How to harvest Rocket
Leaves can be harvested throughout the year about four weeks after sowing.
Pick leaves regularly, either treating plants as a ‘cut-and-come-again’ crop or pick a few leaves from multiple plants. If you pick lots of leaves from only one or two plants, it will weaken those plants growth.
Rocket flowers are edible and can be picked and used as garnish.
Allow one or two plants to go to seed. These can be either allowed to self seed, collected once ripe for either immediate use or stored in paper envelopes for the next year.
How to propagate Rocket

When large enough to handle, seedlings will need to be thinned out to 15cm (6") apart. Add these thinning's to salads.
