One of the main reasons for planting poppy seeds at specific times is to ensure that plants have enough time to mature and flower before the frosts come. Spring therefore is an ideal time, providing several months of growth before poppy flower seeds mature and start producing blooms for the summer months. However, you can still put seeds in during late May to early June. This will provide a few months for plants to mature and produce blooms and, weather permitting, you could enjoy flowers until the early Autumn.
If you have forgotten to plant your poppy seeds then don’t worry and get them in as soon as possible. Hot weather and warm soil will ensure that your young seedlings grow quickly. And even if your flowering season is cut a little short, sowing poppy flower seeds in May and June is better than not having any poppies at all. So, head to One Stop Poppy Shoppe, buy some seeds, and get planting!
