Fish blood & bone, can it kill plants?

Hey Everyone,

So I'd stupidly decided to add a little fish blood and bone to my bamboo seedlings along with a few other indoor potted plants.

Days later all the leaves on all plants look like they're dying and curling up after being totally fine for a few months. Is this something caused by the fish blood and bone even though it's natural fertilizer?

I did repor them in fresh compost a few days ago but it may be too late!

 

Yes it can scorch mature plants if over applied . It highly likely Seedling will be scorched even if you haven't over applied, you don't really fed seedling just pot them on into fresh compost which has plenty of nutrition for them .

 

Thanks. Just hope I wasn't too late changing the compost now

 

Hi,

For the Seedlings probably too late, plus even if they do recover, given such a damaging check it would be better to start some new ones off.
For the other established pot plants, just cross your fingers and hope !

What about the compost you are using, is it a decent commerical brand ?

As @Perki says most composts have enough of the correct level of food in them to last for about 6 weeks before you need to add anything other than water.

After that time use a liquid measured feed eg for a few house plant a bottle of Baby Bio, typically just once a week but generally not in winter when most plants are semi dormant and need little water or feeding.
