Answer: The seed explosion is a typical problem, so you are not alone! Using a cold frame can be very helpful in managing the flow of plants to the out of doors and making room indoors. Using restraint in starting a realistic number of plants can also be helpful. (Many seeds can with care be kept successfully for use next year.) Many plants can also be direct seeded in the garden to avoid the use of precious indoor space. Here are some discussions about seed starting, including those helpful charts. Enjoy!
You will notice that most of the plants addressed above are annuals, with just a few perennials. The reason for this is that many perennials are preferably propagated by cutting or division. You will find some good informaiton about a number of perennials in the following article.
Please also note that many perennials require a chilling period prior to germination. This can be done at home by placing the seeds in a plastic bag of slightly moist soilless mix or peat moss or vermiculite and placing that in the refrigerator for the required amount of time. Thirty days is a typical time frame although this varies depending on the specific plant. You will need to check the germination requirements for each particular perennial, as some have very specific needs in terms of chilling and or soil temperature.
Good luck with your seeds!
