Hi Hugo,
Thank you for the great post, a lot of information and decisionmaking digest with all these reflective questions. I am glad I have plenty of time left to think about it.
As I recall correctly, a moringa tree does not fix nitrogen; I am quite confused because there are 2 parties saying exactly the opposite when i search for it.
I live in the Netherlands, with veganic I mean vegan and organic, In other words no cultivation of vermicompost, raising chickens etc.
Peat is very fertile, but the water drainage is very poor. I could also dig for a drainage pipe into the ditch (dutch = sloot), However, I still believe that building up soil full with organic matter will be the best over any condition. Will sand not ruin the fertility in the long run? Let's say 3-5 years when I will have build the soil up.
The phacelia i use because it has a nice tap root, I thought it would be nice to sow as well, because it doesn't compete with the clover meaning more coverage, The whole principal of chop and drop is to recycle nutrients from your current ground and create higher quality soil out of it (in the long run), but it does take a couple of years to my observations.
I already am growing 2 rows of daikon radish, as soon as that's done I will amend the soil with some compost, which hopefully mixes in well with the peat. Unfortunately I have a very slow growing variety, so I will probably be too late to get another row going in summer.
What exactly do you mean by sun trap? Creating a beneficial microclimate for the vegetables?
A goumi looks very interesting, I will keep that one in consideration.
The bronze fennel also has a very interesting symbiotic mechanic, I really love that, though I am not really fond of fennel myself.
The two small patches in front of the garden are actually my green manure experiments, I will probaby chop them once it reaches decent size and use it as compost or mulch for my summer vegetables.
The Alder looks very interesting, and appealing, on the other hand I would really like to grow moringa trees, not only because it's a great challenge, but also very exclusively grown in the Netherlands.
Will several goumi be a good substitute to replace an alder?
As of now I have had no difficulties with slugs, however my neighbours find them now and then. Flea beetles I did prevent by spraying garlic infused water with a little bit of biodegradable dishwashing soap which did wonders to my arugula, eventually I want to use companion planting as well as a few beds with a netted tunnel.
