The Trouble With Damping-Off
If you grow plants from germ in your home plate or a glasshouse , at some point over the old age you may encounter the disease known as “ dampen - off . ”
This strange , fungal disease is upsetting because one mean solar day your seedlings look fine and the next day , as the infection sets in , they can swell , discolor , bend over , rot , and die .
You wo n’t in reality see a fungus but instead acknowledge a radical of symptoms that indicate it is present .
While there is no curative for affected seedling , there are things you’re able to do in the future to make damping - off less likely to occur .

What Is Damping-Off?
“ Damping - off ” is an umbrella term for diseases ( or the symptoms of diseases ) get by fungi and other pathogens in the grunge . It can also pass off in seeds and water .
While it is unremarkably afungal disease(or several fungal disease ) , some of the most common forms of damping - off are actually cause by differentmicroorganismscalledoomycetes .
Oomycetes , also known as “ water molds , ” are not fungi but share some vulgar characteristics with fungus kingdom including reproducing by spore .
Together , kingdom Fungi and oomycetes are the primary causa of damping - off , sometimes form together to cause more scathe than they could on their own .
Some common ones areFusarium(fungi ) andPythium(oomycetes ) , each with hundreds of different species .
Any time a industrial plant disease involves spore , as withhollyhock rust , we know it ’s going to be a far-flung , impossible - to - turn back problem .
There are various ocular symptoms that may come in seedlings :
You ’ll hear gardeners employ word like ‘ mushy ’ and ‘ sickly ’ and ‘ wilting ’ as well . Symptoms may alter but , overall , as the grower , you know something is wrong .
Damping - off is often associated with green algae growing on the Earth’s surface ofpotting mixture . This is because both break - off and alga favor dampen growing condition but you may have one without the other .
How Damping-Off Affects Plants
Damping - off can affect seeds and seedlings at any stage — sometimes without us ever knowing it .

How to Prevent Damping-Off
Before we jump into possible preventative activity , the sad true statement is mute - off is a persistent trouble for grower around the world .
Spores are everywhere .
First identified 100 of years ago , it remain a multi - million - dollar sign problem in agriculture today .
As one recent research paper put it :
“ Despite a foresightful history and a number of research kit and caboodle direct on muffle - off , it still act one of the most difficult job to be managed both in the nursery and field . There is no rural area or geographic area without damping - off job , on a turn of economically authoritative crops . ”
It ’s fair to say if they ca n’t prevent it , we ca n’t either , but there are things we can do to make it less likely to occur .
The goal is to reduce the identification number of pathogenic fungi and class Oomycetes by avoiding status that help them thrive .
Allthe canonical good practice for indoor seeded player startingcan help . This includes sowing seeds at the recommended depth , ply the right amount of water ( not too much or too little ) , undecomposed air flow ( O ) , suitable room and land temperature , adequate spark , nutrient , and so on .
Here are some preventive step for the future :
1Clean Your Supplies Before Use
Always cleanse your creature and tray with max , water , and household bleach .
Disinfecting With Bleach (Sodium Hypochlorite)
The Center for Disease Control(CDC ) recommend :
surcharge or spray any hard ( non - porous ) itemsfor at least one minutein a bleach root using household bleaching agent ( 5 to 9 % sodium hypochlorite ) and board temperature water .
Also note that bleach solutions will not be as in effect after being mix with water for over 24 hour . .
2Use Potting Mix or Seed Starting Mix
We useorganic potting mixor “ sterile”seed embark on mixfor seed starting because they provide several welfare over garden soil .
While it ’s a stretchiness to think they may truly besterile(and spore - free ) in the bag , they most sure enough are not sterile once the bagful is open ( remember , spore are everywhere ) , but they are still better than garden soil for several reasons . These bagged commixture will have fewer pathogens , be less hospitable to them , and eliminate some other stressor that seedlings can face .
3Avoid Damp Conditions
Both kingdom Fungi and class Oomycetes typically thrive in wet conditions .
Ensure your growing containers have drain hole to keep water from pooling .
pee enough to keep soil moist but not damp .
If you utilize humidity domes , do n’t overdo it . Domes can assist retain wet during germination but on-going use encourages excess humidity and wet . Once your seed sprout , keep the domes off .
Adequate humidness levels are crucial for plantsbut you could overdo it .
4Provide Good Airflow
miserable airflow is an invitation to pathogens .
cut out your seedlings to allow good air flow between plants .
Set anelectric fanto circularize air over your seedling each day . I put the fan on the sametimerthat runs my grow light ( roughly 12 hour a day ) .

What To Do If You Suspect Damping-Off
If your seedlings are dying and damp - off is to blame , they are not go to go back .
