GAILLARDIA grfl. MESA YELLOW

Availability: In stock

The first F1 gaillardia from seed, award-winning Mesa Yellow arrived in 2010 to deliver a more uniform habit with more flowers than other varieties. Now exciting new Bright Bicolour debuts with the same outstanding performance! This first year-flowering perennial is suitable for both annual and traditional perennial production. The strong, early-flowering and well-branched plants fill gallon containers quickly while maintaining a controlled height without “flopping” over. The uniform habit and flowering time make it easy to schedule and ship. Very drought tolerant once established, Mesa shows intense, non-fading colour all season on upright, well-branched plants that perform well in landscapes and mixed containers. Fits well into 4-in./10-cm to gallon programs.

GrowerFacts

Gaillardia Mesa
(Gaillardia x grandiflora)

Germination

Media
Use a well-drained, disease-free, soilless media with a pH of 5.8 to 6.2 and a medium initial nutrient charge (EC 0.75 mmhos/cm).

Sowing
Sow seed in 288 or larger plug tray. In Europe, 264- cell trays can be used. Covering seed with vermiculite is recommended.

Stage 1 – Germination takes 4 to 5 days. Soil temperature: 68 to 73°F (20 to 23°C)

Light: Optional.

Moisture: Keep soil wet (level 4) during Stage 1.

Humidity: Maintain 95%+ relative humidity (RH) until radicles emerge.

Plug Production

Key flowering facts:

•  Mesa Gaillardia is a first year-flowering perennial.
•  Photoperiod response: a facultative long-day plant and requires 14 hours or longer daylength for uniform and faster flowering.
•  Vernalization: not required but beneficial as flowering will occur 4 to 5 weeks earlier following a minimum of 10 weeks cold treatment.
•  Flower timing:
❍     Sown in January as Spring production, will flower naturally in late May to early June.
❍     Sown from July to early September for overwinter production, will flower late April of the following year.

Plug Production

Media
Use a well-drained, disease-free, soilless media with a pH of 5.8 to 6.2 and a medium initial nutrient charge (EC 0.75 mmhos/cm).


Sowing
Sow seed in 288 or larger plug tray. In Europe, 264- cell trays can be used. Covering seed with vermiculite is recommended.

Stage 1 – Germination takes 4 to 5 days. Soil temperature: 68 to 73°F (20 to 23°C) Light: Optional.
Moisture: Keep soil wet (level 4) during Stage 1.

Humidity: Maintain 95%+ relative humidity (RH) until radicles emerge.


Stage 2
Soil temperature: 68 to 73°F (20 to 23°C)

Light: Up to 2,500 f.c. (26,900 Lux)

Moisture: Reduce soil moisture slightly (level 3 to 4)
to allow the roots to penetrate into the media.

Fertilizer: Apply fertilizer at rate 1 (less than 100 ppm N/less than 0.7 mS/cm EC) from nitrate-form fertilizers with low phosphorous.


Stage 3
Soil temperature: 65 to 67°F (15 to 19°C)

Light: Up to 2,500 f.c. (26,900 Lux)

Moisture: Allow media to dry further until the surface becomes light brown (level 2) before watering. Keep the moisture to wet-dry cycle (moisture level 4 to 2).

Fertilizer: Increase fertilizer to rate 2 (100 to 175 ppm N/0.7 to 1.2 mS/cm EC). If growth is slow, apply a balanced ammonium and nitrate-form fertilizer with every other fertilization. Maintain medium pH of 5.8 to 6.2 and EC between 1.0 and 1.5 mS/cm (1:2 extraction).

Growth Regulators: Generally not needed. If necessary, B-Nine/Alar (daminozide) 2,500 ppm (3.0 g/l 85% formulation or 4.0 g/l of 64% formulation) can be applied at

Stage 3.

In northern European conditions: Use Alar/B-Nine
1,300 ppm (1.5 g/l 85% formulation or 2.0 g/l of 64%
formulation).

Stage 4
Soil temperature: 59 to 64°F (15 to 18°C)

Light: Up to 5,000 f.c. (53,800 Lux) if temperature can be controlled.

Moisture: Same as Stage 3.

Fertilizer: Same as Stage 3.

Growing On to Finish

Container Size
4.5-in. (11-cm) square or quart pots: 1 plant per pot

6-in. (15-cm) or gallon (18-cm) pots: 1 plant per pot

Media
Use a well-drained, disease-free, soilless media with a pH of 5.5 to 6.2 and a medium initial nutrient charge (EC 0.75 mmhos/cm).

Temperature
Nights: 50 to 61°F (10 to 16°C)

Days: 59 to 70°F (15 to 21°C)
Mesa Gaillardia can be grown at lower temperatures (frost-free cold frame/poly house in Spring), however crop times will increase.

Light
Maintain light levels as high as possible while maintain moderate temperature.

Photoperiod
Mesa Gaillardia is a facultative long-day plant and requires 14 hours or longer daylength for uniform and faster flowering

Irrigation
Maintain media moisture. Plants can dry out quickly when they are large. Water thoroughly when irrigation is needed.

Fertilizer
Apply fertilizer at rate 3 (175 to 225 ppm N/1.2 to 1.5 mS/cm) using predominately nitrate-form fertilizer with low phosphorus and high potassium. Maintain the media EC at 1.5 to 2.0 mS/cm and pH at 6.0 to 6.5.

For constant fertilizer program, can apply fertilizer at rate 2 (100 to 175 ppm N or 0.7 to 1.2 mS/cm) while
maintaining the above recommended EC and pH ranges.

Growth Regulators
PGRs are not necessary if grown under cooler temperatures. If necessary, B-Nine/Alar (daminozide) 5,000 ppm (6.0 g/l 85% formulation or 8.0 g/l of 64% formulation) is good for plant size control.

In northern Europe conditions: 3,200 ppm Alar (3.8 g/l 85% formulation or 5.0 g/l of 64% formulation) works well.

Pinching
Pinching is not needed.

Spacing
Space plants when foliage is touching.

Crop Scheduling
Sow to transplant (288 cell plug): 5 to 6 weeks

Transplant to flower: 11 to 13 weeks

Total crop time: 16 to 18 weeks. Generally, Mesa Bright Bicolour flowers about 1 to 2 weeks faster than Mesa Yellow dependent on daylength conditions. The longer daylength (longer than 14 hours) they are
grown under, the bigger the difference in flower timing.

Note: The total crop time of about 16 to 18 weeks is based on Spring production under night temperatures of about 50 to 61°F (10 to 16°C) and day temperatures of about 59 to 70°F (15 to 21°C) with natural daylength. Crop time will be shorter under warmer temperature and long day conditions, or longer under cooler and short day conditions.

Spring Production: Sow in January for natural flowering in later May to early June.

Overwinter Production: Sow in July to early September for natural flowering late April of the following year.

Common Problems
Insect: Watch for fungus gnat larva and thrips.

Disease: INSV, white smut, powdery mildew.

Germination: Occasionally there are albino seedlings which will not develop into viable plants. Frequency can vary up to 9%
