Hi Breezy we also do roses in eco vase but we put in cello fill up with water and tie firm but with enough room to allow flowers/foliage foliage in first and then flowers or in this case roses very quick to make and elimnate the need for oasis only problem is you don't have cello on top and therefore flowers have no protection from weather or banging about during delivery much prefer to spend more time and make proper handtie.
