20160401AEarly April is pretty much the heart of the indoor seed-sowing season. Remembering that you want young, strong, healthy seedlings, not overgrown, weak ones, here are good choices for you to start indoors over the next 2 weeks.

*Note that this list was developed for gardeners from northern climates, such as Canada, the Northeastern United States and colder parts of Europe, where the date of the average last frost is in late May or early June. For readers who garden in more temperate regions, I suggest you consult a specialist in your area to know what to sow in early April.

Garden writer and blogger, author of 65 gardening books, lecturer and communicator, the Laidback Gardener, Larry Hodgson, passed away in October 2022. Known for his great generosity, his thoroughness and his sense of humor, he reached several generations of amateur and professional gardeners over his 40-year career. Thanks to his son, Mathieu Hodgson, and a team of contributors, laidbackgardener.blog will continue its mission of demystifying gardening and making it more accessible to all.
