Considerations Before Planting Orchids Outside

Before planting orchids outside, several key considerations must be taken into account to ensure their optimal growth and survival.

  • Climate and Temperature

Firstly, it’s important to understand the specific climate needs of the orchid variety you’ve chosen. Different orchids thrive in different temperature ranges. While some varieties are tolerant of a wide temperature spectrum, others are sensitive to minor fluctuations. The commonly grown Cattleya, Dendrobium, and Oncidium orchids, for example, do well in intermediate to warm temperatures — ideally between 60°F to 90°F. On the other hand, Masdevallia and Dracula orchids prefer cooler climates. [2]

  • Light Levels

Light levels are critical. Orchids require substantial light for photosynthesis, but the intensity varies among different species. While some species need high light levels, others require low to medium light. Bright but indirect light is usually the best for most orchids.

  • Humidity and Air Movement

Humidity is also a crucial factor for the health of orchids. Most orchids prefer a humidity level between 50% and 75%. [3] However, stagnant high humidity can lead to disease outbreaks, so ensuring good air movement is just as important as maintaining high humidity.

  • Watering

Watering needs are unique for different types of orchids. Epiphytic orchids need to dry out between watering sessions, while terrestrial varieties like to stay slightly moist. Overwatering is one of the most common mistakes that lead to orchid deaths.

  • Growing Medium

The choice of growing medium is crucial. Epiphytic orchids do best in loose, well-draining media like orchid bark or moss. Terrestrial orchids prefer a more conventional potting mix.

  • Pest and Disease Control

Finally, one must always be vigilant for signs of pests or diseases. Regularly inspect your orchids for signs of infestation and promptly treat any issues to prevent spread.

Investing time and effort into understanding these factors will not only enhance your orchid-growing skills but also contribute to the overall health and longevity of your plants, helping them to produce stunning, vibrant blooms that add unmatched beauty to your outdoor spaces.

Steps to Successfully Plant Orchids Outside

Now that we have talked about the considerations before planting orchids outside, let’s move forward to the practical steps involved in successfully planting orchids outdoors. These steps offer a simplified, straightforward process, even for beginners, making the entire experience of growing these exotic beauties less daunting and more enjoyable.

Species Selection

Selecting suitable orchid species for outdoor cultivation is crucial to success. Your choice should ideally be guided by your local climate, the specific conditions of your outdoor space, and your personal preferences.

If you live in a tropical or sub-tropical region, species like the Cattleya, Dendrobium, and Oncidium would be excellent choices as they thrive in warmer conditions. For cooler climates, opt for varieties such as Masdevallia or Dracula orchids that prefer lower temperatures.

Consider the light conditions in your outdoor space. If your space receives a lot of direct sunlight, choose species that can tolerate high light levels, such as Vanda orchids. On the other hand, Phalaenopsis and Paphiopedilum orchids are suited to shaded areas receiving less light.

Personal preference also plays a role in species selection. If you are drawn to a particular orchid for its color, shape, or size, you might be more likely to spend the time and effort needed to care for it properly.

Remember, it’s always beneficial to consult with local nurseries or orchid societies. They can provide valuable advice on the types of orchids that do well in your specific region, ensuring a healthy and vibrant orchid garden.

Location and Microclimate

After selecting the right species for your outdoor orchid garden, the next step involves determining the best location and understanding the microclimate of your garden.

The location where the orchids are planted in your garden can significantly affect their growth and blooming. Consider factors like the direction of the sunlight, the intensity and duration of light exposure, the presence of shading elements, and the proximity to walls or other structures.

For example, a south-facing location typically receives more sunlight than a north-facing one. However, intense sunlight can be detrimental to certain orchid species that prefer indirect lighting. Structures like pergolas or latticework can provide the necessary shade and create an ideal environment for these types of orchids.

The microclimate is another essential factor to consider. Microclimates are the specific climate conditions of a small area, which can vary significantly from broader regional climates. Factors contributing to the microclimate include temperature, humidity, wind speed, and the presence of other plants or bodies of water.

For instance, a corner of your garden sheltered by a wall might be significantly warmer than an open area, creating a microclimate suitable for warmth-loving orchid species. On the flip side, areas near a water feature might have higher humidity levels, perfect for orchids that enjoy moist conditions.

Soil and Substrate Preparation

Before planting, preparing the soil and substrate is an essential step. The choice of substrate largely depends on whether your orchids are epiphytic or terrestrial. Epiphytic orchids, commonly found growing on tree trunks in their natural environment, necessitate loose and well-draining substrates. These could include materials like bark chips, sphagnum moss, or a mix of both. The substrate must retain sufficient moisture to support the orchid, while also promoting rapid drainage to prevent root rot.

On the other hand, terrestrial orchids, which grow on the ground, prefer a more conventional potting mix. This could be a blend of peat moss, perlite, and compost, providing a balance of moisture retention and good drainage.

Remember to also consider the pH level of your substrate. Orchids prefer slightly acidic conditions, with a pH between 5.5 and 6.5. [4] This can be achieved by adding elements like pine bark or sphagnum peat moss, which naturally lower the pH level.

Preparation involves cleaning and sterilizing the growing medium to eliminate any potential pests or diseases. This can be done by baking the substrate in the oven for a couple of hours or pouring boiling water over it. Allow the substrate to cool completely before using it for planting your orchids.

Transplantation and Growing Technique

Transplanting your orchids and applying the correct growing techniques can significantly affect the success of your outdoor orchid garden.

Begin by delicately extracting your orchid from its present container. Gently untangle the roots and remove any dead or decaying material. To eliminate any residual potting mix, rinse the roots under lukewarm water.

Next, when preparing the substrate in a new pot or outdoor area, position the orchid in a way that places its oldest pseudobulbs at the pot’s edge and directs the newest growth towards the center.This arrangement gives the orchid room to grow. For epiphytic orchids, secure them to a tree or bark structure, ensuring that the roots are in contact with the substrate.

Once the orchid is in place, fill up the remaining area with your substrate, firming it gently around the roots. However, avoid compacting the substrate too much as this can prevent air circulation and water drainage.

Soil and Substrate Preparation

Watering and Mulching

Watering is a critical aspect of orchid care and should be tailored to the specific needs of the species in your garden. Most orchids prefer a cycle of thorough watering followed by a period of drying out. Overwatering can lead to root rot, a common issue that often leads to the death of the plant. An easy way to ascertain if your orchid needs watering is to feel the weight of the pot or the color of the roots. A light pot or silvery-grey roots are indicators that the orchid requires water.

Mulching serves as an excellent technique to conserve moisture, particularly for outdoor orchids exposed to harsh weather conditions. It acts as a protective layer, reducing water evaporation from the soil surface, and regulates the soil temperature. Organic mulches like bark chips, leaf mold, or compost also add valuable nutrients to the soil as they decompose over time. However, mulch should not be in direct contact with the orchid stems, as this can create a damp environment conducive to fungal and bacterial diseases.

Caring for Outdoor Orchids

To ensure your orchids thrive and bloom, regular care and maintenance are key. Monitor your orchids for signs of pests or diseases, such as discoloration, spots, or abnormal growth. Implementing a good pest management strategy, such as using organic insecticides or introducing beneficial insects, can support the overall health of your garden.

Orchids also benefit from regular feeding. A balanced orchid fertilizer, applied in accordance with package instructions, will provide the necessary nutrients for growth and blooming. However, be careful not to over-fertilize as this can cause root burn or excessive foliar growth at the expense of flowering.

Pruning is another important aspect of orchid care. Remove spent blooms and yellow or brown leaves to maintain plant aesthetics and health. For sympodial orchids, you can also prune back to the point where the plant has stopped producing new growth to encourage blooming.

Lastly, be mindful of seasonal changes. During colder months, you may need to provide additional protection for your orchids or even temporarily move them indoors if temperatures drop below the tolerance level of the species. By following these care guidelines, you can enjoy the beauty and exotic allure of outdoor orchids for years to come.
