Don't throw away those citrus pips!
Citrus pips germinate easily at any time, but they will produce better plants if sown in spring or early summer.
TIP Feed lemon trees in spring and summer with a citrus plant food.
Separate the seedlings when they’re big enough to handle. They should appear after about a month. Transplant them into individual small pots filled with lime-free potting mix.
Position the pots in a cool spot in bright but indirect light. As the plants grow, replant them into larger pots. Pinch-prune for a bushy shape or trim to size in late winter.
