At Bachman's, we want to make sure the plants have a good, strong head start, so we only offer them actively growing in containers. Look for well-balanced plants with strong canes. Container plants can be put in anytime during the growing season. If you are planting a variety that may be marginally hardy for your site, plant it by mid-summer to give it plenty of time to settle in. Choose a site that offers lots of sun and well-drained soil with good moisture retention.
