The sunnier months in April present a fresh opportunity for gardeners to sow some of the fastest-germinating seedlings, bringing a productive garden closer than you might think.

We return to Josie Lewis this week for an episode all about what she’s sowing in mid-April, how to prick out and pot on seedlings, and the simple tricks they use to keep plants growing hard and healthy at this most promising time of year.

In this episode, discover:

  • How to prick out seedlings confidently, and when to do it for promoting strong growth
  • Practical ways to get more from your dahlias, such as turning pinched tips into new plants with simple cuttings
  • Why mid‑April is the ideal time to sow cosmos and zinnias, and how to avoid the common mistake of starting them too early
  • Step‑by‑step tips for taking cuttings of pelargoniums, salvias and other favourites
  • Two slightly different but complementary approaches to hardening off plants, and how to choose a method that works for your own garden
