Dry soil
• What is dry soil?– Anoka County Sand Plain– Spaces between grains of sand are
large– Water leaches easily, soil dries out
fast– Low ability to hang on to nutrients
• Gardening in dry/shaded areas– Amending with 3-6” organic material– Apply 3” of mulch to keep soil moist– Fertilize more often– Space plants farther apart – Stake tall plants as they will grow
toward the light– Do not put additional soil over tree
roots

Dry Soil:Annual Foliage Plants
• Foliage plants are invaluable for obtaining an attractive colorful look.
• In a container, foliage can reinforce a color theme or blend the disparate elements of various bloomers.
• In the ground, annual foliage can carry a summer display through the quiet times between perennial flowering periods.
• Plants listed may be perennials in other zones, but are used as annuals in our northern gardens.
• A word about establishment: Initial care must be taken to establish the plantings for the first two weeks, whether from seed or bedding plants.
• They require only light watering however; DO NOT overwater or plants will be floppy and disease-prone.
• Unless indicated these prefer full sun and average soil conditions of fertility, drainage, and pH.
