Yellow leaves on alyssum seedings, brown spots on guara - help!
Comments (5)Yeah it looks like to much water at one point in time. Do not stress the yellow leaves will fall off but just try not to over water anymore. If you notice things going limp then you got a problem. Just let them dry out for a little while and keep an eye on them. Maybe even put them in a little more sun. If the container is extremely light and then your seedlings go limp add some water, but I would try to not water for at least 3 days and put them in some sun. I know that was probably confusing 2 different signs of limp could mean 2 different things. As for the gaura it looks like to much confined heat. Put you some more ventilation holes in your container. Don't worry about those few spots....See Morebrown spots on giant moso seedling's leaves
Comments (22)My "runt' looked like that pic with the lime green leaves....I eventually lost it. I think Mike is right on that it isn't an exact science....humidity, heat, water makeup all play a factor. Hopefully mine is strong enough to make it thru this winter. I'm going to have to watch it carefully. Mine is looking like half leaves are brown and green, since i moved mine home i have a new shoot and a couple of new leaves that are green. my soil i used was native and a promix about 50/50....moved into a three gal when i got it from Kudzu last spring/summer. He sent mine in a little peat pot. it was about 3"/4" inches.... I was under the impression that "yellowing" of leaves were signs of overwatering. not brown "leaf burn"...maybe i'm the exact opposite....I'm lefty you know...lol....could it be that i have no idea what i'm talking about???? Leaf curl is signs of not enough water....yes?.....yellowing of older leaves and leaf drop in spring is normal....browning of the tips could be lack of protection from wind or suffering from transpiration...or at least something like that.....Maybe i need to crack open the old books again....

Comments (9)Hi Guys- I live in North Berkeley and all the plants in one of my raised beds look exactly like Irene's. What stinks is that I had first planted two plants from Spiral Gardens Nursery, who grow their own starts, and those did great, even in all the rain we got. Then I planted three plants that I got from Forni-Brown Nursery in Calistoga, which I am almost certain they grow their own starts (they sell mostly to the local restaurants in Napa Valley), and those did great. Then two weeks after that I went to Berkeley Hort and bought more plants, including some sourced from Sweetwater Nursery. While at Berkeley Hort I came across a Mortgage Lifter from Sweetwater, noticed that it was spotted, and brought it to the attention of a sales guy at Berkeley Hort and asked him if there were problems. He very patiently explained the "cold damage" and I believed him. Normally I'm totally paranoid, but I have shopped at Berkeley Hort for five years and never had any problems with plants there, and I consider their staff to be top notch. I also have bought lots of stuff from Sweetwater without a problem in the past. So I thought I should get over my paranoia and went ahead and got some plants there, including that spotty Mortgage Lifter. Planted those, rains came, and a week later, EVERYTHING in that bed had spots on them. Obviously this is all just my observations, but the bottom line is, I should have gone with my instinct and just left that Mortgage Lifter alone. Now it's a waiting game. I finally got to the point of not stripping any more leaves, even if spotted. It's now an experiment. The new growth has been pretty normal, no spots. I've drenched with Serenade twice, but it's expensive, so I've been using a baking soda/oil/castile soap "natural fungicide)" concoction. I can't tell if it's helping or if it's the dry weather that has slowed the leaf spots. I imagine that if I get more fruit set, the plants will only stress and get worse, and who knows if anything will properly ripen. I'm just hoping to get even a small harvest. We'll see. Good luck to you guys and hoping for the best for everyone!...See MoreNeed help with Tomato - Brown Spots, Curled Leaves, Indoor Garden
Comments (5)Dan, I've used a few different mixes in containers and I like the sound of your sea soil. The problem with containers is that the system is really too small to set up a true organic soil system in them. People do all sorts of things and may technically get away with it, but I my abilities can't do a completely organic soil and get reliable production, since any "help" and you kid yourself that it is "almost organic". That said, I had some luck with a mixture of 1/3 compost (Black Kow Composted Organic), 1/3 peat & 1/3 perlite in summer but you must watch it doesn't get waterlogged. I know it sounds strange, but raw perlite is "organic". You could put some of those fancy rock dusts in there and dolomitic lime and give it a whirl. Problem is at some point your plants will need the nutrient boost of something like Miracle Gro, which is not organic, but not as bad as some make it out to be, either! There are some Fox Farms hydroponic/organic and Dutch Master hydro organic ones, but these things are really cost intensive and there is no way I could afford to even evaluate them. Tomato-Tone is organic and you can use some of it (the affordable option I would use) but a lot of experimentation is necessary to get it right in a bucket. Those are the tools I would use. There are others that are more expert than I am in this forum on organic methods in a container, but the problem is that ingredients and climates can vary enough that a lot of experimentation is necessary anyway and it is a bit much to ask of a container considering the nutrient demands of a big tomato plant. And a bigger contaner ( say, 25 gallons) can be costly to fill with organic nutrients only. There are other much more economic ways to go if you drop the requirement of deriving all nutrition from "organic" sources, for example pine mulch, etc, is cheap but offers no nutrition so it doesn't get you anywhere nutrient wise, though it might help you save on perlite. I can't answer whether your tap is appropriate for your plant, even knowing the pH is 7.5. That's because it will be the interaction among the tap, soil ingredients and amendments that determine the pH of the container. For example, if your soil starts on the acid side which it likely will it needs to be neutralized with some lime, but you can do what I do ... put less in and water with alkaline water for a while. Clearly that is not an optimal situation but to be honest my plants do fine despite all the issues with pH, and my tap is pH 7.7. But this is a fragil relationship and the only way to now for sure is to pH test your soil while you grow toget the hang of what's happening, if you are really enthusiastic. Just because it works for me, btw, doesn't mean it will work for everyone. We get lots of rain here and that frequently washes trhough soil mixesand I purposely open the tops wide to encourage that. No residue builds up from the tap or any of my not-organic supplements due to the rain. The common wisdom of hydroponics of a vegetative and a reproductive period fertilization schemes doesn't seem very pronounced to me when growing the tomato for the long haul. To be perfectly honest, I think all these mantras about vegetative stages and drastic changes during flowering stages are geared towards high value crops LOL. Really with tomato plants you want to keep the nitrogen at a baseline, low in all of my scenarios. You are not growing vines, they get quickly unmanageable for indeterminates and make few tomatoes, and most everyone here seems to agree that being pretty stingy with nitrogen is the way to go. That's the opposite of what you've done. When I grow my tomatoes, my seedlings have only 1/2 to 2/3 the nitrogen the producing plants do, so my nitrogen rate actually increases for me. At the end I back off though because the plants get less productive and unmanageable so there's a lot of give and take. Hope that helps a little, because nothing is as easy as it seems, so most people find something that works and get pretty stuck to it. Cheers PC...See Morebarrie2m_(6a, central PA)
