Q.iceberg roses in pots
I have recently purchased my first icebergs and found after 2 days the leaves turning yellow and black. They are constantly wilting (both the leaves and the flowers). I would like to transplant to a bigger pot. Is this now okay to do it as it is in full bloom?
It sounds like you have little choice. The pots the roses are currently in may be too small and the roots are becoming entangled which leads to them not performing well enough to keep the upper part of the rose healthy. Many roses we buy as bud and bloom are in black pots that are either too small or will become too small in a big hurry. Water the roses with some water that has super thrive mixed into the water before transplanting them to the bigger pots (with drainage holes in them) or better yet into the gardens. Then once transplanted water them with some water that has the super thrive and some root stimulator in it. If you notice the roots growing in the shape of the pots, try to lightly pull them out of that shape just before moving them into their new homes.
