My older children and I were gardening and my little kids kept trying to ineffectively participate. So, we made the little ones their own veggie and flower garden sensory tub. The little kids were so happy playing with it!
We filled the tub with some garden soil and added this beach set, which included the bucket, the watering can, the shovel and the rake. We added a few small pots. We also added some carrots, which the children could fill the dirt and plant. We also added pebbles, insects, and flowers to plant in the pots.
