Thoroughly water once or twice a week. Sunflowers have deep roots and can be irrigated infrequently or lightly
Adjust your watering frequency on particularly hot or cloudy days. Your sunflowers should bloom in mid summer or late summer, about two to three months after planting
Root protection. Once the seedlings are tall enough and the root protection measures do not break them, a layer of straw or other root protection can be placed on the soil to moisturize and prevent weed growth. Remember to top up the mulch after the heavy rain
If planting sunflowers is for harvesting seeds or decorating flowers, when the seedlings grow to half a meter high, a layer of 4-centimeter thick decomposed farmyard manure or compost can be laid
If necessary, tie it to a pole. If you live in windy areas or if your flower diameter is not strong enough, consider tying the plant with bamboo or wooden poles to help it bear the weight of the plant
