Wash your whole greenhouse down including the structure and the tables or benches.

Make the glass clean with the appropriate solution.

  • You can find various brands for the job.
  • Always use products approved for greenhouse use, otherwise you could taint the air inside the greenhouse.
  • This would not be good for the plants.

Wash down anything else with mild soap and water.

  • This goes for the any of the polycarbonate or fiberglass you may have present in the greenhouse.
  • Just be gentle with cleaning so you don't scratch anything up by rubbing too hard.

If you have used wood anywhere you may need to seal it again to make sure it stays in good condition.

  • If you see that it needs to be replaced this is a good time to do that too.
  • So look it over and see what shape it is in.

After you have finished cleaning you can replace the plants.

  • Set them back in where they belong.
  • Water and feed them if you need to.
  • Make sure to remove any dead blooms and leaves, might as well groom them while sprucing everything else.

Be sure the heat is working for the winter too. Start up the heater and make sure it is operating at peak efficiency.

  • You don't want your plants getting frozen.
  • If it needs any cleaning or maintenance in anyway do it now, do not wait.
  • The motor after sitting idle all summer may need to be oiled.
  • Check on the thermostat too to make sure that it is measuring the temp accurately.

It is always good to have backup power for your greenhouse, in the form or a solar or gas powered generator in case the power goes out.

  • The plants that you have taken such good care of deserve better than to freeze just because you did not plan for this emergency.
