large, maple leaf shaped begonia
Comments (3)Hi, sorry, I didn't think anyone would actually answer my message. . . . I've looked at numerous begonia pics. It's (I think) rhizo. It has very large lighter green leaves. Thick stems, but the leaves hung down from the hanging basket I saw it in. It has kind of 'hairy' appearance on the leaves and stem, too I think. I looked at crassucaulis photo- not it (wouldn't mind having it though) looked at big mac, earl-ee-bee, heiracleifolia, and the very last one I saw online might be it-- but, I cant remember the name of it! As I saw photos I'd scribble the name down on a scrap of paper- I cant find the latest scribble. Might have seen it on taylor begonia site. I will look again. It has a 'maple leaf' like leaf, very large, bigger than my hand, light green, kind of hairs on it. It is a plain color, no spots that I can remember, or perhaps the very ends had a bit of reddish on them, not a lot. I appreciate your time! Does this help?...See MorePaper-Thin Brown Spots on Laurentii
Comments (2)I also live in 9b about 40miles, inland. I really don't know what causes these problems, at first I thought that I got water on the leaves and they then got too cold. Some plants get them and others right next to them do not. In the winter if a section of a leaf gets too cold, it will show up months later getting brown like a paper bag. Not enough water during winter will also cause this and too much will rot the leaves. I water by hand each plant trying not to get water on the leaves Winter or Summer. I have small spots as well, I still don't know what causes the problem. Other people who break all the growing rules with Sansevieria don't have these problems, and the Sansevieria that I grow out side also don't seem to have these problems, yet I have seen this happen to 100 flats in a covered green house with no temp. control go down over Winter. I haven't figured it out yet, if you do please inform the group. It could be poor circulation or drafts that may cause this problem, I heat my green house, so it can't be that, unless I keep it too hot, but the plants closest to the heater don't have the problem. I don't have any diseases in the greenhouse, and so far have not seen anything chewing on them. Most all of mine have flowerd this past Winter season, now they are really growing. Please keep me informed I really would appreciate your input. Norma...See MoreBlack spots on begonia leaves - bacterial? Fungal?
Comments (27)I am thrilled to report that my red-leafed rex is doing fabulously well now! After several months of relatively slow growth, I moved it a lot closer to the window, and here's how it looks now. Maybe a month ago, I moved it back from the prime windowsill spot so other plants can have a turn in the brighter spot, but I think it would like to be closer again, it keeps turning the leaves to face the light, so I spun it a little for the sake of a better photo :D. I thought they were lower-light plants, but this one and the silver one really seem to like being right up in the south-facing windows. I am kind of shocked at how broadly it spreads out - those are my feet at the edge of the picture, it's a big plant!! Unfortunately, I nearly killed the silver one over the same time - I had a really hard time getting the watering right, so was alternating between drought and overwatering, but it is coming back now, so in a few more months, if I'm careful, it ought to have filled out nicely. I have not had any return of the black leaf spot problems, or leaf edges dying, since early last year....See MoreThinning bare spots in established St Augustine lawn. See photos
Comments (18)For those of you who are unfamiliar, Neil Sperry is a Texas based garden guru. He has a radio show and is syndicated in many of the big news papers in Texas. Neil Sperry is the bane of my existence. Whatever he says, I do the opposite. I followed him from about 1992 to 2002 and realized my grass looked worse every year. Then I switched to organic and learned a lot about lawn care on this and other forums. He, apparently gets all his information from sponsors selling products. I could make a living following him around to fix the mistakes he has people making. Sunlight - Neil says, St. Augustine needs 4 hours of sunlight daily just to survive, and 6 hours of hot, direct sunlight if you hope for it to grow vigorously. Again, my front lawn in SA had zero hours of sunlight per day for the duration of 25 years. It was under the canopy of several very large live oak trees. For 10 years it deteriorated, and for 15 years under organic fertilizer, it looked great. Here is a picture of my grass grown in the most dense shade in that yard. Looking straight down reveals all the flaws in the turf. What you can see is the grass was growing outward and not upright. When it is in full sun, it grows more upright driven that way by the sheer amount of grass. Here is the same yard from an angle. The house faced north and this is the front yard. There is a huge tree to the left of the walkway and two large trees in the bed to the right. This yard got no direct sunlight at all. You can see grass invading between the bricks and over the concrete. It is not doing poorly. Neil Sperry would say this is impossible. Here is a picture of my current house - back yard, south facing slope in full sun. The grass is dense. You can see the grass needed fertilizer, but besides that...in the foreground is weeds mowed at the mower's lowest setting. You can see the St Augustine runners expanding their territory into the weeds at a rate of about 15 feet per year. You can see the hose and a long handled yard tool sort of buried in the grass. The only reason you can see them is the grass is too dense for the hose and tool to sink farther down. You can tell the depth of the grass on my dog's legs. They are buried to the hock. Drought - Neil says, St. Augustine needs more water than most of our other lawngrasses (fescue excepted). If you let it get too dry, and especially if you do so repeatedly, St. Augustine will be weak, and it may even die away. This is about the worst thing you can say about St Augustine. The main reason is it is bordering on untrue. It "may" die away. St Augustine is not bermuda. Bermuda will come back from no water for a year. Here in Bandera I had a side yard where the St Aug was golden brown. It had been that way for months before I bought the house. I figured it was dead and neglected it for another year, which was a drought year. But when I watered it, the golden runners came to life. It was solid St Augustine. Had this grass been in full sun, it "may" have died away, but for whatever reasons, it came back after getting no irrigation from June to March. Here is a picture from my previous house in George West, TX. The grass is 32 inches high and had not been watered for many months. You can see the top of my dog's tail and her ears (different dog). When you mow St Augustine high, it needs less water. If you don't mow it at all, it needs no water to thrive. Please do not let the so called drought intolerance deter you from St Augustine. Fertilizer - Neil says, in part, ... Most clay soils have excessive amounts of phosphorus (middle number of the analysis), so soil tests usually suggest a high-quality, all-nitrogen fertilizer be added. What the hell? Who has clay in Texas??? Okay, now the OP describes his location as between San Antonio and Del Rio. As it turns out, there is a pocket of clay soil in D'Hanis, TX, along that route, so this might actually pertain, TO HIM, but almost noplace else. Clay soil is a red herring. Get the soil tested if you absolutely cannot grow anything. Otherwise, go with organic fertilizer and see the miracle unfold. Disease - Neil says, Gray leaf spot is a fungal disease that shows up in mid-summer into early fall. You’ll see diamond-shaped, gray-brown lesions on the midribs of the blades and occasionally on the runners themselves. This disease is most prevalent following applications of nitrogen. In fact, the additional symptoms of gray leaf spot are yellowed leaves that look like they need more nitrogen. I get gray leaf spot any time of year. My lawn woke up with it this year in early spring. Caused by too much nitrogen? I get it after months and months of no nitrogen at all. Like now, for instance. The lawns on his St Augustine Diagnostics page are all mowed way too short. Between that and his comments on drought scaring people into watering too much, it's no wonder people have problems with St Aug....See Morehc mcdole
