Review of spring polyculture patch

This bed was started in the spring of 2014.  Originally I just needed somewhere to transplant a number of perennial vegetables from my first bed in this garden (below) which was about to be covered over with an extension to the house.


First polyculture patch, September 2013

The original polyculture bed that I was about to lose had been ‘constructed’ the previous year  from all manner of organic materials found in the garden – decomposed leaves etc from the hedge, ivy from the hedge, lawn cuttings, hedge trimmings and more.  Over the first growing season it had taken on a reasonable texture and I wanted to re-use this material.

The spring polyculture bed lies on the southern border of the garden adjacent to an evergreen hedge.  The garden slopes down to the south and also to the west, so the corner of this bed that lies in the south west corner of the garden is damp and shady as it also lies in the shade of the neighbouring house and fence.  It is a curvy shape, about 6.5 m long and between 1.75 and 2 m deep.

On top of the lawn, without removing any turf, I first laid some decent sized branches that had died within the hedge and some that I had also cut out.  On top and amongst these I placed other woody, twiggy materials and then covered these with the material from the original polyculture.  I put an edge of stones taken from other parts of the garden and put a decorative edge of willow round it. To my mind the decorative edge was not strictly necessary, but knowing that the planting was going to be unconventional the edging was included to provide some reassurance to the neighbours.

Over time the bed has been extended lengthways to where it meets an apple tree.  It has also been built up with upturned turfs removed from elsewhere in the garden and lawn cuttings.

The current aims is for this bed are:

  • To grow leafy greens and fruits
  • For the slightly newer westerly end, which is sunnier and better drained – to grow different onions and a few root vegetables.
  • Across the whole bed to supplement the edible planting with herbs and flowers for both visual effect and for the insects
  • To be as maintenance free as possible

The table below gives a comprehensive list of what is in the bed at the moment.  As noted in my previous review posts in the table the purposes the plants can have are:

  • Edible
  • Flowering
  • Medicinal properties
  • For biomass – at the end of the season, or sooner if they are too large for their space I cut back plants and mulch the ground where they grew, feeding organic material to the soil.
  • To supply nitrogen
  • To help break up the soil

My observation is that every plant that flowered attracted a good deal of insect life and was also visually delightful so my notation of ‘flowers’ in the table is intended to reflect this dual purpose (unless noted otherwise the flowering period is summer).

Name Purpose When sown and notes
Root vegetables    
Jerusalem artichoke Edible root



Probably planted 2014

Will harvest later and replant for next year.

Not harvested, more in the garden than we need.

Flowering plants    
Bugle Flowers, not edible Transplanted from elsewhere in the garden for edging.
Buttercup (creeping) Flowers Already in the garden.  I always pull this up when I see it.
Calendula Flowers Has been re-seeding itself each year
Clove root Wild flower Already in the garden.  I always pull this up when I see it.
Daffodil Spring flowers

Pulmonaria Flowers, not edible Spring flowering plant.
Radish Flowers Has been in the bed for several years, self seeding each year.  Not grown for root but for flowers which are amazing.  Flowers are edible as are young pods and flower shoots.


Self heal Medicinal herb


Transplanted in 2014 from elsewhere in garden
Wild marjoram Culinary herb


Has been in the bed since the beginning, lovely!
Yarrow Flowers
Dock Wild plant

Tap root to break up stony soil

Leaves for accumulating nutrients

Here already

Leaves pulled when too large / encroaching on other plants and mulched on bed

Spring pea Garden plant bought for early flowers and nitrogen fixing.
Ground ivy Spread from next door and is prone to over run this and other beds.  I will be removing it as far as possible next year.


This bed very quickly established itself, looking very good and producing harvests in its first year.

It has continued to be easy to look after, productive and attractive!



Spring polypatch in August 2015 (second year)


  • Lamb’s lettuce which self seeds from year to year. Harvests can start early in the year and last for several months until the plants run to flower and seed.
  • Land cress – some plants stay in situ and new ones are self set. Harvests are from early in the year for several months.  Later, larger leaves can be cooked.
  • Wild rocket – harvests are from spring to late autumn every year.
  • Leaf beet – some plants stay in situ and new ones are self set. Harvests are from spring until the plants send up flower shoots.  I let the seeds ripen and collect them to share with others.
  • Variegated Daubenton’s kale does not flower and is potentially ‘harvestable’ all year round. This year has been a very good year with harvests through much of the summer.  I take cuttings in autumn and winter to propagate more plants.
  • Other kales – currently Taunton Deane and Asturian kale. Harvestable in the spring, autumn and winter.
  • Herby harvests have included chives and lemon balm. The former for salads and the latter for herbal tea to help me sleep – for which it is very effective.

Asturian kale, spring polypatch August 2016



This bed is elevated above the level of the underlying stony, clay soil and has a high proportion of organic material within it.  It has developed a lovely textured soil, full of worms that seems very fertile and produces good, healthy plants. It doesn’t need any additional edging to hold it in place.

I have tried growing peas in this bed for additional nitrogen fixing, but they don’t grow at all well.  I will try with more field beans next year, which I think I have used here before.

Flowers and biodiversity

This bed has lots of flowers in the spring – wild garlic, three cornered leek, sweet cicely, forget me nots, pulmonaria, honesty and more.  In the summer it is awash with radish and marjoram flowers but could include more variety, which is something to think about for next year.

Because of the dampness here I have several times spotted frogs and toads lurking just beneath the soil surface.  There are no ponds or streams very close so it is good that this provides a suitably damp habitat for them.


This bed looks after itself very well apart from the need to keep on top of the buttercups that would surely over run it in this damp corner if I did not remove them.  They still grow in the lawn behind the bed, so will continue to be a ‘problem’.

There is not a problem with slugs here, though you might expect that given the damp conditions.  This is due at least in part to them not really being present when I started this garden.

Cabbage white butterflies are a problem later in the year.  To begin with I do take off either the eggs or the affected leaves, but after a while they get ahead of me and I give up.  This year when we went on holiday in September there were lots of caterpillars all over the kales, but by the end of October the plants had re-grown and I was harvesting

About Anni Kelsey

I love forest gardens and forest gardening, nature, reading and everything good about being alive. I have written two books - the garden of equal delights (2020) - about the principles and practice of forest gardening; and Edible Perennial Gardening (2014) - about growing perennial vegetables in polycultures, which is basically forest gardening concentrating on the lower layers.

    I absolutely loved the wattle fence you started with. Then I saw the stone. Really, really, nice. The garden looks very full. I can’t wait to hear how the soil improves over time with such diverse biomass. Thanks for posting in such detail

      Thank you, yes I think it did look nice, but it has now mostly rotted with the soil being quite damp. There are stones round most of the edge and at the back some plants instead. Iwill try to remember to do a specific post about the soil reasonably soon.
