Orchid Flower Spike Care

It is always so exciting when we find a new flower spike on our plants. The end result of proper orchid flower spike care is a rewarding cascade of beautiful flowers, which is the whole reason that we love to grow orchids. So let's talk about the sequence of steps to take from start to finish. 

Identifying A Flower Spike

When you first notice a flower spike, it may be difficult to determine whether it is a new root or a flower spike, but the difference will become apparent in just a few weeks. A root will have a uniform shape with a rounded top and a flower spike while looking similar to a root, will have a noticeably different tip. Also roots on Phalaenopsis will have a grayish appearance when dry, while a flower spike will remain green and start to develop nodes where the flowers will appear.

Orchid Flower Spike Care: A Guide to Stunning Blooms

There’s nothing more thrilling than spotting a new flower spike on your orchid! With proper orchid flower spike care, you’ll be rewarded with a breathtaking cascade of blooms—the very reason we adore these enchanting plants. In this guide, we’ll walk you through the steps to nurture your orchid’s flower spike from its first appearance to a stunning display of flowers.

Identifying a Flower Spike

When you first notice a new growth, it can be tricky to tell whether it’s a root or a flower spike. Here’s how to tell the difference:

  • Roots: Have a uniform shape with a rounded tip and a grayish appearance when dry.
  • Flower Spikes: Remain green and develop small nodes where flowers will eventually emerge.

On Phalaenopsis orchids, flower spikes often grow between the leaves, while roots tend to emerge from the base of the plant. Within a few weeks, the distinction will become clear, and you’ll know you’re on your way to a beautiful bloom!

Light Requirements for Orchid Flower Spike Care

Light plays a crucial role in orchid flower spike care. During the early stages of growth, the flower spike is flexible and will naturally grow toward the light source. Here’s how to guide its growth:

  • Natural Light: Place your orchid near a window with bright, indirect light. The spike will grow toward the window, but you can train it to grow straight using a stake.
  • Supplemental Light: If you’re growing multiple orchids, consider using a compact fluorescent or LED grow light to encourage healthy spike development. For a high-end solution, the Gardeners Supply Indoor Greenhouse provides full-spectrum lighting perfect for orchids.

Keep light sources at least 12 inches away from your plants to avoid burning the delicate spike.

Staking for Proper Orchid Flower Spike Care

While orchids in nature don’t require staking, it’s a helpful technique for cultivated plants. Staking ensures your flower spike grows straight and provides support for the heavy cascade of blooms to come. Here’s how to stake your orchid:

  1. Choose the Right Time: Begin staking when the flower spike is 5-6 inches long and still flexible.
  2. Position the Stake: Place the stake about one-third to one-half the distance between the orchid stem and the pot’s edge. Avoid areas where roots are likely to circle the pot.
  3. Secure the Spike: Gently tie the spike to the stake using a soft plant tie or yarn. Be careful not to force the spike—just guide it into place.

For a professional touch, consider using adjustable orchid stakes and soft plant clips to secure the spike without damaging it.

Cascading the Bloom

As the flower spike matures, it will begin to produce buds and eventually bloom. This process can take 2-3 months, depending on the orchid species. Here’s how to create a stunning cascading display:

  • Continue Training: Loosely tie the spike to the stake as it grows, ensuring it remains supported.
  • Use Light to Guide Growth: If your orchid is near a window, the spike may naturally curve toward the light. You can also use artificial light to direct its growth.
  • Aesthetic Finishing Touches: Once the spike is fully developed, replace ties with decorative clips for a polished look. Trim the stake just below the last node to maintain a clean appearance.
