Green manures are a cheap and very effective way of improving the soil over the winter months in time for the spring growing season. Bio-mustard, peas, vetch and clovers are all valuable crops that can be sown directly into the ground.
What to do in April
Sow green manure crops
Divide clumps of bearded iris
Divide old clumps of bearded iris this month. Dig up them up and cut apart large clumps, planting out the smaller plants. Trim back the foliage. They'll bounce back in no time and you'll be in for a brilliant display of flowers come spring.
Sow seeds for spring flowers
Don't wait until spring to sow seeds of poppies...do it now! Prepare the ground by removing weeds and rake it over to a fine tilth. Mix the tiny seeds with sand to make them go further and scatter over the area. Cover with a fine layer of soil and water in well.
