Amorph Blues Part 2

From: "Marge Talt" <mtalt at hort.net> on 2004.07.30 at 08:31:29(11875) All plants, including Amorphs, need to be hardened off gradually when taken from inside to outside - no matter whether it's to get them used to a change in temperature or not. You can't put them outside in the sun without having leaf scorch - which is what happened to your plants - because even if you had them under lights or in a sunny window inside, the light intensity out side is much higher - even in a shady spot. The leaves that the plant makes inside are simply not use to that kind of light intensity and can't handle it. Best to put them out in a shady spot and gradually move them into more light over a period of about a week. There's nothing you can do about the leaf damage at this point. As you have noticed, the scorched bits will die off. The rest of the leaf should remain. You can cut away the dead tissue if it gets on your nerves. +More Since part of the food making machine is damaged, I would expect you won't see substantial tuber growth. Shouldn't kill the plant, but it's a set back. Personally, I'd move the plants into dappled shade for a while.

From: "Wilbert Hetterscheid" <hetter at xs4all.nl> on 2004.07.30 at 11:44:19(11878) Suddenly putting an Amorph in the sun is a bad idea. They are not sun-loving plants to begin with, although some do accept a few hours when the leaves have developed in bright conditions. I don't think your bulbifer will suffer too much. It is a very strong species and even one of the few able to make a second leaf after disturbance. I guess your "hildebrandtii" is probably Am. taurostigma and that is a species from brighter locations on Madagascar, so that one might be "pre-adapted" to more light.

From: <r2ot at charter.net> on 2004.07.30 at 12:41:14(11879) Neil +More The same thing,it seems, happened to my A.bulbifer but it happened when I put it out in very early May when it was rainy almost every day and temperatures typically dropped into the forties at night. I thought it was a fungus that might have infested the leaf with all the wet weather

From: ken at spatulacity.com on 2004.07.30 at 13:02:43(11880) Neil, It just got sunburned. This is common when placing any plant outdoors in the sun after it's been indoors. Even we cacti growers take weeks to acclimate our plants to the outdoor sun, starting first in a partly sunny location and moving gradually into as much sun as the plant will like. This is a good lesson that a lot of plant-o-philes need to learn more than once. A sunny window is no match for direct sun outdoors. The intensity outdoors is *much* higher and plants get sunburn just like people. The plant should survive, but if the leaf is too damaged then you must hope for a new leaf to sprout. +More And just because I'm well acquainted with plant sunburn doesn't mean I always do it right, either. I sunburned almost all of my A. dunnii this spring! My own experience with the nice red edge on bulbifer, by the way, is that it appears with the leaf is new and then fades. Is that what others have seen? -Ken Mosher ----- Original Message ----- To: Sent: Thursday, July 29, 2004 1:11 PM Subject: [aroid-l] Amorph Blues Part 2 > Sigh, ok last week i decided to put my A.

From: "bamboochik" <bamboochik at earthlink.net> on 2004.07.30 at 15:42:15(11881) Strong light is not the same as full sun. It just means bright shade with no actual sun touching the leaves except maybe in the early morning. Many people have lost plants this way. I would take it back inside and just do a "wait and see" if it can recover next year... Don't over-water or feed the plant. I have found that a B-complex -10mg can often help a plant through a rough time...b.f.n...deb +More ----- Original Message ----- To: Sent: Thursday, July 29, 2004 10:11 AM Subject: [aroid-l] Amorph Blues Part 2 > Sigh, ok last week i decided to put my A.

From: Neil Gordon <neil at ng23.abelgratis.co.uk> on 2004.07.30 at 17:21:00(11883) Yup, pretty much as i expected. Thanks for your advices guys and gals.

From: "CHAZMG1 at citlink.net" <chazmg1 at citlink.net> on 2004.07.31 at 00:08:10(11888) I assume each species will vary somewhat, but how much sun is best for good growth? I have had my A. konjac out in partial sun the last 3 years. This year it is getting actually quite a bit of sun (3 or so hours more or less direct) without any sign of burn other than a very small portion of an edge or so. My plant is near blooming size. Good luck with the bulbifer. Chuck +More Quoting Neil Gordon : > Sigh, ok last week i decided to put my A.

To my dismay, I found you can also get leaf scorch through bright light- over one winter, I had some varigated Clivias in the basement. When it got warm, I brought them outside and put them into a small opaque plastic greenhouse. They got badly scorched, even thought they weren't in the direct sun! I agree with Marge, move the plant into dappled shade. Wait for the next leaf. At least Amorphs don't take several years to recover.... susan

From: chris bob <handspeakboy at yahoo.com> on 2004.07.31 at 22:47:59(11893) I am also very currious about mow much sun is required for these guys... It seems like I am hearing anywhere from deep shade to an entire day of direct sun.. I do understand that it will depend on the variety. I know that bulbifer is more sensative to sun than konjac is. What I would like to know is what is the optimal.. Mine are currently getting 2.5 to 3 hours of full direct sun now with no signs at all of scorching... is this enough for good tuber growth ?

From: Neil Gordon <neil at ng23.abelgratis.co.uk> on 2004.08.01 at 20:18:05(11903) Well, at least its not JUST me! I was at Kew gardens today, and their Amorphophallus section had an A. Bulbifer which was also quite badly singed, as were 4 or 5 other ones only not nearly as bad. It has been quite sunny here in the UK for the last few weeks! There are 4 (full grown?) A Titanums their at the moment, one of which is about do start resting, and the other 2 look like they might be about to do the same, and one thats budding a new leaf, about 1 meter high at the moment, they look fantastic all furled up! Neil +More Sigh, ok last week i decided to put my A. Bulbifer outside, Now, a few days later (as expected) the bleached bits are dying off and my plants looking a little worse for wear. I guess about 30 - 40% of the leaf is still green and unafected.

From: Al Wootten <awootten at nrao.edu> on 2004.08.02 at 13:42:01(11908) Neil As usual I was late getting my plants out from winter storage; A. bulbifer already had 4" growth on it. Although I put it in a shady spot, someone tidying up the garden moved it into direct sun about early June. The growth shriveled and fell off. Now there is a strong growth again, which elongated from an adjacent spot on the corm. Clear skies, Al Quoting Neil Gordon : Sigh, ok last week i decided to put my A. Bulbifer outside, as we were +More having mice weather, and they produce nice pink edges to the leaf in strong(er) light, or so ive read, unfortunately i want out and didnt return for 2 days, when i came back, the leaf looked like it had been sun bleached, as its been very sunny here in the UK. Now, a few days later (as expected) the bleached bits are dying off and my plants looking a little worse for wear. I guess about 30 - 40% of the leaf is still green and unafected. Or perhaps it could be due to lower temperatures in the evening? Can anyone tell me how badly this will affect the plant? I guess it wont put up a new leaf if this one dies and wont increase the tuber size this year because of it. Hopefully i havnt done anything terminal to it. I had also put out the 2 A. Hildebrandtii I also have out next to it, and they are hardly affected at all, with only slight bleaching around the margins. I only realy discovered these plants about a year ago, so I guess im still a bit green in respect to growing them. Live and learn i suppose. Neil

From: "Marge Talt" <mtalt at hort.net> on 2004.08.02 at 16:50:42(11910) I think this must depend a lot on just where you are....sun being hotter the farther south you go (in the northern hemisphere) After I read one post about them needing shade, I got a bit nervous as mine are in what passes for sun here - nothing overhead and direct sun for about 2 or 3 hours a day and seem quite happy. The ones that I had at the edge of the covered walk, only getting some morning rays, were leaning toward the light, so I moved them to the "sun" position and they are doing fine - no scorch. I do think making sure they have plenty of water is important if they are getting sun - I am speaking of plants in pots - drying out will also scorch leaf edges.
