I fed my roses at the start of May... when should I next feed them? Googling seems inconclusive, so I'd prefer advice from those who actually have roses!
Standard practice after the first flush of flowers geum. If theyre repeat flowerers theyl come again. Second flush is never as good but almost. I mulch and water as well.
I'd suggest no later than early July otherwize feeding will encourage some nice tender new growth as well as flowers and you need the ferts to wear off a bit and give the new growth time to mature to survive winter frosts
By all means give a nice mulch in the autumn, but I'd not put a rose feed on in autumn
Lovely, thank you for the advice!
