5 components of success with Petunia
No cover.
Diseases
pH < 5.8!
Feed your plants.
Boron!

Not cover!
• Light requires for Petunia germination. • Seeds should be kept on the surface. • Provide light in the germination chamber. • Fine layer of vermiculite can be beneficial for pelleted seeds only.
Provide deepening.

Substrate. Keep pH 5.5 ― 5.8
• Porous substrate (30% of perlite). • Suitable substrate components:
cocopeat peatmoss wood fiber peat
Wood fiber based.
• Rinse cocopeat well. • Airy agent: perlite > sand > zeolite > vermiculite. • Sift the substrate to obtain a uniform particle size 0―5 mm. • pH range: 5.5―5.8 2 3 4 5 6 7 8

Substrate. Keep pH 5.5 ― 5.8
• Critical factors affecting pH: initial pH of substrate,
high sodium (Na) concentration, excess of calcium (Ca) in the water and substrate.

Young plant stage. Feed your plants.
• Substrate EC (SME): 0.9―1.3 mS/cm • Provide plant with 75―125 ppm of nitrogen. • Do not use too much phosphorus! • Suitable NPK rate: 15-5-15, 15-3-15 15-5-10, 18-5-15, 17-5-17. • Give fertilizers with every watering .
Proper NPK rate
• Do not use 15 - 15 - 15 or 17 - 17 - 17 ! • Do not use ureum (NH2)2CO! • Do not use clean water (without fertilizers). • Do not use dry fertilizers
Feed your plants
Public
Vegetation. Feed your plants well. • Translate 75―125 ppm of nitrogen to gram of NPK. • Do not use too much phosphorus! • Suitable NPK rate: 15-5-15, 15-3-15 15-5-10, 18-5-15, 17-5-17. How to convert ppm of N into mass of fertilizers? The range of nitrogen recommended in the growing tips is 75―125 ppm. Let’s start with 125 ppm. 125 ppm means 125 mg should be added into 1 l of water. There is available fertilizer with NPK rate like 15–5–17 % on the farm. NPK rate like 15–5–17 contains 15 mg of nitrogen in 100 mg. Thus, to get 125 mg of nitrogen we need to take: (125 x 100)/15 = 833,3* mg of fertilizer. * 833,3 (0.5 g) provides EC in the water about 1,2―1,4 mSm/cm
Proper NPK rate
Feed your plants.
! Don’t forget to provide Ca and Mg every 5 th or 6 th watering!

Diseases. Bio protection. Add Trichoderma-base or bacterial-base chemical into substrate mixture (Gliocladium catenulaturm, Bacillus subtilis, Bacillus amylolquefaciens , Streptomyces sp. K 61, Streptomyces lydicus strain WYEC 108, * Trichoderma harzianum, Trichoderma virens, Trichoderma asperellum, Trichoderma gamsii…) * Chemical on the base of bacteria can be combined with fungicides as well. Can be used as prophylactic.
