Tree Seedling Care and Information

100% guaranteed to arrive fresh and healthy! Compliance, care and communication with agricultural departments of the US have been taken to ensure that your tree seedlings will ship without being hindered and thrive without disturbing the environmental integrity of your area. Additionally, we've found success in treating our seedlings with a product that produces a natural reaction to reduce moisture loss in shipping. We also inoculate with a beneficial fungi (mycorrhizae) which promotes survival and growth of our seedlings even in difficult planting conditions. Inoculated tree seedlings will be much hardier against a variety of environmental stresses such as drought, heat and poor soil conditions.

Our greenhouse grows over 25 conifer tree species. If there is a tree species that you don't see here, please let us know and we will check on availability.

The Greenhouse

Our greenhouse grows up to 6 million tree seedlings per year which gives us the opportunity to provide you with fresh, healthy tree favors and gifts for a low cost, available all year round. Containerized plug tree seedlings such as ours, offer flexibility and survivability. The roots remain protected by the soil they are grown in, eliminating shock when transplanting so the tree seedling establishes easily and settles into the soil better. Plug seedlings offer many advantages over bare root seedlings, including high survival rates, longer planting season, increased flexibility of planting schedule, and no planting check since the roots are protected in the soil plug and are planted with roots essentially undisturbed.

USDA Plant Hardiness Zone Map

Restrictions/regualtions of tree seedlings (live plant matter) for exportation into other countries can be costly and often prohibitive, therefore, we only ship to the states you see in the map below. These restrictions/regulations are in place to protect you and preserve your eco system.

Planting Instructions

Outdoor Planting

  • Choose a sunny location.
  • Prepare a hole 18" across and 12" deep.
  • Half fill with rich soil. Mix in some dry leaves or pine needles.
  • Remove seedling from protective casing. Center root plug.
  • Fill hole and pack soil firmly but gently.
  • Soak well with at least one gallon of water, (under watering is more harmful than over watering).
  • Water regularly when there is no rain.

    Indoor Planting
  • Choose a large container (approx. one gallon) with drainage holes in the bottom.
  • Follow outdoor planting instructions, watering well.
  • After initial watering, water only when dry.
  • In the Fall, place in a cool spot away from direct heat, to set dormancy until Spring.

What if I receive my tree seedling in the Fall? Your tree seedlings may be planted outdoors 4 weeks before a hard frost. Otherwise follow indoor planting suggestions and plant outdoors in the Spring.

What if I receive a tree seedling in the Winter months? We ship our tree seedlings year round! Both indoor and outdoor planting instructions are provided, so you may start the seedling indoors and transfer outdoors in the spring.
