Carefuly cracking and removing the Jujube seed shells worked great for me. 100% sprouting quote and it took only 2-3 days. With this particular tool, which englush Name I dont know, its easy to open the shells Carefuly step by step..

Hi Permies.

We are located in Uruguay on a point less then a mile from beaches (in the northeastern till southern directions)
Its very windy through many times of the year. During the last winters and springs, strong winds broke some of our trees.
Winter is sunny, humid and chilly (it usually doesn't freeze)with 10 hours of sunlight.
Wikipedia describes Uruguay's climate as:
humid subtropical (Cfa according to the Köppen climate classification). It is fairly uniform nationwide, since the country is located entirely within the temperate zone. Seasonal variations are pronounced, but extremes in temperature are rare.
The summers can get quite hot.

We would like to grow veggies throughout the whole year and we would love to have some tropical fruit trees like cheremoya and mango (which would suffer outside probably too much due to the intense weathers).

As we intend to construct another little house for living there will be the opportunity to combine it with a greenhouse.

Also we would have space for a 6 -7 m long alone standing greenhouse on a site with winter sun.

In the winter we love hanging around in greenhouses, so a included space for reading books, drinking tea etc, is a delicious imagination.

What kind of greenhouse would you recommend us?

Does a heating system make any sense?

Thank you for your inspirations and advice.

Hi permies. Well maybe I was a bit qick with posting my thoghts triggered by flying over an article.

It wasnt my intention to start a new topic here.
Thats the article                                   http://permaculturenews.org/2015/11/06/dont-try-building-hugel-swales-this-is-a-very-and-i-mean-very-bad-idea/

I know pretty few about swales and hügelculture.
Of course recommendations for my sandy downhill northeast bed are very welcome.
Greetings Aaron

Just was reading that a swale containing wood will most probably collapse one day.

Yesterday I had to dig some holes and realized once more how easy it is to remove the 10 cm layer of rhizomes. ( in Switzerland I have to deal with heavy clay which is only workable 1-2 days after heavy rain plus rhizomes Mr. Bindweed).
Thekla mentioned that it might be better not to remove the weed layer as its stabilizing the ground. ( also I saw yesterday that only the first 10 cm of sand contain humus)
Its clear, that when you remove all vegetation and dont cover the sand you will be left with a sand desert.

I could get quite soon a load of pine sawdust and I am still considering how to prepair the ground where its being unloaded and spread.
As it is pretty easy to remove the weeds, I am still considering to do that bevore sheet mulching. I would like to avoid having certain weeds like dollarweed and grases covering all the mulched area when I come back next year.

What do you think about that? Will the already existing trees be OK with that?

I will also look for a source for manure, but dont now if you can easily get big amounts, as cows and horses here usualy have lots of countryside to range.

As it is so easy to dig here and as I have a lot of wood, I could bury it in the sand bevore adding sheet mulch.( I am considering that for the north east slope area as well as to raise the lowest area which is moist throughout most of the year)

What do you think, could swales be created on the north east slope by burying wood, and would that make sense?

( eventhough sand, and maybe because of the finer dustier upper layer, I also observe water running off on the surface).

Jujube looks very interesting to me. Online there is nothing to find in Uruguay. Well, lets see. outside the Web there is a secret world full of surprises. Maybe I can bring some from Brazil or Argentinia.

Will check out vetiver. I definitely like the essential oil.
Of course we have a lot of natives that are very adopted to the local Clima.. Im gathering hints from local people who know the local flora well.

Oh yes, good to hear about a wall being possible if combined with shrubs.
I am on the lookout for non invasive bamboos too.

Thakyou Thekla. Wow thats a lot of interesting stuff to consider, research etc. Actually we wanted to build a 2 meter high stone or earthen wall on the border towards our noisy neighbours. Good to know that this might come out unpractical. I found a seller for 2 year old moringa trees. The thing is, it wont freeze here but still can get quite cold in winter nights. For now I think I will give it a try.
The winds hete are not that moist.today its again too windy and it comes fromthe southwest. Beside windprotection, I will  have to look for very resistant food trees. A seller from a local shop just told me that apples are expensive here because they are difficult to grow due to wind.

Hi Pamela. I now this movie and was already considering covering certain areas in that way. Till now it looks like I would have to go on pine sawdust. I definitely wont leave without doing a big test patch. It still scares me a bit to put a big nourishing mulch layer onto the mat of rhizome grases and dolar weeds.
