Spring bulbs inject a shot of colour under deciduous trees and shrubs
Why not perk up a cheerless area under deciduous trees in the spring with some colourful bulbs. Once the trees come into leaf and the canopy closes over it can become too dark for plants to produce flowers so spring is the best time to have a bit of colour in a woodland garden. If you don’t have a woodland in which to plant these little gems they can be planted under deciduous shrubs, but not under conifers as the soil under these trees is usually too dry and completely depleted of nutrients.
Most of these bulbs, corms or tubers are planted as dry bulbs in autumn or ‘in the green’ in spring. Buying them as dry bulbs in autumn is usually quite a lot cheaper than buying them growing in spring, but buying them ‘in the green’ can lead to a better success rate.
Most of the bulbs require a nice humus rich, well-drained soil but some need it fairly dry so extra grit must be added to the planting hole. If the planting position is likely to become sodden then don’t plant as the bulbs will just rot. Make sure the leaves are left to go yellow before you remove them, as the bulbs need them to photosynthesise and build up next years flower.
