Sandy starts with ... Hi, my 3 year old dwarf valencia orange tree has been growing very slowly and putting out yellow leaves with brown dots on the underside. All the leaves are also pointed upwards and curl inwards. What is wrong with it and how can I fix it? Thanks in advance

Pauline:) says... I can see its mostly on the new growth, it could be a magnesium deficiency. First go to would be a solution of Epsom salts, one teaspoon to a couple of litres. But certainly make sure the pot is not waterlogged or too dry, making nutrient hard to access. Maybe the mix needs renewing. Always use premium mix. | About the Author Pauline:) KYOGLE 2474 NSW 2474 9th October 2020 3:49pm #UserID: 24406 Posts: 1 View All Pauline:)'s Edible Fruit Trees |

Sandy says... Hi Pauline, thanks so much for your suggestions. That's right, the yellowing leaves are on new growths only, I've looked at pictures of various deficiencies but just couldn't quite work out which one the tree is deficient in, as the leaf doesn't have a very obvious pattern. I will try give it some Epson salt and see if it'll improve. Just recently it has put out some new growths, but they are tiny/micro leaves pointing upright (see photos), could this be a sign of Zinc deficiency? According to the website below, the youngest leaves are small and trim, and often upright in Zinc deficiency. What fertiliser can I use to fix it? https://www.yara.com.au/crop-nutrition/citrus/nutrient-deficiencies-citrus/zinc-deficiency-on-orange-citrus/

David01 says... Hi Sandy, Most of the citrus plants grow in pot will get yellow leave in winter when compare with plants grow in ground and your case no exception. Thing will improve when the weather warm up. The one already yellow will stay yellow but new leave will be back to green. No needs to do anything Just be patient And don't forget to give the plant a kg or two of Rooster Booster or dynamic lifter to support the new growth.
