How Much To Water Orchids

If you're new to the world of orchid care, the question of how much to water orchids might leave you feeling perplexed. These beautiful plants, with the captivating allure of their magnificent flowers and unique growth habits, have a fascinating relationship with water. To unravel the mystery of watering orchids, let's delve into the way orchids grow in nature and explore how much to water orchids and the benefits of using saved rainwater, distilled water, or reverse osmosis water for their optimal nutrient uptake.

Orchids are Air Plants

Most orchids in cultivation today are epiphytes, often referred to as air plants. In their natural habitats, many orchids call the lush tropical regions home, where they have evolved ingenious strategies to secure moisture and nutrients from the environment. Unlike traditional potted plants, these botanical marvels do not rely on soil for their roots to thrive. Some of their roots act as anchors, gripping onto trunks and branches, while the rest reach out into the air where their sensitive outer skin collects moisture from the mist, rain, and dew that nature generously bestows upon them. They also receive nutrients from animal droppings, decaying organic matter and minerals leaching from the trees that they grow in. They are not parasitic, so they do not take anything from the trees that they grow in other than the minerals that leach from the bark when it rains.  

How Orchids Absorb Water

But how do they quench their thirst without the luxury of soil? This is part of orchid's mysterious allure and here's where their sensitive outer skin comes into play. Orchids have evolved to possess a unique ability to collect moisture from various sources such as mist, rain, and dew. Their outer skin, called the velamen, acts as a sponge, absorbing and retaining moisture to sustain the plant during periods of drought.

Understanding this remarkable adaptation provides valuable insight into their watering requirements. Orchids have evolved to rely on intermittent water availability, making them highly sensitive to overwatering. Since they also like a lot of airflow, their sensitive roots are prone to rot if exposed to excessive moisture for prolonged periods. Therefore, striking the perfect balance between an ideal amount of water and avoiding waterlogged conditions in the growing medium is essential for their well-being. As for how much to water orchids, a general rule of thumb is to water your orchids once on a weekly basis. We go into more detail in this article on how to water orchids. 

The Best Type of Water

Water is water, right? Actually water can be classified as either hard or soft, and municipal water is usually treated with chemicals, so let's look at our choices. When it comes to watering orchids, utilizing saved rainwater, distilled water, or reverse osmosis water holds tremendous advantages. These water sources offer a multitude of benefits that contribute to the orchid's overall health and nutrient uptake.

Rainwater

Saved rainwater, as nature's gift, possesses inherent qualities that make it a fantastic choice for orchid hydration. It is soft, devoid of harsh chemicals, and rich in nitrogen, a vital nutrient for growth. Collecting rainwater and using it to quench your orchids' thirst not only replicates their natural habitat but also ensures a pure and nourishing source of water.

Distilled Water

Distilled water, obtained through the process of steam distillation, emerges as another excellent option for orchids. It undergoes rigorous purification, removing impurities, minerals, and contaminants. By using distilled water, you create an environment free from mineral buildup, safeguarding your orchids' delicate roots and facilitating optimum nutrient uptake when mixing it with fertilizer

Reverse Osmosis Water

The Problem with Hard Water 

The importance of using saved rainwater, distilled water, or reverse osmosis water becomes even more apparent when considering the impact of hard water on orchids. Hard water contains high levels of dissolved minerals, such as calcium and magnesium, which can accumulate on the roots and in the potting medium over time. These minerals can obstruct nutrient uptake, leading to deficiencies and compromised growth in your cherished orchids. 

How Much to Water Orchids

Now you can appreciate that how much to water orchids is a delicate art. Remember, these air plants have adapted to intermittent water availability, making overwatering a perilous pitfall and is actually the number one reason that new orchid growers experience failure. Harnessing the secrets of their natural growth habits and providing them with saved rainwater, distilled water, or reverse osmosis water allows you to create an environment that nourishes and supports thriving orchids. As a general rule of thumb, water your orchids once on a weekly basis and explore the navigation links above to learn more about precision watering and fertilizing.  So, take a leap into the mesmerizing world of orchids, and let their thirst-quenching secrets guide you to horticultural bliss.

Orchid Growing tip: Here's an interesting tidbit about kelp seaweed and its role in orchid flower production! Kelp seaweed contains a group of plant hormones called cytokinins, which are like nature's very own floral cheerleaders. These cytokinins have a remarkable ability to stimulate cell division and promote overall plant growth. When applied to orchids, these magical compounds from kelp seaweed can work their wonders by signaling the plant to shift its focus towards flower production. It's as if the orchids receive a backstage pass to a spectacular blooming show, all thanks to the extraordinary powers of cytokinins found in humble kelp seaweed. So, next time you're marveling at the magnificent blooms of your orchids, take a moment to appreciate the role of kelp seaweed and its cytokinins in orchestrating this botanical masterpiece.

Fun Facts About Orchids: Did you know that vanilla, the beloved flavor found in countless desserts and beverages, actually comes from orchids? That's right! The delicious and aromatic vanilla bean is derived from the vanilla orchid, specifically the species Vanilla planifolia. This orchid produces delicate, pale yellow flowers that need to be hand-pollinated in order to bear fruit. After pollination, the flowers develop into long pods, which are carefully harvested and undergo a curing process to develop the distinct vanilla flavor. So, the next time you enjoy a scoop of vanilla ice cream or savor the aroma of a vanilla-scented candle, remember that it all started with an orchid!
