If so, which fruits and other plants are you growing?
What is currently producing?
How do you manage the size of your trees?
Do you make compost, or do you only use mulch to build soil fertility?
Which climate are you in?
I’m interested to know how popular fruit forests are in this community and how others are doing it.
Yes, convert that lawn! Two plants worth considering are Prunus persica ‘Kernechter vom Vorgebirge’ and Amelanchier × lamarckii. I’ve heard great things about them, but they were growing in SW Germany, so do your own research first. What do you use for a ground cover? Clover can be a valuable ally in the fight against the grass.
