Euphorbia Care:
Some plants need to be divided or propagated every two to three years, preferably in the early fall or spring, even if they have a short lifespan.
After flowering is complete, many benefit from being severely pruned, at least by one-third. This prevents any free-seeders from taking over and promotes the growth of new, fresh foliage.
Trimming euphorbia:
- Early in the spring, remove any damaged stems to keep the plant neat and healthy.
- As soon as the euphorbia blooms, trim the stems at the base.
- Clip carefully, since new shoots may appear that you wish to preserve.

for the plants that are listed here. Some species only have root hardiness further north but are evergreen in southerly zones. Other varieties do well as annuals.
Exposure: Sun or Shade?
Although some euphorbias can take some partial shade, most euphorbias prefer the sun. those with dark purple or reddish coloring
If planted in full sun, the foliage’s coloration will be more dramatic. In fact, just a few species prefer at least dappled.
Others require part shade in the South’s blazing sunshine but can tolerate intense sun in the North, where they can thrive. One option that works well in shadow is Euphorbia amygdaloides var. robbiae.
Soil:

What is the ideal location to plant euphorbias?
In general, euphorbias need a sunny location and rich, well-drained soil. Light types, meanwhile, can tolerate some shade and do well as ground cover around shrubs and trees.
How to plant euphorbias
Dig a deep hole when planting euphorbias that have been cultivated in pots and fill it with compost or leaf mould. Euphorbia should be planted firmly, then it should be watered well and mulched to keep moisture in and weeds out.
Here, Monty Don proposes two exceptional euphorbia species and provides planting instructions. Additionally, he offers advice on how to grow euphorbias from cuttings.
How to care for euphorbias
As long as the growing environment is favorable, euphorbias don’t need feeding or special care. After the blooms have faded, blooming stems should be pruned. However, gloves must always be used when working with euphorbias because their milky sap is hazardous if consumed and irritates the skin and eyes.
How to propagate euphorbias
Euphorbias can be grown by taking springtime cuttings. Wear gloves to protect your hands from the sap.

How much light is required for euphorbias?
Have a space in your home that receives a lot of light and begs for a plant? With the right care and attention, columnar euphorbia, which are intricate, sculptural succulents, will thrive inside. Continue reading for information on growing euphorbia as indoor plants as well as other fascinating facts about this beautiful plant. So come choose your favorite euphorbia at Flora Grubb Gardens, our store in San Francisco!
Let’s first address the biggest issue in the room: euphorbia are not cactus!
Despite having a similar appearance, cactus and columnar euphorbia are separate plants. You may observe the cactus’ rigid, upright trunk and arms if you look at a Saguaro. It grows in the desert and has spikes to protect itself from predators. Then take a look at a candelabra tree, which is a kind of euphorbia and has arms that are spiky for defense. In the desert, candelabra trees can also be found. What makes a difference, then? Contrary to popular belief, there are no cacti outside of the “New World.” Surely Africa has cacti, right? True, there are no cacti in Africa.
Understanding convergent evolution, which is described as “the process by which creatures that are not closely related independently evolve identical features as a result of needing to adapt to comparable habitats or ecological niches,” is necessary to reconcile this finding. In summary, because they were compelled to evolve in the same manner and under comparable circumstances, cactus and euphorbia are almost identical. Because this is an effective method for storing water, they are columnar. Spikes are used to protect that water. Despite having a similar appearance, they are totally unrelated despite having diverged over vast distances.
How do we tell the difference, then? The key differentiator is the flowers. Cactus blossoms are enormous, delicate, and frequently vividly colored. They are frequently pollinated by birds or bats. Fly pollination is common for euphorbia blooms, which are tiny, often green, and somewhat unimpressive. Whereas at first glance the spikes appear to be similar, closer examination reveals that euphorbia has thorns while cactus has spines (a modified leaf) (a modified stem). The majority of euphorbia have a toxic latex sap to aid in their defense, which is another distinct feature.
Columnar Euphorbia thrive well indoors when planted in a cactus mix that drains quickly. Here are some tips for taking care of them at home:
Euphorbias are warm-blooded plants, therefore south or west-facing windows inside—where the plant receives four or more hours of direct sunlight daily—are ideal, though they can also grow in extremely intense indirect light. If placed within 18 inches of a window, they could burn because their skin is more sensitive than cactus. To avoid this, arrange them so that they are angled toward the window. Make sure the plant has adequate drainage and is kept as warm as you can if you are growing it in bright indirect light.
Since these plants grow throughout the summer, water should be progressively increased through late spring and into the season when they can experience dryness without becoming completely parched. This indicates that the soil does not feel damp or chalky or cracked throughout the entire container. During this time, don’t leave them to sit about completely dry; shriveling is a sign that they haven’t received enough water. Although fertilizer is typically not necessary, you can use an all-purpose fertilizer in the summer at 1/4 strength.
During the fall, water should be gradually reduced. Euphorbia naturally receive relatively little winter precipitation. They should become completely dry between waterings over the winter. Make sure to let your euphorbia stand in a saucer of water until it has completely absorbed the water because it can be difficult to rehydrate a completely dry plant (as it is like a dry sponge, where water will just run off). Until there is standing water in the saucer that isn’t being absorbed, keep adding water and letting the plant sucking it out. The surplus water can then be emptied out of the saucer or removed by placing a towel, sponge, or turkey baster within the saucer to absorb it. Never leave columnar euphorbia submerged for longer than 12 hours.
Brown spots are the most typical problem with these columnar euphorbia. They may be corking if they are light brown and hard like a scab, which is the normal process of a plant aging. Consider corking as a tree’s smooth, green bark turning woody over time. Relax, this is very normal.
However, rot is present if the brown spots are deeper and mushy. The plant needs to have the rot surgically removed since it will spread and kill it. The more likely it is that you can rescue your plant, the earlier you catch rot. Three situations are possible here:
Dig down to healthy, vigorous tissue to treat a small area of rot, then let the plant repair by developing a scab.
You must remove the top, clear the rot from the top and bottom back to healthy, lively tissue, and then re-root the top if it has ringed the column halfway up. Replant the top in extremely fast-draining soil (half pumice or lava rock and half cactus mix) and set it in a warm, sunny location out of direct sunlight after allowing it to scab over for two to three weeks. If you have it, rooting hormone is also helpful for this. For re-rooting, cement or tile flooring work well because they carry heat to the plant; but, if you have a heat mat, you can use that as well. Set it to 72 degrees Fahrenheit. In this case, the top of the plant will produce a new plant, and the bottom plant will continue to develop and produce new heads. (You would also propagate the plant in this manner, typically in the late spring when it is actively growing.)
If the column’s base begins to deteriorate and spiral around it, you should discard the bottom and propagate the top. You may recall that we mentioned the plant’s latex sap is poisonous. Use gloves and avoid getting sap in your eyes while doing this because it is a serious skin and eye irritant.
Other typical issues with euphorbia planted indoors typically result from the plants being grown in chilly environments with little sunlight. Summertime underwatering of plants causes problems, but even a small amount of wintertime overwatering can be disastrous. Another typical error is to not water until the soil is completely saturated.
Euphorbia leucodendron and Euphorbia tirucalli ‘Sticks on Fire’ (also known as pencil cactus), two non-columnar euphorbias with lovely forking shapes that resemble aquatic flora almost as much as possible, may both be grown indoors. These require a lot of light to develop as houseplants and can even grow in bright, direct sunlight beside a window, just like the columnar euphorbia. (Not a good option for houses with pets due to the previously mentioned toxic sap!)
These incredible plants may, of course, also be cultivated outside in a temperate region like the Bay Area, even flourishing in the foggy streets of San Francisco. These euphorbia prefer a warm, protected location with plenty of sunlight and good drainage. They enjoy being next to radiant south- or west-facing walls or fences as well as slopes where water can drain off. Since they are summer growers, they will require more water during this dry period. However, if you want to fertilize, use an all-purpose fertilizer sprayed at 1/4 strength as they are typically not hungry. They frequently fail in clay soil, partial sunlight, or areas that receive an excessive amount of winter precipitation (in addition to our natural rainfall). Clay soil can benefit from mounding.
How frequently do I need to water my euphorbia?
Every residence near a Joshua tree has a Euphorbia Ingens. It is known as the “cowboy cactus” and “good luck cactus,” and believe it or not, with the appropriate lighting, they are quite simple and straightforward to maintain. This instantly transforms any space into the boho paradise of your dreams when you throw it in. Euphorbia ingens are quite gorgeous!
Water: During the summer, water your euphorbia every two weeks. However, make sure the soil is fully dry before each watering. Make sure the water drains through the grower’s nursery container before watering. The main enemy of its beauty is excessive watering, which causes root rot. From November to March, don’t water your plants. Just a tiny bit of water is required once a month, if you feel the need to water at all. Allow them to rest since they remain dormant throughout these months.
What does light love, do cacti? Find your new cactus companion a sunny spot where it can live happily ever after.
Moisture: Euphorbia Ingens will blend seamlessly into the typical home environment. They need misting since they prefer it dry.
Pet-safe: Handle your euphorbia with extreme caution. To protect yourself, it is advised to handle with gardening gloves. The white, very toxic African milk sap from the tree, which is present in even the tiniest amounts, can cause excruciating skin irritation. Keep your pets away from this plant!
Are euphorbias water-intensive plants?
Euphorbia is quite simple to maintain, much like every succulent. When taking care of succulents, there are certain common green thumb guidelines.
- Your succulent doesn’t require a lot of water. A plastic water dropper should be used to water your succulent every seven to ten days. Give your euphorbia between two and four full squeezes of the dropper after entirely filling it.
- Light and temperature: For the majority of succulents, indirect or direct light works best. Avoid leaving your succulent in the dark. Additionally, you should generally keep your succulents between 60 and 90 degrees. These plants are typically fairly resilient, but if you want them to flourish, try to keep them away from the harshest environments if you can.
- Repotting: Just moisten the soil your succulent is currently in, remove it with care, and repot it in a bigger container this time!
Here are some additional pointers and techniques for your euphorbia if you want to be more specific:
- Give your euphorbia well-drained soil. The roots of this plant cannot be exposed to water for an extended period of time.
- Euphorbia doesn’t require a lot of irrigation. Just water them when the soil is dry!
- Make sure the pot has drainage if your plant is housed in one.
Euphorbia has a plethora of characteristics that make it one of the most distinctive succulents to have. The pruning and propagation techniques used by euphorbia are yet another amazing quality. There is no plant that is simpler to take care of.
Use a clean, sharp knife to cut off the euphorbia’s branching portions while pruning it.
After pruning, feel free to spread your euphorbia! The process of propagation is used to grow additional instances of the same plant. If you decide to propagate your one euphorbia plant, it could yield numerous additional euphorbia plants.
Take the bits you cut off and replant the section that was chopped off to do this. Set aside that piece for a few days to dry. When the item is dry (but not completely dried out), place it in a vase of water. Let the roots develop in the water until they are totally exposed. On the sides or where the cut is made, new roots may grow. Simply replant your euphorbia in the ground or a pot. Keep an eye on your euphorbia as it multiplies!
Euphorbia is really simple to take care of. Watching your euphorbia flourish takes no time at all, just as with any other succulent. Simple and good care is all it takes! One of the simplest succulents to care for, the euphorbia just requires occasional pruning and repotting.
