Plants can be installed directly into dead sod — By not disturbing the surrounding soil, weed seeds are not exposed, reducing weed growth in the new garden. Whether planting into tilled soil or dead lawn turf, you may cover the soil around each new plant with mulch.
We recommend applying mulch after planting — Mulch helps reduce watering and retain moisture for your new transplants during their establishment phase. Mulch after planting with 3–4 inches of clean, weed-free straw or the mulch of your choice. Bark chips or nuggets are not recommended, as they contain compounds that are toxic to many herbaceous plants.
Watering — During the first two months after planting, water the garden whenever the soil begins to dry out. A single deep soaking is better than numerous light sprinklings. Once the plants are well-established watering should not be necessary, except during periods of extended drought.
