Euphorbia is a genus of flowering plants belonging to the family Euphorbiaceae, often called spurges. It is a succulent that can grow to be a large shrub or small tree. It can also take on the form of an upright or trailing plant depending on how it’s grown and what type you decide to purchase.

These plants are native to Africa, Madagascar, and the Arabian Peninsula in southern Asia. The name is derived from Greek words meaning “well-being”. There are around 800 different species of euphorbia growing throughout the world today.

So, how do you grow Euphorbia? For better results, start with a plant that has already been growing for some time so as not to shock the roots. Euphorbias are very tolerant of cold temperatures, drought, and low-light conditions which makes them ideal plants when trying to grow indoors or outside in colder climates.

If you’re planting your euphorbia outdoors then choose an area that gets at least four hours of direct sunlight each day. For those looking to grow indoors, it’s best to place the plant near a window with lots of natural light rather than artificial light. 

Euphorbias are relatively pest-resistant plants and grow quickly which makes them an ideal addition for home gardens but they do have one major drawback. They’re poisonous to animals, humans and birds so use caution when handling this plant or any part of it at all times.

 If you’re looking for some Euphorbia growing tips, then this article is perfect for you. We’ll go over soil preparation, watering frequency, sunlight requirements, and more in-depth topics like pruning and propagating your plants.

Common characteristics and features of the Euphorbia

-Euphorbia plants are a succulent that can grow to be either large shrubs or small trees

-Euphorbias usually have spiny stems, branches, and leaves but not always which is why it’s so important to identify the species before planting

-There are around 800 different Euphorbia species in existence today with about 60 of them being native to the U.S

-Euphorbia plants are able to grow in a variety of conditions with low water needs, cold tolerant, drought-resistant, and ideal for beginners

-Many Euphoria species have leaves that can be either green or red as well as other colors which is why they’re often planted close together for their varied color combinations

-Euphorbia plants are poisonous to animals, humans, and birds

-Euphorbias grow relatively fast so they’re a good choice for home gardens but can be pruned to produce new cuttings that will then root in water or even the soil if conditions are right.

Propagation for Euphorbia plants

Euphorbia can be propagated in the following ways:

1. Cuttings


-Take a cutting from the plant and make sure that it has at least two sets of leaves on it

-If you’re planting indoors, then place your cuttings in a glass or jar filled with water. Make sure to change out the water every few days until roots develop

-For outside plants, take your potting soil and poke a hole about an inch deep in it

-Insert your cutting and make sure that the leaves are at least one to two inches underground level. Cover up with soil and gently pat down until there are no air pockets left

-Water well before placing outdoors or bringing inside for a few weeks of growth

Note: This method is perfect for propagating new plants or cuttings but will not work for creating a mature tree

-A hardwood cutting is the best way to produce healthy and strong euphorbia trees. This method requires more time as it takes about one year before the plant can be planted outdoors


-Take your Euphorbia branch and remove the leaves, making sure that there is at least one set of leaves on it

-Cut your branch into two-inch segments and place it in water. Make sure to change out the water every few days until roots develop

-After a few weeks you’ll notice new growth coming from where you cut off your branches which is when you can then place it in potting soil. Ensure that the cut end is at least one inch below ground level and cover up with soil

-Water well before placing outdoors or bringing inside for a few weeks of growth

Note: This method will not work on branches without leaves as they won’t be able to absorb water needed for new root development

2. Air layering


-Take a plant cutting that is about six to eight inches long and make sure it has two or more sets of leaves on it. Cut off the bottom portion and place in water with new growth coming from where you cut off your branch for rooting purposes

-You’ll then need to take some soil from your desired location and wrap the plant cutting with it. Make sure to leave about two inches from ground level for roots

-After a few weeks new growth will come out of where you cut off your branch which is when you can then place it in potting soil, just like before. Ensure that the bottom end of your plant is at least one inch below ground level and cover up with soil

-Water well before placing outdoors or bringing inside for a few weeks of growth

Note: Air layering is the process where you don’t need to remove any leaves from your plant but still requires that it has two sets of leaves. This method also takes longer than cuttings because it’s not until after one year that you can place the plant in your garden.

3. Division


-Identify which Euphorbia plant you want to divide and gently pull it apart with a spade or your hand. Be careful not to damage the roots while doing this as they can be easily damaged if pulled too hard

-Take some potting soil from your desired location and place it on top of the roots. Make sure that the top portion is covered by about an inch of soil

-Water well before bringing inside or placing in your garden for a few weeks to allow new roots to develop

Note: This method will only be successful if you’re dividing mature plants with at least one year’s worth of growth on them. It also takes longer than cuttings or air layering because it’s not until after one year that you can place the plant in your garden.

Watering  guide

Euphorbia plants need to be watered every week for at least an hour to ensure they don’t dry out. The watering time can be extended to every two weeks if the plants are indoors and do not receive a lot of natural light from outside. In case of drought, it is important to water the plants twice a week.

This will not only ensure that the plants stay looking healthy but it will also save your pot from cracking. Nevertheless, you may water your plant any time to notice the leaves are curling up and turning to a yellow or brown color. This means that it has been deprived of water for too long

Water your euphorbia once a week for at least an hour to prevent it from dehydrating.

If you want to make sure your plant is getting enough water, the best way to do so is by using a soil meter. Simply stick one end into the potting soil until it hits the top, then wait a few seconds and look at the readings. If they’re not within an ideal range of 80-100% you’ll need to water your plant more often or invest in a new pot with better drainage

It’s worth noting that when watering it is best to use room temperature (cold) water rather than cold. This will prevent the soil from contracting around the roots and shrinking.

Euphorbia Fertilization Guide

Euphorbia needs to be fertilized every two weeks for understory plants that are outdoors and four times a year for indoor plants. The fertilizer composition is different depending on the type of soil you are using. Understory plants will require a fertilizer that has both nitrogen and phosphorous, while indoor plants only need fertilizers with nitrogen or phosphor.

Ideally, you should fertilize your euphorbia every two weeks.

If you would like to use organic fertilizer, try using compost tea or fish emulsion diluted at half strength. This ensures that you are feeding the soil with a nutritious liquid.

For synthetic options, look into Miracle-Gro which is known to work well with this plant.

Euphorbia Light and temperature requirements

Euphorbia plants will require plenty of light and different temperature requirements depending on their location. Understory plants need at least six hours of sunlight a day, while indoor plants should be set in an area that gets three to four hours of natural or artificial light daily. In case of cold climates, make sure that your plants are stored in a place where they can get plenty of sunlight.

Euphorbia requires at least 6 hours of sunlight daily.

In terms of temperature requirements, both understory and indoor plants need to be kept at room temperature for the most part but should not exceed 75°F (24°C). If you want to keep them alive during the summer months without sun but it’s important to note that they don’t do well in humid environments. Euphorbia prefers natural light to artificial light and should not be placed in dark areas.

Euphorbia Pruning guide

Euphorbia plants grow in a wild and natural pattern that can make it difficult for gardeners to prune the plants. Do not be afraid of cutting off some branches, as this will help them to look tidy and create desired space. Pruning also helps get ideal cuttings for propagation.

Pruning your euphorbia will make the plant look much tidier.

If you’re pruning your plants for the first time, it’s best to use a sharp pair of scissors or garden shears. You can cut off any branches that look unhealthy and make sure they are at least two inches away from the plant. It is important not to leave too many stubs behind because these will grow into new shoots.

Do not prune your plants in the winter because it is important to do so when they are dormant and would prefer you not to mess with them during this time. Prune during spring or fall months when they are actively growing. If you notice that some branches have grown low enough, now might be a good time to trim them off and avoid future accidents. 

Euphorbia Pests and Diseases Guide

In the event that your plant becomes infected by pests or has a disease, it is important to act quickly before they spread. Insects like aphids can cause yellow leaves, brown spots, wilting branches, stunted growth, and leaf drop while fungus diseases can cause a plant to turn brown and die.

To get rid of bugs you may use insecticide diluted with water, which should be sprayed onto the plant’s foliage one time every two weeks. To treat fungus it is best to mix up some baking soda (half cup) in a gallon of water then spray over your plant’s leaves as needed.

If you are unsure of the cause, it is best to call an expert who can help diagnose your plant’s specific problem and provide a solution for getting rid of them.


Aphids are one type of insect that can infect plants like Euphorbia with yellow leaves and wilting branches. To get rid of these insects you will need to use insecticide diluted with water and sprayed onto the plant’s foliage every two weeks.

Fungus Disease

Fungus disease is another type of problem that can affect Euphorbias, causing them to turn brown or die if left untreated. The best way to treat this is by mixing up some baking soda in a gallon of water then spraying it onto the plant leaves as needed.

Wilting branches

Wilted Branches can be caused by aphids or fungus diseases, both of which need to be treated with insecticide diluted with water and sprayed every two weeks.

Stunted growth

Stunted Growth can be caused by aphids, fungus diseases, or dry weather. To prevent stunted growth it is recommended to use organic fertilizers that have nitrogen as well as phosphorous.

Pests that like to attack Euphorbias are mostly found on the top of the plant or in the leaf axils. If you notice this happening then it is best to use a product with Neem oil on it, which can be bought at any garden center. Alternatively, you can use the natural remedy of baking soda to get rid of them.
