<span class="link_user">@moQui</span>, 100% great Idea… i know of a grower in Thailand, all pots are White !!
Even pullingba white t-shirt over the Pot is effective
<span class="link_user">@1Right_Angle</span>, Yes realised this very late :-/ ... First thought i did some wetting misstake.
DUnno if white plasstic poits would be enough to prevent this... Probably go with some straw around the pot next year...
<span class="link_user">@1Right_Angle</span>, Yes, i was going crazy why i get top yellow leaves... U can see on the soil pic that there is a stripe of wunderfull white roots. This is were i got my sticks round the pot to save them from wind... Sprayed some fish emulsion in the days after i found this... Dunno if it helped... But yellowing stopped after that and sunscreen.
