Hola Andy and Karen
From one SEO to another nice to meet someone in the business, you might come in handy!

Gina was right, don´t worry too much about the silly questions that is what the forum is for you are not expected to be an expert

From the sounds of things you just need to cultivate your soil, when I moved to Monda we were lucky as we converted a stable but prior to that it was full of horse poo! yummy

We put all this horse poo on the section of our garden that we chose to grow from, over the past 18 months more compost has been added to the mix, hand weeding (which is good for turning the soil and adding extra nutrients) - I do not use RoundUp or chemicals on my soil where I grow, all weeds are picked by hand (yawn LOL).
We have a section here while details what plants grow in what soils, we have very clay soil here in Monda, as does Gina in Coín, so top soil needs to be prepared or plant thrown in that enjoy clay.
We now successfully grow
Tomatoes
Olives (who doesn´t lol)
Oranges
Grapefruits
Lemons (still trying to keep the tree alive!)
Raspberries
Strawberries
Kiwis
Onions
Garlic
Nectarines
Passionfruits
Melons
Blackberries
I failed last year with cauliflowers and carrots but that is because carrots like crap soil so if you have a lot of that get going with carrots! They like sandy, rocky earth, good soil makes them grow funny, some of mine last year looked very deformed because I placed them in the lovely rich earth
Anyway I will stop going on
