interplanting with Alliums
Hi all, I'm a farmer and have decided to plant some alliums in a 50'x3' bed, different varieties of Alliums, from small to large. But I would like to underplant them with some perennial flowering plants valuable as cut flowers to assure a longer presence of flowers throughout the season and to hide the yellowing leave of the alliums. I'm planting in rows, should I plant a later maturing plant in front of the allium rows? What is the actual technique and spacing of interplanting? How do I plant and avoid to interfere with each other?
