Plant for strong root growth after 14th September

Plant for strong root growth after 14th September

Here in New Zealand, it’s good to sow seeds for strong root growth next week [which is after the full moon on Monday 14th September 2019].

  • Especially good on Wednesday 18th and Thursday 19th September 2019 .


The ground is warming up, we’ve had good rains here in Auckland, and this is a great time to sow some root crops!

I might sow some more

  • daikon radish – larger seeds can be sown deeper so will stay more moist. The white root is great to eat. Some people use the top green leaves too.20160927_172201
  • beetroot – ‘seed’ is a largish cluster of seeds so can also be planted deeper.  ‘Bulls blood’ or ‘Detroit red’ are some tried and true heritage varieties we use. We also like ‘chiogga’ with it’s alternating circles of red and white – stunning looking sometimes!

  • carrots

It’s a delight when we do grow carrots. The tiny seeds need to be planted close to the surface and kept moist.  Hot sun dries them out quickly – and they die fast. Maybe it’s still early enough in Spring that the ground is moist and the sun just warm rather than hot?


It’s best to sow carrot seeds directly in the ground as they dislike root disturbance being transplanted [they are very likely to bolt straight to seed and make no root for us to eat].

Why do carrots so often make odd-shaped roots?  When the ground is

  • hard,
  • clay,
  • rocky,
  • too rich with compost/manures/fertilizer.

The delicate seedlings are programmed to send roots downwards. As they grow down, when tiny roots contact hard spots [like rocks], they go round and grow more options [= forked roots]. They also avoid anything too rich in nutrients for the rootlets to process.


PS Seeds like ‘real’ water – preferably rain. Otherwise the nearest is tank water of stored rain. Then maybe bore water, last treated water from a mains supply.

One older gardener we knew would place all sorts of containers outside to catch the rain to water her seedlings. She used all sorts from teapots on – she also grew great veg!

May you and your garden flourish


For more ideas about what to sow and when in NZ, have a look at



For more about planting by the  moon phases,

If you like experiments about when to plant for best results, a great one is to plant the same seeds in rows right beside each other [so all other conditions are identical], and label the rows with the date of planting. Then sow seeds from 1 packet at weekly intervals, each week in a new row.

This way you can see how the recommendations for best/worst seed sowing outcomes from moon-planting guides work for you. Maybe they do, and maybe they don’t.

I enjoy experimenting with such ideas – and if only I can rescue the rows from the snails and black-birds, I might even get some results to share!

Here’s a post I wrote about planting by the moon phases if you like more information and reflections on it.

Moon planting guides remind me to plant SOMETHING, plan a little, and help me have a continuous supply!
