can i re use garden compost
Do you mean compost from plant pots or compost you made?
Both can be put into borders in your garden.

I do not reuse my spent compost as there is no goodness left in it for growing more plants. I throw mine on the garden as Kildermorie says.
That is what we tend to do too... though Bulba has been know to reuse having added more nutriments first.
As above, although some gets chucked in the compost bin too.
If I've grown sweet peas in a container I have re-used this soil for young plants.

A sweet pea grower myself, I am interested in why you do this Meanie?
All Legumes are good at putting nitrogen into the soil.
Out of desperation one day when pricking out Lobelia Queen Vic seedlings I used this redundant compost and got great results.
I have a Lathyrus sativus azureus which has been grown for seed which is almost harvested, so I'll repeat this with some of the L.tupa which are just germinating and do a comparison.
I thought that must be it Meanie. I happen to think, by the time the plant is finished/dead that it has used up all the nitrogen for itself. I am one of the few people I know who give my Sweet peas a 24% nitrogen feed every 1-2 weeks.
I'll do half in normal potting compost and see if there's any difference.
I worry about disease and infestations, so I like to empty my pots every year and have a good look. Let us know how you get on Meanie.
Nitrogen nodules on plant matter left in the ground we feed nitrogen back into the soil
Sorry can you say that again MG?
Drc you said 'I happen to think, by the time the plant is finished/dead that it has used up all the nitrogen for itself.'
But legumes produces nodules on their roots which store nitrogen, this is why you do not pull up your peas or beans when they are done you cut them down to just above the soil and the nitrogen in the nodules is then released back into the soil.

Thanks for explaining that MG!
So grabbing the less "rooty" matter from the edges after removing from the pot probably had no bearing........
May I point out that I don't do this as a matter of routine, I was just desperate on this occasion. Despite my user name, I'm not a complete tight @ss!!
Thanks MG I wasnt questioning you as such, I just could not understand your last sentence! I do not pull up my peas (the few I grow). But my Sweet peas are in compost in pots and I do not see their can be any goodness left in that?
Well sweet peas have nitrogen nodules on their roots like any other legume so as they decompose the nitrogen goes back into the compost. Other than that though the compost will be pretty depleted.
How do I say thanks?
