Longshadow Products are packaged in triple wall cartons attached to heavy duty pallets and shipped via common carrier tractor trailer trucks. Please read and follow the installation instructions provided with each item.

Most Longshadow Products are heavy and require professional installation and concrete footings appropriate for local conditions. Assembly requires experienced riggers, masons and equipment operators.

Follows all applicable ANSI and OSHA regulations.

Clean endless roundslings, a planter harness (or both), equipment and crew and clean hands are required for positioning pieces. Padding is required. Place the supplied drain mats felt side up over drain holes. Use high quality growing medium that drains well. Seal joints between bowls and bases. Drainage must be assured.

Product Care

The thick walls of Longshadow planters protect roots from heat and preserve moisture naturally. Good drainage is necessary for proper growing conditions. Wilting plants, soggy growing medium, staining, lime-bloom or mold on the outside of the planters are indications that drainage is blocked. If blockage is indicated, the growing medium must be removed and the drain flushed out.

Dry cast limestone is slightly porous and, in winter, can withstand freezing and thawing as long as good drainage is assured.
