2016-17 Winter crop is growing

Русский

This winter started warmer then usual but then swung into below average with full force. Unfortunately not a lot of snow covered the ground before -15F (-26C) air moved in.

Germination of both sequoias and Doug-fir seeds has accelerated. However, there is a significant difference between seeds purchased in 2013 and in 2016. 2013 ones are germinating at a 10x rate of 2016's: approximately 50 vs 5.

Four previously germinated seedlings from 2013 batch died. The only germinated previously 2016 seedling also died.

New seeds that germinated during last 10 days were moved into the containers. I re-used the markers instead of discarding them, which will explain the reason for a mix of higher and lower numbers in the pictures that follow. I do not see much value in knowing exactly which seedlings died at this age.

The picture above shows a mix of both 2013 (300-347) and 2016 (348-352) batches.

While some seedlings already perished, some have sprouted second generation needles. Here is a close-up picture of one such seedling:

Doug-fir is germinating much faster than last year for some reason.
26 Doug-fir seeds germinated in two weeks
Norway spruce continues to grow vigorously in one large container:

I continue to water sequoias, Doug-fir and Norway spruce with Chlorothoalnil mixture for now.

  1. Can you tell me what soil mix have you ended up using and have had good results with?

    Thank you.
