Read about low-cost, natural Things You Can Add to Orchid Soil for Bigger, Healthier Blooms and stronger roots.
Orchids are beautiful flowers, but they can be a little tricky to grow. If your orchid isn’t blooming well, the problem might be in the soil. Orchids don’t grow in regular garden soil. They need loose, airy soil that lets their roots breathe. Luckily, there are many things you can add to orchid soil to help your plant grow stronger and produce more flowers. Let’s take a look at what works best.
Things You Can Add to Orchid Soil for Bigger, Healthier Blooms
1. Bark Chips
Most orchid mixes start with bark chips. These help create air pockets so the roots don’t sit in water. Good air circulation around the roots is key for healthy orchids. You can use fir bark, pine bark, or redwood bark. Bark breaks down over time, so replace it every year or two.
2. Sphagnum Moss
Sphagnum moss holds moisture while still allowing air to flow. It’s perfect if your orchid dries out too quickly. You can mix it with bark or use it alone, depending on your orchid type. Just don’t pack it too tightly, or it will hold too much water.
3. Perlite
Perlite looks like small white stones. It keeps the soil light and helps with drainage. It also stops the mix from getting too compact. Mixing perlite with bark and moss gives your orchid the right balance of air and moisture.
4. Charcoal
Activated charcoal helps remove toxins and keeps the soil fresh. It also absorbs extra moisture, which is helpful if you tend to overwater. Add a small amount to your orchid mix to keep it clean and healthy.
5. Coconut Husk
Coconut husk chips are similar to bark, but they hold moisture longer. They break down slowly and are a good choice if you live in a warm or dry area. Many growers like them because they’re eco-friendly.
6. Clay Pellets
Clay pellets or LECA (Lightweight Expanded Clay Aggregate) are often used in semi-hydroponic growing. They hold moisture at the bottom while letting the top stay dry. Orchids grown in LECA can develop strong roots and grow very well if cared for properly.
7. Worm Castings
Worm castings are rich in nutrients and act like a natural fertilizer. Add a small amount to your orchid mix for a gentle, steady boost of nutrients. They help promote green leaves and healthy flower spikes.
8. Crushed Eggshells
Crushed eggshells are a natural source of calcium, which strengthens your orchid’s cell walls. Sprinkle a small amount into the mix now and then. Be sure to rinse and dry the shells before using them.
9. Slow-Release Fertilizer
Adding a slow-release orchid fertilizer to the soil can help feed the plant over time. Choose one made for orchids, and follow the instructions carefully. Too much fertilizer can burn the roots, so use it sparingly.
10. Cinnamon
If you’re worried about fungus in your orchid soil, sprinkle a little cinnamon powder. It’s a natural antifungal and can help keep the roots healthy. Don’t overdo it—just a light dusting is enough.
