Sageretia theezans


Sageretias are tender shrubs with small green leaves and leathery exfoliating bark that leaves a multicolored patchwork. In summer tiny flowers appear in the leaf axils of new shoots and produce large clusters of white followed by small blue stone fruit.

Sageretias are evergreen in milder climates but become deciduous in temperate zones when exposed to the cold of winter. Sageretia are very rarely seen for sale in Garden Centers. Chinese sweet plum has a tendency to climb and is difficult to control as an ornamental plant. There was one growing in Daffin Park, but it was removed a few years ago. Branches have spines, sharp thorn tips.





Chinese sweet plum is widely used for creating bonsai and is often sold as a bonsai for indoors. Sageretia theezans shoots from old wood and is trained using the “Clip and Grow" technique. Many bonsai Chinese sweet plum are imported from China where they are field grown. Sageretias are tender shrubs and will survive temperatures just below freezing but will drop all leaves. They must be protected from hard freezes where the roots could freeze. Sageretia are considered to be a cool house bonsai. If kept indoors, Sageretias need a position that is reasonably humid and should be cool at night as in an unheated room. Keep the soil slightly moist, never let dry completely.

In Savannah the Sageretia can be grown outdoors all year round with some protection on the few nights that dip below 25 F. Small flowers and fruit will develop if the tree is left unpruned.

Ponytail Palm- no true palm



Nolina recurvata
Beaucamea recurvata
Ponytail Palm
Bottle Palm Tree
Elephant Foot Palm
but it is not a true palm


A succulent that is often grown as a houseplant. Bottle Palm Trees need to be provided with well-drained soil and, although they will respond to being watered during summer, they should be kept dry during winter. Ponytail palms have an attractive caudex (short, thick stem).  A green rosette of strap-like leaves emerges from the head, cascading to the soil line, like a fountain spurting water from a bocksbeutel or fiasco bottle. Nolina is native to central to southeastern Mexico, in semi-desertic areas and is a curious landscape tree outdoors in freeze free locations.  As a landscape tree bottle palm may get to 15 feet tall and the caudex can slowly grow to 12 feet in diameter. With age, the trunk may develop multiple heads. Older Nolina recurvata survive lower temperatures.

can induce branching

Nolina recurvata


Ponytail palm makes a handsome "indoor bonsai", does well even in rooms with air conditioning as long as it has bright light. The brighter the light the narrower the foliage. For optimum performance full sun is best.  Keep outdoors in the heat of summer to increase the growth rate.  Bottle Palm Tree tolerates heat very well and does not appreciate frequent watering.  Never allow water to sit in the bottom of a container saucer or for soil to remain soggy as Nolina recurvata stores its water in its base. The bulbous base allows it to survive interior winter heat very well. Bonsai soil generally minimizes the chances of root rot, especially compared to the peaty mixes normally used in most tropicals. Allow the soil to dry well between waterings. With any doubt on whether or not to water the plant, don't! Over-watering is the single most frequent cause of failure.

Pony tail palms rarely need to be repotted. The root run is not very extensive so they can be "underpotted" for a considerable time. Root trim and repot in late spring when the "palm" is actively growing. Trim any large, old roots then dust with a root hormone, repot using dry soil. Push the soil into the root ball with a chop stick to eliminate any large air pockets. Do not water for at least a few days. The wounds must callus before watering or else root rot may start. Do not fertilize for a few weeks.

During the growing season, fertilize Ponytail Palms with a water-soluble fertilizer suitable for container plants. Dilute the fertilizer by half for each application to avoid damaging the roots of the tree. Always water any plant thoroughly before applying fertilizer.



In early summer cut off  the "crown" to induce branching, new heads will appear in about a month.

Nolina recurvata are dioecious, that is male and female reproductive parts are on separate plants. Masses of small white flowers are produced in summer, followed by spectacular stems of pinkish, 3-winged seeds on mature female trees. When propagated from seed, the tree forms a more desirable broader base than if propagated from offsets of a parent tree. Bonsai grown from seeds are called Misho bonsai. Soak seeds in warm water for 24 hours. Sow in fresh moist potting soil. Use a mix with good drainage. The seeds grow better with a minimum temperature of 68°F. Keep the soil moderately damp.






Most Ponytail Palms sold here are imported from China.

Feather Pine- "Trees with knees"




Taxodium distichum


Bald Cypress
Feather Pine
Care

Bald Cypress is a "deciduous conifer"- it has cones and sheds its needle-like foliage in the Autumn.

Other deciduous conifers are: 



Along the Altamaha River

Bald cypress and pond cypress are in the Taxodiaceae family. Bald cypress can be easily confused with pond cypress (Taxodium distichum var. nutans). Pond cypress has smaller, scale-like leaves pressed on the twigs. A twig of pressed pond cypress leaves resembles a pine needle pointing up or out from the stem. Bald cypress leaves are linear and feather-like  and the twigs hang down looking more pendulous than pond cypress twigs and leaves. Also, pond cypress tends to occur in still-water wetlands rather than flowing-water wetlands.






Bald cypress are found in  wetland habitats









Bald cypress is a wetland species that grows along rivers, streams, and creeks as well as in swamps with slow moving water.  It is a legendary tree of the Deep South known for its "knees," moss-draped crown, and buttressed trunk. Taxodium distichum  can live up to 600 years old Taxodium distichum is native to the coastal plains along the Gulf of Mexico and the Atlantic Ocean and north up through the Mississippi River Valley. The heartwood of old growth bald cypress is very resistant to rot.  This is not true with younger second growth trees.

trees with cones



Seeds are produced annually and good seed production occurs about every 3 years.  Seeds are dispersed more frequently by flood waters.  Under swamp conditions, the best seed germination generally takes place on a sphagnum moss or a wet-muck seedbed.  On better drained soils, seed usually fails to germinate due to lack of surface water.  Soil saturated for 1 to 3 months after seed-fall is required for germination. Seedlings require light for good growth, thus control of competing vegetation is necessary.

Bald Cypress tree is an excellent choice for someone who is just getting started with bonsai. Seeds and small trees are easily collected in this area, now is the time to find trees with cones and watch for them to turn brown so that the seed can be collected just before the cones open. The best digging time for cypress is from mid-­December to late February. Bald cypress bud back easily and will produce vigorous sprouts from the stumps. Taxodium distichum are frequently planted in groups in a single container, forming a Bonsai forest. Japanese term for growing a bonsai from seed is Misho.

Looks like bamboo, is called bamboo, but isn't bamboo.




Give this Asian native a moist, but well drained soil. Baby Panda Bamboo likes a lot of water. If outdoors in the summer it can sit in a saucer of water. Needs a few hours a day of solar light. Fertilize periodically; in the spring use a fertilizer rich in nitrogen and potassium, to encourage the development of new vegetation and of flowerings. Selectively remove “culms” to keep this grass attractive and to encourage new shoots.

Protect from hard Freezing.

Time to collect Japanese Maple Seed


The seeds have matured and are starting to turn brown.  Time to gather them before they fall to the ground!

Many poke fun at the idea of starting a bonsai from a seed. “Look how old I am I don't have time", but the creation of a bonsai from a seed is very rewarding. There is no such thing as "bonsai seed". The packs of seed marked as such, are just ordinary tree seeds that can be grown into a bonsai. They are a good source of tree seeds when none are locally available.

 in the spring,  flower 
and seed begin to appear

Bonsai grown from seeds are called Misho bonsai.

Tsukamiyose A natural forest planting can be created by scattering several to several dozen seeds in a tray. The seedlings are planted very close to each other and develop into multiple trunks with each tree naturally competing for its own light and space.


Getting tree seeds to sprout:

Acer palmatum stratification
Most tropical trees will germinate as soon as they ripen, but seeds from most temperate trees need to be sown after stratification. Stratification is a period of artificial winter that trees that are not tropical need to set off the internal clock that spring triggers and makes seed sprout as temperatures rise. Depending on the seed species, they will need 21 to 90 days of cold storage to begin to sprout. This can be done in the home refrigerator.  Use zip-lock sandwich bags with damp peat moss. A fungicide can be used in the media to keep soil borne diseases from killing the seedlings. If any of the seed germinate in the refrigerator, plant them.

When the artificial winter is over, the seeds are ready to be planted.  It is suggested that they be soaked overnight in room temperature water to improve germination percentages. Seeds that float after soaking won't germinate so toss them out.

Sow the seed in a light and friable soil mixture is so that it drains well to prevent fungus and sprinkle peat moss over them. Air should move to prevent damp-off. The air movement he says simulates natural outdoor conditions. Light friable soil dries quickly and seedling with their minimal root system can be killed in a few hours from dryness, or direct sun!

Banrot is a broad spectrum root rot fungicide in a 40% wettable powder configuration. It provides contact and systemic action for control of damping-off and root and stem-rot diseases
Subdue Maxx Controls damping-off and root and stem rots caused by pythium and phytophthora. Apply only as a soil drench or soil surface spray followed by irrigation.

Bloodgood Seedlings
"I started it from seeds myself."


Alternatives:
Chamomile tea - 2 tsp of chamomile flowers to 1 cup of boiling water allow to steep overnight or at least until cooled. Strain and then use as is to moisten growing medium before planting seeds then use in a mister to spray soil. Sage or garlic teas also have been used. Soak the seeds in a solution of hydrogen peroxide and water (1 teaspoon to 1/2 cup of water) to remove any lingering bacteria on the seeds. Some lightly sprinkle a bit of cinnamon or baking soda over planting mix used as a fungicide on plants for mildew.Two capfuls of household bleach in the water used to dampen your peat moss or vermiculite could act as a fungicide.

Always make sure horticultural tools are disinfected even if they are new, and that your planting pots are disinfected....

Disinfection of Horticultural Tools and Pots





"Empty pot of soil"
Plant tree seed in the Fall and let Mother Nature take care of your stratification. Just remember to protect them from rodents (squirrels and mice) and label that “empty pot of soil”. Once I was talking with a fellow enthusiast in the nursery and he started raking his fingers through a tray filled with soil and began talking about soil mixes. I should have labeled that flat as I had seeded the tray with  Jacaranda for a Tsukamiyose the day before!



Growing 'misho' bonsai is both economical and rewarding.
