Transplant seedlings outdoors after the last threat of frost. For us in south-central Indiana this means early-mid May. These are bare-root transplants. The plant will root from each node on the stem, so the basic idea is to bury the stems and just leave a bit of the stem and leaves above ground. While not pictured here, once transplanted I now lay drip tape over the seedlings. The tape eventually gets buried as the plants grow and soil is mounded up around their stems to promote more rooting and to keep weeds down.
