Controlled germination Covered or plain Sowing instructions: Method: 1 seed per plug. For plug production a soil with pH 5,5 to 6,5 is used. Cover the seeds lightly, e.g. with Vermiculite (grade 2), to prevent drying out. Gerbera can germinate in dark as well as in light circumstances. Time: in principle possible to sow year-round. To overcome the dark winter period, growers in North Western European countries usually do not sow from week 32 to week 40. Planning of a crop is very simple: sow 15 weeks before planned sales period. Temperature: 18-20°C (64-68°F) during germination. Maintain a high humidity in the sowing department. Use a preventive treatment e.g. Rovral half concentration (active ingredient is iprodione) against damping-off diseases directly after sowing. Keep the seed boxes moist during germination. Germination time: 4-7 days after sowing. One week after sowing, open sides of the germination chamber. Day 1 Day 3 Day 5 Day 7 Day 11 Day 13

Seedling production 13 days after sowing SowEasy® seeds

Growing on: Transplanting/potting: remove the seedlings from the germination chamber, end of the second week. Grow on at 20°C until 4-05 weeks after sowing. Then, sort the seedlings (if necessary) Potting/soil: into two sizes and pot them in a light and well-airated medium . Pot size: potting soil into 12 cm. pots (pH 5,5-6). Irrigation: overhead watering is possible until the flowerbuds appear, but watering directly into pot or grow with ebb/flow floors is preferred. Density: after potting the density is approx. 80pl/m² for 3-4 weeks; by then the plants need to be spaced to 20-25 pl/m² until end of culture. Culture temperature: best results with 19-19°C or 19-17°. In darker periods D/N temperatures can be reversed to keep stem length somewhat shorter. Diseases/pests Should any disease or pest (mildew, white fly, thrips) emerge, treatment with pesticides known from the cut flower culture can be applied Fertilization: Gerbera requires relatively high fertilization gifs. This is light and temperature dependent. For general use, a list with target values is taken up into this cultural info Light: Gerbera likes to be grown under high light conditions. During the darker period of the year, additional lighting can be applied. Croptime: depending on the sowing date, the available light and the required pot/plan ratio, the culture will take approx. 14 weeks from sowing to 50% flowering. The second 50% can be reaped in 10-14 days

General advice: special wrapping sleeves are available in most countries. Do not use plastic. Paper or polypropylene is preferred.

Humidity strategy It is very well possible to sow Gerbera without covering the seed. Keep the climate in the germination chamber as humid as possible. First day after sowing, mist + propamocarb up to 25 liters of water per 100 m². Plug and seed must be saturated. Use water with EC-0. Keep this climate for 6-7 days. From day 8: start lowering the RH towards 80% by opening the germination beds. From day 14: remove cover (plastic); reduce watering. From day 21: remove fleece cover; watering (overhead) if plants need it. (In this stage plants need approx. 1/3 of the amount of water of the start. Mistakes made in this part of the culture of Gerbera are: Mist: drip size to large -> cotyledon damage. Water is too cold: hard and brittle plants. No propamocarb: plants wilt and die off. Old plastic cover or infected boxes: plants wilt and die off. Unperforated cover: lack of oxygen -> plants die. From day 28: start watering and add a little fertilizer (EX 0.8). This week sorting starts also. If one grows in plug trays, sorting is easy: sort in 2 or 3 sizes. Size 1 and 2 can grow in the plug tray, only half the density, until potting 2-3 weeks later. Size 3 needs another 1-2 weeks to grow into shape. During harvest of the flowering plants, there is hardly any difference between the three sizes.

*Dr. Koranski's Moisture Management Criteria* Saturated -5 Water is easily observed. Press finger on cell Wet -4 Water is not easily observed. When media is lightly touched, there is very little movement from top to bottom. Moist -3 Media is black but not glistening. To the touch, there is water, but virtually no water movement. Medium -2 The media has changed colour from a dark black to a medium brown. There is no water movement. Dry -1 The media has change colour to a very light brown. Watch out for algae crust where applicable.   Relative Light Temp.
