Feeds Growth, Coverage & Bloom Equally

Climbers need nitrogen for vine extension, phosphorus for flower production, and potassium for stem strength against wind and weight. 10-10-10 delivers all three in balance.

🌸

Supports Flowering Vines

10% phosphorus maintains bloom production in clematis, wisteria, honeysuckle, and jasmine. Consistent feeding through the season extends the bloom window.

💪

Potassium for Stem Strength

Long climbing stems face wind, rain, and the weight of their own foliage. 10% potassium strengthens cell walls for stems that hold up under stress without snapping.

📏

Per-Plant Dosing

½ cup for young or small vines, up to 2 cups for large established climbers like mature wisteria. Simple per-plant application at the base.

📦

6–22 Plants Per Bag

One 5 lb bag feeds 6 large established climbers or up to 22 young vines per application. Scale to your trellis, arbor, or fence line.

📅

Every 4–6 Weeks

Actively growing climbers are hungry plants. Feed every 4–6 weeks during the growing season to sustain the rapid stem extension and leaf production they're known for.

✅

All Climber & Vine Species

Clematis, wisteria, climbing hydrangea, trumpet vine, honeysuckle, jasmine, passion vine, Virginia creeper, Boston ivy, grapevine — every climbing plant thrives on balanced feeding.
