Sometimes when we are at a hardware store with a section that sells plants, soils and fertilizers, the kids would request to buy seeds. The enjoy picking the seeds and imagining what sorts of plants will grow from those seeds.
We have tried to plant various flowers, fruits and vegetables. It is a joy when our first flower started flowering. The kids really enjoy planting. Sometimes we are successful, sometimes we are not. We only had one tomato from our previous time trying to plant a tomato.
Our current planting project is planting broccoli and asparagus picked out by the kids. The kids selected the seeds themselves. We planted them into little pots. The broccoli seeds sprouted after just a day or two. Amazing! It was so fast!
We are still waiting for the asparagus seedlings to sprout. It has been more than a week now. Perhaps my girl burried them a little too far into the soil so it is taking more time. My boy merely sprinkled the broccoli seeds onto the soil whereas my girl placed her seeds inside the soil. She said that is the way it is supposed to be. That is what is called planting. You have to put the seeds inside the soil not on top of it. Well, now she knows that there is more than one way to plant a vegetable. ;)
