Top Tips & Info
- Care Difficulty - Easy
- A few hours of morning or evening sun is mandatory, especially in the winter months.
- Be careful when watering - allowing excess moisture to sit in the cubbyholes of the stem will result in diseases like southern blight and 'heart rot'.
- Fertilise every two months using either a 'Cactus' or 'Houseplant' labelled feed.
- Repot every year or two during the spring, using a Cactus & Succulent potting mix. This is the perfect time to propagate the small offshoots that'll form at the base of the crown. Carry on reading to learn more about the top tips mentioned above.
Location & Light
A few hours of direct sunlight is a must; shady locations could lead to diseases associated with over-watering. The frequencies of irrigations solely rely on the amount of the sun received. If the Aloe begins to develop a discoloured white crown, this is typically down to too little light. Newly-propagated 'pups' must not receive any sunlight as their insufficient root systems will not soak up enough moisture to survive the harsh rays.
During the growing period, thoroughly water the soil every ten to fourteen days, allowing the soil to dry out in between. Winterising your Aloe is essential to maintain good health; keep the plant 'ticking over' by reducing the number of irrigations to every three weeks and avoid over-fertilisation. One word of advice is never to allow excess moisture to settle either in the actual crown of the plant or underneath the pot, as both will cause southern blight or even black rot. Under-watering symptoms include drooping leaves, stunted growth, and drying leaves; these can be a range of different issues, including forgetfulness, too much sunlight, or the plant being pot-bound. Over-watering symptoms include root rot, a rotting base, or sudden plant death. Aloes must have sufficient light levels (at least two hours of direct sunlight a day) to counteract the chance of root rot.
This is not a factor; however, if the Aloe is situated indoors, a quick hose down from time to time will reduce the number of dust particles covering its leaves.
Fertilise every two months during the growing period before reducing this to every three months in the autumn & winter. Although a 'Houseplant' fertiliser will still do the job, we'd recommend using a specific 'Cactus' labelled feed as it'll support the vital thirteen nutrients that this species will need to grow.
Dormancy Care & Annual Flowers
Provide a cool autumn and winter period around 15℃ (59℉) to reinforce its dormancy. Keep the roots pot-bound to add further stress onto the specimen, which in turn will significantly heighten the chance of flowering. Blooms will generally appear in the summer, during the active growth season. The following steps should be taken from early autumn until the end of winter.
Sunlight & Location
Be sure to provide a bright location with a few hours of direct sun. Although the winter rays won't necessarily hurt the plant, be careful not to fall in the trap of sun-scorch and severe dehydration. Avoid deep shade and the use of artificial lighting at night or locations that boast temperatures higher than 18℃ (64℉).
Reduce waters so that ALL of the soil becomes dry for several weeks. It's essential to keep them on the drier side to life, as they'll think that hard times are ahead and therefore will need to pass its genes on to the next generation.
During the autumn and winter, fertilisation should be performed every two months with a 'Cactus' feed. While the flowers are in development or in bloom, use a Tomato fertiliser to provide fortnightly nourishment of potassium, at monthly intervals.
This is to remind you that everything needs to be reduced - especially the watering and temperature.
This is the most significant step; reduce the temperature down by around 5℃ compared to the summertime or place in a room that's between 10º - 15℃ (50º - 59℉). You'll be at a significant disadvantage if the ambient temperature is kept constant throughout the year, as Aloes will only respond in locations that have daily fluctuations of around 7℃. Never exceed the minimum temperature as it may lead to plant death or yellowed foliage at a bare minimum. If these steps are followed successfully, you could see a show of blooms in the following summer - but remember, dealing with nature may not always provide the results you'd relish!
Common Issues with Aloe
Over-watering is the most common issue, with typical signs including a softened centre and blackened foliage. There must be periods of droughts to replicate the habitats of the east African deserts, as well as limiting the chance of diseases. Avoid waterlogging as there's no point fulfilling the phrase 'drenches between droughts' if the base of the pot is submerged.
A pale centre and deformed growth are typical signs of too little light. Offer at least an hour of direct sunlight, especially in the winter months, to provide the vital nutrients that'll be converted into plant sugars.
Scorched or browned edges are the result of too little water and over-exposure to the sun. Although Aloes are a superb choice for plants in sunny locations, those that haven't acclimatised to the harsh rays will show signs of sun-scorch and environmental shock. Prolonged exposure will significantly speed the process of dehydration, so consider transplantation into a bigger pot (in the spring) to wrap the roots around moister soil.
Over-supplementing an Aloe will bring nothing but grief in the likes of yellowing leaves and weak, dramatic growth. Although a three-month feed is an excellent way to promote good health, dry soil and fertiliser salts will quickly lead to the burning of roots. The advice for this issue is to pre-moisten the soil beforehand and reduce the frequency of fertilisations somewhat.
Aloe consists of over five hundred species, mostly originating from east and Southern Africa - for example, Madagascar, Jordan and some neighbouring islands. Aloes were first formally described in the mid 18th century by Carl Linnaeus using an old English word, alwe, that refers to the scent-similarities of an unknown east Indian tree.
10° - 25°C (50° - 78°F)
H1b (Hardiness Zone 12) - Can be grown outdoors during the summer in a sheltered location with temperatures above 12℃ (54℉), but is fine to remain indoors, too. If you decide to bring this plant outdoors, don't allow it to endure any direct sunlight as it may result in sun-scorch and dehydration. Regularly keep an eye out for pests, especially when re-introducing it back indoors.
Up to 0.7m in height and 1m in width. The ultimate height will take between 5 - 8 years to achieve.
Pruning & Maintenance
Remove yellow or dying leaves, and plant debris to encourage better-growing conditions. While pruning, always use clean utensils or shears to reduce the chance of bacterial and fungal diseases. Never cut through yellowed tissue as this may cause further damage in the likes of diseases or bacterial infections. Remember to make clean incisions as too-damaged wounds may shock the plant, causing weakened growth and a decline in health.
Via Seed or Offset Division.
Offset (Pup) Division (Easy) - For this method, it's best to divide in spring or summer and once the offshoots are at least a quarter of the mother plant's size. Remove its pot and place your hand in between the junction that connects the two; soil may have to be brushed away to get a better grip. Gently push the pup downwards while supporting the mother plant until you hear a snap. Cautiously separate the root systems, keeping great care in keeping them damage-free. Place the new plantlet in a small pot with a well-draining potting mix, much similar to the original soil, and maintain the same care routines. 'Cactus & Succulent' compost is best, or you can make your own using multipurpose compost with added grit or perlite. Provide a bright setting with temperatures around 18°C (64°F) with the majority of the soil drying out in between waters. New leaves should emerge within the six weeks, as long as the soil is kept on the drier to life.
Yellow flowers are held by a spike that'll develop each year, reaching up to 70cm in height during the spring. Each flower can last up to several days, with the blooming process lasting several weeks. Ensure to keep the plant slightly more hydrated with a fortnightly feed of Cactus Feed during this time to prolong this period.
Repot every year or two in the spring, using a 'Cactus & Succulent' labelled potting mix and the next sized pot with adequate drainage. Hydrate the plant 24hrs before tinkering with the roots to prevent the risk of transplant shock. For those situated in a darker location, introduce an extra amount of perlite and grit into the deeper portion of the pot to downplay over-watering risks.
