Planting bulbs in an orchard.
I have purchased 190 various naturalising Spring bulbs for my small semi shaded orchard. dwarf daffodils, small tulips, crocus, fritillaries etc. Do I need to buy bulb fibre for them and if so how many litres would be recommended? I have read that it is not wise to use ordinary garden compost as this can be injurious to the bulbs.
