  1. September is the time to buy and start planting all of your spring flowering bulbs such as; snowdrops, daffodils (Narcissus), crocus, grape hyacinths (Muscari), iris and winter windflowers (Anemone blanda).
  2. Start sowing overwintering vegetables that will be ready to harvest in late winter, next spring and summer. Get sowing and planting; onion sets, spinach, winter lettuce and Chinese cabbage.
  3. If you don’t want to sow more vegetables you could instead sow green manures. In September you can still sow mustard, grazing rye grass, winter tares and winter field bean. Sowing green manures will help reduce soil erosion, conserve nutrients in the soil and when dug into the soil act as a natural improver by adding structure and nutrients. Find out more here.
  4. September is the big fruit harvesting month. By now most of your apples, pears, plums, quince, damsons and autumn raspberries should be ripe and ready to harvest. Start thinking of recipes for your fruits and enjoy eating them. You could go apple picking and become a pomologist for the day.
  5. With fruit on your mind it’s also time to start ordering new fruit trees, fruit canes and bushes ready for planting in the late autumn or winter. Great timing if you are just setting up a new garden, planning a fruit garden or starting a gardening club. You can find plants at local tree nurseries, garden centres or online.
  6. It’s Harvest time! Harvest vegetables such as; tomatoes, salad leaves, French beans, runner beans, courgettes, cucumbers, pepper, chillies, onions, spring onions, globe artichokes and any other vegetables you are growing when they are ready.
  7. If you have an overabundance of harvested fruit and vegetables then try storing them, freezing or drying them. You could also turn them into treats by pickling them, making chutneys, jams, marmalades or adding them as flavourings to oils. You could also host a Big Soup Share and turn your harvest into a yummy soup that can be shared with your friends, neighbours, school or local community. Follow these link for our recipes and resources.  
  8. Save seeds from annuals, herbaceous perennial plants and wildflowers in the garden. Doing this gives you seeds for free to sow and grow next year. You could make an origami seed packet to store your collected seeds. But try to leave some flower seeds for birds to eat over the winter.
  9. Once they have finished flowering, you can divide your herbaceous perennial plants. This is a great way to get more plants for free! Doing this allows you to divide up a large clump of plants into many smaller clumps. It will also give the plants more space to grow. Herbaceous perennials are plants that die back to the ground each year in the winter but then re-grow and flower every year.
  10. Outdoors you can sow hardy annuals and wildflowers such as; calendula (pot marigold), field scabious, field cornflower, feverfew, delphinium (larkspur)nigella (love-in-a-mist) and poppy. You could make a wildflower piñata as a fun way to spread your wildflowers.
