When was the last time you re-potted, and what kind of potting mix do you use? By the way, containerized plants may very well need to be fertilized through the winter, especially in a location where the sun is plentiful. If those are the only elements in your fertilizer product, you may have some deficiencies going on. What name brand is it, so that we can look it up and find a label on line?

seems like it would be too close to the jasmine and large tree. it would be competing for nutrients. i would recommend a different location.

You are right to leave them in partial shade for a while......let them settle into their new home.....I suggest you leave them for 2 weeks and dont fertilize at all....Did you add any slow release? I try to make the mix as boring as possible when i transplant and add inorgaanics...I like perlite......to improve the drainage.....I also keep them on trays with pot feet to keep the air flow under the pot and stop them sitting in water...citrus hate that. I water them with seasol(seaweed)...water first and then a weak solution of seaweed and thats it....the seaweed stimulates root growth.........Let the pots dry out between waterings......put a stick down the mix and if it comes out wet...dont water.....dont feed until you see top growth....this might be a while..esp if the roots arre doing their thing......They look healthy......in the long run...look for roots growing out the bottom of pot...then repot.....dont disturb the roots much next time....just tease roots out a bit and pick a pot that 2 to 3 inches bigger all around than the rootball. Some slow release osmocote with a npk 5/1/3 would be good on top when growth is going on....no need to mix into soil.....little and often is better...not up against the trunk............fish emulsion and seaweed make goodd organic liquid feeds...always water plant first before watering with the feed.....move to full sun gradually....in winter move to shelter from excess rain/cold winds.If you were careful with the trees they shouldnt drop their leaves.......you will know after two weeks if you pissed them off!...remove any growth from below the graft(presume they are grafted trees)...are they dwarf? because if they are not....they will fill those pots pretty quick.Good luck

I can't say anything about the size of the pot without knowing how big the tree is. I don't think that filling the bottom with water bottles is a very good idea, though. It's bad for drainage. If you need it in a smaller container, you should really use a smaller container and not try to modify a big one. Citrus love nitrogen, and Holly Tone (actually all those "tones") doesn't have enough. I wouldn't modify anything now, though. It's pretty late in the year and getting to be time to give our plants a last dose of fertilizer before winter. If your tree looks healthy, I wouldn't fiddle with fertilizer changes until spring. Even a dwarfed citrus tree can get to be 20 feet tall if you don't prune it, so you should definitely prune it sooner or later. The easiest way to prune is just pinch off the green sprouts as they come out, but there's nothing wrong with using clippers. The best time to prune (if you need to use clippers) is also the spring. You should definitely plan to clear out any in-growing branches and any branches that cross each other, and if you have more than 2 branches growing from any one spot you should trim them down until there is only 1 or 2. You can prune for height at the same time, to keep the tree a manageable size. If I may ask, what zone are you in? And what kind of potting mix are you using?
