Why is it ok to plant a new rose next to an old rose , but you can't plant one where an old rose has been even if it didn't die of disease?
Can you pull out a healthy rose that has fallen out of favour and replace it with a new one without sprinkling that stuff on it?
In London. Keen but lazy.
I would replenish the soil, adding lots of well rotted farmyard manure and fish blood and bone - then I would happily replace one rose with another - but I would also use mycorrhizal fungi when planting - it has been shown to result in better root growth and stronger healthier plants.
I have a packet of that MF stuff somewhere, but bfb is out of the question unless I want the foxes to rearrange my garden!
Ah! Then some good general purpose slow release fertiliser - Growmore pellets maybe?
Does anyone else have another suggestion?

B3, rose's are what's called ' gross feeders'. They can quickly deplete surrounding soil of nutrients and essential minerals, hence the term ' rose sick' soil. That's why feeding regime's are important for rose's. Personally I wouldn't use growmore but use fish bone and blood added to the planting hole. You can lay some chicken wire around the base to stop the foxes digging it up.
I usually dig out a barrow load of soil and swap it with a barrowload from the veg garden when planting a new rose where an old one has been, then dig in organic rose fertilizer and manure.
That makes sense, Dave. I thought that maybe they contaminated the soil in some way.
Good idea busy. I will instruct the undergardener
I'll chuck something non-organic in the hole dove.
