    Namaste all, thank you in advance for help on this one: I inherited a lot of outdoor potted plants, most of which are doing ok, but many are looking burned around the edges. They all live on the roof deck in full sun all day here in Kathmandu Nepal, and here's what the sick ones look like:

    Overwatering? Underwatering? no idea, and I have no idea what's in these large pots, as they were not constructed under my care :)

    Thx!

    Hi @Jigs Gaton your first pic looks to me like a Cordyline Australia Torbay dazzler and it's being scorched :rolleyes:...i'd say half shade because your centre is showing new leaves that are getting burnt...i'd get a garden fork and loosen that soil as it looks dry to me.
    I haven't got a clue on your second one sorry:(
    Third looks like an Areca palm...you need to loosen the soil.

    If it's hot where you are why not buy Callistemon (Bottlebrush) plants (Australian plants) they come in different heights and they just adore the heat and bee's love them...I had 7 but lost them to last winters cold temps but i'd had them a few years and there's different genetic's in them.

    I think they'd suite you beside Salix :)

    Well,, since these are inherited plants I would re-pot with some good soil ! and keep them in part shade with enough water to keep the soil moist ! Not dripping but just moist ! Then see what happens ! Too dry and too much sun looks like the problem !
    It will not repair the current damage but the new growth should be better ! If it is a dry climate where you are ,, mist the leaves frequently ! Couple of times a week should be enough and spray water till the leaves are dripping !

    thx @Gail-Steman and @mart! Never seen those bottle brushes here, but they look nice. Is 0c too cold for them? It's going down that low tonite! But to Hardy Maple's point, I guess I'll bite the bullet and repot all of them, over time. Then if things go wrong, I'll know more why. Btw, I mist the heck out of everything during the dry season here... Sept to April I don't think we get a drop of rain.

    Jigs they're a beautiful plant I learnt how to cut them properly after flowering and kept them in nice ball shapes..they've done winters here great and with snow on them but last winter with it dropping to -5 then raising back then dropping again it hit them hard...they cope better with -2 at a steady level...not temps going really low but they originate from austrailia and they look like a toilet brush with gold tips and they do collect some bee's plus they can tolerate going with out water but you still need to add some ;)
