It's about 11months old, repotted in February, in a 400mm pot, in premium potting mix, sitting on a spot in my patio that gets at least 6 hours of sun. I've fed it with Dynamic lifter for citrus, last done about 6 weeks ago, and supplemented it with Epsom salt and chelated iron because of some pale leaves with green veins about a few weeks ago. It is planted in a Yates self-watering pot and has grown at least thrice its size since I re-potted it, and I water it twice a week with long deep drinks. Sone roots near the plants base were fairly shallow in the pot, easily exposed when I water and I would need to cover up once I was done. It was doing fabulously until a few days ago, when the weather heated up again (I live in Perth). All leaves have gone pale and are dropping in a rate of knots. I've given it a top up of seasol and pruned it lightly, but I am not sure what to do to fix it. My other citrus (lemon and mandarin) are treated the same way, and they're both doing very well. Does anyone know what I could do to fix it? I've taken photos, please PM me if you want to see it. Thank you so much!

Re: Sublime Lime Tree Pale and Dropping Leaves - Help! 3Feb 08, 2013 1:44 pm Please don't use things like Urea on plants. Whilst the perception is that wonderful things happen, the reality is that only a very small percentage of the nutrient applied is taken up by the plant. It will encourage water hungry growth sand leave the plant highly pest prone. NPK and all other Heavy fast acting fertilisers will do similar. In the end its your money down the drain rather than in the plant. Never feed a sick plant. Always feed the soil a sick plant is in. Chemical fertilisers kill soils and there's no shortage of chemical fertilisers with your plants name on them just tempting peeps to use them. Premium potting mix is fine but not all are as good as others. I know of a few that dry very easily and yet have somehow got smart water mark approved logo's on them. Personally, I would have fed it with something different and treating the plant with epsomsalts etc is a pretty good waste of money. Short term fix without treating long term problems. I know there is no shortage of professionals that jump on the epsom salts and assorted supplement band wagon. When you replanted, make sure it wasn't planted any deeper than it was in the pot it was bought in. If soil goes up around the base of the stem, it rots the thin layer that transports all the goodies up and down the plant and it drops leaves, turns to crap and dies. I'd be repotting it. Use the existing potting mix but blend it 50:50 with Coir peat (or coco peat as it is also called). Add some Seasol over coming weeks in a weak solution and molasses also. Make sure it gets nothing more. It will reshoot. Maybe look at using a different tub. It's pretty common to see problems associated with self watering pots. The water stinks up and becomes a breeding place of mozzies and root disease. Not always but its pretty common. Also new plants will still need to be watered from above because until the roots get down to the bottom they rarely work. Water can only be lifted to a certain height before other things need to help it up higher. It won't go seeping through the soil structure like many perceive. Re: Sublime Lime Tree Pale and Dropping Leaves - Help! 4Feb 09, 2013 10:32 am I should have added to chapter 45 of my reponse to mix in some zeolite or perlite through the mix in you pot. So a 50:50 blend of a Premium potting mix and CoCo peat. Blend around 10ltrs to 25lts of perlite. It works really well for me. Gives a light free draining mix yet holds water longer at the ideal moisture level and controls nutrient leaching. Better water use, better nutrient retention. Please don't use those popular, well marketed, salty liquid fertilisers we remember from 1981 EcoSeaweed, Seasol, Powerfeed, Powerfeed for Veggies(you can use this on much more than veggies), CharlieCarp are all fine and are the better new age liquid products that should be seen in garden sheds if shopping at Garden Centres for your garden stuff is what you do.

I know of a couple of Smart Approved Watermark products that are not compliant if fitted. About as meaningful as putting your trust in a "green" plumber! 3in1 Supadiverta.

Re: Sublime Lime Tree Pale and Dropping Leaves - Help! 6Feb 09, 2013 11:25 pm I think sometimes money talks. Overall though its a good programme and most products are worth while. Hello. I just bought a few acres in Habana, Mackay, and my horses seem to love hanging around under this tree. I would like to name the paddock after this tree. Can… 0 9528 Fellow Perth dweller.
