Rose Plant Deficiency?
Comments (10)I'd like to post an update. Friday evening I took it to the bath tub in order to flush the soil with a large amount of water, in order to try restoring balance, in case the problem was any nutrient buildup. This in advance of the suggested repotting, which will happen as soon as we get to the store and find a bigger pot for it. (In the past it's responded well to life indoors and through winter, but I see now that wintering it would be healthier for it). In the meantime, since having posted last, it's even started blooming again, something it does several times throughout the year, regardless of season. :) Now for the reason I'm posting; I'm incredibly, incredibly stupid. I left the office Friday evening having forgotten to take it back to its room, having left it there until the soil drained completely, since it took a long while to drain. Then we were gone from the office for most of the week and this morning I realize what I'd done. This means, unfortunately, that it wasn't exposed to any light at all. :( It's back in the sun now, or light I should say, since it's cloudy and rainy out, but the tips of a good amount of leaves had already sagged and discolored, brown and then a border of yellow between the brown and the usual green. I don't think the damage will have been more than it can recover from, since this plant has always been really hardy and vigorous, but I was wondering if there's anything I can do to help it recover, besides being given full light again. I feel like such a monster right now! :( Any input, even insults, are more than welcome. I've included a picture, too....See MoreRose nutrient deficiency? (7 pics)
Comments (8)First of all have a soil analysis done. I have no idea what the pictures of your leaves show. Could be caused by many things. My soil test showed 7#/acre of iron. I posted the results of my analysis here and one response was that my iron was low. Although the foliage on my roses showed no chlorosis I tried some, I forget the name of it, but chelated iron. The rose in question responded. So this Spring I have been adding Iron in the form of Iron oxide. Too early to tell if it will make any difference. Hopefully someone will recognize your leaves as a symptom of something. It is really tough since there are so many factors involved....See MoreNeed Help in identifying rose disease or deficiency
Comments (4)I should have mentioned environment condition also: At present my roses remains in sun from 11am-4pm and tempretaure is around 39-40 degrees celsius (ya i know temp remain quite high in my area during summer) My roses are not in pots and I try to water them thrice in a week or when ever the surface of the soil appears to be dry. I also spray water on the leaves as summers are there. I have applied only a small amount of granular fertilizer recently that contains (humic acid 39%,ascorbic acid 20%, Amino Acids 9%,Thiamine 2%,Alpha-tocopherol 1% ,basicaly a root stimulant)...See MoreMineral Deficiency Symptoms in Roses
Comments (80)Over-fertilization: wilting, leaves curl down, plus brown burns at tip. Decade ago when my toddler sprinkled too much NPK 10-10-10 granules on my tomatoes, we got fat tomato worms for the first time ever (excess nitrogen & phosphorus attract pests). We had 1/10 the amount of fruits, plus leaves look like below: Too acidic: TOP LEAVES CURL UP. Tiny & pale and thinner leaves, bronzy leaves. Fungus: blackspots & rust & mildew. See below my Mustead Wood when I put too much acidic pine bark and acidic gypsum: Too alkaline: Pale upper branches. Note iron deficiency in upper leaves, plus zinc deficiency in older leaves (blotchy yellow) of below pic. Too alkaline with upper leaves twisted like witches broom (boron def). Too alkaline, iron def: pale UPPER leaves with green veins. See below with both iron (pale leaves) and copper deficiency (brown & dry spots) Too alkaline, zinc def: Short plants with a reduction in internodes length and leaf size. Leaf edges may be distorted or puckered and yellowing between the leaf veins, see below: Too alkaline, copper def: crinkled leaves, young leaves are dark green but twisted or misshapen, often with brown, dry spots. See below: U. of Colorado best describes zinc deficiency: "Plants tend to be stunted due to a shortening of the internodes. Leaves show a general yellowing of the upper foliage with a browning or bronzing of the older or lower leaves. The leaves of zinc-deficient typically have a crinkled appearance. A general downward curl of the leaves also will occur and flowering will be poor." Potassium def: Less blooms, balling, thin & weak stems, and blackspots, plus lowest leaves have yellow edges, then progressing to brown edge. Below is potassium deficiency in Teasing Georgia since I put too much lime in the pot. Too much calcium induces potassium deficiency. I reversed it with high-potassium fertilizer, note below new growth is normal: Calcium def: less petals, stunt growth & tip die-back & wilting top shoot, see below wilted shoot on Abraham Darby in 92 F, the growth is too fast, but there's not enough calcium. SOLUBLE calcium is known to help plants to cope with heat. Note below: young leaves are distorted, with curled margins and tip or with brown spots. Calcium def. is caused by low pH, below happened after a day of heavy acidic rain, then high temp: Nitrogen def: small leaves & pale LOWEST leaves, see below progression of nitrogen def: Sulfur def: below entire plant is pale & stunt growth. gypsum has 21% sulfur for growth: Too alkaline will result in newest leaves being pale (iron deficiency with green veins, but pale background). Older leaves become blotchy pale (zinc def.). To correct too alkaline, sulfur at 30% or gypsum (calcium sulfate with 21% sulfur) gives fastest deep-green leaves. Also high nitrogen fertilizer like MG-soluble for plants NPK 24-8-16 will make leaves dark-green instantly (but higher in salt with potassium chloride or muriate of potash). MG-soluble for roses 18-24-16 also work in deep-green leaves since it's more acidic, plus less salt with sulfate of potash....See Morepaola_b
