PJ,
What kind of soil do you have? If it has lots of humus drains well, you should have no problems planting them directly in the ground, but if the soil is less than ideal, planting the rooted cuttings in small pots in potting soil gives the cutting a chance to establish a larger root system quickly before it has to go in the ground.
Amend a large area where the Brug will be planted rather than just the hole or you will get the bathtub effect. If there is a difference between soil types, water takes longer to penetrate from one soil to another. Standing in water for too long without access to oxygen, can lead to root rot. Strange since they can be started in water, but it happens all too often.
Peroxide added to the rooting water not only keeps the water fresher for a longer period, it also provides more oxygen to the cutting.
Last year, I experimented with a tiny bit of rooting gel I had. I added a very small amount to the rooting water. It didn't seem to have the same effect on all the cuttings I was rooting, but I was astonished at the rate some of the cuttings rooted.
