Sansevieria Silver Blue is one of the best choices for beginners and travelers. Very resilient and tolerable plant.


Sansevieria Silver Blue likes bright indirect light. This plant is very resilient and can live under moderate light as well. But, because of its slow growth rate, you may have better luck placing it in a bright area and pups will show up.

If your home doesn’t allow as much light to come in, try help your Sansevieria Silver Blue with a growlight. It might not seem like a big deal, but it makes all the difference.

Sansevieria Kirkii likes less water than other sansevierias. As a rule of thumb, you can think of the leaves, the juicier they are, the less water they require. You can water it once every two weeks in the summer and once a month during winter time. Check the soil every time you water, it should feel completely dry.

If you forget to water your Sansevieria Star Green Granite for a very long time, you’ll notice the leaves will start to wrinkle. The roots will suffer as well, they will become fragile and will break easily. It if comes to this point, water your plant and keep an eye on it for a while.

However, if your sansevieria is overwatered, this will cause root rot and mushy leaves. If you don’t notice these changes fast enough, you may lose the plant. I recommend removing all the mushy tissue. Clean your plant with hydrogen peroxide and place it in water to grow roots.

Average. Sansevieria Silver Blue is great with temperatures between 18-25°C. Anything above that is fine, but anything below must be avoided. If temperatures drop below 15°C, it can cause mushy leaves that will die off.


Sansevieria Silver Blue will choose lower humidity due to its succulent leaves. Too much water means greater chances for rotting. That’s why you don’t need to mist this plant. Place it a bit further away of any other plant with higher humidity requirement.


Sansevieria Silver Blue can be fed once a month during growing season. Since the growth rate is very slow, sometimes is tricky to know if the plant is growing. That’s why I recommend using less fertilizer than is mentioned on the packaging.

Usually, I use a fertilizer with a 10-10-10 or 20-20-20 NPK ratio. However, if your Sansevieria is lacking roots, you can switch to a 15-30-15 NPK ratio to help promote healthy roots. Alternate a normal fertilizer with one stronger in phosphorus and see if this makes a difference.


Sansevieria Silver Blue is not a fan of soggy soil, so I want to make sure our substrate is light. I use a mix containing cacti soil (maybe 40%), perlite (40%) and coco coir (20%). The purpose of a mix is to make sure the water will drain faster and the pH levels don’t go to extremes.

It is best not to use regular soil since it can get soggy really fast. And also, don’t use just peat moss since its pH is too acidic and your plant won’t thrive and will slowly degrade.

plastic versus terracotta

I’ve been growing Sansevieria Silver Blue in both plastic and terracotta and it does great in any pot. Whatever you choose, please make sure your pot has drainage holes, unless you are an advanced plant parent and you know what you’re doing.

Terracotta is great for aesthetics and plastic pots are good for clumsy people like me. Also, side note, check your soil a bit more often if you choose a terracotta pot. The water tends to evaporate quickly and you don’t want your plant to get too thirsty.

You’ll probably never going to repot your Sansevieria Silver Blue… unless you don’t like the pot.

Because of its slow growth, Sansevieria Star Green Granite can take good years to get bigger. But if it’s the happy case and the plant has an offset, you can separate it from the mother if it has a decent root system.

It is preferable to repot during warmer times when the roots can recover quickly from any breakage. Winter is associated with dormancy in plants, so the plant has a slight chance of encountering problems if it’s disturbed.

I’ve tried propagating Sansevieria Silver Blue from leaf cuttings. It is a veeery slow and painful process and it’s not 100% guaranteed. It will grow tiny pups from the main leaf but it could take more than a year.

I suggest propagating it by division. Wait for the plant to have offsets and separate them from the mother plant. It will also take time with this method, but the growth will be steadier.

Sansevieria Silver Blue rarely gets any pests. Maybe those little devils are intimidated by the fat strong leaves. I think the only problem you might face (if ever) could be scale or mealy bugs. Acting quick is best.


Keep away any cute pets from the Sansevieria Silver Blue. Unfortunately, the plant is not pet friendly.
