Obelixx has covered it all I guess Lucid
the best thing to do is to plant things that your own conditions provide....viz., light sandy soil or heavy clay; free draining or waterlogged. Acid or alkaline. Warm or cold. So research and understand your plants to see what they imdividually need
every garden has its own micro climates within it. More sheltered, more shady or even different soil so planting will vary accordingly
some plants require more feeding and better soil.....so you add compost, manure etc. Others like poor soil (..i.e. With little added organic matter) .....you mentioned lavendar Lucid.......where drainage is very good and roots etc are warm.
I grow osteospermums, for exqmple. They are planted where my soil is warm and
I do not add any compost when plant them. Heleniums like plenty of manure and the like so I add this at planting time and thereafter. I create borders to accommodate plants of similar needs
however, even after all this preparation, plants will show if they are not happy so you move them. Eventually you will get it right Lucid
