Rocketliners® are sized, shaped and rooted throughout the pot with strong and responsive roots. Gardeners can expect a finished healthy plant within a single growing season. They have greater fresh root mass and vertical root training which promotes faster finishing times. While it can often take up to 3 years for a shrub or vine to get fully established growing from bareroot, Rocketliners® may only take 12 months, saving you up to 2 seasons of waiting time. Rocketliners® are for gardeners that have busy lives, little time to waste and want to start out with the best planting stock.
