Robinia Coppice, Gravity Fed Drip Irrigation, Bee Garden and Forest Garden Plants - Week 21 - The Polyculture Project

It's been another hot and dry week here in Shipka which is quite typical for this time of year. It's very common for us to receive no significant rain during August, September and sometimes through to October. In stark contrast to Spring and early summer, where you can feel the vitality as you move around the landscape, this time of year the heat and drought-induced stress and strain is mostly what emanates. Thankfully we have plenty of mulch on the soils and a reliable source of irrigation so the gardens are holding up quite well.

Here's what we've been up to this week           

But first just to let you know we've revamped our Online Store where you can find Forest Garden/ Permaculture Plants, Seeds, Cuttings, Bulbs, Rhizomes and Polyculture Multi-packs along with digital goods and services such as Online Courses, Webinars, eBooks, and Online Consultancy and finally we've added a Bulk Fruit and Nut Tree order form for Farms, Orchards, Nurseries, and Large Regenerative Landscape Projects. If there is anything in the store you would like to see but is not there, please let us know. We hope you enjoy the store and find something you like :) It's your purchases that keep our Project going. Thank you. Enter Our Store Here

Robinia Coppice - Eleutheria 

Three seasons ago we cut down a number of Robinia pseudoacacia - Black Locust  trees in a small plot we have on the border of a local woodland. The last few years we have returned to the area to thin the stools and remove the weeds growing around the regrowth. Last week we returned and it seems the coppice is coming on well. We'll be back in woodland next week to remove a few more mature Robinia pseudoacacia - Black Locust  trees for firewood and let more light into the coppice stools. Here's Jolanda and Ryan working in the woodland.  

Nearby the Robinia pseudoacacia - Black Locust coppice we have a small plot of land that we are intending to plant a bee garden composed of trees that provide excellent pollinator support and patches of native herbs that flower throughout the year. There is a fair bit of scrub spreading from the boundary hedging into the planting zone, so we starting cutting the encroaching shrubs and young trees in order to make way for the new plantings. We'd like to retain a 3 m wide buffer of the scrub as it's great habitat, and the intention is to plant boundary trees Castanea sativa - Sweet Chestnut and Corylus avellana - Hazelnut  among the scrub. The scrub is great for planting trees into as it provides protection from herbivores such as wild deer and domestic goats and sheep. 

Here is the design and description for the Bee Garden - Eudaimonia. You can find the location of this garden and the Robinia coppice- Eleutheria in the map at the bottom of this page  

For more information on trees for bees check out our previous post here. We also have a trees for bees multi-pack available from our store that you can order here

The selection of trees and shrubs provide an excellent source of bee fodder from as early as February right through to September. Click on the plant names for more information. 

Gravity Fed Drip Irrigation - Ataraxia 

Simon has been experimenting with gravity fed irrigation for the perennial polyculture trial beds where we have planted Cornus mas - Cornellian Cherry and Elaeagnus umbellata - Autumn Olive 

An illustration of the planting pattern in the above bed 

Using a manual diaphragm hand pump attached to a inlet hose in the pond with the outlet lower than the inlet we pump the water from the pond. The hand pump can move 2724 L of water per hour but with the outlet located lower than the inlet, gravity will do the job for you and you can leave the water to flow.

We made small 0.3 - 0.5 cm diameter holes at each plant location (every 2 m) along the hose at 10 locations and each location the water flowed well via gravity. Simon recorded the time it took to fill 1 L at each location and this varied from 1 mins 30 seconds - 2 minutes. There were some problems with algae clogging the holes, however we did not have the filter attached to the inlet so I don't expect this will be a problem once we have fitted the filter.  Here you can see the water flow at the hole in the hose at the location of a Elaeagnus umbellata - Autumn Olive  

It seems to be a really simple,lost cost and effective way to water these beds. You can find the hand pumps on ebay for under €20 and the hosing can be used for multiple beds as long as the plant spacing is the same as it is for our perennial polyculture beds. Based on our initial observations it should take 1 hr to apply 20 L of water to each plant in the 24 m long bed via this gravity fed drip irrigation system. I need to take a few elevations measurements to find the optimal application of this as for the same size beds placed a little higher in the landscape the drip irrigation does not work.   

Weeding Raised Beds - Phronesis 

 Preparing sheet mulched beds a year before planting works really well with all of the organic matter decomposing thoroughly before the plants arrives. We've found the sheet mulched beds do need to be weeded 2 or 3 times during that first year with the best times being when the weeds are about to set seed. This is the second time we have weeded the beds this year and on this occasion the main weeds growing in the beds are Convolvulus arvensis - Field Bindweed. Here's the crew weeding the beds.

Paul found this beautiful caterpillar in the beds while weeding. Not sure what it is.

Open Day 

Thanks everyone for coming to the open day last Saturday. Here's the group at the 1 year old forest garden in Ataraxia. Thanks Simon for the photo. Our next open day will be spring 2020.  

Allium tuberosum  - Garlic Chives are in full flower. These are one of my favourite perennial vegetables. The bodacious flowers, very attractive to bees, are on show from August - September. Being from the Allium family it is said to be a good companion plant in the garden confusing many pests with their strong aroma. The plant has many medicinal properties including the leaves and bulbs used on bites, cuts and wounds. We have the plants planted along the border of our Asparagus officinalis - Asparagus patch that you can see growing in the background in the below photos. 

We've been free ranging the ducks with their ducklings in our garden which is probably not a great idea as the 9 ducklings are now 5. I'm not sure what is happening to them but I did find one duckling had caught it's head between some rocks in the pond and had drowned. Perhaps the cats are picking them off as well.
