If you know someone with willow, and can scrounge some stems, you could even put some in now.
You could either just stick the stems into the ground, they usually root, esp if ground is wet. Put cardboard round them to keep the weeds down, with manure on top to hold it down and feed the plants as cardboard rots.
Or take a shallow trench out to get rid of majority of weed growth, (easier with a mattock) lay the stems horizontal, peg down or use some of the removed trench material upside down to hold it down, it should root and shoot along tne stem
