Biodynamic Gardening Notes 21 - 27 December

The December solstice occurs at 15:30 on the 22 December-  Happy Summer!! With the perigee of the moon on Thursday, the 22nd, the moon is at its closest to the earth.  Perigee brings greater moisture and a tendency towards fungal growth. So keep a close eye on those plants prone to blights and mildews.

Casuarina tea, seaweed brew and witch’s brew give support to the plants and help them to overcome any fungus, mildews and/or rusts which may be starting.

With the new moon on Sunday 25th at 04:06, the moon is again waxing.  Indian agriculture recognized the day before New Moon as No Moon day, a day on which no agricultural work was done.

A Moon node will occur on Friday the 23rd at 21:37.  Moon nodes occur where the moon’s path crosses the path of the Sun.  The influence of the node lasts for approximately 2 hours on either side of the node.  The effect is similar to that of an eclipse of the Sun by the Moon and it is best to avoid any agricultural or horticultural work for this brief period (Biodynamic Resource Manual, 53).

The moon is ascending this week until Saturday morning – The earth breathes out.  We see this as growth activity above the soil.  Growth forces and saps flow upwards more strongly and increase the plants vitality. This is the time to spray horn silica preparation 501, cultivate at the appropriate constellation before sowing, harvest on an air constellation plants for medicinal purposes, flowers and plants for preparation making and field crops such as silage and hay (Biodynamic Resource Manual, 51-53).

The moon begins descending on Saturday evening – The earth is breathing in and drawing growth forces back down below the soil surface.  The lower parts of the plants, especially the roots, are activated.  Activities that take advantage of the descending moon include making and spreading compost, transplanting seedlings and trees, taking and planting cuttings, and cultivating soil.

The moon is in an air sign on Wednesday and Thursday until 13:40.  Air signs are favourable for flower plants.  These include all the plants, which are grown for their flowers, and where we want a long flowering time: garden flowers, medicinal and preparation flowers, bulbs and broccoli.

On Thursday, Friday and Saturday until 15:16, the moon is in a water sign. Water signs are favourable for leaf plants.  These include all the plants whose leaves we harvest: cabbages, cauliflower, parsley, coriander, lettuce, spinach, bok choy, silver beet, asparagus and fennel.

For the rest of Saturday, Sunday and Monday until 18:19, the moon is in a fire sign.  Warmth or fire signs are favourable for fruit plants.  These include all plants whose seed fruit we harvest: beans, peas, grains, cucumbers, squashes, lentils, corn, capsicums, rice, soya, tomatoes, zucchini, eggplant, strawberries and fruit trees.

The moon then moves into an earth sign until Thursday at 00:16. Earth signs are favourable for root plants.  These included all plants whose roots we harvest: carrots, parsnips, radishes, beetroot, celeriac, swedes, potatoes, onions and garlic.
