How to determine when to fertilize roses
Today's focus is on introducing content about roses, specifically how to determine when to fertilize roses. This information will definitely help you, so let's learn together!
Roses not only require a lot of medication but also a significant amount of fertilizer, especially potted roses. So how do we determine when to fertilize roses? The following are some signs of nutrient deficiency in roses, which can also apply to other plants. It is recommended that gardeners do not wait until roses show signs of deficiency before fertilizing. Regularly applying a light amount of fertilizer will keep roses growing robustly.
Nitrogen is for leaves, phosphorus for buds, and potassium for branches. Nitrogen fertilizer is most important for roses, as it promotes growth and improves flower quality. Otherwise, it can lead to weak branches, yellow leaves, and slow growth of new shoots. However, excessive nitrogen in the soil can cause branches to grow excessively, resulting in fewer and deformed flowers.
Phosphorus fertilizer can promote the growth of rose roots, making the flowers more vibrant and the leaves thicker. Otherwise, the branches will be weak, and the flowers will droop.
Potassium fertilizer promotes the growth of new shoots in roses, increases the number of flowers, makes the buds plump, and enhances resistance. Additionally, it can increase the content of rose essential oil!
1: Deficiency name, Nitrogen: Plant form:矮小 (dwarf), few branches, leaf function impaired, leaves small and easy to fall, yellow-green, light green, or purple; stems thin and small, skin wrinkled, yellow-green, sometimes containing a lot of anthocyanin; roots grow weakly, with poor penetration; flowers wither early, mature and fall.
2: Deficiency name, Phosphorus: Slow growth, inhibited, few branches; leaves small, dark green, leaf stalks red-purple; stems thin, high in anthocyanin; roots poor growth, few fibrous roots; flowering period extended.
3: Deficiency name, Potassium:矮小,瘦弱 (dwarf and weak), poor resistance, easily infected by diseases and pests; spots on the top and edges of leaves, wrinkled, yellowed, scorched, curled into brown, with necrotic spots; stems prone to lodging, reduced supporting strength; poor root growth and water storage; low fruiting rate of flowers.
4: Deficiency name, Magnesium: Leaf veins yellow, sudden necrosis between leaf veins, leaf edges wrinkled.
5: Deficiency name, Calcium: Terminal buds often die, leaf tips and edges necrotic, tender leaves bent; roots die.
6: Deficiency name, Iron: Leaves yellow, larger leaves' veins remain green.
