hawkeyesrule, more information is needed on this before someone can help. Do you have a name for this brugmansia or know the color of bloom? Brugmansia's leaves will sometime turn yellow if the move is dramatic or you have it in the wrong spot and it's unhappy.

I think she's just unhappy. Homesick. Try this: release yourself of the attachment and bring her back to her exact spot, at the school. Be patient, and keep your claim on her so that by the time she certainly recovers strongly, you will have a new home for her just like the old one. If possible, please try to reduce shock while transporting. Windburn (too much wind/leaves violently flap about) is a real phenomenon and shocks and kills many improperly transported plants. So pay attention to these factors, there will be a quiz later: Temp, Water, Humidity, Light Intensity, Light Duration, Soil when transplanting (mulch it). Got it? We can do this! n please reply here when Brug recovers! Love Socks

It's probably just the shock from moving, and then the difference in light levels. If it was in a greenhouse before, then it's just trying to adjust to the sun. If it's the older leaves turning yellow, but the newer growth is fine, then I wouldn't worry about it. It just take time to adjust to getting more direct light. When I put mine out for the summer, they transition like this too.

I have a potted brug (pale yellow-orange flowers) that has always had yellowish leaves. Every once in a while the leaves are a rich green, but then they go yellow. I'm thinking it's lacking a nutrient, or that our water is too acidic. Here in East Texas we have very acidic rainfall and drinking water.

I also now have several in the ground that are having the same problem. Should I try adding an alkaline amendment? I do fertilize every 7 to 10 days with Miracle Grow. Is that enough?

queencrimson, to solve your problem with alkaline you would need to add lime to sweeten up the soil.

hawkeyesrule, we got a nice brugs from FL that was so nice and green when it arrived, matter of fact you could feel the FL warmth when you opened the box. ; ) When we stuck her out in the quarantine are of the yard where new plants go she decided to show her true color, yellow!! It's been out there for a few weeks before it decided to change back.
One she hated to move, two we have had cooler weather than what she was used to and three dont' give up!! She gets sprayed and feed on a regular bases and hated the change.

So how is yours doing now?

I read in another thread here about yellowing leaves that several people recommended feeding with epsom salt. So I got some and will report back on whether it helps.

I have to say, it's never had trouble blooming, which it does most of the time. It's just that the leaves always look a little sickly, not a rich green.

I find that the afternoon sun is the strongest. Even in a greenhouse, the light would not be as intense as outdoors. As well, there will be a decided difference in the temperature and humidity level. I wouldn't worry about it, as it will drop those leaves, and grow new ones more suitable for the new environment ( probably smaller). Glad to hear that it is a good bloomer for you.

I fed with epsom salt and my leaves are now a deep rich green for the first time. I couldn't be happier!

Queencrimson, how much did you give them? Sprinkled around or dissolved in water?

Dissolved in water. Just 1 teaspoon in a gallon. It's in a large pot and doing beautifully.

I have several in the ground and only one is doing well, even though it's leaves are a bit pale. I'm going out right now to give them some, but will use a tablespoon per gallon, which is what most people recommend.

queencrimson, if you have a 'versicolor Brug ( and you may well have that when you say the bloom is yellow) don't expect the foliage to be a dark green, it just isn't in their genetic makeup to have dark green foliage I have found.
