Whether you are growing succulents & cacti indoors or outdoors, it’s really important to learn how to care for succulents and some very important Do’s and Don’ts. Let us find out how not to kill your succulents and how to keep them healthy and happy.
- MEANING OF SUCCULENT: Succulent means full of juice : juicy. So these are plants with fleshy tissues adapted to water storage. Some random examples of succulents are: Echeverias, Haworthias, Aeoniums, Gasteria, Sedums, donkey’s tail, All varieties of Kalanchoes, Jades and Crassulas, Aloe vera, All types of cactus like fairy castle cactus, Bunny ears cactus, Pincushion cactus, christmas cactus, and, the most beautiful Adeniums or Desert roses.
- SUNLIGHT: Most people think succulents are indoor plants. No doubt they can be grown indoors with proper care or that extra or special care. But succulents love full sunlight and do well with at least five or six hours of direct sun per day. This again depends on the type of succulent. And also, immature succulents or seedlings need lesser sun and have to be gradually introduced to sunlight like the Hardening Off procedure we follow for vegetable seedlings like 1-hour sun exposure for day 1, 2 hours for day, 3 hours for day 3 and so on. We will discuss more useful tips and tricks like how to avoid elongating and ugly growing succulents in the later part of this episode.
- WATERING: This is another very important factor for successful and healthy growth of succulents and cacti. The watering frequency depends on the season of the year. In spring to summer, the succulents grow to their full potential, like any other plant. And in winter season the growth is slowed down and many succulents go into a state of dormancy or inactivity, just like other plants. So, the watering requirement is drastically reduced in winter season. Now, lets talk about how to water, how much to water and how frequently to water. This is very important because overwatering can result in mold and rot and can kill the plant. Succulent and cacti are different from other plants with thick fleshy tissues like leaves or stems are adapted to water storage. So, a lot of water is already stored in these tissues and hence, the water requirement of these plants is very less compared to other plants.
While watering a succulent or a cactus, you need to stick to two rules to prevent over watering and rot. The first rule to follow is the Finger Dip method: Insert your finger to at least one inch into the soil to check the moisture. Water them only if soil is completely dry. You can also dip a moisture meter if you have. And second rule is to avoid water spillage over the fleshy leaves to prevent rot. For this you can use a watering can with a long nozzle to water over the soil and avoid water spillage over the leaves. Then thirdly water it thoroughly and deeply till the water flows out of the drain holes. Generally, in most tropical climates, watering weekly once or max twice a week is sufficient if kept in direct sun. - POTTING SOIL: This is another important factor for healthy succulent growth. Succulents and cacti need a soil mix that drains very quickly, so regular potting soil is not recommended to grow succulents. So, you need to add stuff that helps drain out water very quickly. One such succulent potting mix formula is:
30 to 40% of Garden Soil, 30 to 40% Sand, 10% to 20% pebbles or some small coarse rocks or pumice or perlite if available, 10 to 20% Compost like cowdung or vermicompost, Optionally you can add some 10% Charcoal – small pieces. Do not use cocopeat for succulents especially if you grow them indoors or keep them under indirect sunlight, because it can retain water and might result in mold and rot due to water retention.
- POT SIZE: Choosing the right sized container is also important for healthy growth of succuelnts and again this depends on the type of succulents you are growing. Most succulents have a shallow and delicate root system which do not need too deep containers and it can increase the risk of rot. For most succulents we recommend a wider shallow container for best results, because a wider container with enough space will help in propagation of succulents which produce offsets or babies from sides, which can be separated and grown as independent plants. Also make sure there are multiple drainage holes in the container you choose. You can also grow multiple succulents in a wide container. Make sure you give some spacing between each plant.
- FERTILIZERS: Succulents do not need much fertilizers, but you can give them light feedings like a teaspoon of vermicompost or decomposed cowdung once in 3 months and increase this during the active season – that’s the spring and summer season.
- PEST CONTROL: Mostly affected by mealybugs and the soil by the fungus gnats. You can spray neem oil once in about 15 days as preventive measure or weekly once to get rid of these if already infested. You can even water the succulent once with the same neem oil solution to get rid of fungus gnats. The dose os 5 to 10 ml neem oil per litre of water. The best alternative to kill fungus gnats is 250 ml hydrogen peroxide 3% per litre of water and water the soil.
- CLEANING SUCCULENTS: Wipe off the leaves and spines gently with a damp cloth to get rid of dust and this helps in better photosynthesis.
- REPOTTING: You have to take special care while repotting a succulent, because they are more prone to mold and rot after repotting. To avoid problems, always mix some antifungal powder or some neem cake powder into the potting mix during repotting.
- PROPAGATION: There are several, simple ways to propagate succulents. First method is: Growing from Cuttings: This is best applied in case the succulents have grown too leggy with elongated stems. This elongation of stem happens when there is little sunlight or if kept in indirect light. They elongate their stems for seeking sunlight. As a result they look ugly and take bad bends and turns. So, as discussed – keep them in full direct sun and make it a habit to rotate the containers once in a while to avoid bends and provide uniform sunlight. Well, coming back to propagation, Take the cuttings and leave it in air to dry for 2 days for callous formation – that’s something like wound healing and sealing to prevent rot. Then insert the cutting into a loose draining soil. Just keep the soil moist, do not water it too much. It should start rooting in 2 weeks.
The Second method is Propagating from Leaves: Yes, you can grow succulents from a single leaf. Just remove an actively growing healthy leaf from a mature succulent plant. Make sure you strip from the base, taking out the entire leaf. Leave this to air dry for 2 days and then just place it superficially over the soil. You should see a tiny plant popping out of this leaf with formation of tiny roots.
The Third Method is from Offsets or Babies, which are produced from the mother plant like aloe versa, haworthias and echeverias. Most of the succulents produce these babies which can be separated from the mother plant and planted independently.
The Fourth Method is growing from seeds: This is the slowest method to grow succulents. But if you have the time and patience, give it a try! Seeds of mature plants are located in the seed pod produced after flowering. The seeds can be collected from the pods and planted in a clean seed sowing mix or sand.
Let me start with the 3 P’s of Successful Gardening.
1. Planning your Garden
2. Potting Mix Preparation and
3. Planting
So, Today we will discuss on the second P of gardening, that’s Preparing the best potting Mix for your plants based on some useful scientific concepts. Please watch the video till the end. First we will discuss the Criteria for the best potting soil for your plants and then the formula or the recipe for the best all-purpose universal potting mixture for your gardening.
Well, You need to Understand this Point: Why cant I just dig up the ground and use this soil for my plants? This is because we have two major limitations of this:
1. Compaction or hardening of soil – mainly with clayey soil which can suffocate the roots.
2. Lack of Nutrients in the soil- that’s the Major NPK elements (Nitrogen, Phosphorous and Potassium) and also the minor trace elements.
Hence, the need to prepare your own potting soil arises.
Hold on friends, some more important concepts to learn before I disclose my recipe. A few criteria you should be taking care while preparing your potting mix.
1. DRAINAGE: We all know, too much water can rot your plants. So a well draining soil that quickly drains out water within a particular duration of time is important for all plants. This is the most important criteria for growing succulents and based on this you adjust the proportions of stuff like sand, perlite and other stuff.
2. WATER RETAINING CAPACITY: This is quite opposite of the first factor. So we have to add materials in such a way that the water should neither drain out too quickly nor it should stagnate in the container.
3. NUTRIENTS: This is a very important criteria in container gardening. We have to add certain nutrients into the potting mix so that your plant can produce flowering or fruiting at right time and grows in a healthy manner.
Having said that, Now Lets Start making our Potting Mix with the best and easily available ingredients.
I am showing you two formulae, One you can use purely for teres gardening which is very light weight and will not have any compaction. This can also be an ideal seed starting mix so that the seeds can push the light weight ingredients in its germination process and also to some extent sterile.
And the second one is our all purpose mix for most of our plants. You can change the proportions as per your requirement, but generally this mix will be useful for any plant. So the formula is:
1. Good quality Garden Soil about 40 percent (by good quality I mean, it should not have large stones or other large sized stuff in it).
2. Cocopeat or Peat Moss: 30 percent. If you do not have this, you can use about 10 to 20 percent River Sand. Adding more sand may result in too fast drainage which might be useful for succulents and cacti.
3. 20 to 30 percent Compost like decomposed cowdung powder or Vermicompost or leaf compost or a mix of these. These first 3 ingredients should be the minimum for your plants.
4. You can further fortify this with 5 percent of any of these or a combination of these, that is Bone Meal powder for flowering and fruiting + Neem Cake or Any oil cake Powder for anti microbial and antifungal effect for root protection.
5. Then you can also add Trichoderma or pseudomonas powder and also some beneficial fungi called Mycorrhizae. You can watch a detailed video on these useful soil fungi from a link at top right corner of this video and also in the description.
The Second Formula of Potting Mix is a light weight mix suitable for roof top gardening and also as a great seed starting mix. Here you do not use garden soil, but only
1. Cocopeat or peat moss (50 percent)
2. Compost like decomposed cowdung powder or vermicompost (30 percent)
3. Perlite or Vermiculite about 20 percent (You can check out my detailed video on the differences and benefits of Perlite and Vermiculite from a card link at top right and also from description.
4. You can optionally add the same 5 percent ingredients like bone meal, neem mix, mycorrhizae etc as discussed earlier.
