Autumn chrysanthemums:

 

Care and fertilization after

 

cuttings and pinching

Chrysanthemums, one of the world's three major cut flowers, second only to roses, enjoy sun, drought, and fertilization. If you want to propagate chrysanthemums at home through cuttings, the most important factors are cuttings, pinching, and post-bud development fertilization.

1. Before and after cuttings: Root Forte 110 (1.5-0-1.5)

The suitable season for cuttings is in spring or early summer. The chosen cultivation soil can be a mixture of sandy soil, peat soil, organic fertilizer, or a little slow-release chemical fertilizer. The cuttings should be cut the main stem into about 10 cm pieces, leaving 2-3 buds, including the top bud and the underground buds that will grow into the root system. The underground part should be cut at an angle to facilitate water absorption, and only two leaves should be left on the upper part. The cut cuttings should be soaked in rooting water made by diluting Root Forte 110 (2-3 drops per liter) for 1 hour. After that, use a wooden chopstick to poke a 4-5 cm hole and plant it in the above-mentioned mixed soil. Water the soil and leaves thoroughly and use a clear plastic wrap to maintain high humidity for bud growth and to prevent direct sunlight. During this period, occasionally open the plastic wrap to check the growth of the buds and water to keep the soil moist.

Approximately two weeks after cuttings are planted, when the root system begins to develop and starts to absorb nutrients, the roots can be watered with a 500 times diluted solution of Root Forte 110. Subsequently, every week, the leaves or roots should be sprayed or watered with a solution diluted 1000 times with the Root Forte 110 and this regimen helps promote the healthy growth of the root system.

 

2. After pinching: Full Energy 100 (NPK 3.5-3.0-3.0)

To ensure the chrysanthemums bloom prolifically, brightly, and uniformly, and to prevent excessive growth during the nutritional growth period that could affect its aesthetic appeal, it's necessary to pinch off the top when the main stem reaches about 10 centimeters in length. This practice promotes the growth of lateral buds. After the lateral buds that sprout following the pinching grow into 5-6 leaves (approximately a month), pinch off the top again, and continue until the beginning of autumn (around early August). After each pinching, water the roots with a 500 times diluted solution of Full Energy 100. During the period between two pinching events, spray the leaves with a 1000 times diluted solution of Full Energy 100 each week, to promote the nutritional growth of the plant.

 

3. Bud development: Go Color 601 (NPK 4.0-3.0-2.0)

After the beginning of autumn, the length of daylight decreases, temperatures drop, and these environmental changes promote bud growth. At this point, start watering the roots with a 1000 times diluted solution of Go Color 601. Afterward, every two weeks, spray the leaves with a 2000 times diluted solution of Go Color 601, continuing until the buds appear, at which point you should stop fertilizing. Go Color 601 contains a variety of organic molecules and chelated minerals, which can promote more abundant flower buds, vibrant petal colors, and vigorous blooming. It also helps prevent the flower stalk from aging and falling, thereby extending the flowering period.

Ingredients: Magnesium nitrate, potassium dihydrogen phosphate, calcium gluconate, EDTA-iron, EDTA-manganese, EDTA-zinc, copper sulfate, boric acid, sodium molybdate, lignin, cyclic adenosine monophosphate, vitamins B1 and B12, and seaweed extract.

(1)The nitrogen, phosphorus, and potassium ratio is suitable for floral crops and promotes continuous flowering.

(2)An appropriate amount of calcium prolongs the flowering period.

(3)An appropriate amount of manganese, magnesium, and iron provides the nutrients needed for color change.

(4)The root development ratio of zinc, molybdenum, and the B vitamins promotes increased bud points and flower bud differentiation.

(5)An appropriate amount of boron promotes the absorption of large molecular elements, and copper enhances metabolism to make the overall flowering vigorous, bright, and long-lasting.

 

Hurry and multiply your pots before autumn arrives, let your balcony bloom with clusters of flowers, making every moment beautiful with chrysanthemums!
