How Many Litres Of Compost Do I Need To 3/4 Fill A 100 Gallon Container?

[Tilly2]

This is for my new waterfeature venture.

[bhg481]

4.546 litres to a gallon so

4.546 x 100 x 0.75.

[Tilly2]

That's a lot of bags of ericaceous compost!

[bhg481]

100 gallons is quite a large container. Watering cans are around 2 gallons, so 50 watering cans. Are you sure it's not a 100 litre container?

[gingejbee]

^my thoughts, too. For comparison, a normal round poly rubbish bin is about 80 litres.

[Tilly2]

It was a fish pond and has a 100 gallon capacity.

Oh...then 350-ish litres of compost it is, then.

[bobbinwales]

That's the volume yes...but does it all need to be shopbought compost though and other all ericacious? Could some just be cheaper soil and maybe some stone rubble

[Atheist]

I make it 341 litres. But that's probably not realistic, as compost sold in x litre bags is often rather dry; when it is moistened for use it probably expands. You could order 7no. 50-litre bags and see how it goes.

I want to grow Heathers in it.

[bobbinwales]

Heather's usually OK on rock filled soil but yes ericaceous helps alot....maybe a gardener can advise but I think you will need some rocks stones or bits of broken plant pot and maybe sand to help drainidge with mix of soil and composts under and around the base of the heTher

[Atheist]

You'll need to drill drainage holes in the bottom of the pond, otherwise the plants will be waterlogged.

[Tilly2]

Thats all done, Atheist. Just waiting u till I'm better before continuing.

Stut - you've used US gallons.

[Chipchopper]

A lot!, it will cost a small fortune to fill a space like that with ericaceous compost, and I don't think it's necessary.
The bulk of it could be filled with hardcore / gravel. When you see heather growing on the moors, it's usually on thin soil over rocky ground.
Btw get well soon!

[bhg481]

stut you're still talking US gallons. A UK gallon is 4.546 litres.
