Περιγραφή

Transplanting: Transplant directly into the finished container. Place the rooting media slightly below the level of media in the container. Make sure that the root ball is covered and that the cutting is situated in the center of the pot.

Moisture: Media should be allowed to dry between irrigations. Severe overwatering can lead to soft growth and fungus gnat issues, while severe under-watering and drought stress can result in bottom leaf yellowing, root tip abortion and longer crop times.

Fertilizer: 250 – 300 ppm nitrogen. Sangunas, like most petunias, are heavy feeders. Monitor EC levels and leach with clear water as needed to avoid fertilizer salt buildup. They grow best when using a blend of Cal-Mag (i.e. 15-5-15, 14- 4-14, etc.) and ammonium-containing (i.e. 20-10-20, 15-15-15, etc.) fertilizers. Cal-Mag types contain primarily nitrate nitrogen and help to promote toned growth, smaller leaves and media pH levels above 6. Ammonium nitrogen will encourage softer growth, larger leaves, higher media EC levels and lower media pH. A supplemental iron chelate (Sprint 330) or iron sulfate drench can be used at 2 – 4 ounces/100 gallon to correct iron deficiency (young leaf tip yellowing) when media pH levels have gotten well above SURFINIA are daylength sensitive and need relatively long days (short nights) to flower. Most varieties will come into flower naturally by early to mid April. Atomic Blue, Purple and Rose Vein tend to be later flowering and more daylength sensitive than most others in the line.

Media: pH: 5.4 – 5.8. Keep pH down in the low to mid 5s to avoid iron deficiency and tip yellowing.

Media EC: 2.3 – 2.7 mS/cm (in an SME, saturated media extract).

Temperature: 65° – 75°F (18° – 24°C) day and 50° – 60°F (10° – 15°C) night. Cooler temperatures can be used to help control growth, but plants will be delayed in flower.
