For those of us eager to see our indoor flowers and plants thrive with lush greenery and abundant blooms, a simple yet potentially powerful homemade top dressing might be the answer. This organic concoction, as described in the Spanish article you provided, aims to stimulate plant growth, enhance soil fertility, and help weak plants regain their vigor. It also suggests boosting immunity, improving photosynthesis, and accelerating the plant’s metabolic processes, potentially preventing fungal diseases and ensuring prolonged flowering for your favorite indoor greenery.

Why Consider This Homemade Top Dressing?

Many popular houseplants, including geraniums, violets, impatiens, and ferns, are said to benefit from this type of feeding. It claims to provide essential nutrients and naturally improve plant health, potentially reducing the need for synthetic fertilizers. Additionally, ornamental foliage plants are reported to respond well, leading to vibrant leaves and increased growth.

This homemade fertilizer features just two readily available ingredients: milk (or whey) and iodine (specifically Lugol’s solution with glycerin). Each component is suggested to play a crucial role in nourishing and protecting plants:

The Benefits of Milk or Whey for Plants:

Milk is a natural source of calcium, which is essential for strengthening plant cell walls and promoting healthier growth. It also contains proteins, amino acids, and beneficial microorganisms that can enrich the soil, making it more fertile. When watered into the soil, milk is believed to encourage the activity of beneficial bacteria, improving the absorption of nutrients by plant roots.

Furthermore, the presence of lactic acid bacteria in whey is suggested to act as a natural antifungal agent, helping to suppress harmful fungi and bacteria that can cause root rot and other plant diseases. Regular use of milk or whey in plant care is claimed to significantly improve the overall health of flowers and indoor greenery.

The Role of Iodine in Plant Growth:

Iodine is the other key ingredient in this top dressing. While plants require only trace amounts of iodine, it’s said to play a vital role in stimulating enzyme processes and overall plant metabolism. It’s also claimed to help increase disease resistance, support robust growth, and enhance flowering potential.

The article specifically mentions Lugol’s solution containing iodine and glycerin. Glycerin is suggested to help retain moisture in the soil, preventing it from drying out too quickly. This could be particularly beneficial for indoor plants that prefer consistently slightly moist conditions.

How to Prepare This Top Dressing for Your Plants:

Preparing this potentially effective fertilizer is described as quick and easy. Follow these simple steps to create a nutrient-rich solution for your indoor plants:

Ingredients:

• 1 liter (approximately 4 cups) settled or filtered water. Avoid using tap water immediately, as chlorine can be harmful to plants. Let it sit for 24 hours before use.
• 100 ml (approximately 1/2 cup) milk or whey
• 3 drops of Lugol’s iodine solution with glycerin (available at some pharmacies or online)

Instructions:

1. Take 1 liter of settled or filtered water at room temperature.
2. Add 100 ml of milk or whey to the water and stir well to combine.
3. Next, add 3 drops of Lugol’s iodine solution and mix thoroughly to ensure even distribution.
4. Your top dressing is now ready to use!

How to Apply This Top Dressing to Your Plants:

This nutrient-rich solution can be applied in two ways:

1. Watering at the Base:

   • Gently pour the prepared solution onto the soil at the base of your plants, ensuring the soil absorbs it well.
   • It’s best to apply this fertilizer to slightly moist soil to prevent potential root burn.
   • For optimal results, use this top dressing once every two to three weeks.

2. Spraying on the Leaves (Foliar Application):

   • Pour the solution into a spray bottle.
   • Lightly mist the leaves of your plants, avoiding excessive wetting, which could attract pests or lead to fungal issues.
   • Foliar spraying is suggested to be particularly beneficial for ornamental foliage plants like ferns, as it enhances their lush appearance.

Additional Tips for Maximum Effectiveness:

• Use Fresh Ingredients: Prepare a fresh batch of this top dressing each time you use it to ensure maximum potency.
• Apply in the Morning or Evening: Avoid applying during the hottest part of the day to prevent leaf scorch from sunlight.
• Test on a Small Area First: Before applying to all your plants, test the solution on a small area of one plant to ensure there are no adverse reactions.
• Combine with Other Natural Fertilizers: This top dressing can be used in rotation with other organic fertilizers like banana peel infusions or onion skin solutions to provide a broader range of nutrients to your plants.

Expected Results (According to the Article):

Important Considerations for US Gardeners:

While the Spanish article presents this as a beneficial method, it’s important to note that scientific evidence supporting the widespread use of iodine as a plant fertilizer is limited. Plants do require iodine as a micronutrient, but usually in extremely small amounts. Excessive iodine can be harmful to plants and soil microbes.

Lugol’s solution, while available in the US, is typically used for medicinal purposes. Ensure you are purchasing the correct type and concentration. Exercise caution when handling iodine solutions.

While milk can provide some nutrients and potentially act as a mild fungicide, excessive use can lead to unpleasant odors and fungal growth on the soil surface.

It’s always recommended to research and understand the specific needs of your plants before applying any homemade fertilizer. What works well for one type of plant might not be suitable for another.
