Culture of tropical plants in temperate climates (general)
Advice of seeding
Sow in spring, when the duration of light is growing, or full year in a heated, ventilated and lighted.
Sow 1 seed per cup of 7 to 8 cm at a depth equal to its size, a good standard commercial potting soil or a mixture of: 1 / 2 peat
1 / 4 compost
1 / 4 sand, slag, gravel ...
Very fine seeds can be planted in groups, in bowl, but a transplant operation will be necessary.Label each pot with the plant name and date of sowing. The removal of seeds within a time varies, depending on the species, 8 days to 1 year for some palm trees ...
create the warm and humid climate where the plant originated and
maintain a temperature of 25 ° to 30 ° with high humidity, the seeding
is "stewed" under glass or mini-greenhouse, close of heat.
Watering should be regular more abundant, we must keep the soil moist but not soggy, beware of excess water causing rot. It is advisable to water in rain (spray) or by soaking water (sub-irrigation), it avoids moving the seeds.
To hasten germination of hard seeds (heliconia, banana):
We soaked the seeds in warm water (renewed) for 24 to 48 h (Musa, heliconia, Ravenala, Strelitzia ...)
Or we practice scarification, namely to break or grind the seed coat (Macadamia, Cassia ...)
Conservation of seeds
seeds are not planted soon will be stored in a cool place, away from
light and moisture, for example in a opaque box food, the fridge. Some seeds have a lifetime short enough, and it is best to plant them soon.
Tips for repotting or planting:
seedlings have reached a height of 10 to 15 cm, they must be repotted
or planted in the garden if the soil is sufficiently warm (15 °)
palm seedlings must be kept in pots for several years (except in
Mediterranean climate) a periodic repotting in a deep pot filled with
good fertile soil they will grow and improve. It is imperative to return before the 1st frost, with some exceptions.
and vines can also be grown in pots or in suspension, but for maximum
flowering and thus seed, it is preferable to planting in the ground,
feet in the shade and head in the sun against a fence or arbor. Those
with rapid growth and flowering can be grown as an annual (spring
planting, summer flowering, death to the 1st frost) Others have a
longer cycle, will not flower this year's planting will be protected
from the cold. (under 10 °)
Note that most of these plants do not tolerate frost, without exception.
advise you not to plant your seedlings in the ground and make the
experience to keep some pot and return to hot, if the other does not
pass the winter ...
