🍃Fertilization

Burning Hearts False Sunflower does not have strict requirements for fertilizer and water. Generally, when it grows well, only appropriate nitrogen, phosphorus, and potassium fertilizers need to be applied according to the actual situation, combined with watering, following the principle of seeing dry and wet, so that the flowers can be more beautiful. Medium fertilizer requirement, apply a certain concentration of nitrogen and potassium balanced fertilizer (N: K ratio of 1:1.5) every week to avoid high ammonium and nitrogen levels. To prevent magnesium and iron deficiency, magnesium sulfide with a concentration of 0.05% can be sprayed 1-2 times, and iron chelates can be sprayed 1-2 times. When planting plants, fertilize once a month with a small amount of nitrogen, phosphorus, and potassium fertilizer as the main fertilizer. Apply more phosphorus and potassium fertilizer before flowering, and do not use nitrogen fertilizer at this time.

🌞Illumination

I prefer a sunny environment, but my sensitivity to sunlight is not strong. Whether it is sunny or weak, the bright effect of flowers will not be affected. Long sunshine (14-16 hours) is beneficial for flower bud differentiation, while insufficient sunlight can lead to plant elongation. Maintaining sufficient light is beneficial for the growth of thick stems and can improve flowering quality. But in summer, there is strong sunlight, so it is advisable to shade and cool down appropriately to avoid high temperatures affecting the normal growth of plants. Especially during the flowering period, it is important to pay attention to proper shading to maintain the beauty of the flowers.

💦Trim

When the leaves are too dense, the old and diseased leaves on the outer layer of the plant should be removed in a timely manner to improve its lighting and ventilation conditions, thereby reducing the probability of disease and pest occurrence and unnecessary consumption of nutrients. It is also more conducive to the development and growth of new leaves and flower buds, improving their quality. After the flowering period of the Burning Hearts False Sunflower, some residual branches and rotten leaves should be promptly pruned to promote the growth of lateral branches and prolong the flowering period. If cut flowers are needed, the top buds can be removed appropriately to extend their flowering period. When the plant grows to over 1 meter, it is prone to lodging due to its height. It is necessary to promptly set up scaffolding for tying to prevent the plant strips from being broken by wind.

🌡️Temperature

Burning Hearts False Sunflower can adapt to the environment of Hardness Zone 5 to 9.

🪧Soil

Do not excessively dry or water, as excessive drying can lead to burnt edges and yellowing of the leaves. Be careful to avoid poor drainage and prevent root waterlogging to prevent root rot. Outdoor planting should be carried out at higher elevations to avoid waterlogging of plant stems and roots on rainy days, which can affect plant growth and quality.

🌱Plantation

Cutting: Cutting propagation commonly uses new buds sprouting from the roots as cuttings, which can be carried out in spring and autumn. In spring, cutting should be carried out when the sprouts have sprouted to about 15 cm, and in autumn, it should be carried out after the root zone sprouts after flowering. Splitting is generally carried out in spring and autumn, mainly targeting perennial old plants.

Splitting: Splitting can be done in both spring and autumn. Splitting is more suitable when sprouting in spring and after flowering in autumn. Directly excavate the sprouts and mother plants and plant them separately, or excavate the underground perennial roots and plant them separately. Each sub plant needs to have 3-4 apical buds when dividing. Especially double petal varieties are more suitable for branching. Split seedlings should be planted in well drained and loose soil, watered thoroughly after planting, and appropriately shaded with light intensity. For some perennial plants, it is necessary to forcibly separate them to avoid affecting their growth and flowering.

🪴Transplant

For burning hearts false sunflower , the best time for transplantation is from mid spring to early summer, when the temperature is mild and conducive to smooth root growth. The ideal conditions include a sunny area and well drained soil. Gently comb the roots during transplantation to promote growth and minimize plant stress.

❗Seasonal precautions

Burning hearts false sunflower is sown every spring and autumn. In slightly warm areas, there is no need for any protective measures when sown in March. It can bloom from June to July. In areas with lower temperatures, insulation and covering measures need to be taken to ensure the success rate of seed germination. If it is sown in September, settled in November, and transplanted again, it will naturally overwinter in winter and bloom in spring the following year.
