Common lilac 'Ludwig Spaeth'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Ludwig Spaeth is thought of as hardy, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea). Planting Ludwig Spaeth in loamy and clay soil with a ph of between 6.0 and 7.5 is ideal for as it does best in weakly acidic soil to weakly alkaline soil.

As Ludwig Spaeth is hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
