Step-by-Step Guide

Begin by observing your landscape's microclimate, soil type, sun exposure, and drainage patterns to determine the most suitable plants and landscape design.

1. Walk around your yard and note areas with full sun, shade, wet, or dry conditions.
2. Test soil pH and drainage to understand soil health and suitability for different plants.
3. Identify existing landscape features and structures that influence plant placement.

Select native or well-adapted plants that thrive in Hawaii's climate zones, considering factors like mature size, water needs, and soil preferences.

1. Use local native plants that are adapted to Hawaii's environment to improve resilience and reduce maintenance.
2. Avoid invasive species that can disrupt local ecosystems.
3. Group plants with similar water, light, and soil requirements for efficient care.

Adopt efficient watering practices to conserve water and promote healthy plant growth, especially during dry periods.

1. Group plants by their water needs for hydro-zoning, and use separate irrigation zones accordingly.
2. Water deeply and infrequently, aiming for about half to three-quarters of an inch per session to reach the root zone.
3. Water in the early morning to reduce evaporation and fungal issues.
4. Use rain sensors and soil moisture sensors to avoid overwatering, and calibrate sprinkler systems regularly.

Use organic mulch to improve soil health, conserve moisture, and suppress weeds, ensuring mulch does not touch plant trunks.

1. Apply a two to three-inch layer of mulch around trees, shrubs, and landscape beds.
2. Pull mulch away from the trunk to prevent insect and disease problems.
3. Select organic mulches like bark, straw, or pine needles over inorganic options like gravel or rubber mulch.

Create habitats that support native birds, pollinators, and other wildlife by planting flowering plants, providing water sources, and maintaining natural features.

1. Plant a variety of native flowering plants and larval host plants to attract pollinators and butterflies.
2. Increase vertical layering with ground covers, shrubs, and trees to provide shelter and nesting sites.
3. Install bird baths, small ponds, or water features to support wildlife hydration needs.

Monitor plants regularly for pests and diseases, and use targeted, least-toxic treatments to minimize environmental impact.

1. Identify pests accurately before applying controls.
2. Encourage beneficial insects like ladybugs and praying mantises to naturally control pest populations.
3. Use organic or biological pest control methods such as insecticidal soaps or Bacillus thuringiensis when necessary.

Compost leaves, grass clippings, and kitchen scraps to enrich soil and reduce waste in landfills.

1. Create compost piles or bins for yard and kitchen waste.
2. Use compost as mulch or soil amendment to improve soil fertility and structure.
3. Incorporate organic matter back into the landscape to support plant health.

Implement landscape features that retain and filter stormwater, helping to prevent pollution and erosion near water bodies.

1. Install rain gardens or swales to capture and absorb runoff.
2. Use permeable materials for driveways and walkways to promote water infiltration.
3. Keep fertilizers and yard waste out of storm drains and water bodies.

Maintain buffers of native vegetation along lakes, ponds, and coastal areas to prevent erosion and filter pollutants.

1. Plant native grasses and shrubs that stabilize shoreline soils.
2. Avoid fertilizing or applying chemicals near water bodies.
3. Establish low-maintenance vegetative buffers around water features to support habitat and water quality.

Pro Tips

Maximize landscape resilience and reduce maintenance by selecting native and drought-tolerant plants, and regularly monitoring your landscape’s health.

1. Use local native plants that are naturally adapted to Hawaii’s environment to minimize watering and fertilization.
2. Incorporate rain harvesting and graywater reuse to reduce dependence on municipal water sources.
3. Maintain proper soil health through composting and organic amendments to promote vigorous plant growth.

Best Practices

Adopt sustainable landscaping techniques that protect Hawaii’s natural resources and promote biodiversity.

1. Plan landscapes that mimic natural ecosystems with layered plantings and native species.
2. Apply fertilizers and pesticides only as needed and in accordance with local regulations.
3. Regularly inspect and maintain irrigation systems to prevent waste and ensure proper functioning.
