Pine Cone Mulch - an attractive border and maybe a practical way to keep dogs and cats out of your garden beds. As they breakdown, they will add nutrients to your garden too. Pine cones also look great as a decorative mulch for container gardens.
All you need is a small amount of vertical space around a balcony or an open window which can hang or store a vertical array of drink bottles that can grow all your herbs and lettuce easily. Recycle as many of your plastic drink containers.
