Re: the symptom of overfertilized Amorphophallus?

Hi Julius,
  Do  not  use fresh horse manure. It needs to be dried, or it will burn. Most barnyard manures are hot if it's fresh.  It's ok if it gets wet after it's 'cured', in fact it makes a great manure tea. 
                                            Take care,

Dear All,

Rabbit droppings sound good!  
As a boy, my Dad and I would walk a large cow pasture and collect OLD cow-pies where we could see the grass growing up through the cake from below, or the seeds of Samman tree pods ("cow tamarinds") germinating in the pie, this meant that it was safe to crumble these older manure cakes around the roots of his prized Anthuriums.
I`m also interested in learning if fresh horse manure is also a ''safe'' or ''not hot'' fertilizer.  Back in 1959 I recall seeing the old folks in the U.K. running out into horse parades passing by in the streets of large towns, their coal scuttles and broom in hand, to collect the just-fallen horse droppings to put fresh on their flowering shrubs.  I was told that this was safe?

Hi Andras & everyone,
  I have learned that rabbit poo is a great fertilizer that isn't considered 'hot' like most manure fertilizers/soil conditioners.  I have a couple of rabbits and tried some 'fresh' rabbit poo on a few tomatoe plants.  Some were already doing well and some were not.  Now they're all doing great.  I looked this up to send out to everyone who's interested in the organic fertilizer concept.  The hay that falls under the cages (and when I change out the bedding) is great, too.  Mulch and fertilizer all in one!   I've since used it on everything from veggies to Philodendrons and so on.  Hope this helps.  Most manures MUST be comoposted well until very dry, but are still good.
                                          Great growing to all,
"Are rabbit pellets a good soil conditioner?
Answer: Yes, rabbit manure is an excellent soil conditioner. Dr. George Dickerson, Extension Horticulture Specialist, states that rabbit manure is "high quality" soil conditioner. Since such manure is accumulated most often in the case of pet rabbits, there is very little likelihood of weed seeds in rabbit manure since the rabbits are often fed prepared rabbit food which does not contain viable weed seeds. He reminds us that there may be some weed seed in the rabbit bedding material, but that should not be a major concern.
Rabbit manure is also less likely to burn plants than some other manures, so it can be added directly to the garden. However, as with most manures, it can be composted with plant material waste before being added to the soil. Manure contains nitrogen which helps with the composting of plant wastes.
Dr. Dickerson also recommends starting a vermicompost under the rabbit cages. Get some "compost worms" often available at fish bait stores as "red wigglers" and release them into a pile or bin of bedding under the rabbit cage. Then you will have a source of good manure, worm castings, and a source of compost worms for other compost sites in your landscape. You can find more information on vermicomposting at the NMSU Cooperative Extension Service web site: "

Dear Andras,

I am NOT an expert, but when I used to grow aquatic aroids, they used to suffer "leaf burn'', and I was told that the man-made granular AND some liquid fertilizers which contain ''salts'' were the main cause of this problem.  I was given some liquid fertilizers with a low-salt content, and advised to use them in a weak mix more frequently, and to allow rain to 'flush'' the soil as often as possible, I also used OLD cow manure and WEAK mixes of fish emulsion fertilizer, this certainly improved the leaf burn situation.  Perhaps you need to reduce the amount of fertilizer you use?
I hope that this may work for you.

Good Growing,

Hi All,

Thanks you for the responses. Let's see the answers:

- Sun burning and "peeling" - what means a type of mechanical damage (As I am correct)
- Over fertilization.

Because all my plants are inside the flat and none of them are in front of the window, the sun burst isn't my problem. As I know there was no mechanical damage, too.
But I fertalized my plants a lot, so it seems to be the real problem.

Thank you again Agoston and Scott!

Hi Andras,

This necrosis and burning of the edges of the leaf tissue is
typically a symptom of over fertilization.
