YardSmart Design - Garden Bed for Wet Area

This garden can be placed in any sunnier area where water tends to accumulate. Shrubs and perennials chosen for this garden enjoy occasional wet periods followed by a dry period.

Water moving into the bed will be slowly absorbed into the soil. This garden is sure to delight with four-season interest all while being a resilient and sustainable mini-habitat.

Minimal maintenance leaves more time to watch the birds and beneficial insects that will be attracted by fruit, pollen and nectar. In July, the Saskatoon produces delicious dark blue edible berries. Colourful foliage in an array of shapes and textures captivates in-between bloom cycles.

Tips for successful planting

Before you begin:

  • Use the YardSmart Planning and Design Guide at calgary.ca/YardSmart to ensure this design suits your yard conditions. 
  • Use a good depth of quality soil.

3 Ways to Remove Lawn

  1. In fall, smother the lawn by covering with several layers of damp newspaper, or cardboard. Top with compost or soil to keep wet. Plant in the springtime.
  2. Dig up the sod, flip it over so the grass is facing downwards, and cover with soil so no grass shows. Let sit for a month. Top with compost or new soil before planting.
  3. Put a 10 cm layer of compost and new soil on top of the grass to smother it. Ideally, wait a few weeks for grass to die, or plant right away ensuring there is no grass exposed after planting.

How to install a garden bed

  1. Ensure the plants and the area to be planted are watered well.
  2. Lay the plants out on the prepared bed following the planting map provided. Space them according to the tags’ description of plant width at maturity.
  3. Dig the holes approximately twice the width of the pot and the same depth.
  4. Remove the plant from its pot and carefully loosen and remove some of the soil so the roots can be spread outwards.
  5. Place plant in hole and fill with soil. Ensure the base of the plant stem is level with the ground. Water well.
  6. Add a layer of mulch, keeping it away from the stem of the plant.

Water requirements

  • Keep perennials well-watered for the first year or two (approx. 2.5 cm water/week or until soil is moist to the base of the root system, 1-2 inches down).
  • Shrubs need regular watering for the first 2-3 years. Use a drip hose spiralled around the root area to irrigate. Every week, 15-20 minutes is sufficient.
  • In following years, all plants will be drought tolerant and only need water after 2-3 weeks of hot dry weather with little to no rainfall.

Reminders

  • Keep soil covered with mulch and remove weeds.
  • Fast growing plants usually require division every 3–5 years.

How to winterize:

  • Leave perennial foliage until spring to catch snow and provide food and shelter for birds and beneficial insects.
  • Fallen leaves make great mulch so can be left in garden beds.
  • For shrubs, water well in the fall until the ground freezes.
