Common Names
- Asian Lemon Bamboo
- Green Stripe Bamboo
- Painted Bamboo
- Striped Bamboo
Average Height and Diameter
-
Height: Typically reaches 15 to 25 feet (4.5 to 7.6 meters) at maturity.
-
Culm Diameter: Culms (canes) usually measure between 1 to 2 inches (2.5 to 5 centimeters) in diameter.
Growth Rate
Asian Lemon Bamboo exhibits a moderate to fast growth rate. As a clumping bamboo, it expands outward gradually, forming tight clusters without the invasive tendencies of running bamboo species. Under optimal conditions, new shoots can emerge and reach full height within a single growing season.
Sun Requirements
-
Optimal Exposure: Prefers full sun to partial shade.
-
Details: While it thrives best under full sun, providing at least 6 hours of direct sunlight daily, it can tolerate light shade, especially in hotter climates where some afternoon shade can prevent leaf scorching.
Cold Hardiness
-
USDA Hardiness Zones: 8b through 11.
-
Temperature Tolerance: Can withstand temperatures as low as 15°F (-9°C). In regions prone to colder temperatures, it's advisable to provide winter protection or consider container planting to move indoors during extreme cold.
Water Requirements
-
General Needs: Prefers consistently moist soil but is moderately drought-tolerant once established.
-
Watering Schedule:
-
Establishment Phase: Water deeply once or twice a week, ensuring the soil remains moist but not waterlogged.
-
Established Plants: Reduce frequency, watering during prolonged dry spells or when the top inch of soil feels dry.
-
-
Drainage: Ensure soil has good drainage to prevent root rot.
Detailed Fertilizing Guide
-
Frequency: Fertilize three times annually — in early spring, mid-summer, and early fall.
-
Type of Fertilizer:
-
Balanced Fertilizer: Use a balanced granular fertilizer with an N-P-K ratio of 10-10-10.
-
High Nitrogen Option: Alternatively, a high-nitrogen fertilizer (e.g., 20-5-10) can promote vigorous growth.
-
-
Application Steps:
-
Measurement: Follow manufacturer's guidelines, typically applying about 1 pound of fertilizer per 100 square feet.
-
Distribution: Evenly spread the fertilizer around the base, extending to the drip line (the area under the outer circumference of the plant's foliage).
-
Incorporation: Lightly rake the fertilizer into the topsoil to facilitate absorption.
-
Watering: Water thoroughly after application to activate the fertilizer and prevent root burn.
-
-
Organic Alternatives:
-
Compost: Incorporate well-rotted compost annually to enrich soil nutrients.
-
Manure: Aged manure can be an excellent organic fertilizer, applied similarly to granular options.
-
Planting Guide
-
Site Selection:
-
Sunlight: Choose a location receiving full sun to partial shade.
-
Space: Ensure ample space for the bamboo to spread, considering its mature size.
-
-
Soil Preparation:
-
Soil Type: Prefers loamy, well-draining soil rich in organic matter.
-
pH Level: Ideal soil pH ranges from 6.0 to 6.5.
-
-
Planting Steps:
-
Digging the Hole: Create a hole twice the width and the same depth as the root ball.
-
Positioning: Place the bamboo in the hole, ensuring the top of the root ball is level with or slightly above the surrounding soil.
-
Backfilling: Refill the hole with native soil mixed with compost.
-
Watering: Water thoroughly to settle the soil and eliminate air pockets.
-
-
Spacing:
-
Hedges or Screens: Plant 4 to 6 feet apart for a dense barrier.
-
Specimen Planting: Allow 8 to 10 feet between plants to showcase individual growth.
-
-
Mulching:
-
Application: Spread a 2-3 inch layer of organic mulch around the base, avoiding direct contact with culms.
-
Benefits: Mulch conserves moisture, regulates soil temperature, and suppresses weeds.
-
-
Containment Considerations:
- Barrier Installation: While clumping bamboos are less invasive, installing a root barrier can prevent unwanted spread in confined spaces.
USDA Zone
-
Optimal Zones: Best suited for USDA Hardiness Zones 8b to 11.
-
Zone Details:
-
Zone 8b: Average annual minimum temperatures of 15°F to 20°F (-9°C to -6°C).
-
Zone 11: Average annual minimum temperatures above 40°F (4.4°C).
