tight a root ball - it encourages new roots and allows the native soil to fill the gap and the roots to move into the surrounding soil more easily. I dont know where you are in central q. but azaleas and choiysia are not easy plants to grow well unless all their needs are met. Azaleas are very shallow rooted so suffer in our very hot climate even if they are in a sheltered area. If your plants are stressed by drought or heat do not prune or fertilise, they are struggling to stay alive, making new growth will just deplete their energy even more, what they need is mulch and water. Nursery plants are grown in "soil" which is watered automatically and often more than once a day, this is seldom possible in the home garden and once the pot soil drys out it is quite often nearly impossible to re-wet. If you use a wetting agent (liquid) it will help the plant while it is trying to adjust to its new conditions in your garden. Good luck....See MoreGrevillea's flowers die before blooming
Comments (10)You're having a bad time, aren't you Penny? Have you been fertilising? If you have been, stop it at once! As Mallee points out in reply to your banksia question, fertiliser can be poisonous to some natives, expecially those in the Proteaceae family, which include banksias, grevilleas and waratahs. Some people fertilise those plants with a special native fertiliser, which, if sparingly used, can hurry up young plants a bit. However there's no real need to fertilise native plants at all. If you have fertilised your potted grevillea it may be possible to flush some of the excess phosphorus out of the soil by lifting the pot so the water can run out the bottom easily, and then watering generously. Mallee's other point about poor quality water is another good one. Have you been using water polluted with detergent? If you are in a position to use rainwater only on your Proteaceae it's a good idea. Can you use bore or townwater where you are? If you are restricted to greywater, you could try keeping a jug beside the sink where you put the detergent-free water (such as the rinse-water from the teapot). Trish...See MoreGrevillea Problems
Comments (2)could it be that black sooty mould? if so that is commonly caused by scale insect and/or mealy bugs, and they are commonly bought to the plant by ants. mealy bugs easy spot they are little whitish furry bugs around near the growing tip, scale look like hard little pimply lumps also around near the growing tip. if it is the above you need to control the ants first then make a white oil solution (homemade is easy) and spray the infected area with that after the heat of the sun. it has been very dry of late that is when ants become more prevelant, also with your callistemon problem because of the dry (low humidity) could it be spider mite? if so they are easy to control just introduce some mist watering around the foliage area to increase humidity keeping a bucket of water under each plant will also help the humidity. in both cases if the problem is too bad a prune up to remove all infected tip end wouldn't be out of the question, just be sure to destroy the prunings don't compost them or hold them on site. len Here is a link that might be useful: len's garden page...See MoreMoving a grevillea
Comments (5)Prune the shrub, and maybe the deeper roots. The bit that Grevilleas really hate is having the surface and near-surface roots disturbed. Your chances are better if you can get a good wide cut, and don't even disturb the mulch layer. Keep the surface good and moist for a while after the move. Don't fertilise at all at all!
