Redwing, it's the unique properties lavendar....any plant...takes from the soil that is denied to the next planting of lavendar. Not just about replacing nutrients I think.
replacing st least some of the soil is essential if anyone intends to replant again with lavendar.
however, Redwing, I too am a great believer in mulching but it varies from plant to plant. My aeoniums, for example, are mulched with mpc ....I know it has a few weeks' supply of fertiliser but it soon dissipates....or garden compost. Hostas have compost mixed with dried manure and fish blood and bone. Mulching to keep weeds down as well as feeding.
My replacement lavendar hedge is growing very fast and I expect it to flower well this year from planting last autumn. Not one to photograph my own garden too much but I will post a picture in the summer....(if it flowers )
