I am starting a gardening enterprise as soon as we get back from our snow break. I have prepared a couple of resources: A Gardening Bingo . It has 8 cards An A4 sheet showing 9 plants suitable for hanging baskets. Both resources are on the TES website (register on the TES website to download the resources free of charge.)
There is also a Gardening set of picture card on the TES site which covers gardening tools and equipment,weather,and parts of plants.
