Goji - Lycium barbarum
Growing from seed
If you have purchased fresh lycium berries, (Only possible during the fruiting season) they will come in plastic zip lock bags to maintain their moisture and viability.
The following instructions apply if you have picked your own berries and are wanting to 'plant on'.
Try and spread the pulp of the berry around.
It's a sticky business but well worth the end result. Extracting and planting the individual seeds usually just cuts down on the viability and is needlessly time consuming.
Three parts fill a tray or pot with seed raising mix, spread the berry pulp and seed and then sprinkle seed raising mix and sand lightly over the berry to about 3mm - 5mm in depth.
If you have purchased dry seed, it will need to be soaked for at least a day before planting.
Then carry one as above.
Germination is usually around 7 days but will vary with soil temperature. We would not consider sowing seed until very late winter or early Spring if the chilly nights have ceased.
Planting dry seed is as effective as presoaking but will add another week or two to germination time.
Once they have germinated.......
The pots must not dry out so be careful, but, after they have broken the soil surface they do not like to be too wet.
Once they have achieved their second set of leaves you can tease them apart and give them an individual pot.
Keep them reasonably protected until they have reached 15 cm in height.
They will usually generate one stem only in pots so it is best to put them out as soon as the weather allows so that they can shoot multiple stems.
The more stems, the more berries.
As with most young seedlings, they require regular watering, but also need to have some air circulation within the pot as well.
If the seed raise mix that you have used, holds onto the water over the period of a day, then it is possibly too dense and is retaining too much moisture for the roots to 'breathe'.
