what is the correct Ph in citrus,as at the moment mine is 4.6

A suitable pH for growing citrus is betwen 6 - 7. The pH of your soil does sound a little acidic for citrus. When the pH is too low you will notice that your citrus may suffer with a maganesium deficiency. Magnesium is very mobile in plants and a shortage of this element will show up as the leaves becoming pale, beginning with inter-vein yellowing of the outer edges of the oldest leaves, so that a V shape remains in the centre of the leaf. This deficiency can be remedied by adding Dolomite Lime to the soil, which will supply calcium and magnesium and also raise the pH. Water in well after applying. Keep your citrus well fertilised in both spring and autumn by using a specifically formulated citrus food such as Yates Thrive Natural Citrus & Fruit Pelletised Plant Food. It's enriched with Dynamic Lifter and has added nitrogen, phosphorus and potassium to give your fruiting plants the right balance of nutrients for their growing needs.
