Growing Supplies

Hand-picked for your Elderberry (Adams), with the extension research behind every recommendation.

Mulch / landscape fabric

Nearly every garden benefits from mulch for weed suppression, moisture conservation, and soil temperature moderation. For most home gardeners, quality organic mulch is the better buy over landscape fabric.

Our pick

Cleaned Wheat Straw Mulch (3 cu ft, ~20 lbs)

Thoroughly cleaned wheat straw at 3 cubic feet, marketed specifically for vegetable gardens rather than animal bedding or decoration. Better per-pound economics than the 1 cu ft option, with the same extension-recommended material. Strong sales volume (2K+ bought past month) supports product consistency.

Drip irrigation / soaker hose kit

Every gardener benefits from putting water at the root zone instead of on the leaves, because drip and soaker systems reduce foliar disease pressure by limiting leaf wetness and soil splash. A quality kit should include a backflow preventer, filter, pressure reducer, and UV-resistant tubing.

Clean straw mulch for berry rows

Penn State Extension says strawberry plantings require mulch for winter protection from cold and soil heaving and recommends about 4 inches of clean straw. It insulates shallow crowns and keeps fruiting zones cleaner.

Our pick

Cleaned Wheat Straw Mulch (3 cu ft, ~20 lbs)

Cleaned wheat straw at 3 cubic feet for larger strawberry plantings. Penn State recommends about 4 inches of clean straw for winter protection and notes that more exposed pyramid or raised-bed strawberry plantings benefit from 6 to 8 inches because the crowns are more exposed to cold air.
