Years ago, someone posted a "Brugmansia Tea" and I forget what all is in it, but just got a note from someone where I live that is having some problems with hers and thought it might help. I remember it had Tea Tree Oil in it. Anyone have the recipe?! Thanks if you can help!
Thanks Betty, They aren't my brugs, but someone else from here in Spokane. I used the tea before, and yes it is expensive, but my brugs did do beautifully - however I don't recall ever using ammonia in the recipe. This person told me the leaves off of her cuttings were turning yellow, and also that she was fertilizing and watering daily. I think I religiously used this tea once a week, and I think she is over fertilizing.
Did she say how old her cuttings were? Are they rooted? If rooted in how large a pot are they? She is definitely fertilizing too much and may be overwatering as well. Once or twice a week tops for fertilizer. How long has she been doing this? She may have messed up the pH in the soil. If the pH is way off her Brugs may not be able to utilize the nutrients. She may need to leach out all the unused salts from the soil if she is using fertilizer that is applied to the soil. If she is spraying the leaves with foliar fertilizer, too much of a good thing is bad and the leaves could be suffering leaf burn.
Foliar fertilizer shouldn't be the only fertilizer used on any plant. Most foliar fertilizers don't address the root's needs and one may end up with too much top growth and very few roots meaning that eventually the roots won't be able to provide what the top portion of the plant needs.
Did she add perlite to the potting mix for faster drainage? Why is she watering them every day? Unless it's been very hot and the finger test for moisture comes out dry, she is also over watering. Get her to search for information on growing Brugs.
