Bearing in mind that we are in Spain, in summer now with shade temps of 30° and they are in partial shade, how should the soil feel when it needs more water? Currently it has been dry on top but slightly damp when you put your finger into the soil.

It really is how often to feed them that I need know but I suppose how often they are watered will effect this so that the nutrients aren't washed through the pot??

Cheers!
