Answer: When so many different types of seeds fail, I would suspect a soil problem. You may have planted into overly cold and/or overly wet soil and that would cause the seeds to rot. The soil temperature has a big effect on germination. For example, peas are planted very early, but beans need a warm soil and squash and pumpkins need a very warm soil. Peas and beans can benefit from use of an inoculant, especially in a new garden and if those plants have not been grown in that location earlier. Next, there could be a problem with slugs and/or cutworms, or perhaps a rabbit has been nibbling. Without being there to actually see what happens, it's a bit difficult to do more than make some guesses. Since you have grown seeds before I'll assume your planting technique was fine. Since transplants were okay, I would lean more towards the cold/wet soil explanation. Raised beds would help the soil drain better and warm up earlier, but this might cause you a problem during a hot dry summer if you are not there to water deeply about every fifth day. On the oher hand, raised beds do allow you to improve the soil to near perfection. I hope you have better results next year!
