Potted Citrus

Posted 579 days ago

Hello All
This is my first post!
I am growing a Meyer Lemon Tree and a Mandarin Tree in pots, the pots are 48cm wide made from Terracotta. Both trees flowered by all the fruit dropped. This has happened twice. They have both developed yellowing leaves and are not progressing well. They are in a sunny position, get a weekly water, they were planted in a citrus potting mix which I have added Cow poo and some dynamic lifter. I did originally have ground covers planted in the same pot but have since removed.
The Lemon tree has a black soot and worm like creature under the top layer of leaf.
Could someone offer some kind advice please.
Thankyou
Karen

I'd suggest the following few things. Check that the soil is wetting out evenly all the way down. If not, add a few drops of dishwashing liquid to a 9l watering can (after you fill it),apply that, then a good watering on top.Un-sealed terracotta can dry the soil out. Also, try Iron chelate on leaves and soil. Do you have a pH test-kit? Soil should be around the slightly acid mark. Also, a dose of Seasol always helps.Possibly the ground-covers have taken too much Nitrogen, so a high-N tonic might help. Any improvement will show in the newer leaves in about three or four days.If not, it might be best to replace the soil with the best quality you can get, water-in with seasol, and don't feed until the plant re-establishes.For controlling the black sooty mould and leaf-miner, I'd ask at a good nursery,since many treatments for these will also kill off the good guys.(bees, etc.)Hope all this helps a bit.Let's know how it goes.
