Blue Grape Hyacinth Super Sack

Grape Hyacinth bulbs are planted in fall so they can chill over winter and bloom in mid spring. Open your package right away and let the bulbs breathe in a cool, dry spot until planting day.

Planting

1. Pick your spot. Choose a site with full sun to part shade that avoids intense afternoon sun, and make sure water never puddles there.
2. Loosen the soil. Work the top 6 to 8 inches until it crumbles, mixing in compost if your soil is heavy clay.
3. Set the depth. Plant bulbs 3 to 4 inches deep with the pointed tip facing up and the flat, rooty base down.
4. Space them close. Keep bulbs 2 to 3 inches apart and plant in groups of 15 or more for the best drift effect.
5. Backfill and water. Cover, firm the soil gently, and water once to settle everything in.

Watering

• After planting. One good soaking is enough; fall and winter moisture usually handles the rest.
• During growth. Keep soil lightly moist while leaves and flowers are active in spring.
• After bloom. Ease off water once foliage yellows, since dormant bulbs prefer drier soil.

Feeding

• At planting. Mix a balanced bulb fertilizer or bone meal into the planting hole.
• Each spring. Scatter a light feeding of balanced fertilizer as shoots emerge to fuel next year's flowers.

Aftercare

• Leave the leaves. Let foliage die back naturally so the bulbs can recharge; grape hyacinth often pushes new leaves again in fall, which is normal.
• Mulch lightly. A 1 to 2 inch layer of mulch keeps soil temperatures steady without smothering the small shoots.
• Divide as needed. Every few years, lift and separate crowded clumps after the foliage fades and replant elsewhere.

Containers

• Use a draining pot. Fill with well-drained potting mix and plant bulbs 3 inches deep, shoulder to shoulder.
• Chill through winter. Leave pots outdoors in an unheated, sheltered spot so bulbs get their cold period.

When should I plant these bulbs?

Plant in fall, ideally after soil temperatures cool but several weeks before the ground freezes. The bulbs need winter chilling to bloom in mid spring.

Will grape hyacinths spread on their own?

Yes. Muscari armeniacum is an excellent naturalizer that multiplies by offsets and seed, so plantings thicken and widen year after year.

Can they handle shade?

They do well in sun to part shade and are a great choice for shady areas or spots protected from intense afternoon sun. Deep, all-day shade will reduce flowering.

Are grape hyacinths deer and rabbit resistant?

They are generally left alone by deer and rabbits, and squirrels rarely dig them, which makes them a reliable choice in browsed gardens.

Are they toxic to pets?

The bulbs and foliage can cause stomach upset if eaten, so plant where curious pets are unlikely to dig and keep unplanted bulbs out of reach.

What comes in the Super Sack?

You receive 50 dormant, ready-to-plant bulbs sized 8-9 cm. That is enough to cover roughly 8 to 10 square feet at 2 to 3 inch spacing.
