Gardener's Question Time

….today is like Spring here in Liverpool, so @Joey66 how do bulbs like daffs, tulips etc know the difference between Spring and Autumn?
I have a tender Hebe that is now flowering again - the hot dry summer - which harmed some plants into think they may die will encourage them to reflower - bulbs should be planted later Daffodils etc if the winter is mild - they will flower very early the dwarf Daffodils are the best bet - they tend to avoid the wind - Tete a tete is a good variety to plant in tubs or the garden if plant in a clump space then 2 inches apart ....
 

Joey will know the scientific reason but my guess would be that spring comes after a period of dormancy (winter) whereas Autumn doe not.
The leaves changing colour is due to the lack of sunshine & the breakdown of Photosynthesis in ant deciduous shrub or tree the chlorophyll declines slowly giving you the lovely autumn colour of the leaves on some trees etc - a mild Autumn will slow this process down - but eventually the leaves will fall & the tree etc will go into dormancy over winter & sprout in spring - sometimes people gather the leaves for leaf mould if stack correctly this can make a good mulch - beware though the dreaded root pest the vine weevil can live in the leaf pile ... & can cause death to plants by the young weevils eating roots till the top of the plant completely falls over .... plus they are Hermaphrodite & can reproduce themselves ..... witnessed it under glass wiped crops out using leaf mould in potting compost ...

Gardeners World Monty Don never mentions that point .....
