Can you grow plants in glass pots? Yes! Glass is making a big, sparkly comeback.
Seen as a zero-waste and pollutant-free alternative to plastic, glass vessels are back into our lives with more and more alternative applications beyond food storage. The trend also brought us a new diversity of glass container designs.
At the same time, plant and interior enthusiasts always look for new ways to display their beloved houseplants.
In that context, planting in a glass jar seems convenient, innovative, and straightforward.
However, you may also wonder if it’s the best idea for plants. After all, glass jars don’t have drainage holes. Also, you might have heard that plants don’t like their roots to get exposed to light.
Luckily, the plant world is so amazingly diverse that for some species, planting in glass pots is a valid option for the plants and onlookers to enjoy.
Let’s explore what plants can get planted in glass jars and how!
Can You Grow Plants In Glass Pots?
The good news is that yes! You can grow plants in glass pots – from good old-fashioned mason jars to specially designed glass planters and vases. However, there are some limitations regarding the plants you can grow. As well as certain precautions you must take to ensure your plants will remain healthy.
Another beautiful thing about glass containers is that you can use nearly any glass vessel – you only need to match the correct plant.
Closed vessels such as bottles, bowls, and vases for tabletop terrariums work best with moisture-loving plants. As for open glass containers, you can easily include plants that prefer drier conditions.
How to Grow Plants In Glass Pots
There are three main ways to use glass jars and other vessels for plant growth.
- As glass pots and planters, with plants put directly into a medium. Using glass pots to grow plants can take place as regular potting (with soil) or as a passive hydroponics system (with water and perhaps a hydroponic substrate).
- As glass terrariums
- For rooting cuttings, while certainly very functional, glass jars with rooting cuttings can also make an intriguing display.
However, there are some commonalities shared by all forms of glass-pot plant growing. We will take a glimpse at these before tackling the said three ways of glass container plant cultivation.
How to Grow Plants In Glass Pots – Step-By-Step Guide
Well, in the beginning, I promised there would be some easy steps to succeed with glass planters.
I can already see you getting discouraged by the length of these simple points!
However, don’t lose your patience just yet. With glass planters, the devil’s in the details. In general, using glass pots is indeed straightforward. But there are a few specifics we need to pay attention to and consider.
1. Glass pots lack drainage holes. Thus, except for rooting cuttings, we advise you to ensure proper drainage at the bottom of a glass pot. Add a suitable thick layer of non-degrading drainage material. Coarse gravel or clay pebbles to the bottom of the planter work perfectly.
1.1. You can also drill a hole in a glass jar, although this is tricky with many jars and glass containers.
1.2. Put the substrate on top of this layer! All the excess water from the substrate will drain into (well, duh!) the drainage layer.
3. The drainage layer needs to be thick enough so the rootzone can’t directly access the excessive water. Instead, the water will be pulled upwards by capillary forces when the substrate gets drier.
4. Be careful with watering. Since the water cannot escape the glass and there is no evaporation through pot walls, the plants will require less watering than in the case of regular pots. Too much water in these conditions definitively means the danger of root rot.
5. When it comes to lighting, glass planters are perfect for placing in a spot with indirect light, with brightness depending on the need of the chosen plants.
5.1. Exposing glass pots to too much light will lead to green algae proliferation, which means an unsightly slimy green layer on the inner side of your glass planter. Also, direct sunlight can overheat the glass planter and adversely affect the root system.
5.2. Covering your glass pot with a dark, non-transparent wrap or putting it in a second decorative pot will solve most of your problems regarding the unwanted light and the algae. Naturally, this solution will not work for people that want the glass to show due to its aesthetic value.
6. If you use glass containers for cuttings or to grow plants in water in a passive hydroponic-like system, you don’t need to take care of drainage and watering. However, all the other points about lighting and maintenance apply. Also, growing plants in the water will likely require you to monitor the mineral and nutrient levels if you want the plant to thrive for a long time.
7. Most glass pots require some maintenance and cleaning – periodic limescale and green algae removal.
8. Lastly, choosing the best plant species to grow in glass containers is essential for success. In general, seek plants that don’t grow large and are not sensitive to watering regiments and excessive moisture. Also, avoid drought-sensitive plants on the drier end of the spectrum! And for bonus points – try plants that are not prone to root rot. We think if you follow these tips when choosing a glass-container-destined plant, they will do well.
The exact species choice will depend on your glass planter’s particular style.
Read on to discover how to grow plants in glass terrariums, planters, and rooting containers and what species suit each application.
How to Grow Plants In Glass Terrariums
A terrarium is a small, confined plant ecosystem, a miniature glasshouse that fits the table in your living room. That is why terrariums often get created using glass jars, bottles, or other suitable glass formations.
From the very description, you can conclude how decorative a well-kept plant terrarium can be. They’re gorgeous!
However, take caution! Not all plants that look well in a glass terrarium are suitable for a glass terrarium.
The specific conditions of an enclosed mini-ecosystem – the limited space, low airflow, and (usually) high humidity. Not all plants can take these conditions. Few can last in a terrarium for a long time. Consequently, choosing the best terrarium plant species is crucial to the success of any terrarium project.
Proper watering is also critical. Terrariums are very sensitive to excessive water because of limited drainage and poor evaporation. Always add water carefully. If you’re noticing too many condensation drops on the sides of the terrarium, leave it open for a while (if the design allows it), so water would be able to evaporate.
When it comes to lighting, the need for glass terrariums to stay in a bright spot with indirect light is critical!
Why? Well, the drainage layer also serves as a humidity tray. Leaving a glass terrarium in warm, direct sunlight will increase evaporation to unwanted levels. And lead to a build-up of heat. All the humidity and hot air may steam the plants. That would be quite a waste – unless you have some baby spinach in there! (Lol.)

How to Grow Plants In Glass Planters
In this section, I’ll use the term glass planter quite liberally. A glass planter can stand for any glass jar, bottle, sphere, bowl, commercial planter, or any other glass vessel you’ll use as a plant pot. The rules, tips, and tricks are pretty much the same for all types of glass vessels – unless stated otherwise.
Glass planters can look very handsome, modern, and rustic simultaneously. They can fit into various interiors, from modern minimalist to lavish Victorian-style steampunk ones.
However, all glass planters have one common issue. Their bottoms lack drainage holes. While it is possible to add some yourself, it requires tools and skills that not all of us have.
As per our simple steps above, the issue is easy to fix. Add a suitable and thick layer of drainage material. Coarse gravel or clay pebbles on the bottom of the planter work nicely. And be very mindful about watering! Always try to get a sense of how saturated the soil is before adding more water.
How to Root Plants In Glass Containers
Many plant enthusiasts got experience doing this before it was a thing – rooting suitable plants in a glass jar or another container is a no-brainer.
You just put a cutting in a water-filled glass jar, place the glass jar in an indirectly lit spot – and wait. The glass transparency will let you see when the roots have started to grow, so you don’t even have to stress the cutting by picking it up to check.
Modern plant fads have also taken things to a new level! Nowadays, many look highly decorative. I love the spherical ones that bring that plant laboratory feeling to your tabletop.
Check out our species lists below to learn what plants can root in water. Some of them, like pothos or English ivy, can continue growing in water indefinitely. Others, like the African violet, need to be planted in the soil quickly after rooting if you want a healthy new growth.

With proper drainage and plant precautions we discussed, it’s easy to treat glass pots like any other planter. However, to err on the side of caution, pick plants that are tolerant of moisture, and need indirect light. In other words – choose plants that are low-maintenance in general. Avoid challenging and sensitive plants like Calatheas.
When planting succulents in glass pots, ensure a well-draining substrate, a good drainage layer, and ventilation. Not watering too much is understood.
