Here are several tips for creating a wonderful hanging basket or container this summer. The first is to use an artificial soil composed mostly of peat moss. Good soils such as Fafard or Pro-Mix use perlite, peat, and other ingredients to produce a soil that will not compact over the summer. Real garden soil compacts and turns into concrete under the pressure of regular watering. And when it does, plant roots stop growing because they require good open spaces to move into and absorb nutrients. Hard, compacted soils do not grow good plants so do not use real soil in your containers. I re-use my artificial potting soil from year to year. I dump it out of the pot. Chew it up with a shovel to cut up all last year
