Last year I wrote a post about growing succulents in glass jars. (See Post : Succulent Jars ) The majority of succulents should be grown outside (for most of the year) and receive some sunshine for part of the day. However, there are some succulents that will survive inside. They do look great but you need to consider the following if do not want the succulent to die.
This is the number 1 killer of succulents in terrariums or glass jars. They are either over watered or under watered. My first succulent terrarium plants died within a couple months – I rarely watered it and it did not receive enough light. I have learnt a lot since then. Here are a few tips:
- Do ‘not’ keep the soil damp/moist. The soil needs to be wet but then needs to dry out before watering again.
- Do ‘not’ spray succulents with a water bottle. The roots of the succulent need to receive water. Spraying does not give the succulent enough water.
- Do ‘not’ let water pool in the bottom of the jar/bowl. The roots of the plant will rot and the succulent will die if they sit in water. If you have put too much water in you can turn the jar/terrarium on the side and slowly tip out the excess.
Some succulents will let you know if they are not receiving enough water. Their roots will grow above the soil. So if you see a succulent with roots above the soil (as below) it means you need to ensure the roots below the soil are getting enough moisture.
Choose a well lit room that receives sun/bright light for most of the day. A sunny window sill is ideal. Ensure that as the sun gets lower in the sky in the winter that the window sill/room still gets the same amount of light. If the succulent does not get enough light it will start to stretch (etiolate) and will look elongated and lanky. If you have a heat wave and your succulents are receiving sun through a window then this could burn your succulent as the glass will intensify the sun and increase the amount of heat the succulent is receiving.
If you have your succulent in the bathroom be aware that some succulents do not like the humidity created by the shower and it will die. This happened to me with the succulent below.
Which succulents are the easiest to grow in glass jars/terrariums?
So which succulents are the easiest/hardiest to grow in jars….. and look good! My favourite is Echeveria Elegans. I have had a lot of success with these on a sunny window sill. Aloe succulents are also great indoors, they are shade lovers so being inside in a bright room is ideal for them. The one below has also coped with the humidity in my bathroom – so far. Jade is also a great succulent to grow in a jar. The ones below have even flowered. The only small problem would be that they would do so well that you will probably have to prune them fairly often.
I water my jars once a week in the summer and once a fortnight in the winter. I use a tablespoon measure and put one tablespoon on the small jars and two tablespoons on the larger ones.. The good thing about glass is that you can see the water wetting the soil and therefore see when it has dried out also you can see the roots in the soil.
So, yes you can grow succulents in jars but you need to be vigilant with regards to the water. Also be aware that the succulents will grow and could possibly outgrow the jar.
