Water is an essential element for plants. In addition to hydrating plants, it helps transport nutrients from the soil to plant cells. In addition to this, the evaporation of water caused by the phenomenon of transpiration helps to regulate the temperature of the plants and cool them. That said, although water is vital for plants, you can choose to water them, during their growth period, with a liquid fertilizer, which will be responsible for both hydrating flowering plants and nourishing them, to stimulate their growth and flowering . To enjoy a spectacular bloom of orchids, you can water them with green tea.

Green tea is a very effective fertilizer to stimulate the flowering of orchids and keep them healthy. In fact, it is rich in essential elements for plant growth such as nitrogen, phosphorus, and potassium. To use this natural fertilizer, simply infuse a few green tea leaves in hot water and let this infusion cool. Then use the solution to water the orchids. This liquid fertilizer can be used once a month, during the spring and summer. Also, use this fertilizer sparingly, as any excess could cause flowers and leaves to drop.

In addition to watering your orchids with green tea, you can also take green tea bags and spread their contents over the orchid soil in the pot.

What other fertilizers are there to help orchids bloom?

In addition to watering orchids with a green tea infusion, you can use these liquid fertilizers to boost their bloom.

  • Egg cooking water to get orchids blooming again

After boiling the hard-boiled eggs, save the cooking water. Allow it to cool and then use it to water your orchids. Eggshells have a good content of calcium, magnesium, carbonate, and phosphorus. These minerals pass into the cooking water of the eggs and are used to fertilize the plants.

  • Banana peels to stimulate orchid blooms

Banana peels are rich in potassium and nitrogen. To get your orchids blooming again, mix organic banana peels with water. Leave for 24 hours, then use this liquid to water the orchids.

  • Rice cooking water to boost orchid blooming

Rice water is a good fertilizer for plants. This natural fertilizer is rich in starch, nitrogen, phosphorus, and potassium. In addition to stimulating plant growth, it improves their photosynthesis process and stimulates the growth of good bacteria in the soil. To stimulate orchid blooming, simply collect this water, let it cool, and then use it to water your orchids. Keep in mind that rice cooking water isn’t the only liquid fertilizer beneficial to plants. Cooking water from starchy foods like potatoes or pasta can also be helpful for your plants.

These natural fertilizers allow you to obtain a spectacular flowering of your orchids, while hydrating them.
