  • Patent number: 5813170
    Abstract: An improved direct seeding shelter is disclosed. The shelter comprises a base, a side wall, a top including a cylindrical portion and a displaceable cover that is operable, in a first position, to prevent a seed from passing from the interior of the shelter to the exterior of the shelter, through the shelter top. The shelter can be pre-seeded by inverting the shelter, positioning the displaceable cover in the first position, depositing at least one seed into the shelter and into the cylindrical portion, positioning a seed retainer in the cylindrical portion so that the retainer is frictionally engaged therein and is operable with the displaceable cover to define a seed pocket. Direct or spot seeding with the pre-seeded shelter is easily carried out by setting the shelter in the soil and depressing the at least one flap to dislodge the seed retainer. The dislodged seed and the seed retainer fall by gravity to the seeding spot.

  • Patent number: 5345711
    Abstract: A treeshelter system comprising a unitary treeshelter with integral staking means is disclosed. The treeshelter system may include treeshelter extenders with a lower edge having connector means which cooperate and connect with connector means provided on the upper edge of a unitary treeshelter or on the top edge of another treeshelter extender. The unitary treeshelter comprises a hollow tube, preferably in the form of a truncated cone, open at both ends, and formed of polymeric material. The tube comprises integral staking means consisting of a plurality of rods secured to and supported in a like number of bosses formed integrally with the tube, and spaced substantially evenly around the lower edge of the tube. A unitary treeshelter according to the invention is installed in a single step by positioning it over a seedling and pressing downwardly until the lower end of it is flush with the ground and the rods are securely embedded in the ground.
