Top Tips & Info

  • Care Difficulty - Easy
  • Provide a few hours of morning or evening sun a day.
  • Allow the majority of the soil to dry out in between waters, especially during the autumn and winter months to downplay the increased risk of root rot and over-watering.
  • Supplement using a general plant fertiliser at monthly intervals throughout the year.
  • Yellowing lower leaves are the direct result of too little light and/or over-watering. Scroll down to ‘Common Issues’ for more information on this.
  • Repot every three years using a well-draining potting mix (we'd recommend a Cactus & Succulent Compost) and the next sized pot with drainage holes.




Location & Light - 🔸🔸🔸

It's essential not to situate your Mangave in a location where you can't read a newspaper. Due to the slowed rates of photosynthesis and water-uptake, the risk of root rot will dramatically increase the further you travel into the shade. The ideal setting for this plant is somewhere that can offer a few hours of morning/evening sun, or at least with over-head lighting. A bright, warm conservatory is best, or within a few metres of a south-facing window. Never situate one in a north-facing room, especially in the autumn and winter months, as there won't be enough light during the day.


Water - 🔸

Mangaves will require drenches between droughts to become sufficiently hydrated. As mentioned above, there'll always be a risk of root or heart rot with those kept in too much moisture, so allow almost all of the soil dry to dry out in between waters. Under-watering symptoms include collapsed or greyed leaves, stunted growth and crisping brown edges; these issues are usually down to too much light/heat or forgetfulness but is somewhat uncommon among gardeners. If your specimen receives several hours of light a day, we'd recommend reducing the overall time by half to counteract the development of sun-scorch. Over-watering symptoms include spotty brown leaves with yellow perimeters, stunted growth and a rotten base. Mangaves will only thrive in bright settings, so locations that are too dark will significantly increase the chance of over-watering and yellowing lower leaves.


Humidity - 🔸🔸

This is not a necessity; however, a quick hose down from time to time will hydrate the leaves and wash away dust or potential pests.


Fertilisation - 🔸

If you're someone who forgets to supplement their plants during the year, this is the plant for you. Monthly intervals are best, using either a houseplant or cactus labelled fertiliser to keep the specimen well-nourished. Never apply a 'ready-to-pour' fertiliser into dry soil without a pre-water beforehand, as this will significantly increase the risk of root-burn, with typical signs including yellowed leaves, elongated or flawed growth and a general decline of health. If you're interested in stimulating flowers in the summer, swap the feed for a potassium-based product, for example, tomato food; scroll down to 'Flowers' for more information on this!




Mangaves are a man-made hybrid between the Agave & Manfreda back in 2005. As both parents develop thorns along their leaves' upper margins, it was wholly expected for the Mangave to adopt a similar mannerism. 




Common Issues with Mangaves

Over-watering is the biggest issue when it comes to Mangaves. Typical signs of this include brown leaves with soft spots on the underside of the leaves, basal/crown rot or a collapsed stem. Not only do you have to be mindful of root rot, but you'll also have to think about which plant parts to keep dry. The soil must have periods of droughts to imitate the habitats of African and Arabian deserts, as well as limiting the chance of root rot. Its central crown must also remain dry at all times to prevent the development of basal rot. The final over-watering heads-up is to avoid waterlogging; there's no point fulfilling the ukhouseplants' phrase, 'drenches in between droughts' if the base of the pot is submerged, as root rot will arise.

A pale central crown is a typical sign of too little light. As Mangaves originate in bright locations around Africa, replicate their habitats by offering at least two hours of direct sunlight a day. 

Curled leaves and dried brown edges are the result of too little water and over-exposure to the sun. Although they can naturally do well in sun-filled locations, those that haven't acclimatised to the harsh rays will show signs of sun-scorch and environmental shock. Gradually increase the amount of light every few days, starting from an indirect location to a few hours of morning/evening sun over a few weeks. 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.

Mould or mushrooms developing on the soil means two things - too little light and over-watering. Despite the harmlessness, it'll prove unsightly to most gardeners and is therefore removed once known. To remove, replace the top two inches of the soil for a fresh batch of cactus compost. Either increase the amount of light received (no direct sunlight for the first few weeks to prevent environmental shock) or decrease the frequency of waters slightly. If the mould is accompanied by yellowing lower leaves, you may also have a case of root rot.

Origins 

Mangaves don't naturally occur in the wild as the genus is a human-made hybrid. Its parents, the Agave and Manfreda, have been formally documented in texts or books since the eighteenth century, with both originating from the central south of North America. Subsequently, all species within Manfreda have now been moved into the genus of Agave, after extensive genetic testing.


The Distribution of Agave & Manfreda (its parent plants). 

Temperature

8° - 32°C   (46° - 90°F)
H1c  (Hardiness Zone 11)  - Can be grown outdoors between late spring and summer throughout most of the UK while nighttime temperatures are above 10℃ (50℉). If you decide to bring the plant outdoors, don't allow it to endure more than an hour of direct sunlight a day as it may result in sun-scorch. Regularly keep an eye out for pests, especially when re-introducing back indoors.


Spread

Up to 0.4m in height and 0.4m in width once they reach maturity. The ultimate height will take between 5 - 10 years to achieve, with 5cm of growth being put out per year.


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.


Propagation

Via Seeds & Basal Offsets (Pups).

Basal Offset Division (Easy) - Your plant will produce several basal offsets that can be separated once they have a sufficient root system, and surpass 4cm (1.5 inches) in width & height. If possible, water the soil 24hrs before the main event to reduce the risk of transplant shock when its dry root systems are over-fingered. Take the plant out of its pot and place your fingers close to the nodal junction - compost may have to be removed for better access. Push the chosen offset downwards until you hear a snap. Separate the foliage and its root system away from the mother plant, mentally noting the high risk of damage. Transplant in the appropriate sized pot with a fresh batch of cactus labelled soil. Maintain evenly moist soil and situate it in a bright, indirect location away from any direct sunlight for the first six weeks. After this period, treat it like a mature specimen, following the care tips above!


Flowers

The chance of a Mangave producing a flower will be highly unlikely due to the unfavoured growing conditions indoors. If the specimen does flower though, a thick tubular stalk will develop during late spring, producing a show of colour for several weeks. The one-metre (3ft) spike will produce clusters of yellow, pink, red or white flowers along the shaft, forming a tree-like structure. If pollinated successfully, the seeds can take several months to develop and can be propagated in the following spring. Its parent plant, the Agave, is mostly monocarpic, meaning that the specimen will die shortly after flowering - it is still unknown whether Managves follow this same pattern.


Repotting

Repot every two years in spring using a 'cactus' labelled potting mix and the next sized pot with adequate drainage. 'Pup' cuttings can be taken during the repotting process; scroll up to 'Propagation' for more information. 

Hydrate the plant 24hrs before the tinkering with the roots to prevent the chance 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.
