Why do different lots of New Guinea Impatiens often flower
differently?

Pot size does not affect time to flower.
It is not pot size

Oro Farms Stock Management.
• We assure a stage 0 cutting with the Oro Farms technique. To avoid this problem
• A stage 0 cutting is essential for uniform flowering.

Variable cuttings yield variable flowering dates
Stage 0.5
![Page 12: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/12.jpg)
Without our Technique flowering will be un-uniform and it will be like
picking tomatoes.
![Page 13: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/13.jpg)
Optimized production of NGI in 4” pots
• Concepts:– Uniform flowering– Predictable flowering on date desired– Limited time (5 weeks) for plant in finish
container
![Page 14: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/14.jpg)
Recommended production schedule
• Recommended Liner size and age for 4 inch to 5 inch production is a 7 week old 50 cell liner with a low soil volume.
• Recommended Liner size and age of liner for Hanging Basket is a 4 week old 128 cell liner.
• The sooner you plant to finish container the larger the finished product will be.
![Page 15: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/15.jpg)
Optimized production of NGI in 4” pots
Small cuttings with small leaves helps control plants size in the Liner.
![Page 16: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/16.jpg)

Large leaves create problems in propagation
![Page 18: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/18.jpg)

Optimized production of NGI in 4” pots
• Small cuttings with small leaves help control plants size in the plug
• Flower buds in cuttings create production problems
![Page 20: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/20.jpg)
New Guinea Impatiens plugs with flower buds

New Guinea Impatiens cuttings with flower buds at stick
resulting in plants flowering before adequate vegetative size
![Page 22: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/22.jpg)
New Guinea Impatiens cutting that was reproductive on
arrival makes for a poorly branched plant
![Page 23: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/23.jpg)
Small vegetative cuttings with small leaves eliminate these
problems
![Page 24: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/24.jpg)
New Guineas Liners looking super
![Page 25: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/25.jpg)
Uniform vegetative cuttings, proper Liner production
(nutrition and PGR) allows uniform and predictable
flowering.
![Page 26: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/26.jpg)
New Guineas starting to flower
![Page 27: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/27.jpg)
Keys to 4” NGI production
• Appropriate genetics – moderate leaf size is best
• Stage 0 cutting
• Uniform small cutting
• Appropriate Liner soil volume
• Appropriate nutrition and PGR application
• Temperature control
![Page 28: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/28.jpg)
Once a cutting initiates a flower, temperature is the
primary factor driving time to flower, but relative humidity is
also important because it affects plant temperature.
![Page 29: New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production.](https://reader036.fdocuments.net/reader036/viewer/2022062407/56649db45503460f94aa4f29/html5/thumbnails/29.jpg)
Other considerations
• Relative humidity at night is important.
• Low humidity will cause the plant to cool its self and will not realize the correct temperature. 80% humidity at night is best.
• Liner soil volume is important for plant size control
