    I would like to know if it is best to cut weeds off with a serrated knife just below the surface , hoe or pull the weed out roots and all . Green Manure ?slash and drop.cut below the surface or dig up and turn in .Compost on the soil and then mulched or dug in ? I live in a very dry zone . rainfall 300 to 400 ml per yr and almost all in winter . and finally what to add to the soil in wicking beds to feed the microbes ?

    If my soil has plenty of worms, is this a sign that I don't need to add any fertiliser?

    What is best soil composition for wicking beds?

  • 1 year ago @Sam Powrie

    Hi, I'm a long-time composter growing in 90 year old fixed raised beds built on what is essentially a beach-sand base in a smallish back yard in coastal Adelaide. I've bulk composted for years using a tank ring & dozens of bags of horse manure, coffee grounds & lawn clippings annually. I generally mulch using shredded sugar cane leaves. My soils are still quite sandy but this approach has seen them become much more water-friendly & productive with plenty of soil life, worms etc. Tomatoes, eggplants & perpetual spinach seem to do fine but I'm still having significant problems growing other brassicas, leeks & spring onions, rhubarb, chillis etc - stunted growth, plants fading away after planting & citrus just not fruiting or 'going' anywhere. Are there any other strategies I could try specific to improving productivity & plant health on my sandy soils. Although I've been composting for years I must admit that I've only recently discovered & started to use amendments such as Seamungus, Powerfeed etc with my current garlic crop. So I have limited experience with 'fertilisers' per se. I do notice that other local gardeners with much more sun-exposed gardens seem to do much better (so maybe my shade trees are an issue).... Any advice much appreciated!

    I have quite a large garden (front and back). Having tested the soil im sitting around 8.5ph plus a lot of areas are hydrophobic (it wasn’t looked after by the previous owners). I have started to add minerals, dynamic lifter, compost, soil wetter and now sulphar to some areas, but can’t afford to pay for the large amounts I would need across all of my garden beds. Is there a better and cheaper way to solve the issue?
