Sowing tips

Stocked orders are shipped within 4 days.

Bananas in general

(Musa, Ensete and Musella) soak the seeds in lukewarm water for 48 hours (a thermos flask is ideal to keep the water at the right temperature), change the water every 12 hours (using Kirstenbosch seedprimer or GA3 when soaking can promote germination and also pouring boiling water beforehand is said to help the seeds germinate). Sow the seeds so deep that just a little of the seed is visible (it is assumed that light plays a role in germination), place in a warm (25-30 C.) and very light place, keep the soil moist ! Check regularly after two weeks whether seeds are already sprouting, pot the seedlings in a good potting soil with approx. 20% perlite mixed in, carefully let them get used to the sun! The seedlings will grow quickly in a warm and light place, larger plants need a lot of nutrition and a lot of water in warm weather. Wait until the plant has formed suckers (this indicates a well-developed root system) before planting winter-hardy varieties in the open ground. If necessary, wait until the second growing season.

Strelitzia's (Reginae, Nicolai, Alba, Juncea, Caudata and Mandela's Gold) and Ravenala's (Madagascariensis and Guayanensis) remove the seed coat (the brightly colored "panicle"), do not nick the seeds as is often said, this leads to rot! Then as with bananas in general.

Heliconias (various species)

Lightly sand the seeds, soak for four days in lukewarm water, change the water every 12 hours, sow on the surface of an airy soil mixture (do not completely cover the seeds, as with all banana species, light plays a role in germination), the press the mixture lightly, provide plenty of (bottom) heat and light.
Beware: Bananas sometimes take a long time to germinate, three months is no exception, it even happens that germination only takes place after 3 years, so be patient and don't throw the seed away too quickly!

Palms in general

Soak the seeds in lukewarm water for 48 hours (a thermos flask is ideal to keep the water at the right temperature), changing the water every 12 hours. Put the seeds in sealable bags filled with moist (not wet!) Perlite or Cocopeat or a mixture of both and store them warm (25-30 C.). After two weeks, check regularly whether seeds are sprouting, pot the seedlings in a good potting soil with approx. 20% perlite mixed in deep pots (palm pots of 7x7x18 cm. are ideal. Gently accustom to the sun.

Trachycarpus and Chamaerops

If the Trachycarpus seeds look very fresh, skip soaking, try to remove (peel) the "skin", the germination temperature is between 18-22 C., at higher or lower temperatures the seed will not germinate! Further as with "palms in general".

Butia capitata, B. paraguayensis and Jubaea chilensis

Have a long germination time (at least a few months) which can possibly be shortened by cracking or grinding the seed, or the like, because the (several) real seeds are located inside, but this must be done very carefully because these seeds must not be damaged , further as "palms in general".

Butia eriospatha

Keep the seeds dry in the refrigerator for a few weeks, then as with B. capitata and paraguayensis (the germination is faster than the other Butias).
All other palms: see palms in general.
If the seeds have been delivered with pulp, this must first be removed as much as possible!

Ginkgo biloba

Sow about one seed thickness deep in moist seed compost with some extra sand mixed in, lots of light!

Hedychium (various species)

Soak the seeds in hot water for 2 hours (in this case, the soaking has two functions: it softens the hard outside of the seed and removes any chemical substances that may be present that could hinder germination, in nature this happens in the gastrointestinal tract of animals that eat the seeds), then Sow on top of an airy soil mixture, make sure the seeds are not completely covered (as with banana-like seeds, for example, light appears to play a role in germination), keep warm (about 25 C.) and moist (not soaking wet), plenty of light, germination can take quite a long time (2-6 weeks).
