CARE Terrarium

The right light is essential for the health of the plants. Therefore, place your terrarium in a place with sufficient daylight, but never in direct sunlight or near other heat sources such as a central heating system or bright spots. Good to know: windows on the north often provide too little light. The terrarium is only suitable for indoor use and the best temperature is between 15 and 25°C.

Our terrariums have their own mini ecosystem and therefore require little to no maintenance. We do recommend turning the ecosystem a quarter turn every two weeks, so that all plants receive even and sufficient light. With the right conditions, the plants can keep themselves alive for years.

A closed Growing Concept creates a microclimate itself through which the plants keep themselves alive by recycling the water in the glassware. Nevertheless, it can occur on average once every six months that it is necessary to give extra water. Take the soil as a guide to how moist it is in the pot. If the soil feels dry, you can water 5 to 10 cl, depending on the size of your Growing Concept.

An ecosystem has to acclimatize in the first few weeks. This can cause small white mold spots on the moss, branches, leaves or stones. Don't worry, you can easily remove them with a clean cloth or by cutting away the moldy leaves, stem and all. A biological equilibrium is created automatically.

A healthy ecosystem condenses on one side of the pot. Is the entire pot fogged and dripping? Then this is a sign that it is too hot and the system cannot get rid of this heat. In that case, open the jar for twelve hours. Does the problem persist? Then move the pot to another place in the house, for example the north side where it is less light and warm.

If one of the plants loses a leaf, it falls to the bottom, where it decays and is used again as food. A beautiful natural process. However, this also has a downside: the leaf decomposition process sometimes attracts tiny flies, better known as mourning flies. They lay eggs in the soil. Fortunately, there is something to be done about this: garden centers sell a biological control agent called 'steinernema feltiae', also known as nematodes. This comes in powder form, to which you add some water and then pour it over the soil.

In principle, this is not a problem. Sometimes one of the plants loses a dead leaf. That falls to the bottom, decays and is used as food again. If it bothers you, you can also cut brown leaves, stem and all.

We choose plants that grow relatively slowly and therefore do not require frequent pruning. Has your plant grown too big for the glassware? Then you can prune the plant to its original size. Trim the twigs just above a leaf base. Then leave the terrarium open for 24 hours, so that the plant(s) can heal properly.

Yes, the mushroom is a harmless type of fungus. You can safely let nature take its course. The mushrooms will not affect your ecosystem and the plants. If it bothers you, you can remove the mushroom.

The cushion moss that we use is particularly resilient, it does resemble a sponge. You can carefully remove it from the ecosystem and then place it in a container of water. Leave the moss for a few hours and it will regain its dark green color. Then squeeze the moss so that it is not too wet and put it back.



Our products are composed with great care and love in Haarlem. We work together with artisan and local makers and are closely involved in the production process.

We work with natural materials that we select with the greatest care for durability and longevity. Our plants come directly from the grower, the glassware is recycled and the woodwork for the accessories is handmade by a Haarlem company.

We work with the best growers in the Netherlands and Denmark with MPS certification. This is a quality mark in the field of sustainability. With this certificate, these growers meet requirements in areas such as traceability, the environment, crop protection products and recall procedures.

Nice that you are going to surprise someone with a Growing Concepts! Are you going to give the product later after receipt? Then we recommend that you take the plant(s) out of the box and the packaging, give them some water and store them in a bright place in the house until you hand over the gift. You can also choose to assemble the DIY package yourself and give it to the recipient as a gift already fully installed.

Our ecosystems are delivered as a complete Do It Yourself package. It contains everything you need and step-by-step instructions to get started. The contents of the package consists of stones, soil, moss and the plant(s).
