How To Root Pepper Cuttings In Water?

The method of rooting pepper cuttings in water is very simple. You need to take your plant out of its pot and place it into a bowl filled with cool (not hot) tap water. Then you put the plant in a dark room and leave it there until the water temperature reaches 70°F or lower. When the temperature drops to around 50°F, you are ready to begin rooting your new pepperlings!

If you want to do it right away, you can use a bottle cap or even a paper clip. If you have any doubts about whether the water will reach the bottom of the container, just submerge your plant in cold water first. Once submerged, you can continue with rooting.

You might think that using plastic containers would be better than glass ones because they are less likely to break when dropping something heavy into them. However, if you follow these instructions exactly, you won’t get any plastic breaking problems.

In fact, if you keep the temperature at 70°F for too long, the roots may die off completely. So don’t let it go above 65°F for too long either! If your water doesn’t reach the bottom of the container within 24 hours after placing your plant in it, then try again tomorrow. Otherwise use paper clips to pick up the container and drop it a couple of times. If you don’t have the luxury of waiting for 24 hours, then just trust that it works anyway!

Just make sure that you keep the plants in water until new roots appear. If your water goes cloudy, this is normal. In fact, this is an indication that the plant is absorbing all the nutrients it needs from the water. The plants should be ready to be potted in soil in around two weeks.

In my experience, I found that the paper clip thing is a lot more reliable than just guessing how long to wait. And I trust that this is the best way to go as well, because it has been tested and refined by many other people.

In fact, I’ve seen other people try to complicate matters by doing things like attaching strings to the container or using a big bucket of water. Don’t bother with these things. It’s a waste of time and not nearly as reliable as the method listed here.

For this technique to be successful, you need to keep the water at the correct temperature for long enough. For most people, this means placing the container somewhere dark like a cupboard or at the back of a closet. If the water gets too hot then drain some out and place the container in a cool area until it cools down again.

What if you don’t have anywhere dark to leave it?

A lot of people will solve this problem by placing the container somewhere like a garage or basement. Again, make sure the water temperature doesn’t get too hot for too long!

Using White Vinegar To Help Prevent Mold Growth

If your plants are prone to developing mold, then add some white vinegar to the water. This should prevent the formation of any fungus.

Using Ice Cubes To Lower Water Temperature

If you happen to have a lot of ice cubes, you can use these to lower the temperature of the water quickly. However, make sure you don’t use so many that your plant floats to the top.

Another option is placing the container in a larger container filled with water. This should cool down the water slowly over time, which is exactly what you want!

After The First Week…

You need to remove the container from whatever water source you’ve been using and change about 1/5th of the water for fresh water. Don’t place it somewhere hot or in direct sunlight, as this could dry out the soil and kill off your plants.

After another week, you can change another 1/5th of the water and so on until you’re left with pure water without much nutrients in it. After another week, you can throw away the old water and just refill the container with fresh water.

Now your plant will be used to living in water and should be fine for a long time, as long as you keep the soil damp (but not too damp).

If you place the plant outside during the summer, then it might be best to leave the container in a shaded area and only give it water once every couple of days. Leaves will go brown and fall off naturally as this happens, but they will grow back over time.

What About Air?

Some plants, such as Pothos, can survive for long periods without soil, as they get all their nutrients and moisture from the air. In fact, you can even place them in water and they’ll still be fine!

If You Have Money…

If you’re really struggling to keep your plants alive, it might be best to buy a plant that’s pre-grown and ready to transplant straight into the soil.

However, before going out and buying anything, ask family members if they have any spare plants they could give you. Chances are you’ll find someone has a few that are just sitting around gathering dust!


If you want to make sure your plants have enough light, you should place them somewhere they’ll get natural sunlight during the day such as near a window. However, only do this if you can keep an eye on the plants yourself as small children and animals may walk away with them!
