How do I treat my dwarf lime tree that's not flowering and has a leaf disease?
I would love to know what to feed it / treat it with and how best to get fruit from the plant! Also it's in a 50" pot, are dwarf fruit trees okay to live in a pot forever? Will it need an upgrade?
Sorry to hear your lime tree is not performing well for you. Dwarf citrus trees grow extremely well in pots as long as the pots have good drainage,are filled with a good quality potting mix and the pots have been placed in a protected sunny spot in your garden. The 50cm pot you presently have your lime tree growing in is sufficiently large enough for the tree to live in for quite a number of years. When the tree is about 3-4 years old, it would be a good idea to repot it in some fresh potting mix to give it a new lease of life. To keep your tree healthy,feed your tree with a fertiliser that has been especially formulated for citrus. Yates have such fertilisers. Yates Thrive Natural Citrus & Fruit Pelletised Plant Food. It's enriched with Dynamic Lifter and has added nitrogen, phosphorus and potassium to give your fruiting plants the right balance of nutrients for their growing needs. The leaf disease you have referred could be caused by an insect called Citrus Leaf Miner. It is a tiny moth that lays its eggs in the new growth of citrus trees causing the leaf to curl with silvery lines throughout the leaf. Whenever there is new growth, Yates Nature's Way Citrus & Ornamental Spray can be sprayed onto the new foliage when it is about 4cm long. this will deter this pest from laying her eggs on the leaf. Remove the damage leaves and dispose of them and be ready to spray the new growth at the appropriate time. Scale is another pest on citrus and this too can be controlled by spraying PestOil in late spring/autumn. Scale is a sap sucking insect and is usually found on the mid-rib of the leaves and along the young twigs. Monitor your tree for these pests. Keep your tree well watered, particularly during the summer months and apply the appropriate fertiliser during spring and again in autumn. I am sure your tree will reward you with lots of juicy limes.
