Spots, yellow leaves and dropping leaves on Brugmansia
Comments (17)Monkeyfoot- Thanks for uploading a photo. Despite the yellowing leaves, it look great! Like kayjones says, the leaves will grow back!:) Dan- wow- such a long post!:) Yes, I finally opened my web store, because I am feeling a little better. I am still in pain but the meds help me get around a bit more. I'm also on vacation so I thought processing orders would be a lot less stressful during this time. :) Mango Crush is such a vigorous fast grower and bloomer. Mine hasn't started blooming yet, but it won't be long! Glad yours is doing well. I love Morelia! Which angels belong to the Aurea group? I always have a hard time remembering. What qualifies an angel to belong to that group? I would be so honored to trade for some of your new babies to trial for you. I haven't done any hybridizing yet, nothing is really blooming for me. But they are budding up! Yes you gave me Rudy- and I just planted it last week in my front garden. I just LOVE Peaches & Creams' fragrance- you say it's better than that? Wow, I can't wait for it to bloom! Do you know who the pollen donor is? Very interesting! Thanks again for the tip for using molasses, I forgot about it. I will try it! My brugs are holding up well so far. The hottest it's been was 106*. I planted most in ground last year. Those in ground have a deep layer of composted horse manure over them, and I haven't had to hand water them yet! Thank God, I couldn't water them in my condition anyway! We are behind in our rain for the month so far. Get your list together soon, I'm selling the best angels fast! I have only a few special angels that are not listed on my site. Have to get some Murphy's to combat a few mites that I have. Looking forward to your email and photos when you can!...See MoreYellow Spotting on leaves - pics
Comments (2)I think its fungal too, however there is no white stuff on the bottom of the leaf. Unfortunately, its spreading. RIGHT when the first two female flowers have appeared. I've been spraying with Ortho Disease Control with little effectiveness....See MoreNew lemon tree losing the few leaves it came with – too many blossoms?
Comments (11)Hi Mike, thanks for that encouragement. I wasn't expecting to be able to produce fruit from this tree during the winter months. My first goal would just be to get a single lemon, maybe next summer, maybe the summer after that. I'm patient. The blossoms are wonderful and even just having them bloom is enough to make me happy at this point. I just want to make sure the plant is happy as well. I don't believe it has been warm enough outdoors yet to put this outside. I live in the Canadian maritimes and it's often windy and cool up here. It will be getting quite warm soon but it's only April still. Soon as it's at least room temperature outside, perhaps then is a good time to consider bringing it outside during the day? I have a cold frame I built onto the southwest face of my house where I'm growing my vegetable starts (tomato, pepper, eggplant, etc.). I just stuck it in there today and so far so good. It's about 70% humidity in there. But it still gets down to the single digits (Celsius) at night even though I cover the frame with a couple blankets. Hoping that isn't too cool for the citrus; I might bring it inside at night for the time being. It receives a minimum of 8 hours of sun. I still need to find a good liquid fertilizer. Do I have vinegar... well, sure, I've got white and apple cider in my kitchen. Is that useful for citrus trees? I'm not sure what kind of soil it came with but I can see perlite and the odd wood shaving... It looks fairly coarse. I'm not sure why it took so long to dry out the first time but I'll keep an eye on it....See MoreLemon tree losing green leaves
Comments (137)Almost any container grower who's been around the fora for a while and is trying to improve their game understands very clearly that over-watering causes the hypoxia (lack of oxygen) that eventually causes root issues. If we wanted to parse words and start looking at plants at the cellular or molecular level, we could find a number of causes subsequent to hypoxia that could be labeled as causal, such that they would displace lack of oxygen as the cause of root death. If all free oxygen could suddenly be removed from the soil, the roots would still have access to the oxygen within root tissues and the oxygen dissolved in water. Kozlowski and Pallardy in "Growth Control in Woody Plants" list Citrus as moderately resistant to inundation (flooding). This means that roots don't die within minutes of the oxygen supply being cut off is clear evidence that root death is a process, so the actual cause of death when free oxygen is removed would not be the absence of free oxygen. Lack of oxygen causes cellular dysfunction, which leads to other factors at the cellular level that cause loss of viability. You can look at what I said in 2 ways, you can say, "Hmm - he has a point"; or, you can say he's full of it and grasping for straws, basing his argument on a technicality. Which way you look at it doesn't matter to me. The reason is, if you think I'm full of it for what I said, you need to consider the fact that Silica's position is exactly the same. I wouldn't be doing anything she hasn't done. She named a secondary effect and made it the primary cause. Would it not make much more sense to either really enlighten us and explain what happens at the cellular level as roots slowly die, also siting tertiary, quaternary ..... causes until you arrive at the site of cellular death; or, would it make more sense to stick with the primary cause of hypoxia, which is resultant of over-watering. Having too much air in the soil isn't the cause of under-watering, but you sure can end up with too little air in the soil by over-watering. Assuming you're using a medium appropriate for conventional container culture, can anyone name a cause, the effect of which would be too little air in the soil, other than over-watering? What has occurred is, one person decided to rephrase a concept that is a foundational underpinning of growing well in containers, that is known by millions and millions of growers and clearly understood, and rephrased it in such a way that it's contentious. Intentionally confusing cause and effect as support for any argument is a pretty clear indication of the tenuous nature of the claim. Al...See MoreStefan Hinck
