Planting Instructions (From a Bulb into the Ground)

1. Choose the Location

• Select a warm location with rich, fertile, moisture-retentive soil.
• Ideal for tropical gardens, pond edges, rain gardens, and large landscape beds.

2. Prepare the Soil

• Loosen soil 10–12 inches deep.
• Incorporate compost or well-aged organic matter to improve fertility and moisture retention.

3. Plant the Bulb

• Dig a hole approximately 4–6 inches deep.
• Place the bulb with the growing point facing upward.
• Cover with soil and gently firm the area.

4. Water Thoroughly

• Water deeply after planting.
• Keep soil consistently moist but not waterlogged throughout the growing season.

5. Mulch

• Apply 2–3 inches of mulch around the planting area to retain moisture and suppress weeds.

6. Spacing

• Space bulbs 3–5 feet apart to accommodate mature growth.

Seasonal Care & Maintenance

• Water regularly, especially during hot summer weather.
• Fertilize monthly during active growth to encourage large foliage production.
• Remove damaged or yellowing leaves as needed.
• Maintain evenly moist soil throughout the growing season.

Overwintering (Zones Below 8)

1. Allow foliage to remain until the first light frost.
2. Cut foliage back to a few inches above the bulb.
3. Carefully dig and lift the bulb before hard freezes occur.
4. Allow bulbs to dry for several days in a warm, shaded location.
5. Store in dry peat moss, vermiculite, or sawdust in a cool, frost-free location between 45–60°F.
6. Replant outdoors after danger of frost has passed in spring.
