The optimal planting period for loblolly pine bareroot seedlings spans from early December to March 1, considered the dormant season.
However, the planting timeframe for containerized seedlings can be extended beyond these dates if soil surface and moisture conditions are favorable.
ArborGen customers typically engage in planting activities within this window, concentrating in January and February
The question arises: why does early planting contribute to enhanced survival and growth?
Planting bareroot seedlings during the early months, specifically from December to February, increases the likelihood of improved survival rates for most pine species.
This advantage stems from the seedlings having a head start in developing new roots and establishing themselves before the initiation of new top growth in the spring.
A bareroot pine seedling requires approximately 4 to 6 weeks to grow new roots following transplantation under optimal soil moisture conditions. Seedlings planted in December to mid-February benefit from ample time to cultivate new roots before the spring flush.
On the contrary, later planting may not afford seedlings sufficient time to develop new roots before the emergence of shoots and the rise in temperatures.
Inadequate root development can lead to suboptimal water and nutrient uptake, potentially resulting in seedling dieback or mortality when faced with the stresses of summer heat and dry periods.
To ensure robust survival and optimal first-year growth for your new seedling, check weather forecasts to avoid freezing temperatures and ensure adequate soil moisture. Additionally, ensure that mechanical and chemical site preparation is conducted well in advance, allowing beds sufficient time to settle and prepare the site adequately.
Call your tree planter or consultant and let them know you want to plant your seedlings early so they can get the crews lined up to be on your site as soon as possible.
