    The best single thing you can do for a potted Acer is topto it on. That looks like a small pot for the size of the specimen and no amount of liquid feed will compensate for roots that get too warm in a small pot. 

    But aside from that once a month liquid seaweed or an ericaceous feed will do nicely. Frequently forget about it and they don't mind. No point in overfeeding a tree. Another option is a slow release fertiliser put in the soil at the start of spring and left alone for the season.

  • I did mix some Chicken pellets into the compost in April because I do that on my borders every spring anyway,so do you think that will suffice for the season? Also could you tell me  when I should repot into a bigger planter.Many thanks for your valuable advice.

    I'd be wary of using chicken  manure. My understanding is that it's slightly alkaline.
    Better to use a proprietary feed or seaweed. 
    They need repotting very two or three years, only moving them up a small amount at a time to prevent young, fragile roots drowning in too much moisture. Although Acers require, and prefer, plenty of moisture, they also need good drainage.

  • Ok,many thanks Fairygirl,I will take that onboard in future about the Chicken pellets,would it be wise to wait until it’s dormant again to repot it.

    But it's looking great so take your time and find a nice slightly larger pot. In a pot I'd avoid any organic fertiliser as it would perform better in the ground where you have the microorganisms to break them down properly. An inorganic granular fertiliser like Miracle Gro or Growmore works better in pots as they're heat and moisture activated so they're more effective in the confines of a pot. It took me a while to work out that basic fact...but we live and learn.

    We have two Acers, red and a green one, both look like they have burnt leaves yet they're kept in the shade, can anyone tell me do they prefer shade or sun? 
    Many thanks 
  • Thank you very much both for your valuable advice.

    Dappled shade is best for virtually all of them @Daffodil59, but the red ones need a little sun to make the best of the foliage. Late sun is always the most suitable to prevent that searing heat through the main part of the day.
    Wind/sun are the main reasons for leaf damage, but so is insufficient water - especially at certain times.
    If you think about the climate we have in the west of Scotland, and how well Acers grow here, that gives you a clue to the conditions they like best. It's very similar to their natural habitat.

    Thank you very much Fairygirl, I appreciate that, fortunately they always come back each year but I would like to give them the best to prolong their best growth.
