dry soil

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

• Alkaline Soil• Annuals 3 Feet or More• Annual Vines That Grow Quickly• Boulevard Gardens: Perennials• Boulevard Gardens: Small Trees• Broadleaf Evergreens for Zone 4• Clay Soil• Cold Tolerant Annuals• Compacted Sites: Trees• Crevice Plants• Deer Resistant Plants• Dry Soil: Annual Foliage Plants• Dry Soil: Shade or Under Trees• Dry Soil: Trees• Fragrant Annuals and Perennials• Fragrant Shrubs• Indoor Low Light• Knot Gardens• Lakeshore Native Plants• Long-Blooming Perennials• Rain Garden Plants• River Banks and Canoe Public Access Areas• Self-Seeding Perennials• Septic Mound Plants• Shade: Shrubs• Shade: Small Trees• Shade: Tall Perennials• Steep Slopes• Trees that Produce Minimal Litter• Under a Black Walnut Tree

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.
