I set up a table to work on and we first of all opened up the two packages inside where they could do their labels and see what was on offer. One kit was vegetables, and these were planted as suggested in a little patch directly into the garden. I worte the labels and they added stickers to them, I find the packets of compressed coir seed mix (you re-constitute into a bucket with water) are great for covering a thin layer over the planted seeds.
Then the next kit was flowers for a butterlfy garden but they had to be started in pots, so those labels were made as well, and placed on thier little potting table at the back of the garden.
They really enjoyed the pizza kit - water was added and when they determined that the little pods had absorbed as much water as they could, we labelled them with the labels supplied and planted the seeds.
