When shopping for your winter veggie plants at the nursery make sure you are picking out the healthiest plants to ensure the best production.  Look for plants that are wider than they are taller.  6 or more leaves per plant is ideal.  Leggy plants indicate over growth, can be root bound and stressed.  All these factors will make the fruit production difficult.  When pulling the seedlings out of the packaging slightly, the roots should be bright white.  Even though it might be tempting to buy a plant with a fruit already producing, resist!  It actually indicates the seedling has been in the container too long.
