October is here, and if the weather allows this can be one of the most colourful months in the garden. Late flowering bulbs and herbaceous perennials are complimented by the wonderful changing foliage colours of many deciduous trees and shrubs. The fruits and berries of many plants are also a big feature this month. So fingers crossed for a relatively calm month, although strong October gales can often lead to an all too short season of autumn colour.

In this month’s edition of the podcast we look at seasonal gardening jobs to do in the garden during the month of October and our plant of the month for October, Liquidambar styraciflua 'Worplesdon'.

Plant of the Month

Our plant of the month for October is Liquidambar styraciflua 'Worplesdon'.

  • Flowers: Small inconspicuous bright green flowers in May; clusters of spikey fruits in autumn
  • Foliage: five-lobed, maple-like bright green leaves turning yellowish, orange then purple in autumn. Best colours are produced in acidic soil, so you could add sulphur to lower the soil's pH.
  • Soil: moist, well drained, acidic to neutral soil, drought resistant
  • RHS Award of Garden Merit
  • Generally pest and disease free; low maintenance
  • Maintenance: minimal pruning required, prune dead, diseased and crossing branches in late autumn or winter. Apply manure or well-rotted garden compost when planting and stake firmly.

Jobs in the Garden

  • Plant a Hedge
    • Many hedging plants are available to purchase as bare root plants during the autumn months. This makes planting a new hedge at this time of year cheaper than at other times of the year when only container grown plants are available.
    • Prepare the site carefully for a new hedge, dig in plenty of well-rotted manure or compost into the planting trench.
    • Take note of recommended distances between plants; the closer the plants are together the quicker the hedge will fill out. If you want a thick hedge, consider staggering the planting in a zig-zag formation effectively making the hedge two plants wide.
    • If you are happy to, use native hedging plants in your garden to encourage wildlife in to your garden.
    • Water the hedge well, especially during the first year of establishment.
  • Autumn Lawn Treatment
    • The autumn is a good time to scarify a lawn, removing thatch and moss from the grass.
    • Scarification allows the healthy grass shoots to thrive and encourages good air ventilation around the root zone.
    • Autumn lawn treatment can also be applied this month. Specially formulated, autumn lawn treatments are different to those used during the spring and summer because the priority is on strong root growth and development instead of the lush foliage growth aim of the spring and summer treatments.
  • Continue Spring Bulb Planting
    • Spring flowering bulbs should be planted in the autumn whilst the soil is still frost free and workable.
    • Some bulbs can cope better with wet winter soil than others. So refer to the planting instructions and if free draining soil is required add grit into the planting hole and around the crowns of the bulbs.
  • Spread a net over garden ponds to catch falling leaves
  • Lift and divide congested herbaceous perennials, keep the vigorous outer shoots
  • Lift and store tender bulbs e.g. Gladioli
  • Plant bare rooted plants e.g. roses, raspberries
  • Start to move tender pot grown plants into frost free greenhouses or conservatories
  • Plant up hanging baskets and tubs with hardy autumn and winter bedding
  • Start to clear up autumn leaf fall
  • Lightly fork over borders so that they absorb autumn rainfall quickly and efficiently
  • Dead-heading
  • Regular lawn mowing (raise the height of cut in very dry weather)
  • Trim border edges
