Basic Flower Care: The First Step After Receiving a Bouquet

After receiving flowers, performing basic care in a timely manner is the critical first step in determining the lifespan of the bouquet.

Handle Immediately

The golden rule of flower care is "speed". Handle them as soon as possible, because flowers dehydrate rapidly after leaving water. The sooner they absorb water, the better their condition will recover, and the longer their freshness will last.

Unwrap the Packaging

Although bouquet packaging is beautiful, it hinders air circulation and easily accumulates moisture and heat, accelerating bacterial growth and decay. Carefully remove all packaging to let the flower stems and leaves "breathe"; you can temporarily keep the tie to make handling easier.

Prepare the Vase

Cleanliness is a key point in flower maintenance. Choose a vase of appropriate size and wash the inside thoroughly with dish soap to remove dirt or bacterial films. If necessary, disinfect with diluted bleach (about 1:10), but rinse thoroughly. A clean vase reduces bacteria and is a guarantee for extending the flowering period.

Trim Flower Stems

This step is crucial. During transport, the cut ends of flower stems may dry out, be crushed, or be blocked by air, affecting water absorption. You need to trim them using sharp, clean tools.

• Angle: Cut diagonally at a 45-degree angle to increase the water absorption area and prevent the bottom from sitting flat against the vase, which affects water intake.
• Position: Cut off at least 2-3 cm from the end of the flower stem; if the end is withered, you can cut more.
• Method: It is recommended to cut diagonally in the air with a sharp, clean tool and then immediately place the flower stem into water to ensure the cut can quickly absorb water. Some views also advocate cutting underwater, believing this can more effectively prevent air from entering the vessels to form "air embolisms" that block water absorption; however, other views point out that cutting underwater may suck in impurities or bacteria from the water. Regardless of the method used, the key is to use clean tools to complete the cut quickly and ensure the flower stem can immediately contact clean water.
• Frequency: Re-cut the ends by 1-2 cm every time you change the water to keep the cuts fresh.

Remove Excess Leaves

Check the flower stems and remove all leaves that will be submerged in water. Leaves will rot in water, polluting the water quality, breeding bacteria, and blocking vessels, thereby shortening the lifespan. Keep leaves above the water line.

Add Clean Water and Preservative

Pour an appropriate amount of clean water into the clean vase. Regarding water temperature, for the initial treatment, consider using lukewarm water (about 37-43°C), which helps flower stems absorb water quickly to restore vitality. For daily water changes, it is recommended to use cool or room temperature clean water. Note that certain flower species (such as tulips) may prefer cold water.

Pour in an appropriate amount of clean water, ensuring all flower stem ends are immersed. Generally speaking, the water level can cover one-third to one-half of the stem length, but the specific optimal water level varies by flower type (e.g., roses need a deeper water level, while tulips and gerberas need a shallower level, see subsequent chapters for details); avoid water levels that are too low leading to insufficient water absorption.

Be sure to add flower preservative, which usually contains: 1. Sugar (energy); 2. Acidifier (aids water absorption); 3. Bactericide (inhibits bacteria). Dilute accurately according to instructions. If there is no preservative, the effect will be slightly inferior; the alternative method is to maintain extreme cleanliness and change water frequently, avoiding folk remedies.

Advanced Flower Maintenance Tips: Secrets to Prolonging Flowering Period

After completing basic care, daily flower maintenance is equally important. Advanced techniques can make flowers bloom longer.

The Science of Placement

The placement of flowers has a direct impact on their lifespan:

• Avoid direct sunlight: Strong light accelerates water evaporation and aging, leading to scorching and fading. Choose a bright indoor spot without direct sunlight.
• Keep away from heat sources: Do not place near heaters, air conditioner vents, or heat-generating appliances. High temperatures accelerate water loss.
• Avoid strong winds: Strong airflow will accelerate water evaporation leading to dehydration.
• Keep cool: Temperature affects lifespan. Try to place in a cool indoor area. Low temperatures at night slow down decay.
• Keep away from ripening fruit: Fruit releases ethylene which accelerates flower maturation and aging. Be sure to place them separately.

Water Quality and Frequency of Changing Water

Keeping the water source clean is the core of flower preservation.

• Frequency of changing water: It is best to change the water every day, or at least every other day. Change immediately if water quality deteriorates.
• Water choice: Use clean cool or room temperature tap water. If worried about chlorine, let it sit or use filtered water.
• Top up water: Flowers absorb water every day; pay attention to the water level and top up in time to ensure stem ends are immersed.
• Clean the vase: Rinse the inside every time you change the water. Thoroughly wash and disinfect every few days.
• Re-cut stems: Re-cut the ends of the flower stems every time you change the water to ensure smooth water absorption.

Make Good Use of Flower Preservatives

Make good use of flower preservatives: Preservatives are effective tools. Try to ask for them. Add new solution according to instructions every time you change water; do not reuse old solution.

Mist to Moisturize?

Mist to moisturize? Hong Kong's weather is humid so it is usually unnecessary, but for flowers requiring high humidity (like Hydrangeas) or in dry air-conditioned rooms, you can mist lightly occasionally. However, excessive misting can easily cause water accumulation leading to fungal diseases (especially for Roses and Carnations). Misting requires caution and ensuring ventilation.

Handle Withered Flowers and Leaves

Handle withered flowers and leaves: If you find withered flowers or yellowing/rotting leaves, remove them immediately. Because they affect aesthetics, release ethylene accelerating aging, and easily become a breeding ground for germs. Timely cleaning helps maintain bouquet health.

Rose Care Section: Cherishing Your Romance

Roses are one of the most popular flowers, and their flower maintenance has unique points that require extra attention.

Special Needs of Roses

Roses require a large amount of water and the water quality needs to be clean. Flower stems are easily blocked by bacteria and are sensitive to ethylene.

"Water Conditioning" and "Waking Up Flowers"

Newly received roses, especially those transported over long distances, may be dehydrated. Performing "water conditioning" or "waking up flowers" helps quickly restore vitality.

1. Prepare: Remove packaging, remove leaves and thorns below the water line.
2. Cut Stems: Cut stems significantly (3-5cm) at a 45-degree angle underwater.
3. Deep Water Soaking: Place in a deep bucket with warm water (about 37-43°C) and preservative, keeping the water level as high as possible. Warm water helps absorb water faster.
4. Placement: Let sit in a cool, dark, windless place to absorb water for at least 1-2 hours or overnight, allowing them to fully hydrate and stand upright.
5. Move to Vase: After waking up the flowers, move them to a display vase with room temperature clean water containing preservative.

Importance of Water Level

Roses need a large amount of water, so be sure to maintain sufficient water volume (covering at least 2/3 of the flower stem). Water levels that are too low can easily lead to insufficient water absorption and drooping heads.

Treating Bent Necks / Drooping Heads

Rose "bent neck" is usually caused by blocked stem vessels preventing water from reaching the flower head. You can try first aid:

• Re-cut Stems: Re-cut flower stems underwater (at least 2-3cm) to ensure the cut is fresh.
• Warm Water Soak: Place in warm water for about 30-60 minutes to observe if they can recover.
• Check for Air Embolisms: Cutting stems underwater is key to prevention.
• Wrap for Support: In severe cases, wrap with newspaper to help stand upright, then soak in deep water.
• Submerge Flower Head?: This method is controversial; it may be effective but also increases the risk of rot. Be careful and ensure dryness afterwards.

If ineffective, the flower may be severely dehydrated or aged.

Common Rose Preservation Questions

• Petal edges turning black/brown: May be due to physical damage, lack of water, ethylene, or early stage Botrytis. Check care and remove damaged petals.
• Buds not opening: May be due to variety characteristics, harvested too early, dehydration, temperature, or incorrect preservative. Ensure sufficient water and energy (use preservative containing sugar).

Care Points for Other Common Flowers

For other popular flowers in Hong Kong, understanding their characteristics for targeted flower care yields better results.

Lily

• Remove Anthers: After Lily anthers mature, they will shed a lot of pollen, easily staining petals, clothes, or furniture, and are difficult to clean. It is recommended to carefully remove them with tweezers or fingers before the anthers mature and crack (usually when the flower is half open). The main purpose of this operation is to prevent pollen contamination, and it has little effect on the length of the flowering period, and may even help extend the viewing time.
• Ethylene Sensitive: Be sure to keep away from ripening fruit.
• Water Level: Maintain a medium water level.
• Leaves: Timely remove leaves in water and withered yellow leaves.

Carnation

• Long Life: Long viewing period.
• Extremely Ethylene Sensitive: Extremely sensitive to ethylene; trace amounts cause wilting. Must be strictly kept away from fruit.
• Trimming Stem Nodes: There are different views on the best trimming position for Carnation stems. Some suggest cutting diagonally slightly above the node (the raised ring structure on the stem), while others suggest cutting between two nodes. Regardless of which method is chosen, using sharp tools to cut diagonally and ensuring the cut is smooth is most important.
• Water Level: Flower stems are relatively juicy; water level should not be too high when placed in water, and there is no need to spray flowers directly to avoid petal rot. Change water frequently and remove leaves submerged in water to maintain water cleanliness and extend flowering period.

Tulip

• Continuous Growth and Phototropism: They will grow taller and bend towards light in water, which is normal.
• Likes Cold Water: Tulips prefer cool environments and cold water, helping to keep them upright and slow down opening.
• Change Water and Cut Stems: Need to change water frequently and re-cut stems.
• Treating Bending: If stems are soft and bent, wrap with newspaper to stand upright and soak in cold water for a few hours to help recover.
• Water Level: Prefer shallow water levels. The water level in the vase does not need to be too deep, about 5 cm (2 inches) is enough, ensuring the ends of the stems are immersed in water, but avoid water levels that are too high.

Hydrangea

• Extremely Water Needy: Hydrangea flower heads are large with many leaves and strong transpiration, making them extremely prone to water loss and wilting.
• Maintain High Water Level: Maintain a high water level at all times.
• Mist Frequently: Petals and leaves benefit from frequent misting to moisturize, especially in dry environments.
• First Aid for Wilting: "Full body bath", immerse the whole flower (including flower head) in cold water for about 20-30 minutes to help recover.
• Treating Stem Ends: In addition to the standard 45-degree diagonal cut, there are some special treatment methods for Hydrangeas:
  (1) Dip in Alum Powder: Dip the freshly cut stem end (about half an inch) into alum powder (available in the spice section), believed to help promote water absorption.
  (2) Hot Water Treatment: Dip the stem end in boiling water for about 20-30 seconds, claimed to dissolve sap blocking water absorption.  
  (3) Cross-shaped Cut: To increase water absorption surface.

Lisianthus

• Leaf Treatment: Leaves are numerous and thin; be sure to remove leaves below the water line to prevent rot.
• High Water Quality Requirement: Need to change water frequently and use preservative.
• Gradual Opening: Buds open from bottom to top; remove withered flowers in time.

Gerbera

• Prone to Bent Neck: Gerbera flower stems are relatively soft and need gentle handling.
• Shallow Water Level: Do not like deep water; maintain 5-7 cm water level to prevent stem rot.
• Wire Support?: If received flowers have wire support, there is no need to remove it; generally no need to add it yourself.
• Avoid Misting: Prevent water accumulation in the flower center causing rot.

Myths and Common Mistakes in Flower Preservation

Regarding flower preservation, many practices circulate, some of which are myths or harmful. Common oversights also shorten the flowering period.

Myth 1: Can Soda, Coins, Aspirin, or Bleach Preserve Freshness?

• Soda: Sugar content is too high and easily breeds bacteria; not recommended.
• Copper Coins: Copper ion concentration is low, basically ineffective.
• Aspirin: Dosage is hard to control, may damage flower stems; not recommended. Studies have shown its effect on extending cut flower life is not obvious.
• Bleach: Concentration is hard to control and easily damages flower stems; high risk, strongly not recommended.

Conclusion: The most effective and safe way is to use flower preservative. If unavailable, focus on maintaining cleanliness (frequent water changes, washing vase, cutting stems).

Myth 2: Is Ice Water Always Best?

Ice water is not the best: Although low temperature helps preservation, ice water may cause cold shock to some flowers. For most flowers, cool or room temperature water is safer. Only a few cold-loving flowers (like Tulips) or for short periods benefit.

Myth 3: Is Misting All-Purpose?

Misting is not all-purpose: Although it temporarily increases humidity, for most flowers (like Roses, Carnations) it does more harm than good, conversely easily promoting bacterial or mold growth, leading to rot diseases. Only a few flowers requiring high humidity (like Hydrangeas) are suitable. Depends on flower type and environment. Usually, keeping the vase clean, changing water regularly, and trimming stems properly is enough to maintain flower hydration.

Common Mistake 1: Neglecting to Clean the Vase

Mistake 1: Neglecting to clean the vase. A common fatal mistake. Not washing the vase thoroughly leaves residual bacteria that will pollute water quality and shorten the flowering period. Rinse every time you change water, and scrub thoroughly regularly.

Common Mistake 2: Improper Placement

Mistake 2: Improper placement. Randomly placing near heat sources, direct sunlight, or near fruit are all mistakes. It will accelerate wilting. Should choose a cool, dark place away from heat sources and fruit.

Common Mistake 3: Not Regularly Trimming Stems

Mistake 3: Not regularly trimming stems. Cutting once is not enough. The cut will gradually become blocked. Must re-cut the end by 1-2cm every time you change water to keep it fresh.

Common Mistake 4: Improper Use of Preservatives

Mistake 4: Improper use of preservatives. Not using or not diluting according to the correct ratio. Must dissolve according to the indicated ratio for best results. Use new solution every time you change water.

Conclusion and Quick Reference Guide

Through correct flower preservation, flower maintenance, and flower care, the beauty of flowers can be extended longer. From immediate handling to daily maintenance and targeted care, every detail affects the flowering period. Avoid myths and mistakes, use preservatives, and continue to care, and flowers will surely repay your efforts. Hope this guide helps you care for the flowers in your home.
