A bare root tree is a plant, typically a young deciduous sapling, that is harvested while dormant and shipped with no soil attached to its roots. This method allows for inexpensive mass production and easy transport, making the trees a seemingly budget-friendly choice for growers and homeowners. However, purchasing a tree in this state introduces several risks and logistical challenges that often undermine the initial cost savings. The minimal protection afforded to the root system significantly elevates the chance of tree failure after planting.
Risk of Root Desiccation
The most significant threat to a bare root tree is the rapid drying out of its exposed root system, a process known as desiccation. Tree roots, particularly the fine, non-woody feeder roots responsible for water and nutrient uptake, are highly sensitive to air exposure. These delicate root hairs lack the protective waxy cuticle found on above-ground stems and leaves, making them extremely vulnerable to moisture loss.
Even brief exposure to air, wind, or sunlight can irreparably damage these absorptive tissues, effectively reducing the tree’s capacity to hydrate itself once planted. This damage is often not immediately visible, but the compromised roots fail to support the canopy once the tree breaks dormancy months later, leading to delayed decline or death. The lack of a surrounding soil mass means the roots have no buffer against environmental changes during shipping and handling. This condition stands in sharp contrast to container-grown or balled-and-burlapped stock, where the soil maintains a stable, high-humidity microclimate. Therefore, maintaining root moisture from the moment the tree is dug up until it is planted is a non-negotiable requirement for bare root stock survival.
The Narrow Planting Window
Bare root trees impose a strict and unforgiving logistical constraint on the purchaser due to their requirement for planting while fully dormant. The species must be placed in the ground before its buds begin to swell and leaf out, which typically confines the planting window to a few weeks in early spring. This narrow timeframe forces the buyer to plant immediately upon receipt, regardless of weather or personal scheduling conflicts.
This urgency contrasts sharply with containerized plants, which can be held for weeks or even months before transplanting, offering much-needed flexibility. If immediate planting is impossible, bare root trees require specialized, cool storage, ideally between 33 and 40 degrees Fahrenheit, in high humidity and darkness. Improper temporary storage, such as placing the roots in a warm garage or allowing them to freeze, rapidly compromises the tree’s viability. When storage must be prolonged, a process called “heeling in” is sometimes necessary, which involves burying the roots temporarily in a trench of soil or moist mulch. This demanding process is a significant chore for the average homeowner and emphasizes the high risk involved in managing this type of stock.
Inability to Assess Root Quality
A significant disadvantage for the consumer is the difficulty of thoroughly inspecting the root quality before the transaction is complete. Bare root stock is typically sold bundled in plastic or moist packing material, making a detailed pre-purchase assessment nearly impossible. The buyer is often taking a chance on the root health, structure, and integrity, which may conceal pre-existing damage or disease.
Upon opening the package, the buyer may discover roots that are limp, brittle, or discolored, which indicates desiccation or fungal issues that occurred during transit or storage. Furthermore, structural issues like severely girdled roots, which circle the trunk and slowly strangle the tree, may be present but hidden by the bundling. The inability to thoroughly check the roots shifts the entire risk of purchasing poor-quality stock onto the buyer. By comparison, a container-grown tree allows for a quick inspection of the visible root flare and often the overall root structure by gently sliding the plant out of its pot. The obscured nature of bare root packaging means the buyer often only realizes the full extent of the root problems once the tree fails to thrive months later.
Limitations on Species and Maturity
Not all tree species tolerate the bare root process equally well, which significantly limits the buyer’s selection. Evergreens and large conifers retain their needles and continue to lose moisture throughout the winter, making them highly susceptible to desiccation when sold without soil. Similarly, species that rely on a deep, single taproot, such as certain oaks, hickories, and walnuts, often struggle with the significant root pruning inherent in the bare root digging process.
These sensitive species typically require the greater protection afforded by a container or a balled-and-burlapped method to ensure successful transplanting. Furthermore, the bare root method is generally restricted to smaller, less mature stock, usually seedlings or trees with a trunk diameter (caliper) of two inches or less. Larger, more established trees cannot be successfully moved without a substantial soil ball to protect their extensive root systems. This limitation means the buyer must accept a significantly smaller, younger tree that will take more years to mature, in addition to the increased risk associated with the bare root handling requirements.
