Frequently Asked Questions (FAQs)

1. How do you plant lilac bulbs?

The planting hole should be deep and wide enough to accommodate the plant's root system. Place the top of the root ball level with the surface of the hole. If the lilac is bareroot, the top layer of roots should be a few inches below the surface. When filling in with soil, it is important to water thoroughly.

2. When should lilacs be planted?

The best time to plant lilacs is in late fall before the ground freezes. The next best time to plant is in early spring after the ground thaws.

3. Where do lilacs grow best?

Choose an area with plenty of afternoon sun and well-drained soil. Since lilacs prefer good drainage, planting lilac bushes in slightly elevated areas is recommended whenever possible. Following planting lilac bushes, water them thoroughly and add a layer of loose mulch.

4. Do lilacs spread?

These popular ornamentals produce fragrant flowers in shades of white, pink, blue and purple, and are hardy and easy to propagate. Each season, a lilac bush produces and disperses hundreds of seeds to ensure its proliferation in the following year.
