Hi Crystal moon,
In the absence of manure you might like to think about replacing both its functions so
find alternative mulches like grass clippings straw woodchip , but also look for some good nutrients chicken poo , nettle or comfrey tea , bear in mind that at the moment you want to encourage flowers and fruit so look for something that is rich in phosphates and other nurtrients not just nitrogen (which just makes things grow leafy). Comfrey tea is good for this.
lucky for me comfrey is a big weed on our site. if its not on yours ask around im sure someone will be able to dig you up a bit of theirs!
good luck
