FERTILIZATION & IRRIGATION GUIDELINES Summerinas are fast growing plants and therefore require a larger amount of fertilizer than most plants. • We recommend starting with 4 KG Osmocote per m³. Use a 5-6 month Osmocote with high Potassium (K).
• Add 200 gram Micromax trace element to the soil in addition to the normal starter mix.
• Once the plants are rooted in the pot, raise the EC level in the soil to 1.5 using liquid 27-15-12 feed. If you cannot add extra liquid fertilizer, then the best option is using a 5-6 month Osmocote with high K. • Summerinas need a good amount of water during the growing season. Overhead irrigation and drip irrigation both work well.With overhead irrigation, try to water early in the morning.You might see some leaf burning from water droplets during very hot days and watering in the evening can lead to disease issues, as plant foliage will remain wet into the night.With drip irrigation, you can water at any time of day.
