Seeds To Sow In April

We have put together a list of all the seeds available at that you can start sowing this month. There are so many delicious, organic vegetables you can start growing and beautiful flowers to brighten up your garden!

Carrots are prone to carrot fly, if you know that they are a common occurrence in your area be sure to use a net over your containers or garden. Harvesting all your carrots at once can also help, as carrot fly is usually only an issue once you start harvesting.
