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.
PLANTING
Longshadow dry cast limestone is slightly porous. This porosity reduces possible damage from freeze-thaw cycles. The supplied soil filter square should be placed, felt side up, over the drainhole. Use well draining, high quality, loose growing medium.
SUMMER
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, the drainage must be flushed out, assured and maintained.
WINTER
Good drainage is required to prevent accumulation of water inside planters. Water expands as it freezes and could cause damage. Many owners use the growing medium to anchor a display of evergreen boughs and berries. Longshadow dry cast limestone planters can withstand freeze-thaw cycles as long as drainage is assured.
SEALING
It is not necessary or desirable to seal the interior of Longshadow planters and voids the Longshadow warranty.
