What is a String of Beans?

Scientific name: Senecio Rowleyanus
AKA: String of Beans

As mentioned above, a string of beans belongs to the succulent family. It gets it’s name from the small bean like leaves which grow on a trailing stem which can grow usually between 60-90 cm, literally giving it the look of a string of beans.

They’re often potted in hanging pots with the ultimate look in mind being a cascading waterfall of these odd shaped, specialised leaves which are extremely different to a lot of other hanging plants. They can also be kept in a normal pot and allowed to spill over the sides, this is also a desired look.

A string of beans can often be seen as a beginner plant, however there is always a slight tendency in new growers to overwater this plant, often it is forgotten that it is a succulent and doesn’t need quite as much as others would. With this guide however, you will be able to avoid all of those simple mistakes and have a beautiful string of beans to show for it!

What lighting does a String of Beans need?

A string of beans loves bright, indirect light. This is often found in a placement near a window but not directly next to it. When finding a placement for your string of beans, be mindful that they do get sunburned easily, so if you live in a hot climate and have extended hours of bright, strong sunlight, it may be best to places this plant at leas 5-10 feet away from the window. This will ensure that it doesn’t get sunburned and will grow at an optimal rate.

If you live in a darker area or your home just doesn’t get enough sunlight, a grow light might be an option for you. If you’re going to use a grow light to supplement your string of beans natural sunlight then it is recommended to place it 6-12 inches away and be running for 12-16 hours a day.

What kind of soil does a String of Beans need?

Again, keeping in mind that this is a succulent, it is important to give your string of beans a very well draining soil. A succulent specific soil is recommended, especially if you’re just starting out, alternatively, any sandy soil should also provide adequate drainage.

The type of pot that you plant your string of beans in is also extremely important, of course we need something which will drain very well. For this, either a terracotta or unglazed ceramic pot is recommended. These two types of pots provide excellent drainage and will keep your plants happy.
The size of the pot you use is also incredibly important, string of beans have rather shallow roots, meaning that a pot which is too large is completely unnecessary and can also lead to issues with overwatering.

It is also important to ensure that not too many beans are resting on damp soil, this can lead to rot. Make sure that the soil is near the top of the pot, this will let the plant fill the pot, give it adequate aeration and decrease the amount of leaves in contact with damp soil.

How often should you water a String of Beans?

Generally it is ideal to water your string of beans once every two weeks in the summer and around once a month in the winter. This is obviously depended on the climate you live in, hotter, drier climates will need more watering whilst cooler, more humid climates will require less.

These plants are very susceptible to overwatering, so it would be smart to always check the soil before watering, if the top inch or two of soil is dry, then go ahead and water. If it is still moist however, it means you should wait a few more days to prevent overwatering.

When watering your string of beans, put the pot in a sink or bathtub and turn the tap on for 10-15 seconds or until whenever you see water coming out of the drainage holes, you can leave it there and when no more excess water comes out, put it back in its spot.

They are very beginner friendly in this aspect.

How much fertilizer does a String of Beans need?

Like most other succulents, a string of beans does not need too much fertilizer and if you do use too much or use it too often, it can kill the plant.

It is, in my opinion, better to keep your plant in a smaller pot than move it to a bigger one in most occasions and this is for two reasons. The first of which is that it simply looks better, more full and extravagant. The second reason is that it is harder to make a watering mistake. It is much better to underwater a string of beans than to overwater it and by keeping it in a smaller pot, you’re decreasing the chances of it being overwatered.
