Become a windowsill propagator

Raising your own plants on a well-lit and warm windowsill is a great way to get a head start if you don’t have a greenhouse. In fact, that’s how I first got interested in raising my own plants from scratch. The immediate thing you discover when you try windowsill propagation for the first time, is that getting seed to germinate is the easy bit. Finding sufficient space to keep the resulting seedlings and young plants healthy and growing well is far more challenging.

How to make the most of your windowsill propagator

  • Sow cautiously
  • Choose new and unusual varieties
  • Invest in a propagator
  • Use modular trays and mini-seedtrays
  • Add shelves or buy a coldframe
  • Maintain the right temperature
  • Make a seedling reflector box


Other Tips

  • Sadly weeds are now starting to grow again, so it is best to keep on top of them now before they start to get out of hand.
  • Open greenhouse doors and ventilate on warm days.
  • Protect new spring shoots from slugs.
  • Time to plant summer flowering bulbs.
  • Clumping perennials can grow too big and so lift and divide the clumps.
  • You can once again start mowing the lawns, but only if necessary.
  • All planted containers can be top dressed with fresh compost.
  • Start feeding fish and using pond fountains again.  If you have a pond heater it can be turned off in March.
