Petunia - Propagation Tips • URC arrival:

• Priority 3 – can be stored in cooler if needed for up to 24 hours

• Rooting Time: 3-3.5 weeks in 105 size plug (fast rooters)

• Media: High porosity mix like Fafard 1P; Fertiss® and EllePot® are also common

• Pinch in Prop: No, unless doing a large jumbo plug

• Temperature: 72 F ideal in media (can tone at lower temps to help control growth)

• Misting:

• Capsil® spray (2-4 oz/100 gal) 1 day after sticking to reduce wilting early on

• Not as much needed as most crops – 6-7 days of misting generally sufficient

• Reduce mist quickly; over misting can cause purpling, chlorosis, tip abortion

• Fertilizer: 100-150 ppm N after roots form using Cal-Mag formulation

• Early feeding critical; maintain sufficient micronutrient (Fe, Mn, B, etc.) levels

• Supplemental Fe-chelate (Sprint® 138 or 330) drench (2 oz/100 gal)

• PGR:

• B-Nine® 2500 ppm spray or Sumagic® 3-5 ppm spray

• Trial Florel® (350 ppm) or Florel® (350 ppm) + B-Nine® (1250 ppm) combo

• URC arrival: Fungicide spray for Botrytis control at day 2

Effects of over-misting in propagation• Some petunia varieties can be

worse than others


6

• Grow time (from RC):

• 5-6 wks – Qt; 8-9 wks – Gal (1 ppp); 10-11 wks – 12-inch Baskets (4 ppp)

• Fertilizer Rate: 250 ppm N and higher if needed

• Supplemental iron if needed (Sprint® 330 or 138 at 2-4 oz/100 gal)

• EC: 2.3-2.7 mS/cm (SME); Media pH: 5.4-5.8

• Media: Fafard #2 or 1P (peat-based) or Fafard 4P or 3B (bark-based)

• Temperature: 65-75 F Day, 55-60 F Night (can go colder, but will delay flowering)

• Pinch: 1 pinch is generally all that is needed

• Extra-large pots/baskets can be pinched twice

• Light: LD plants – provide night-interruption on crops sold before April 1

• Not as LD sensitive as calibrachoa, but some varieties are naturally later than others

• PGR:

• B-Nine® 2500-3500 ppm spray or Sumagic® 15-20 ppm spray

• Bonzi® drenches at 1-3 ppm work nicely mid season (Picnic™ – 1 ppm; Whispers™, Sanguna® – 2-3 ppm)

• Some growers use Florel® early on baskets at 350-500 ppm to enhance branching

• Insects and Diseases: Thrips, budworm, leafminer, TMV, INSV

• Use a viricide (Virkon®S, RelyOn™, Trisodium phosphate [TSP]) when pinching
