Citrus Trees in containers HELP
Ok, so for two years I've struggled to get my citrus trees to thrive. THey're holding on by a thread. I get them looking good, then they crash. I keep them under lights indoors during the winter and in a protected location that gets plenty of sun and natural water in the summer. I fight yellowing leaves, leaf drop, and mishapen fruit. I bought them as certified disease/insect free. I do treat with an organic insecticidal soap and neem regularly for spider mites and scale. I've tried several different soil blends; different pots. Different fertilizer/amending mixes ... all to my frustration. I love citrus - I have a lime, a meyer lemon, a navel orange, and a ponderosa lemon. the lime is the healthiest, but yet as flowered/fruited - so is the youngest of the lot. the Meyer Lemon is in a DWC hydroponic set up and seems to do well, but still struggles despite regular nutrient/water changes... The other two just seem to hang by a thread - and I am tired of them not thriving. I am considering Al's gritty mix and repotting them into cloth/nursery bags next time I move them to give them a little more aeration/drainage. Help! I'm open to suggestions, ideas, criticisms ... I must be able to move them indoors in the winter so pot size is somewhat limited. All the trees are on dwarfing rootstock. I know citrus tend to have more shallow root systems than other trees so wide pots are preferred to deep. I await the knowledge and awesomeness of this group to help me get these babies happy!! So thankful for everyones input!! THANKS!
