Microwaves as an Aid to Plant Propagation

25 Aug 2017 10:03 AM | Anonymous

In this 3rd week of August we should describe how useful our microwave is in our horticultural activities.

We use commercial Seed Raising and Cutting Mix for all our cutting and seed propagation. After potting on our propagation successes we place the used mix in a rice cooker (earmarked specifically for this purpose). When filled the rice cooker is placed in the microwave on high power for 15 minutes. After cooling the recycled mix is ready to use again. Occasionally we add some fresh mix.

Before sowing wattle seeds we soften the hard seed coats using the microwave. The seeds are microwaved in half a cup of water for 3 minutes. They are left to cool for 30 minutes before sowing. The photo shows how this treatment swells the seeds. The seeds are of Acacia leptoclada (see Plant Profile) a beautiful wattle from Northern NSW.

    What a great idea instead of the more energy draining and time consuming regular oven. Thanks. I will try it.
