How do you know if a cycad seed is viable?
Water test: Take your seeds and put them in a container of water. Let them sit for about 15 minutes. Then if the seeds sink, they are still viable; if they float, they most likely will not sprout.
How often do you water cycad seeds?
After 14days, prepare a mixture of water, RootStim and a good fungicide and submerge the bag of seeds in the mixture for 24 hours. Return the damp seeds to the warmish dry place it is kept. Repeat the mixture and submerging every 14days.
How long does a cycad take to grow?
Generally cycads are regarded to be slow-growing; however, given ideal growing conditions, this species will, in five years, develop into a worthwhile garden subject with leaves of at least a metre in length. All cycads are regarded as being long-lived, surviving for hundreds of years.

Should cycad pups be removed?
Many cycads produce 'pups' from their stems and suckers from their roots. These can be removed to grow as new plants. Simply remove a pup and place into a container filled with premium potting mix that contains a slow-release fertiliser.
How do you make cycads grow faster?
Keep this plant away from any direct heat sources and place it in a location where there is natural light. If your cycad is outside, it will need full sun and your average temperature should be 70 F. (21 C.). Fertilizing four times a year will ensure proper nutrition and growth.
How do you tell if a cycad is a male or female plant?
Cycads are dioecious, having both male and females. When the sago plants have sexually matured, the female sagos begin to flower producing a basketball-sized structure. The male sago produces a long thick structure, or the male cone.
What is the lifespan of a cycad?
Cycads are incredibly long-lived, with some individuals in the wild estimated to be around 1,000 years old. One of the oldest cycads “in captivity” is in Kew Gardens in London, and it at least 228 years old. Part of the secret of their longevity is that they grow very slowly – producing just a few leaves each year.
Why are cycads so valuable?
A new study shows that cycads, which are in decline and among the world's most threatened group of plants, provide an important service to their neighboring organisms. The study found that at least two cycad species share nitrogen and carbon through the soil, thereby creating habitable environments for other organisms.
Do cycads need a lot of water?
Watering: will vary according to the individual species. Usually once a week, and more frequently during the hot summer months.
What are cycads worth?
'” One section of the Kirstenbosch National Botanical Garden in Cape Town is given over to cycads, “a group of plants so ancient that dinosaurs once roamed among them”. According to the risk bulletin, “Cycads are greatly prized by collectors, and rare specimens can sell for tens of thousands of dollars.
What are Cycads?
Cycad plants are hardy, evergreen gymnosperms (cone-bearing plants) that grow in sand or hard rock. Cycads are dioecious plants; there are separate male and female plants. The female plant produces seeds, and the male plant produces cones filled with pollen.
Why are cycads called living fossils?
Cycads have been referred to as “living fossils” because they have existed before the dinosaurs. There are roughly 300 known species of cycads and new species of cycad are still being discovered. Although botanists are discovering new species of cycads, they are becoming extinct; the main threats to the cycads are habitat destruction and the harvesting of the plant.
What temperature should a Cycad be outside?
If your cycad is outside, it will need full sun and your average temperature should be 70 F. (21 C.).
Do cycads need potting soil?
Because cycad plants are hardy, they are relatively easy to grow. The most important requirement is good drainage. If water is stagnant, the roots will rot. Cycads do well in terra cotta pots with a cactus mix or potting soil. Don’t expect rapid growth; these plants are slow growing, and like being root-bound, so there is no need to re-pot too often.
Is Cycad a good plant for beginners?
Image by MasaoTaira. Going as far back as the dinosaurs, cycad plants are great for beginner and seasoned gardeners alike. These appealing plants will not only add interest both indoors and out, but they’re easy to care for. Let’s learn more about how to grow cycads.
Is a cycad a palm?
Cycads are often confused with palms in appearance, but they are not related , as the cycad does not produce flowers or fruit. However, the cycad is closely related to the pine tree .
How long does it take for a cyclad to germinate?
Cycads propagate easily from fresh seeds, which germinate in two to three months if kept under very warm conditions. Although pretreatment is seldom necessary, older seeds benefit from soaking to rehydrate them and prompt germination.
How to grow a sago palm in a plastic pot?
Fill 4-inch plastic pots with a mixture of half perlite and half milled peat. Sow one seed in each pot. Lay the seed on the surface of the soil so the rounded end is parallel with the soil surface. Press the sago palm seed into the surface of the soil until it is two-thirds buried but still plainly visible.
How to get rid of sago palms?
Remove the Weak Seeds. Scoop out and discard any sago palm seeds that float to the surface because they are probably not viable. Plant only the seeds that sink to the bottom of the bucket. Inspect the seeds and discard any with obvious signs of mold or damage.
How to harvest sago palm seeds?
Harvest the Cycadophyta Seeds. Gather sago palm seeds when the fruit ripens from light green to a brilliant, bright orange or red color. Put on gloves before handling the seeds or any other part of the plant because they are toxic. Gather several of the fruits from the central cone.
How to grow a cycad?
Michigan State University lists maintaining a constant level of light moisture in the growing mixture as one of the most important factors in growing a healthy cycad. Add water whenever the growing mixture feels nearly dry beneath the surface but do not allow it to become soggy since the sago palm seeds will rot.
Where do cycads grow?
Commonly called sago palms, cycads (Cycas spp.) occur naturally in tropical and subtropical climates around the world. Species such as the queen sago (Cycas circinalis) and king sago (Cycas revoluta) are widely grown in warm, frost-free areas above U.S. Department of Agriculture plant hardiness zone 9, where they thrive if planted in ...

Fill a bucket ¾ way with water and putt the seeds inside. The bucket must be big enough for some seeds to be able to float and some to sink and one must be able to distinguish between the ones that float and sink.
What happens when a female cone is broken off?
The seeds will become loose on the female cone and fall or break off easily when broken off. This means the cone is ready to be harvested.
Can you write the name of a seed on a marker?
Some seeds are big enough to write the names of the species on with a marker. If you can do that the seeds are easily identifiable especially if you have seeds from more than one species.
Why are cycad seeds so special?
Cycad seeds are special in many ways regarding their development. In many species of angiosperms, seeds develop to reach a stationnary phase and wait for an external stimulus to sprout. But with cycads it’s a bit difference as the process of growth of the embryo is continuous, from pollination to germination. This explains why most cycad seeds can’t be stored for a long time and need to be sown when they’re ready to sprout. These seeds are called recalcitrant because they cannot be stored for a long time and are sentitive to dehydration.
What is the outer shell of a cycad seed?
These reserves are enclosed in a protective hard shell called sclerotesta. This envelope is covered by a fleshy layer named sarcotesta, making it look like a berry. This layer is usually brightly colored (usually red but sometimes orange, yellow or white) , probably for animal dispersal, and of gelatinous or spongious nature. It seems that the cycads toxins are not very concentrated or absent in the fleshy part of the seeds to facilitate the dispersal by animals.
How long can you store cyanad seeds?
Check from time to time that they are not developing mold. I use this technique and have not observed a decrease in germination capabilities of seeds. I tend to avoid doing it for tropical Zamia though because I prefer sowing them immediately as their shelf life is short. You can store seeds for 6-12 months easily with this method.
Why do you need to clean seeds?
If seeds are still covered by their sarcotesta, it’s necessary to clean them in order to avoid fungus development and suppress eventual germination inhibitors. Cleaning can be done using a knife to remove the fleshy layer that is more or less difficult to scrape depending of its texture. For more important quantities of seeds of gelatinous nature ( Zamia for exemple), one can use and enzyme called pectinase. Available as a power, it mut be mixed in water and kept at the right temperature for optimal activity. The time needed for cleaning will vary according to temperature, water, seed and enzyme quantities.
How hot does it have to be to grow a cyclad?
One must keep in mind that Cycad seeds successful germination relies on two main parameters: temperature (between 27°C and 32°C) and moisture (70%-100%). Seeds can be sown directly in pots but this takes more space and potting mix may be vector of fungi.
How are cyclads dispersed?
Today, Cycad seeds are usually dispersed by rodents, birds, marsupials (like wallabies) or even oceanic currents for the species with buoyant seeds. Cycads make relatively large seeds and one hypothesis is that they were dispersed by now extinct large megafauna.
How to sow seeds in a plastic bag?
Sowing using the baggy method : This method is widely used as it allows homogeneous moisture around seeds and is space savy. Only zip plastic bags and sphagnum (or peat) are necessary. These mediums are slightly acidic and bear antifungal properties. The sowing medium must be moist but not too much and can be sterilized using a microwave for 5 minutes at max power and allowed to cool down before use. The plastic bag is then filled with medium and seeds and kept in a warm spot. If the medium seems too humid, the bag can be left open for a few days until it reaches the required amount of dryness. In the case of sphagnum, no water should be released when pressed lightly with hands.
What is the most colorful Cycas cone?
In my opinion (and the opinion of most cycad collectors), the most colorful cone in the cycad world belongs to a coastal Mozambique cycad called Encephalartos ferox. Some cones of Encephalartos ferox are actually fire engine red. It is an amazing sight to see.
What is the bottle of Stella used for?
The bottle of Stella was used to provide some scale to give you a better idea of how big cycad cones can be . The Lepidozamia peroffskyana cones above are not even close to being the largest the cones in the cycad world. However, they are the largest in my cycad collection. The smallest?
Why are cycads considered the oldest seed plant?
Because cycads are a group of cone-bearing plants that are the oldest seed plants in the world. In simple terms, this means that cycads do not produce true flowers or fruit, just one or more large seed cones. Cycads are dioecious, so cycad cones are either male or female.
What is the color of the cones of Encephalartos ferox?
Some cones of Encephalartos ferox are actually fire engine red. It is an amazing sight to see. My plant is the ‘Curly Leaf’ form and the male cones are orange. Still pretty, but nothing like the red Encephalartos ferox cones I have seen in person in other gardens.
What are the primary pollinators for cycads?
As with angiosperms, insects are the primary pollinators, beetles being the most common for cycads. Below are two female cycad cones on my Lepidozamia peroffskyana that are almost ready to open and be fertilized. The bottle of Stella was used to provide some scale to give you a better idea of how big cycad cones can be.
How long does it take for Ceratozamia latifolia to germinate?
These two female cones below of a Ceratozamia vovidesii and Ceratozamia latifolia (respectively) take almost a year to go from fertilization to being able to germinate.
What is a cyclad cone?
Cycad cones – reproduction of the world’s oldest seed plants. Cycads are what I consider to be one of the most underused plant groups in people’s landscapes. Sure, some can be spiny and expensive, but the tradeoff certainly outweighs these possible negatives. For example, how many other plants can you grow in your garden ...
How long can a cycas plant stay the same size?
With suboptimal growing conditions, a plant can stay the same size for decades. One can see 25 years old Cycas revoluta specimens, grown in pots, with a caudex barely reaching 30cm while in good conditions, the stem would be over a meter. Conversely, species such as Cycas chamaoensis can be a very fast grower under tropical conditions, ...
What makes a cycad competitive?
What makes cycads competitive is their resilience : their longevity and hability to sustain an extremely slow grown when conditions are under optimal. Cycads are competitive against other plants in these habitats but are far from being in their optimal growing conditions.
What is the first aspect to consider when planting a cycad?
In order to increase chances of recovery, the first aspect to consider is the plant’s health. It’s preferable to plant a cycad that has settled well in its pot, with a good root ball.
What is a well draining medium?
It’s hard to get good results in poorly draining growing medium. A well draining medium means that water flows very quickly though it .
What is the best way to plant a plantation?
One plantation technique that’s been proven to be succesful is the use of raised beds. After having worked the soil, a small wall of desired shape and height is made and the bed is filled with adequate substrate (mix of soil, gravel, sand etc…). The bed being raised allows good drainage and the use of rocks benefits the plant by storing heat during the day and releasing it at night.
What is the main threat of root rot?
Under a temperature climate, one of the main threat is root rot linked to low temperature, poor drainage and organic matter housing fungal pathogens. Thus it’s preferable to use a very mineral substrate (even if very good results can be obtained using organic media) Another parameter to consider is the soil humidity.
Can you pull a cycad out of a pot?
Cycad roots are brittle and it’s essential to take it into account when repoting. Every damaged root is a possible point of entry for a pathogen. It’s better to wait until the plant is well established in its pot with a nice root ball before repoting. If the plant does not come out of the pot easily, one should not pull the caudex as it may provoke mechanical damages that aren’t always visible but with disastrous consequences. It’s sometimes better to sacrifice the pot by breaking/cutting it than risking root damage.
