How to Sow and Plant
+
Sow giant sunflower seeds outdoors from mid-April to the end of May directly in open ground or a moist seedbed. Plant seeds about 1/2 cm deep and gently press the soil to ensure good contact. Once seedlings emerge, thin or transplant them to maintain a spacing of 50 x 50 cm for optimal growth. This allows each plant ample room to develop its tall, sturdy stem and large flower head. Choose a sunny location with well-drained soil for the best planting results and a spectacular sunflower display.
Giant sunflowers thrive best in full sunlight, where they can develop their impressive height of over 3 meters. Ensure soil is well-drained and moderately fertile for optimal growth. Regular watering supports sturdy stems and vibrant blooms, but avoid waterlogging. Provide enough space, about 50 x 50 cm between plants, to allow proper air circulation and root development. Protect young plants from strong winds as their tall stems can be vulnerable. Harvest mature seeds for bird feeding or drying, encouraging natural reseeding and a continuous display of these striking yellow giants year after year.
For optimal growth, sow giant sunflower seeds directly outdoors from mid-April to May in well-drained, moist soil. Plant seeds about 1/2 cm deep and space seedlings 50 x 50 cm apart to allow ample room for these towering sunflowers, which can exceed 3 meters in height. Ensure they receive full sunlight daily and water regularly to support sturdy stems and vibrant blooms.
