Find out if terracotta makes good orchid pots

Pots on the Cheap

First off, terra cotta is cheap and widely available. If it breaks, it won’t be difficult to find a replacement.

Terracotta is heavy. This is a good thing when you have a top-heavy orchid.

Porous is a Plus

First, terra-cotta is porous, which means that the pot will absorb water. The blessing is that you can tell when the potting medium is dry because the the pot will be dry as well.  Because it is so easy to assume potting medium is dry when looking at the top portion of the potting mix, a cool, damp terracotta pot can clue you in on the dampness of the orchid mix.

Orchids do not like to sit in standing water. Terracotta will alleviate this problem by wicking away excess water. The curse is that if the pot gets too dry, the clay pot will absorb water away from the orchid’s roots.

Tip: One remedy for minimizing terracotta’s tendency to wick water from the orchid is to water both the pot and the orchid. To do this, soak the orchid in the terracotta until the pot has absorbed all the water it can hold.

Minimizes Fertilizer Salts

Personally, I like the look of a mineral-stained terra cotta pot. It’s just so authentic looking. However mineral stains serve another important function beyond aesthetics. Mineral salts introduced through fertilizers are absorbed out of the potting mix and to the outside of the terra-cotta pot. This is a benefit that plastic and earthenware pots can’t compete with.

Air Flow

Another benefit that plastic and pottery can’t boast is that terra cotta allows oxygen to pass through to the roots. Air circulation isn’t just a good thing for orchid leaves, it’s vital for optimum orchid root health.

Without a doubt the orchid roots will stick to the terracotta. This isn’t a problem…until it is time to repot. Then, repotting becomes a beast. The roots will either have to be torn away from the pot or snipped off.

Opacity

A downside is that terra cotta is opaque which means that you will not be able to see the orchids roots and soil. To off-set this disadvantage, use pots with slots. Purchasing terra cotta with slatted sides or with large holes are more expensive than those without, but do have the advantage of allowing you to see into the potting mix and the roots.

To offset the disadvantage of terracotta’s opacity, buy a pot with holes, or use a drill with a masonry bit and drill holes in the side.

Drill holes with masonry bit for DIY orchid pot

Soak the pot in water for at least 24 hours. Using a masonry bit, drill holes in the sides and bottom of the pot. Be sure to wear protective eye-wear when drilling. Drill on a hard, stable surface such as your driveway or a sidewalk. This will prevent too much vibration.  At first you may wonder if your making any progress. Be patient and the drill will do its work.

Roots Stick

The main disadvantage to terracotta is that orchid roots will stick to the pot. There is no maybe, it will happen. Sometimes the only way to extricate the roots from the pot is to break the pot. Many of the roots will have to be cut from the pot with scissors.

I repotted this orchid when my photo backdrop fell and pushed the orchid to the ground, breaking the pot. The orchid survived, but the pot did not. I had to carefully extricate the roots that had tenaciously stuck to the pot.

Have Your Cake and Eat It Too

There are advantages and disadvantages to terracotta pots. The downsides are:  the opacity of the pot and that the roots will stick. The more experienced you become the better orchid water-er you will be, downplaying the necessity of being able to see the roots. Also, a healthy orchid will bounce back from the trauma of potting.

And, there are many upsides to terracotta. Its weight. A heavy terra-cotta pot can counter-balance a top-heavy orchid. Second its porousness. The fact that terracotta absorbs water can tell you when your orchid needs watering. Also, terracotta draws salts out of the potting mix to the outside of the pot. The third advantage is air circulation. Air flow to the roots is a very good thing.

The Bottom Line

The more experienced you are at growing orchids, the more terra cotta will work for you. Paramount to healthy orchids is healthy roots. To help see the orchid’s roots better, buy terra cotta with slats, or make your own holes with a masonry bit. In fact, even if you give your orchids the perfect amount of water, terracotta with slats or holes is still a good idea.

If you’ve got watering down, give terracotta a try.

If you are still working on watering properly, don’t go with terracotta, go with a clear liner pot.

    I asked the question about terra cotta pots at the orchid show at Red Butte in April… because I love the way the pots look and thought they might cure the top-heavy problem. The two instructors said unless I want to smash my orchid out of the pot one day, absolutely don’t use them. Which made me very sad! They explained why the clear inner pots are so much better and I’ve looked on Amazon and found that they are only sold at 4×4, 5×5, 6×6, (and so on) inch increments. I have a phaleanopsis that is growing up and out of the clear pot it came in, becoming much “taller” than the pot. Does that mean I should re-pot and increase the circumference as well? The reason I ask is because in the same Orchid 101 class the instructor said that the roots should always be touching the wall of the pot, not lost inside a bunch of bark. What should I do?

      Carolyn,
      Yes roots will always stick to terra cotta and smashing the pot to remove the orchid is common practice. Still, some growers prefer terra cotta. They may not be a good option for everyone, but they are still a viable option. Some growers will only grow in terra cotta, while others only in clear plastic. Clear slotted plastic has some advantages: roots don’t stick and, you can see inside the pot to check on the roots and soil. Follow this link for different pot sizes: Slotted Clear Orchid Pots – Growers Assortment.

      Yes, orchids like to be crowded in their pot. One reason that an orchid may fail to bloom is that the pot may be too large. Once an orchid has reached maturity it can stay in the same size pot indefinitely. If an orchid has out grown a a pot, just go up one size.

      I can’t tell you if you should go up a pot size or not because I don’t know what your orchid root system is like. After unpotting your orchid you will have a better idea of how healthy the roots are and what size of pot you will need (that’s why a variety of pot sizes is so useful). Use the smallest size pot that all the roots will fit into.

      Please, let me know if I can be of further help.

    I bought my orchids on clearance from Lowe’s and Walmart without any flowers. I brought them back to life by repotting them in wire baskets (Easter Baskets) and keep them outside. They get morning sun but are shaded by noon. I used coconut husk around the basket then bark and moss on the surface. It always surprises me when they blooms usually within a year with a different array of colors. I don’t have any problem leaving them outside. But I give ice cubes when we’re in the 90’s. It’s always hot in South Texas. They’re hanging in a colored tomato cages. I haven’t repotted since. They’re inside during winter. Your post really helps. It’s greatly appreciated. Thank you.

      Rita,
      Thanks for sharing! Sounds like your orchids are doing great! Rescuing orchids is so rewarding, and it’s fun to see what colors the flowers will be when they bloom. I would love it if you sent me a picture of your orchid setup. If you have a minute, email me a photo: anna@orchidbliss.com.
      Thanks again for sharing,
      Anna
