Do Dahlias Like Manure?

It is well known amongst Dahlia growers that they like a lot of fertiliser, but does this apply to manure? Do dahlias like manure or should you use something else to feed them?

Do Dahlias Like Manure?

Dahlias don’t like to dry out so something like manure as a mulch will work really well. For lots of flowers though Dahlias need potassium (potash).

Manure tends to be a high nitrogen fertiliser so isn’t ideal for flowers. Nitrogen promotes leafy growth but you need more potassium for flowers.

For lots of potash you can use fish blood and bone or alternatively a tomato feed will also work well.

I like to use this organic feed below for everything in my garden, just dilute some down in a watering can and away you go.

More on Dahlias

Dahlias are simply stunning summer flowers, the pop pop head produces amazing displays. The plant is a member of the Asteraceae family along with daisies, asters and marigolds.

Usually grown from a tuber but they can also be grown from seed. The tubers require special care over winter here in the UK and many growers end up with an almost fanatical devotion to their dahlias.

Despite being unable to survive winter outdoors in most of the UK, they thrive in our summer conditions. The moderate but wet climate we have is absolutely perfect for them.


Dahlias make the perfect container flower and are commonly grown this way. Growing them in containers also makes preserving the tuber over winter a lot easier.
