Olive trees on my terrace! How to care for them?

Hi all,

I just acquired several baby olive trees! Most are Lechín de Sevilla, but there's one "picudo" in the mix for pollination purposes.

I have terraces, no garden, so the trees will live in pots on the terrace. In summer there's quite a bit of sun, especially on the upper terrace.

I live in southern Spain, near Granada.

Here's what I'm thinking for care. What do y'all think?

I've been advised to get 25 liter pots for them, and I shall do so shortly.

I'll be using a lightweight substrate with organic material and perlite.

I have a decent organic liquid fertilizer that I'll use once a week or so for the first few months.

I've also been advised to water twice a week for this first summer.

Companion plantings on the terrace: lavender so far, God willing a few more pots of wildflowers for a pollinator garden.

Lovely! it sounds like you have a good plan so far. The large pots will definitely get them going well. I have a lot of fruit trees in large pots (figs, oranges, lemons, jabuticaba) and they have always done quite well. The only thing to keep in mind is that in a pot you need to be super diligent about watering your plants, although olives i think don't mind getting toooooo dried out.
