Thanks for the link to that article! I agree with your friends tip regarding NOT up-planting into too large of a container. I once overheard someone at a garden center telling another person who was buying a small 4" potted plant that they should repot it into a gallon or larger size container, saying it would have more room to grow faster!%&*@!
The kitchen utensil idea for potting is a great tip! I've used old forks for digging, they work well especially when planting terrariums. Knives come in handy for many gardening chores too! In the past I'd use old wooden spoons for digging but always ended up breaking the handles so they are only used as stakes for houseplants. For digging tools one can find very inexpensive kitchen utensils at thrift stores!
