Bought/potted my first citrus (Splitzer: Washington Navel/Meyer Lemon) back in September. Planted in a 500mm Artesian yates self watering pot because I'm in a rental, and added a slow release fertilizer sprinkled around the top, also occasionally spray with a seaweed tonic. Noticed this morning on just one the branches/stems that it had some leaf miners which i have pruned that piece off. It is now situated in the middle of my yard away from the fence. Before i noticed the miners it was more so the other leaves that were worrying me. Not all but a few have been curling and going a yellow/brown almost burnt on the edges (which I've pulled off to hopefully encourage new growth) After doing much online research only to end up completely confused (to much or little sun, over or under watering or simply wind damage or something else entirely), as to what might be causing it i thought i would come here. I have been watering daily in the hotter weather and we have had gusty winds lately to (with the nsw bushfires) Please help a beginner! (I'm so paranoid about killing my tree)

Thank you for including the photo. It does look like the leaf has been scorched. We have experienced some extremely hot windy weather in the past few weeks and I am not surprised to hear that a lot of plants have been affected. Citrus are very hardy plants so with the right care, I am sure your citrus will recover and do well. Citrus like to grow in a warm, sunny spot in the garden protected from hot drying winds. The fact that you have your citrus growing in a self watering pot will ensure that there is always water available at the root system of the plant. Giving it regular applications of seaweed solution will also help the plant to survive during periods of stress. You can remove any of those leaves that have been affected and then encourage more to grow by applying a product called Yates Thrive Natural. This can be applied every 2 weeks to keep the plant strong and healthy. If you prefer to use a slow release fertiliser, we would suggest a product called Acticote+Instant Booster. Acticote can be applied now in spring and then again at the end of summer. It will slowly release the nutrients over that period of time. Leaf miner attack the new growth in summer/autumn. Protect the soft new foliage by applying PestOil during flush growth period every 5 - 14 days. Aphids are also a pest of citrus that can damage the new buds if left unchecked. Make regular checks on your citrus to ensure the soil in the pot is kept moist at all times. You might like to put some sugar cane mulch on top of the soil to stop the feeder roots from drying out. I am sure will all this TLC your citrus will thrive and reward you with lots of juicy fruit. Happy gardening.
