Erythroxylum novogranatense
« on: January 26, 2020, 12:19:15 am »

I compiled some information and a few links i know the title says novogranatense but i wish anyone with information, links about any Erythroxylum to please share.

 berries" are actually drupes. 1 seed inside like a plum or a peach.

-Germination percentages of E.coca and E.novogranatense seed were found to decrease from around 95% and 89% directly after harvesting to 29% and 0%, respectively, after 24 days of storage at 4 C (39 F)

- South American coca farmers when collecting their seeds, pour them into a container of water and the seeds that float are discarded as they are non viable


https://mycotopia.net/topic/60301-coca-seed-germination-knowledge-appreciated/

- seeds are sown from December to January in small plots (almacigas) sheltered from the sun, and the young plants when at 40-60 cm in height are placed in final planting holes (aspi), or if the ground is level, in furrows (uachos) in carefully weeded soil. The plants thrive best in hot, damp and humid locations

-Seeds are to be put under approximately 1 cm of earth, at a temperature around 28C. The soil should never dry, but not be too soaky. Seeds should germinate after 2 to 6 weeks.

-For best results use a propagator with soil heating. Adjust the soil heating to 28 Celsius this is the optimum temperature to germinate cocaseeds seedling soil PH 5-6

-Coca likes humidity, but not soaky soils, and thus grow mainly on slopes. An aerated soil is to be used. Optimal pH is 5.8, but may vary from 5 to 7. The electroconductivity (EC) is perfect at 1.2, but may vary from 0.5 to 1.6.

* explains the importance of (EC) struggling with the acidic pH. Momentary lockup/lockouts causing transient, but classic, nutrient deficiency symptoms. maybe because of the method of acidification. In their native environment, the acidity is kind of a static thing, caused by the conductivity of the iron in the soil.

-light may be used 18 hours/24.
A humidificator can be used to reach an optimal air humidity of 80%.


-After 18 monthes, the plant will start flowering, and produce seeds. The flowers are both male and female but 2 different plants need to be in contact in order to fertilize each other.
random notes found online
 side not-This is why clones from one plant will not produce Viable berries**
---------

-SeedlingMix was densely rich but sandy potting soil with lots of extra perlite. This mix has little peat content its mainly compost and sand.
Don't burry these guys! They are weak sprouters!
-use Sphagnum Moss to germinate Erys.

-1 week to 24 days after germination keep them really humid until the seed coat is off then lower it down incrementally.


*Donts*
- they do not like it if the substrate is too dense and sticky. The soil should be coarse/ loose and with a lot of hummus

 -Rapid Rooting cubes. BAD idea, had to check on them daily. They couldn't push themselves out of the cube and half died.

-Used very rich potting soil typically meant for cannabis, which burned most of the plants to death. This time I'm going heavy with plain coco coir.

-I've found they don't like being overwatered, seems their roots are very sensitive

-Most Coca plants die because they were watered with tap water. This genus does not like calcium at all, so rainwater should be used primarily.

- Most importantly, no tap water, only rainwater or treated demineralised water. The calcium in tap water kills E. coca and novo. Also no fertilizer with calcium. The substrate humos with many coarse components.

this website has some great info https://drugs-forum.com/wiki/Growing_Coca

"One of the main historical difficulties faced by late 19th / early 20th century botanists as they tried to adapt coca plants outside their original habitat was that the alkaloid production would quickly become minimal. This was mainly due to differences in atmosperic pressure, which lead people to think that it was not possible to grow alkaloid producing coca plants at low altitudes. However, while this connection is verified for species growing in the very high altitudes of the Andes, pressure and altitude being closely linked to the level of alkaloid production and most E. coca growing at lower altitude being less potent than high-altitude Andean coca, the erythroxylum coca family is quite diverse, and cross breeding between low and high altitude native strains has given birth to plants capable of producing a good concentration of alkaloids at much lower altitudes and atmospheric pressure."

- A good soil mix might be:

10% silt
20% humus/loam ("used up" compost, full of humates and fulvates)
20% fresh compost
25% iron clay based soil (like from most yards or pine forests)
25% composted wood bits or sand/grit

a mix like that will be best if it is either renewed from the top or by repotting. that means every few months SWIM can repot or else he could put new organic matter on top of the soil. putting it on top works well if there are worms in the mix; or else he can whiz it in a blender and pour the solution on the soil to get it to the lower soil. repotting 1 - 3 times a year still isn't a bad idea though.

-According to SWIM, the plants were started under flourescents and sunlight and were later moved under the 1000 MH. They are now 3-4 ' under the light, with the light on 24 hours a day. SWIM does not think the constant light is the problem. The E coca are probably 5 months old, well branched and some are flowering. The E novo var novo are 9 months old, lots of branches, and have flowered off and on for at least six months. No seeds have formed.

There us ideal, then there is practical. I’ve not had too much problem with tap water. Don’t have percentages, but once you get into dozens of seedlings, they can be acclimated. IME.

Great refresher info, though! Thanks.
