Planting & Care for Hydrangea Plants/Shrubs

Preparation

  • These shrubs need damp soil high in organic matter.
  • Improve poor soil areas by digging in plenty of well-decayed manure or compost a few month ahead of planting.
  • Hydrangeas can be planted March-November.
  • Pick a spot that has dappled sunlight or morning sun and afternoon shade.
  • Make sure they are sheltered from frosty winds, which will damage blossoms.

Opening Plant Material

  • Completely saturate all container plants by putting in a larger container of water until stops bubbling, then remove the plant from the container. 

Opening Plant Material

  • Bare Root - Cut open the bundle (top and roots are tied) and separate all the plants. Soak roots in buckets of water until planted. Each plant type will be labeled separately for identification. Do not expose the roots to sun. They should never dry out. Keep roots covered. All bare-root plants must be trimmed when planted. 
  • Containers - Completely saturate all container plants by putting in a larger container of water until stops bubbling, then remove the plant from the container. 

Planting Bare Root

  • Dig a hole at least 6" wider and the same depth as the root mass. The crown or graft of the plant should be slightly higher than ground level where it was grown at the nursery.
  • Trim off the broken roots and branches.
  • Place fertilizer packets in hole (if purchased). Do not place other fertilizers in the planting hole. *Use Our Recommended Fertilizer.
  • Spread the roots and fill halfway with soil, then water until soil settles completely saturating the soil and planting pit.
  • Re-adjust plant and fill the hole with the rest of the soil.
  • Back fill the balance of the soil and water well. 

Planting containers

  • Lilac Shrubs can be planted in March-November
  • Dig a hole no deeper than the depth of the container and 6" or more wider on the sides.
  • Slide plant from pot by tapping on the bottom of the pot.
  • With shovel or knife trim bottom 2" off of the root ball for plants in plastic containers.
  • Rotate the plant to the proper position. Never lift or move plants by the tops.
  • Place the root ball in the hole.
  • Adjust the plant height so the root crown is slightly higher than the ground.
  • Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer
  • Back-fill the hole with soil, making sure the top of the root ball is visible and slightly higher than the soil around it.
  • Firm the soil around the plant. Water well to settle soil around the root ball.
  • Water frequently when newly planted. 

Pruning - After Planting

  • Bare Root - Prune ALL bare root plants to reduce transplant shock and ensure success. Pruning should occur either before or as soon after planting as possible. All pruning should be done with a sharp pruning shears.
  • Containers - Although it is not essential for container plants to be pruned after planting, a light pruning to remove any broken branches during shipment and improve shape will help the looks of your new planting.

Pruning - Through-out the Season

  • Follow these pruning tips for your specific type of hydrangea: 
  • Hydrangea macrophylla - Cut off spent flowers in spring and remove crowding shoots. 
  • Hydrangea paniculata – Prune stems to within two buds of the base in late March.
  • Hydrangea petiolaris – Cut out unwanted shoots when flowers fade. Remove a third of older stems in sping.

Watering - After Planting

  • Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
  • Beyond the 6 week establishment period, water once per week, unless rains occur.
  • Stick your finger into the soil around 3” to check soil moisture.

Watering - Through-out the Season

  • After the first season, plants should only be watered during extended periods without rain.
  • How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
  • Stick your finger into the soil around 3” to check soil moisture.

Special Plant Features & Tips

  • Plant March-November
  • Apply acidifying fertilizer like sulfate of ammonia in spring and midsummer to ensure a steady release of plant foods and encourage blue flowers.
  • Make sure they are sheltered from frosty winds. Make sure to always check the label before adding anything to your soil. 
  • These may not bloom on new wood. 
  • Excessive lime prevents chlorophyll from forming and causes leaves to yellow and die. Overcome it by applying iron chelates.
  • Mass or group in part shade areas of the mixed shrub border, woodland garden or as background for a perennial border. Naturalize in woodland or native plant gardens. Named cultivars often make showy specimens.
