When would be the BEST time to plant a Lilac Tree and a Hibiscus?

They are very hardy, so they are planted in lines as hedges and screens, as well as for visual ornamental design. Lilacs can grow at a medium-fast rate, with two feet a year as being commonplace. With reasonable care, perhaps they can grow faster. Plant them 4 to 6 feet apart when used as a line. Give them a moderate amount of water, and a well-drained soil is preferred. The Lilacs prefer full sun, but they can handle up to half shade without any problem too. How to grow these. Simply stated, these grow best in moist well-drained fertile soils with full sun. Most soils can be alright, but plenty of water and some added fertilizer will improve their growth and survival. If your soils are rocky, heavy clay, or very sandy, then add compost or other materials mixed into the planting spot.


When to Plant Lilacs:





The ideal time to plant lilacs is in the fall after their leaves have dropped off. Do this before the ground freezes or you end up with all kinds of problems. You can also plant lilacs in the spring before their buds start to unfold but this is harder to time correctly. Over wintering gives the lilacs root system a head start in the spring when they begin to grow again.

When would be the BEST time to plant a Lilac Tree and a Hibiscus?
Depends on where you are. A hibiscus should be planted after the temperature is consistently above 55 degrees. Any lower than that and it will not grow until the temps come up, and it may not survive if temps are still getting into the low 40s.
