Dianthus F1 Dianthus
A new F1 hybrid interspecific Dianthus that holds its flowers clustered in an ‘umbrella’ on top of the foliage. More than 7 days earlier than ‘Ideal’ & ‘Telstar’ and with a superb natural dwarf habit. An excellent product for packs or small pots and with great flower presentation at point of sale.

easy grow guide dianthus IQ (F1 Dianthus chinensis x barbatus)
Plug Production: 288 plugs
Use a well-drained, disease-free, peat based plug medium with pH 5.8-6.2, EC <1 mmhos. Cover lightly with vermiculite to help maintain moisture levels. Media temperature should be 64-70°F (18-21°C) at sowing. Maintain good media moisture until emergence (days 1-5). Once seedlings have emerged, media moisture can be reduced slightly, but avoid wilting! Light is not required for germination, but light levels as low as 100 f.c. can be beneficial. During stage 2 you can begin to fertilize with 50-100 ppm N but maintain EC levels <1 mmhos as Dianthus are sensitive to high salt levels. Media moisture can be reduced further between irrigations to improve rooting, but avoid wilting! Temperatures can be reduced to 61-65°F (16-18°C). Light levels can be increased to <3000 f.c. Fertilize as needed with 100-125 ppm N, maintaining media pH 5.8-6.2 and EC <1mmhos. Maintain media moisture levels as per stage 3. Fertilize as needed with 125-150 ppm N from a calcium based fertilizer, maintaining media pH 5.8-6.2 and EC 1-1.25 mmhos. Light levels can be increased to 3500-4500 f.c. Temperatures can be lowered to 57-61°F (14-16°C) for toning. IQ is a facultative long day plant so increasing the day length up to 14 hours will speed up flowering. Good light levels, moisture management and cooler temperatures all help with growth control. Sprays of Bonzi (3-5 ppm), Cycocel (750-1000ppm) or Sumagic (3-5 ppm) can also be used to control growth. Weather conditions and cultural practices directly affect how much growth regulator to use, so it is recommended that you run your own trials.

Use a well-drained, disease free, peat-based growing media with a pH 5.8-6.2, EC 1.25- 1.75mmhos. Keep day temperatures at 61-68°F (16-20°C) but night temperatures can be lowered to 54- 59°F (12-15°C). Exposing the plants to a negative DIF will prevent stem elongation.
Media:
Temperatures:
Keep light levels up to 3500-4500 f.c.
Light:
Practice a good wet/dry moisture cycle avoiding wilting.
Irrigation:
Fertilize every other irrigation with 125-150 ppm N from a calcium based fertiliser. Keep media pH at 5.8-6.2 and EC no higher than 1.5mmhos. Good light levels, moisture management and cooler temperatures all help with growth control. Exposing the plants to a negative DIF or ‘ morning drop ’ is also effective on Dianthus for controlling stem elongation. Further growth control can be achieved with 1-2 sprays of Bonzi (15-20 ppm) or B-Nine (2500-3000ppm), or until desired height has been achieved; although too many applications may delay flowering. It is best to run your own trials to avoid overdosing, as environmental conditions and cultural practices can affect results.
