Thank You,newt, for the suggestions on the types of plants for bug and hummingbirds,the information will be helpful on the next planting.
Natural Cat, it saddens me to read this.* You must be near a busy road or highway.* Planting a diversity of plants will attract more insects.* Planting plants that have 'landing pads' will attract beneficial insects.* Those would be plants with flat tops to their blooms and simple flowers, not the doubles.* Tubular shaped flowers and red or purple flowers will attract butterflies and hummingbirds.
