Slow New Dawn Rose growth
My New Dawn Rose, which I bought in February to train underneath the base of the windowsill is taking its time to grow. It is in a large pot with some ranunculus. The ranunculus are still in their plastic containers but buried in to prevent the pot being too bare! I have been giving it a weekly mixed fertiliser/high nitrogen feed and water but still little heigh growth. The plant has flower buds so it can’t be too unhappy but I want more growth ASAP!
Any advice would be great!
