I know this thread is an old one, but I wanted to ask does anyone know if the blood fish and bone is harmful to the earthworms and centipedes, in turn birds?
I had some BFB given to me, its quite old I think but I sprinkled it on two veg beds today in anticipation of heavy rains tomorrow, it didn't occur to me till after that it may not be a good thing for the earthworms, birds etc.
Hope someone can advise.
It will be absolutely fine when used as directed on the packet. Chucking a whole packet directly onto a worm, centipede or at a bird would be the only way I could see it harming them!
The worms absolutely love it. They will eat anything that has lived.
Only too happy to help the gardeners friends thanks Edd
Artificial fertilisers can damage worms and also burn up carbon in the soil. Unfortunately even organic based fertilisers can burn up carbon. The simple solution is to use plenty of compost to raise carbon levels as well as Fish Blood and Bone. Biochar is also an option for increase soil carbon but quite expensive at the moment. Another option to think about is to plant a mustard and clover mix on spare beds as this will increase the carbon and the nitrogen in the soil, leading to better yields.
Fish blood and bone is slightly more expensive, but its slower acting and this can be an advantage as plants don't go to lush and become targets for aphids.
Combined with seaweed feeding you will get superb plants. Unless the slugs eat them, but thats another story...
you are correct Simon. Artificial fertilisers like Gromore do harm worms when they come into contact with it. Years back I noticed this and stopped using Gromore. Fish blood and bone is more gentle, feeds soil and encourages life in it. The only proviso is where foxes, badgers are present...they smell the fertiliser and dig for it. agree again with Simon about seaweed ...the best of all fertilisers if you can get hold of it in bulk
Even bulk prices its like £2+ a kilo (for seaweed meal). But that about enough for 20 square metres, so 10p a square metre price. Worth it for high value areas like raised beds, fruit gardens and so me rose and perennial flower gardens too.
I bet it would be worth piling compost over fish blood and bone, to stop the smell and stop the digging.
Just "tickle" fish blood and bone into the soil surface Simon
Thanks Simon and Verdun,
Simon where do you buy your seaweed meal, what make etc?
I used to have visions of going to the ocean to bring back bags of seeweed, but didn't fancy the other organisms I might be travelling back with in the car lol
Jade, I used to do just that. Bags full of seaweed with all sorts of jumping, leaping and crawling creatures. Mind you they tasted good with my cheese sandwiches .
If you want a lot of seaweed, LBS trade horticulture is good for wholesale prices. You have to ask for a trade account. Just tell them your starting a plant nursery. They are happy to let you have a trade account. And delivery is free when you spend £125 + vat.
Make is Maxicrop, price from £52+vat to £44.65+vat if you buy 6 (25KG bags)
Personally I mix it 50/50 with FBB and add 200 grams per square metre. Then with heavy feeders give a second dose of the FBB. As well as plenty of green waste compost.
if you just want one bag to try it then http://www.rigbytaylor.com/ can sort you out.
Many thanks Simon
