Seedling Maintenance

The TreeProject seedlings have grown a lot since they started popping up about 6 weeks ago. They were slow in January as it wasn't very warm, but in the last week or so they have shot up.

Today I did some maintenance tasks, ensuring there is only one in each tube, and trimming roots that are emerging from the bottom of the tubes.  Some species germinated really well, but there are a couple of disappointing results.

Three quarters of the River red gums, Eucalyptus camaldulensis, have grown and are a good size:

Ninety-five percent success with the manna gums, Eucalyptus viminalis:

About 90% success with the red box, Eucalyptus polyanthemos subsp. vestita:

But poor results with a couple of others, such as the grey box, Eucalyptus microcarpa, where less than 25% of the tubes have germinated:

I was hoping for some more germination after the thunderstorms we had a couple of nights ago, and in fact a few seedlings have popped up since. Unfortunately they have mainly been in already-occupied tubes, and of species I didn't have shortages of.

  1. That must be a disappointment for you, but those other trays of seedlings look really strong and healthy.
