Greenhouse duties

I can't remember the colour codes, but each citrus has a little coloured wool tied around its stem to indicate the type and variety.
When the buds have taken, the upper part of the stem is cut off to enable the bud to grow into the new variety seedling, which is done about three weeks after budding.
Most of these will be ready to plant out in early January, about 5000 in all. Some are already gone or outside the greenhouses.
I noticed some passion fruit in the pics today as well.
