Hi, our citrus tree is looking unwell after a season full of fruit. We contacted an Arborist who advised to do a skeleton tree pruning and said it has a 5-10% chance of survival. Last photo is what the tree looks like now. I am not quite sure where to go from here to help with new growth. Are there any products I should be using for the tree? Fertilisers, food, dressing/covering the new cuts to prevent pests like the borer entering, do I need to shade the tree (as it is very hot where we are in NSW), do I need to put a fence around the tree to protect it from our male dog doing his business on it?
Some good advice would be much appreciated! Thank you
Hello @S1
Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your citrus tree.
Your citrus tree has been through a tough time, but with a bit of care and the right products, you can give it the best chance of recovery. Start by feeding the tree with a gentle, citrus-specific fertiliser like Richgro Black Marvel Citrus Food or Yates Thrive Natural Citrus & Fruit Plant Food, both of which provide essential nutrients to support new growth.
To help the tree recover during the hot weather, applying a seaweed tonic such as Seasol will reduce stress and improve the health of its roots and overall structure. Water deeply during dry periods to ensure the tree is well-hydrated but avoid overwatering, which could cause further stress.
Since the arborist recommended a skeleton prune, the exposed branches and cuts can make the tree vulnerable to pests and diseases. Use Steri-Prune 250g Pruning Spray Paint on the fresh pruning cuts to protect against pests like borers and fungal infections while allowing the tree to heal naturally. Keeping your male dog away from the tree is important too, as dog urine can harm citrus trees due to its high nitrogen and salts. A simple temporary fence or barrier around the tree would be a good idea to protect it.
Given the intense NSW heat, providing some shade to the tree during the hottest parts of the day will prevent sunburn on the exposed branches. You can use Jiffy Grow Tunnel Shade cloth or similar products from the store to create temporary shade while still allowing air circulation.
Finally, a layer of mulch, such as Sugar Cane Mulch or Lucerne Mulch, around the base of the tree will help retain moisture and regulate soil temperature. Keep the mulch a few centimetres away from the trunk to avoid rot. With this care routine, your citrus tree has a much better chance to recover and thrive again!
