Succulent Fertilizer – Which, When and How Often

Best Fertilizer for Succulents

One of the (many) reasons people love succulents is that they are so easy to grow with little care. But low care is not the same as no care. Although these charmers survive with little water, succulents do need proper watering. And though they are adapted to nutritionally lean soil, succulents do appreciate the right amount of fertilizer at the right times. Their exceptional adaptation to low nutrients means it can be easy to over-do it when it is time to feed. With the right nutritional support, your succulents will thrive! Let’s look at some options for succulent fertilizer and how best to use them.

Do Succulents Need Fertilizer?

Do succulents need fertilizer? Strictly speaking, no. Your succulents will certainly survive without you feeding them. But the right fertilizer will provide a boost of nutrients that will make your succulents healthier with fuller, more abundant growth. With sufficient nutritional support, succulents grow more quickly, bloom more fully and have more perfect form. They are also better able to respond to environmental stresses. With a light fertilizing, your succulents will truly thrive.

Feeding Succulents

Feeding succulents is as much about what not to do as it is about doing it right. Some chemical plant food is likely to burn succulents or even cause scarred or misshapen leaves, unless it is diluted to a quarter-half strength of the general recommended dosage. I prefer to go with a mild organic solution that is rich in micronutrients. An organic fertilizer supplies your succulents with the broad array and low levels of nutrients they need to thrive, while feeding the soil they grow in.


I fertilize all of my succulents, those in the ground and those in containers. I’ll show you my favorite succulent fertilizer treatments.

Benefits of Manure for the Garden

Nature is so clever to have the manure of grazers replenish the land where they drop it.  Well composted manure from a variety of grazing animals like cows, horses, sheep and chickens has long been recognized as a boon to garden soil. It is rich in an array of micronutrients and minerals. These feed the microorganisms in the soil that are so critical to the health of your plants. Manure increases the soil’s aeration and is a premium soil conditioner. It also makes the soil’s carbon content more accessible to the plant. It is a wonderful amendment that nourishes and revitalizes the soil and promotes larger and lusher plant growth.

Manure Tea for Succulent Fertilizer

If you want all the farm-bred benefits of organic cow manure for your succulents and plants, but with none of the fuss, mess or smell – this is the product for you. Authentic Haven Brand Manure Tea is well-composted manure that will never burn your plants, and that your hands will never touch! Used as a tea, it is an accessible supply of nutrients for your plants that gives fast acting results. I use it to soak my bare root roses and fruit trees for 1-2 days before planting them. It gives them a terrific nutritional boost and gets them off to a strong start. And my succulents love it!

I put a tea bag into a 5-gallon bucket, and set it in the sun for 24-36 hours. The water turns a rich brown-tinted golden color. I water most of my plants and succulents with that solution. I water when the soil is dry, in place of a regular watering. The tea bag can then be reused for another tea batch, though I steep it for 3 days on the second use. For some plants, like tomatoes, I dilute it 1:1 with fresh water, and use it every other time I water the plant.



Most of my plants get manure tea once each month. For my succulents, I plan on three regular feedings each year with the manure tea. Once in the early spring to get them ready for the growing season. Once in June, before the high heat of summer sets in. Then again in late summer / early autumn after the heat of summer has broken. For those gardening in cold winter climates, I recommend feeding your in-ground sempervivum and cold-tolerant sedums and opuntia in early autumn, to give them a great jump on the cold season to come.

The Benefits of Worm Castings in Your Garden

There is one other organic fertilizer I use for my succulents – and all of my plants get it. Worm castings are the waste product of earthworms – essentially worm manure. It is an invaluable soil amendment for gardeners. Everything you grow, from vegetables to roses to succulents, benefits from an application of worm castings. The benefits include:

  • Worm castings are rich in over 60 different micronutrients and minerals, including potassium, carbon, iron, copper, zinc, magnesium and calcium in addition to nitrogen, phosphate and potash.
  • The use of worm castings will balance out high or low soil ph, allowing the plants’ roots to take up the nutrients they need.
  • It is rich in humus and improves the aeration of the soil and the nutrition of beneficial micro-organisms, boosting the health of the plants.
  • Worm castings fix heavy metals in the soil, preventing the plant from absorbing too much of these compounds, which could otherwise prove toxic.
  • Worm castings contain enzymes that will repel many pests, including whiteflies, mealybugs and aphids.
Worm Castings for Succulent Fertilizer

Like the manure tea, worm castings are rich in micronutrients and results in stronger, healthier plants. But there is an added benefit I just love, especially for a succulent fertilizer. Worm castings are rich in an enzyme called chitinase. This enzyme breaks down the chitin in an insect’s exoskeleton. As the succulent takes in the chitinase through its roots and distributes it throughout the plant, it becomes quite resistant to mealybugs, whiteflies, aphids and other leaf-sucking pests. They sense the presence of the chitinase and avoid feeding on it, to avoid their own damage and death. Yet beneficial insects like ladybugs are not harmed, because they do not feed on the plant. My favorite pest control is one that prevents the problem!


When I plant my succulents, either in the ground or in a container, I add worm castings directly to the soil, and mix it in. In a small pot, I add a couple tablespoons of the worm castings. For a large pot or for a plant in the ground, I add a couple handfuls of the worm castings. You can also make a tea of worm castings to use as a soil drench or as a foliar spray. This is a great option for both feeding your plant and fighting an infestation of mealybugs or whiteflies.

Hello Succulents Worm Casting Tea

Hello Succulents vermicompost tea is a handy, spray pump bottle of organically grown worm casting tea. Like the manure tea above, this is a fantastic succulent fertilizer that provides the benefits of organic feeding with no mess. Simply spray this superfood onto the soil around your plants to feed your succulents. Spray directly on the leaves as a foliar feeding, or to treat whiteflies or mealybugs. I use Hello Succulents sprayed on the foliage of all my succulents at least once a year, and especially for those that I plant close together in containers, where it is difficult to apply the spray to the soil. The results are happy, healthy succulents highly resistant to pests. Beautiful!


How often should you fertilize your succulents? You can use a succulent fertilizer as often as once each month. Commercial growers feed this often, to ensure the largest, lushest plants in the shortest period of time. However, any plant grown in consistently perfect conditions tends to be less capable of surviving when conditions are less than perfect. In the gardening trade, this is known as growing plants “soft”. This is why so often a beautiful plant from the nursery just doesn’t truly thrive in your garden.

Environmental stresses are a part of life. While I do feed my succulents, I do not baby them. I want them fully capable of surviving the stress that comes their way, either from crazy heat waves, a clumsy cat knocking over a container or my own imperfect care. That is why I grow my succulents “hard”, with far fewer applications of organic fertilizer than they might ideally like.

Choose Organic Succulent Fertilizer Carefully

The saying goes, “you are what you eat”. This is just as true for cows and worms – and their manure – as it is for us. I prefer to know that the cows and worms that provide manure for my garden were raised organically, free of pesticides, herbicides and hormones. If this is important to you, read the labels carefully to verify the conditions under which the manure was developed and harvested. Then you will have a succulent fertilizer perfect for your needs. You can count on the Haven Brand Manure Tea and Hello Succulents.


Should You Use Succulent Fertilizer Indoors?

Your indoor succulents will appreciate a feeding of manure tea or worm castings, too, responding with more vigorous growth. But consider your plant and its growing environment before you feed them. If you have abundant light, by all means, give your indoor succulents a boost with the organic tea. However, if your plants are etiolated – stretching as a result of low light, remember that this organic food will spur faster growth. It will not compensate for the low light but will encourage more stretching, faster. If you plan to give your indoor succulents a summer vacation in bright, indirect light outdoors, then definitely give them a good drink of manure tea or worm castings a couple of days before you move them.

  1. This is a wonderful article. Thank you so much. My succulents collection is growing and I want to keep them all happy!
    I have been seeing worm castings all over lately and didn’t know what it was. This was very helpful.

    1. Hi Cindy,
      I am so glad this was helpful!
      Worm castings are a boon to the garden for all types of plants. Many of my vegetables and all fruit trees get an inch layer of worm castings as a top dressing to the soil. With every watering, nutrients and pest resistance are carried down through the soil and to the roots! 🙂
      Have fun with your succulents, and let me know if you have any questions!

  2. I enjoy reading your articles on cultivating succulents. I live in South Africa and need advice re watering of Lithops. Some aricles say they should not be watered during the summertime, i.e. September to April! As that is our rainy season and teperatures of 35 to 40 degrees Celsius occur, I can hardly believe any plant can survive without water.

    1. Hi Trynie,
      The reason lithops can go for several months at a time in the heat of summer without water, is because they go dormant at this period of time. When a plant is dormant, its normal biological activities are greatly reduced. In the case of lithops, they are dormant in summer to lessen the plant’s need for the scarcest resource in its native habitat – water. The thick, fleshy leaves have lots of moisture and nutrients stored for the plant to draw upon in need. Please take care to protect your lithops from rainfall during your summer months. When autumn returns, your lithops will emerge from dormancy and renew active growth. That is the time to renew your watering.
      Enjoy!
