Planting & Care for Ludwig Spaeth Lilac Shrubs
Preparation
- Lilac shrubs flower best in full sun, but they do tolerate light shade.
- Choose an open site, protected from strong, drying winds.
- Pick a spot in your landscape where air circulates freely, but not overbearing. This will reduce the risk of leaves becoming mildewed.
- Lilac shrubs need well-drained, organically rich soil.
- Avoid chalky spots, which may cause lime-induced chlorosis (leaves turn creamy yellow and die).
Opening Plant Material
- Container - Completely saturate all container plants by putting in a larger container of water until stops bubbling, then remove the plant from the container.
- 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.
Planting Container
- 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.
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.
Pruning - After Planting
- Container - 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.
- 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.
Pruning - Through-out the Season
- Prune Lilac shrubs in November & December.
- Cut out spent flowers when petals fade.
- Keep bushes youthful and blooming freely by pruning out a quarter of the oldest shoots each year in winter.
- Remove any basal suckers.
Watering - After Planting
- Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as oft en 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.
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.
