Watering: Succulents don't need much water, but don't let them dry out completely

Succulents are known for their ability to store water in their dense, shapely leaves, making them relatively drought-tolerant and self-sufficient. However, this doesn't mean they don't need watering—it just means you don't have to water them as frequently as other plants.

The amount of water your succulent needs will depend on a variety of factors, including the time of year, the depth and type of soil, sun exposure, and the ambient temperature. As a general rule of thumb, water your succulents monthly in winter, twice a month in autumn and spring, and once a week in summer. However, you may need to adjust this schedule depending on the specific needs of your plant.

It's important to pay attention to the signals your succulent is giving you. If the soil is still wet, don't water your plant. Succulents can recover from under-watering, but over-watering can be fatal. Look out for signs of thirst, such as shrivelled or dry leaves, and water your plant when you notice these. If your succulent is outdoors and exposed to the elements, it may need watering more frequently than an indoor plant.

The size of your plant will also affect how much water it needs—larger plants will require more water than smaller plants. Additionally, the type of container you use will impact your watering routine. If your container has a drainage hole, you can give your succulent more water, as excess water will drain out. If your container doesn't have a hole, be careful not to fill it with water up to the roots, as this can cause root rot.

Light: Place in full sun for 4-6 hours daily, avoiding summer afternoon heat

Succulents are sun-loving plants, but they can be sensitive to the intensity of the light. Generally, succulents require full sun for 4-6 hours daily, but this can vary depending on the season and the specific needs of your plant. During the summer, avoid exposing your succulents to direct heat in the afternoon, as this can scorch their leaves. Instead, opt for morning sun and provide shade during the hottest part of the day.

In terms of placement, consider the sun's path throughout the day when choosing a spot for your succulents. If you live in a cooler climate, positioning your succulents near a north-facing wall can help maximise their exposure to the winter sun. Alternatively, placing them under eaves can shield them from frost.

If your succulents are stretching out or losing their vibrant colour, it's a sign they're not getting enough light. Move them to a brighter location, preferably one that receives direct sunlight. Succulents can also benefit from the increased daylight hours during the warmer months, which can trigger the flowering process. However, be mindful that artificial light at night during winter may interfere with this process.

While succulents thrive in full sun, some varieties may require partial shade, especially during the hottest parts of the day in summer. Succulents are known for their adaptability and can survive in various lighting conditions, but it's important to monitor their growth and adjust their placement accordingly.

Overall, succulents in Australia will typically need plenty of sunlight to thrive. By providing them with the right amount of light and protecting them from excessive heat, you can ensure their health and beauty.

Soil and drainage: Use free-draining soil and ensure good drainage to prevent root rot

Succulents are known for their ability to tolerate drought, but this also makes them prone to rot if left in wet soil. To prevent root rot, it is crucial to use free-draining soil and ensure good drainage.

When selecting soil for your succulents, it is important to remember that drainage is key. Wild succulents tend to grow in sandy, gravelly soil, often in small, rocky crevices or cliffsides. Their native soil gets saturated during heavy rains but dries out rapidly. To mimic this environment, choose a sandy loam that is 50% to 80% coarse sand or fine gravel. If you are planting succulents in pots, select coarse grit minerals about 1/8" to 1/4" in diameter to ensure rapid drainage.

The soil's ability to drain effectively is influenced by various factors, including the quantity of water added, sunlight, airflow, and soil structure. For indoor succulents, consider using a grittier soil to prevent pests. Conversely, if you live in a hot, windy climate, you may need to use less porous soil to avoid frequent watering.

To create your own well-draining soil, mix organic and mineral components. Organic materials, such as pine bark, coconut coir, compost, or potting soil, provide nutrients and store water. Mineral constituents, including coarse sand, perlite, volcanic rock, fine gravel, and chicken grit, improve drainage. The ideal ratio of organic to mineral material is crucial to supporting growth and preventing rot, allowing you to water your succulents deeply but infrequently.

Additionally, ensure that your pots have drainage holes to facilitate water flow and prevent waterlogging, which can lead to root rot. Avoid using a layer of rocks at the bottom of the pots, as it creates pockets where water collects and breeds bacteria.

Temperature: Succulents prefer average to warm temperatures and dry air

Succulents are resilient plants that can tolerate a range of temperatures, but they do have preferences and limits. Overall, succulents prefer average to warm temperatures, typically ranging from 15°C to 26°C (60°F to 80°F). Some sources suggest that succulents can withstand temperatures as low as 4°C (40°F) or as high as 32°C (90°F). These temperature extremes can even be beneficial, acting as a "stressor" that enhances the plant's colour. For example, when exposed to colder temperatures, green succulents may turn pink or red, and purple succulents may become a darker shade of purple.

However, it's important to note that succulents are susceptible to both heat and cold damage. In the summer, high temperatures combined with full sun exposure can cause sunburn, damaging the leaves and root systems. To prevent this, relocate your succulents to a shaded area or cover them with a shade cloth during the hottest hours of the day. If you live in an area with extremely hot weather, consider planting your succulents directly into the ground instead of containers, as soil maintains a more consistent temperature despite fluctuations in the weather.

During the winter, protect your succulents from frost damage by keeping them above freezing point. Bring them indoors or cover them with a cloth or "frost blanket" to insulate them from the cold. While some succulents, known as hardy succulents, can withstand freezing temperatures, most succulents are soft succulents that are vulnerable to freezing temperatures. Their fleshy leaves, which store water, will freeze and rot if exposed to prolonged cold.

To summarise, succulents thrive in average to warm temperatures and prefer dry air. While they can tolerate some temperature fluctuations, it's important to protect them from extreme heat and cold to prevent damage and ensure their health and longevity.

Pests and leaf maintenance: Treat pests with Neem Oil. Remove dead leaves and propagate healthy fallen leaves

Succulents are resilient plants that can thrive with little maintenance. However, they are still susceptible to pests and require leaf maintenance to stay healthy. Here are some detailed tips for pest control and leaf care:

Treating Pests with Neem Oil

Neem oil is a natural pesticide made from neem seeds. While it is effective against pests on some plants, it is controversial when it comes to succulents. Some people report that using neem oil on their succulents had devastating results, as it can clog the plants' pores and cause them to suffocate. However, others have found success by heavily diluting the neem oil or applying it to the soil rather than directly to the plant. To avoid potential harm to your succulents, consider alternative pest control methods, such as isopropyl alcohol spray or plant soap.

Removing Dead Leaves

It is essential to distinguish between dead leaves and naturally dying outer leaves. Succulents grow new leaves from their centre and gradually lose their outer leaves as they mature. If you notice dead leaves in the centre of the rosette, your succulent may be in distress. However, if the dead leaves are on the outside, they can be left alone or gently removed.

Propagating Healthy Fallen Leaves

Propagating succulents from leaves is an easy and inexpensive way to grow new plants. The process varies depending on the genus and species of your succulent. Some common methods include gently twisting the leaf off the stem, ensuring a clean pull, or using sharp scissors or pruning shears to cut above a leaf on the stem. After taking the cutting or leaf, let it dry for one to three days before placing it on damp soil to encourage root growth. Depending on various factors, you can expect to see results within two to three weeks.

Frequently asked questions

Succulents are known for being low-maintenance and can survive long periods without water. However, they do need watering from time to time. As a rule of thumb, water them monthly during winter, twice a month during autumn and spring, and once a week in summer. If your succulent is in a saucer, remove any excess water to prevent soggy roots.

Succulents need lots of sunlight. Place them in full sun for 4-6 hours each day, but avoid afternoon sun in summer, which can burn the leaves. If your succulent stretches out, this is a sign that it needs more light.

Succulents prefer dry soil and good drainage. Use free-draining soil and add gravel or sand to the potting mix to improve drainage.
