In the garden this week: May 6, 2011

• Get green crops sown urgently in bare areas of the vegetable garden. You are running out of time for the seeds to germinate and start growing before winter slows all growth.

• Finish the autumn feeding round as a priority. There is no point in feeding plants which have stopped growing for winter but we still have a little warmth left before the full blast of winter returns to stay.

• Make the final cuts to the root balls of large plants you plan to move soon. You should have cut the first two sides some weeks ago. Cut the other two sides and beneath the plant and leave it to rest for another week or two before moving it. You can move quite substantial plants as long as you have enough combined physical strength (or mechanical equipment) to take a very large root mass with it. Prepare the new location in advance so when you come to do the move, the plant is not left with its roots exposed to drying winds or light for long.

• It is the very last chance to sow seed of quick maturing green vegetables such as mizuna and other Asian greens, spinach and winter lettuce if you are to ensure continued supply through the colder times.

• As winter looms, sowing microgreens in seed trays can be a quick and nutritious harvest, especially if you have a glasshouse, conservatory or large eaves to protect the germinating seeds and to lift the temperature. Pretty well any and every vegetable can be eaten as a microgreen which is when the first half dozen young and tender leaves appear. BBC Gardeners’ World was recommending it as a great way to use up leftover seeds remaining in open packets from last year which seemed sensible.

• The grass seed should be calling you if you still have bare areas to sow. You will get better results if you do it immediately rather than in the depths of winter.

• The very large stinky plant shown on our newspaper’s garden pages last week was in fact the Titan Arum by common name (or Amorphophallus titanum, to be more botanically correct). It has one of the largest flowers in the world and smells so revolting because it relies on tricking beetles and flies that usually feed on rotting meat in order to be pollinated.
