|Root Nodules on seedling plant started last February.|
Just today I answered an email about planting some Seabuckthorn seeds someone had purchased. Much of the information is contained in this blog, but I thought repeating the my emailed answer might be helpful. and a timely addition now.
Glad the seeds arrived in good condition. Soaking is not necessary. There have been a number of studies documenting the effects of soaking and the results are germination speed is only a day or two quicker. Not really worth the extra step, but it is an option. If chosen, I recommend a 24 hour soak.
Sow the seeds in a soil-less sterile mixture of vermiculite and peat moss. (ordinary bagged seed starting soil) at a depth of @ 1/2 cm. They should emerge in about 10 days. Normal care should be taken as you would any seedlings started indoors.
Since the number of seeds ordered are many and I don't know what facilities are at your disposal, I will expand a bit with more technical information for the professional.
These stratified Seabuckthorn seeds can be seeded indoors in pots in January or early February in vermiculite/peat moss mixture (40:60). The containers are placed in a greenhouse with a 16 hour photo-period at a temperature range between 25-27C and a 70-90% relative humidity.
Germination will occur in @10 days.
Immediately following germination and prior to the formation of true leaves, an application of fungicide may be necessary to control seedling damping-off.
Maximum growth may be obtained by using bright full-spectrum fluorescent or hi-pressure sodium lighting. A soluble starter fertilizer (10-52-10 N_P_K) should be applied with each irrigation for the first 3 weeks following planting.
After this, a complete soluble fertilizer (20-20-20, N_P_K) is applied in the same manner.
A moderate amount of air circulation is recommended. Seedlings should be acclimated (hardened off)before transplanting in the spring.
One seedling per pot should be allowed to grow for 3 months before transplantation to the field in early May. In light sandy soil the root is buried 6-8 cm deep to encourage the development of another tier of roots and the new seedlings should be watered as required.
High density planting in the field can be 1M x 1M. More commonly the rows are planted with plants 1M apart and 4M between rows.
I know that's a lot of information. For the person with a green thumb, there are some good suggestions. Not to worry though if all the details are not followed exactly. As with any young plant (or animal for that matter), infancy is a time in which care should be taken and neglect carefully avoided.
I look forward to hearing how they do. Please let me know.
All the Best - Tom
