25. Begin Summer Seedlings
Planting seedlings for transplant is a good idea for your fall gardening projects. It would help if you planted seeds indoors because the warm, harsh summer sun will help the plant easily reach the required temperature. However, this can be not easy in the spring when you are sowing seeds the traditional way.
Perennial grasses are a great starter seed idea because they germinate and overgrow and transplant very well. You can start growing some perennials indoors in the summer to make them appear beautiful in the fall, which is also a great summer holiday educational project for kids.
