It can be used not only as a base fertilizer, but also as a topdressing fertilizer around the plants. It takes effect immediately after application and lasts for 2 to 3 months (3 peaks mixed). It is a slow-release fertilizer, a mixture of humic acid, which makes it easier for plants to absorb fertilizer, improves soil water retention and aeration, and revitalizes the soil, while also having high-quality vegetable organic matter. It uses "release control technology" to adjust the amount of fertilizer according to temperature changes. During warm growth and vigorous growth periods, the fertilizer components are quickly leached, and on the contrary, during cool weather and slow growth periods, the fertilizer components are slowly leached. It provides nutrients efficiently and wastelessly during the growth process of plants, making roses grow luxuriantly and bloom beautifully.
