Good questions grow here
A little more clarity.
Do Lilac seeds need cold stratification?
Yes — Lilac seeds are raw and untreated, so they need a cold, moist rest to break dormancy. Mix them into the damp soil, cover with the lid, and chill the planter in the refrigerator for several weeks, then move it somewhere warm and bright.
How long do Lilac seeds take to germinate?
Lilac seeds typically sprout in 30-60 days at 33-40F when kept warm and evenly moist. Your guide lists the ideal conditions.
Growing details are supplied in the Seeds In A Cup® product catalog. Follow the instructions included with your specific kit.
