Water Lily Holes
I think someone just mentioned this but I cant find it. Very frequently my
lily leaves develope little 1/8" brown brown circles, they multiply, the leaf yellows and dies. It is never on the newest leaves. Is this a calling for Potash or just part of the life cycle. Thanxx Bill Brister - Austin, Texas |

Water Lily Holes
ps They only seem to live about 5-6 weeks. Each time I pinch yellowing
leaves (in all phases) seems to be about 15-20%. Bill "Newbie Bill" wrote in message m... I think someone just mentioned this but I cant find it.

Is this a calling for Potash or just part of the life cycle. I find that once the summer gets going, the lillies go crazy and pruning dead leaves is a near daily thing. This year I potted my lily in stones, and it is not doing so well, so I have not had the maintenance. When the leaves do turn brown, small holes seem to be part of the norm, at least they were last year. Now, I must also disclaim that I had an aphid issue last year from some imported water lettuce, so they could have been part of the problem. My big problem this year is the dern frogs. They are all sitting on my lotus leaves, and their amorous behaviour is scratching and tearing the leaves. BV. |

Very frequently mylily leaves develope little 1/8" brown brown circles, they multiply, the leaf yellows and dies. Hi Bill, A worm causes these small holes I forget its name. They eat holes in the leaf and then wrap themselves in pieces of it and float to the next leaf and start to do their damage on that one. They do need to be controlled unless you like the look of all your leaves with holes. They also will burrow into the stem of the leaf and turn it yellow prematurely. They do make the plants unsightly and not as strong growers. So it's a good idea to deal with them. They can be eradicated with the use of a product called 'Thuricide' which is Bacillus thuringiensis Berliner. I buy it at Home Depot. This is a liquid, which you mix with water and spray on all the leaves in your pond. It does not hurt fish or frogs or plants. It only kills worms and caterpillars. So be careful when you use it to not get it on any butterfly plants, including water plants such as 'Water Hyssop' which is a host plant for the White Peacock butterfly. It will not hurt the plant but will kill any caterpillars of that butterfly that are using it as a host plant. (Yes, I'm a butterfly nut) Read the label and use only the proportions they say. Do not spray in the heat of the day. I only mix a half-gallon at a time, since you cannot keep it more than a few hours. I use 2 TBL per 1/2 gallon of water and spray in the evening and then again early the next morning, using up that entire amount. You may have to do this a few times if your infestation is high. After that you can keep them under control by doing it as soon as you start to see just a few holes in the leaves. It's not hard and keeps the plants looking much nicer and growing stronger.

Water Lily Holes
Hi Sue - It is so difficult to help diagnose over distance without being
about to see, but I hope you have pegged it. Saturday I waded into the pond and removed most of the leaves I could find with any of these symptoms - it was a bunch. Now I am almost certain it is some critter or condition, because by this morning there were already an alarming amount of leaves that seemed to be spotted and the little lite brown symetrical circles, to yellow to dark brown and submerging cycle seems to really have accelerated. It is now quite obvious that they are deteriorating much faster than new growth is coming - drats, drats, drats. I will try to get to HD or others today and try your suggestion quickly. One end was virtually covered till recently, but I fear it will be empty before long. Strangely one lily in slightly more shallow water seems to be less affected, though affected. Maybe the pack just hasnt made its way that far. I have been fertilizing about once a month, but havent located Potash yet - in the now unlikely case it is just a nutritional matter. Nitrates are about 10 and ph is about 7.8. Thanxx for your input and keep your fingers crossed for me. Bill Brister - Austin, Texas I"Sue Walsh" wrote in message om...

Water Lily Holes
Hi Sue, Ingrid and all - I have been having a problem find the 'cure' so
before I continued my search and possibly treat incorrectly thought I'd make one last check on symptoms. I dont yet have the resources to post a pic, but the one picture I did see about the moth showed leaves very similar but with approx. 1/4 holes. Mine have sometimes 50 little light brown very symetrical marks. To my eye it is not until they turn dark brown sometimes merge and start to decay that a very small hole about the size of a hyperdermic can be easily seen. Aside from never seeing any larvae alll the other description fits, including having seen some rather large moths nearby, though never close enough to see their markings. Do these symptoms sound like what you have observed or heard of? Thanxx again Bill Brister - Austin, Texas "Sue Walsh" wrote in message om... wrote in message ... china mark moth Yes that's it, thanks. Bill, You can pick up one of the little pieces and if it has leaf on both top and bottom, pry it apart and you will see the worms or caterpillars inside. Sue |

Hi Bill
If its not the worms then it might be a nutrient deficiency, notably pottassium. -- **So long, and thanks for all the fish!** |
