If you have a black walnut tree in your yard...you may have trouble planting under it.In today's Melinda's Garden Moment, some tips on how to overcome that challenge.Part of the fun or for some the frustration of gardening is overcoming challenges and one big challenge for many gardeners is planting under a black walnut tree.All parts of this tree contain a toxic substance called juglone. One solution is to grow juglone tolerant plants.We have the added challenge of shade. I am including several varieties of coral bells for their interesting shaped and colored foliage. The variegated leaves of the hosta and lungwort help brighten the shade. For height I included variegated solomon's seal.I decided to try my luck with Canadian Ginger. I am using only a few plants until I see if it will tolerate the juglone. The golden moneywort provides a nice contrast.Mix in a few bulbs like squills, snowdrops and winter aconite for early spring color.We added some temporary fencing to protect the new plantings from the dogs that play in the yard.I'm Melinda Myers.
