The teddy bears have been very eager to start sowing their flower seeds and vegetable seeds for ages! But they knew they had to clean and tidy out their greenhouse before they could begin. They had simply abandoned it last year when Winter came.
Now the days are warm and sunny again, they decided it was time to start the job.
Firstly, Charlie (who, of course, is in charge of construction and maintenance) decided that both the inside glass and the outside glass of the greenhouse needed to be really clean so that the growing plants would get as much light and warmth as they needed.
