good to know

What 9B means for your plants

  1. 1

    Plant in the cool season

    October to February is ideal. Summer plantings struggle in the heat.

  2. 2

    Afternoon shade is gold

    Even sun-lovers appreciate shade from the hottest hours in July and August.

  3. 3

    Chill-loving plants struggle

    Lilacs, tulips and many peonies need cold winters. Choose low-chill varieties or pre-chill bulbs.

  4. 4

    Water deeply, less often

    Deep, infrequent watering trains roots to go down where the soil stays cooler.
