What Is Blanket Weed?
If you have not yet come across this nuisance, congratulations! Blanket weed or long string algae is one of the most well-known (and hated) pond weeds in the UK. It is a long thin alga that has no leaves, stems or roots and forms large, dense pillows of green weed that float around the top of your pond and attach themselves to the side walls. Blanketweed thrives in ornamental ponds with pumps due to the exposure to sunlight, flowing water and abundant nutrients available.
Is Blanketweed Dangerous?
Short answer, yes it can be dangerous to your pond and its habitants.
As well as competing with your plants, blanket weed will compete with fish for vital oxygen which could lead to your fish dying through lack of oxygen. Not only can the blanket weed deprive fish of much needed oxygen, fish can sometimes swim into the blanketweed, get stuck and then not be able to free themselves and eventually dye.
How to Remove Blanketweed
It is not advisable to remove living blanket weed as this will cause the weed to release spores into the pond which will in turn, create more blanketweed. We suggest treating your pond firstly with Pond Equaliser to get your ponds water quality perfect and then using Blanketweed Klear. Blanketweed klear is easy to use, simply scatter it on the blanket weed, wait for it to die and then scoop out the dead weed and either throw it into your garden waste bin or composting bin. Blanket weed is full of nitrogen which is good for composting.
After you have removed the blanket weed from your pond you will want to do everything possible to prevent it from returning in the future. Be sure to have lots of aquatic plants that will absorb excess nutrients in the pond. Keep your fish stock in line with the size of your pond, too many fish can lead to excess waste being produced which can create even more excess nutrients. Check your water quality regularly with a test kit and keep your pH, KH & GH levels balanced.
