  • Planting

    1. Dig holes or beds wide, not deep
    2. Lightly amend heavy clay or sandy soils with organic matter
    3. Gently remove plants from containers, keeping the root ball intact
    4. Loosen potting soil and roots around bottom and edges of root ball
    5. Plant level with surrounding soil, spreading roots outward
    6. Fill around roots with lightly amended native soil
    7. Water to settle soil around roots
    8. Cover the area with leaf or bark mulch 1 - 3 inches thick but not piled up onto the plant's stem/trunk
    9. Water deeply
    10. Stake large shrubs or trees to prevent excess movement in strong winds

  • Watering

    1. Woody plants need watering less frequently than tender annuals or herbaceous plants
    2. Most established trees, shrubs, and vines can go weeks without supplemental watering except in extremely hot or windy weather
    3. Watering from a hose or sprinkler should be done slowly and deeply, not frequently, to avoid shallow root development or root diseases. Allow soil to dry several inches deep before irrigating
    4. When practical, especially in arid climates, use and maintain water-efficient soaker hoses or drip irrigation. Water briefly two or three times a week to keep soil moist, not wet
    5. Most winter injury is from drying out, not cold temperatures. Be prepared to water during prolonged sunny, windy, dry spells even in the winter.
    6. Mulches help prevent water loss during hot, windy, or sunny weather

  • Pruning

    1. Prune for size control and pedestrian safety, to remove dead or diseased plant parts, or to shape or train plants into hedges, topiary, espalier, or other interesting shapes
    2. Avoid pruning needled conifer plants hard - unlike broadleaf plants, conifers generally don't sprout new growth from stems cut back to bare areas. Shear new growth only

  • Propagation

    1. Needled or conifer plants root best in summer by taking cuttings from partially-mature new growth and inserting them into well-drained soil and kept moist, not wet.
    2. Some may take a year or more to root.

  • Fertilization

    Most plants need a regular "diet" of all-purpose plant food, either specialty (labeled for your specific plant type) or a generic N-P-K (nitrogen - phosphorus - potassium)

    Fertilize early in the plant's growing cycle - spring for summer plants, fall for winter plants

    • For leafy plants, use a fertilizer with a higher nitrogen content (first number)
    • For flowering or fruiting plants, use a fertilizer higher in phosphorous content (middle number)

    If using a water soluble fertilizer:

    1. Mix as directed on container according to directions
    2. Wet the leaves and drench soil
    3. Repeat

    If using a granulated fertilizer:

    1. Scatter a small amount of all-purpose fertilizer lightly under plants from the stem to beyond the outer spread of branches or foliage
    2. Water slowly and deeply

    NOTE: Never over fertilize! You will see lots of weak, leafy growth and few flowers
