Petunia: Finished Production Tips
Grow Time (From Rooted Cutting) A petunia in a quart container with one pinch per plant (ppp) takes five to six weeks of grow time. In a gallon container with one ppp, grow time is estimated at eight to nine weeks. Petunias in 12-inch baskets with four ppp take 10 to 11 weeks. Fertilizer Rate Apply 200 to 250 parts per million (ppm) nitrogen (N), using a calcium-magnesium formulation of a balanced fertilizer with low phosphorus (i.e. 13-2-13, 14-4-14 or 15-5-15 Cal-Mag) or a more acidic ammonium-containing fertilizer (i.e. 20-10-20 or 20-9-20) if keeping the pH low is a challenge. Electrical conductivity (EC) should be around 2.3 to 2.7 mS/cm (SME) with pH between 5.4 and 5.8. Supplemental iron-chelate (Sprint 138 or 330) as a drench (4 ounces/100 gallons) is recommended to avoid iron deficiency-related tip yellowing, especially under hot conditions and elevated pH (>6.0). Growing Media High-quality media with […]

Lobelia: Finished Production Tips
Grow Time (From Rooted Cutting) A lobelia in a quart container with one pinch per plant (ppp) takes six to seven weeks of grow time. In a gallon container with two ppp, grow time is estimated at eight to nine weeks. Lobelias in 12-inch baskets with four to five ppp take 10 to 11 weeks of grow time. PinchOne pinch, ideally done in propagation, is enough for small and midsize pots. Trailing types will benefit from a second pinch a few weeks after transplant. The second pinch is not as crucial for Techno Heat Upright types. When pinching, use excellent sanitation, including viricides like Virkon-S, RelyOn or Trisodium phosphate (TSP). Growing Media High quality media with good porosity is critical for best growth. Peat-based mixes, like Fafard 2 Mix or 1P Mix, or bark-based mixes, like Fafard 4P Mix or 3B Mix work well. Fertilizer Rate Apply200 parts per million […]

Verbena Propagation Tips
Upon Arrival Verbenas can be stored in a cooler down to 38 degrees F (5 degrees C) for up to 24 hours. Rooting Time Unrooted cuttings typically take about three to three and a half weeks to root in a 105-sized plug. These are fast rooters and are generally very easy to root. Growing Media High-porosity media like Fafard 1P Mix is ideal. Fertiss and Ellepot are also common. Keep pH at 5.8 – 6.2 and test media E.C. and pH at around three weeks after sticking and adjust as needed. Pinching Verbenas do need to be pinched. Try to leave at least 2 nodes below the pinch. Be sure to use good sanitation. Temperature Media temperatures of 72–74 degrees F are ideal. Once the cuttings are fully rooted, the temperatures can be lowered to control growth. Misting Spray CapSil at 2 to 4 ounces per 100 gallons one day […]
