Proper planting and care techniques result in beautiful Rhododendron pots.

Steps to Plant Rhododendron Flowers

Choose a Variety

Currently, the Belgian variety of Rhododendron is widely used in the market. This variety features small plants, abundant blooms, and large flowers, with some producing two colors. The planting methods can include seeding, cutting, or layering, with cutting and layering yielding quicker results than seeding.

Soil Requirements

The Belgian Rhododendron requires acidic soil; planting in alkaline soil can kill the plant. The soil must be loose, well-draining, aerated, rich in organic matter, and adequately fertilized. A pH level of around 4 to 5 is ideal. To create the best soil for Rhododendrons, mix soil with organic matter from conifer needles or decomposed pine leaves.

A key consideration when planting Rhododendrons is soil quality.

Choosing a Pot

Select a pot that is proportionate to the plant; larger pots with more soil will retain more water. The pot should have large drainage holes at the bottom and a wide opening to allow for evaporation and quick drainage. Choose a shallow pot as Rhododendrons have shallow roots. When planting, use a pot with drainage holes, place a nylon mesh at the bottom, and add a layer of broken bricks and gravel about 2-3 cm thick on top.

Fill the pot with soil to about 1/2 to 2/3 full, ensuring that the root system is free, then add more soil and gently press down with your hands. If you notice roots growing out of the bottom of the pot, it’s time to repot into a larger pot and replace the soil with the prepared mixture.

Choosing the right pot is crucial for planting techniques.

Watering Techniques for Rhododendron

Rhododendrons have a strong root system, making them sensitive to drought and prolonged waterlogging. Both conditions can hinder growth, causing yellowing leaves and wilting flowers. Therefore, it’s essential to adjust the watering schedule according to weather conditions. The best times to water are early morning or late afternoon. During the growth phase and blooming period, they require more water. On dry days, spray water around the leaves, flowers, pot, and soil to increase humidity.

Watering Principles: After planting and nurturing new shoots and buds, do not water if the surface soil is not dry; just keep it moist. Water every 10-15 days with a diluted vinegar solution (10%), or use diluted rice water or fermented bean water. Water with diluted urine every 5-10 days. Additionally, every month, water with a diluted iron sulfate solution (0.5-1%) to prevent yellowing leaves. If iron sulfate is unavailable, soaking rusted iron in water and using the diluted solution works as well.

Fertilizing Techniques for Rhododendron

Rhododendrons are not heavy feeders, so it’s important to be cautious when fertilizing. Over-fertilizing or using concentrated fertilizers can negatively impact plant growth. To achieve large and beautiful flowers, apply an appropriate amount of fertilizer, with expert recommendations suggesting less dry fertilizer and more diluted liquid fertilizer.

Generally, fertilization is only necessary for plants from 2 years old and up. For 2-3 year-old plants, fertilize from late spring to early summer, every 10-15 days with diluted fertilizer. For plants of 4 years and older, fertilize twice a year with dry fertilizer in spring and fall, adding phosphorus and potassium fertilizers once in mid-June. Stop fertilizing after June until the flowers fade, and new branches emerge before applying diluted liquid fertilizer.

Some notes when fertilizing:

• Avoid fertilizing excessively during summer to prevent yellowing and leaf drop.
• If the plant is growing normally during summer and entering a growth phase, apply 1-2 times of Ca3(PO4)2 + Ca(HPO3) to promote flower bud development.
• After each fertilization, increase watering and till the soil.
• No fertilization is needed after winter.

Caring for Rhododendron Flowers

• Pruning: Trim branches that are diseased, weak, or overcrowded, and shape the plant to encourage desired growth. Pruning can be divided into two phases: the growing season and dormancy. During the growing season: pinch tips, bend branches, and adjust density.
• Dormancy Phase: Primarily trim diseased and weak branches. Shorten old branches to encourage new growth.
• Indoor Care: When displayed indoors, ensure the plant is in a well-lit, breezy area. Move the pot outside daily and leave it overnight. During the flowering period, avoid watering directly on the flowers. Do not keep the pot indoors for too long; it should be moved to the garden for care within about one month.

• Adjusting the Blooming Period: Blooming conditions (light and temperature): Daytime > 27^oC, nighttime > 18^oC for abundant flowering. Flower buds also require light exposure from 5 AM to 4 PM daily.
• Flower Bud Differentiation and Blooming: Influenced by the characteristics of each species.
• Methods for Early Flowering: Enhance care to encourage rapid growth of new branches. Once the plant has completed bud differentiation, reduce watering, provide gentle lighting, lower the temperature, and ensure the soil remains moderately moist…

Rhododendrons are beautiful flowers suitable for ornamental planting, creating a striking and aesthetic space for the home. With proper planting and care, rhododendron plants can live for a very long time.

Meaning of Rhododendron Flowers

When discussing the significance of rhododendron flowers, we cannot overlook the legend surrounding this flower. An ancient tale tells of a couple who lived happily in a small village. During the day, the husband often ventured into the deep forest to hunt and gather firewood, but one day, he went out and did not return.

The wife waited anxiously for her husband for one month, two months, then three months, without any news. One day, she decided to pack and venture into the deep forest to find him. However, fate seemed to play tricks on them; on the morning she set out, her husband returned in the afternoon, and they missed each other. Hearing the story from their neighbors, the wife turned back to search for her husband in the forest.

Meanwhile, the wife searched day after day but found no trace of her husband. One day, exhausted, she collapsed and died beside a rock. Later, a beautiful flower grew in that spot, which released a fragrant scent every spring. After her death, the wife’s spirit met an Elder who listened to her tale and named the flower “Rhododendron.”

As for the husband, along his journey, he called out his wife’s name endlessly. After many days without news, he too collapsed from exhaustion right by that rock. His spirit transformed into a solitary bird that sang every evening at sunset. The Elder, touched by the love of this couple, named the bird “Quyen” (which can be read as “Forget”). Later, the people, wishing for the couple to reunite in happiness, named the flower “Rhododendron.”

The meaning of the rhododendron flower symbolizes the love between couples and the loyalty and faithfulness of marriage. In China, rhododendrons are also regarded as symbols of gentleness, elegance, and femininity. Beyond these meanings, rhododendrons hold many other significances.

In feng shui, rhododendrons symbolize warmth, togetherness, dispelling negative energy, and bringing good luck to the homeowner. Thus, during the Lunar New Year, families love to plant these flowers as a way to ward off misfortune and pray for good luck to come to all household members.
