WHAT TO DO THIS MONTH

September

Moving into late summer the garden starts to take on an autumnal hue. The late flowering perennials will be performing well now, Asters, Dahlias and Japanese Anemones giving a late season treat to the eye and Apples and Plums will be ready to harvest. Enjoy the fruits of your labours and maybe think about filling any gaps or planning new borders, to take advantage of prime planting conditions again.


  • Lift and divide any herbaceous perennials which have out grown their allocated space. Leave moving Asters until spring though, they object strongly to being moved at this time of year and will often die off over winter.

  • Start thinking about protection for any tender plants you have in the garden.

  • This is one of the best months for planting, temperatures are still favourable and the ground is still warm, the soil is becoming wet and will be getting gradually wetter.

  • Spring bulbs can be bought and planted now.

  • Look out for the bare root Wallflowers in stock this month, they make a glorious contrast with Tulips in the spring and are a great, economical way of getting jewel like colours early in the season.

  • Tidy up climbing Roses for the winter taking out dead and diseased wood or crossing and rubbing branches, shorten the stems and tie in. you may well have the flowers continuing on into winter.

  • Start lifting Dahlias, Cannas and Begonias.

  • Treat your flower borders with Nemasys Vine weevil killer if you have problems with these pesky beetles. It is a biological control and needs to be applied when soil temperatures are above 5 degrees centigrade 40 degrees Fahrenheit. If you are not sure if you have them or how best to deal with them pop into the outdoor plant office or give us a call.

•If you have any trees or shrubs which you feel are in the wrong position it is a good time to move them. Dig the hole you intend to put the plant in first, this means the plant spends as little time out of the ground as possible, firm in well and keep well- watered until re-established. 

•Start thinking about ordering any bare root hedging if you have hedges to install. Beech, Hawthorn and Hazel are just some of the varieties available to plant and a pack of 10 bare root plants are a very economical way of establishing a new hedge. Stock begins coming in during November but preparation, calculating numbers and researching varieties can all be done now, then come in or give us a call and can place an order.

 

•If you are growing Pumpkins for Halloween, remove any leaves which are shading the fruit to help them ripen.
•Cut off the foliage of Maincrop Potato plants early in the month, this helps the skins to firm up and will help keep any blight spores out of the equation during harvest at the end of this month.
•Cover cabbage and other brassica crops with some fine grade netting to prevent attacks from Pidgeon’s.
•Mow the grass underneath fruit trees to make it easier to see any fallen fruit.
•Buy and sow Onion and Garlic sets.

 

•Summer bedding can still be going strong at this time of the year give it a tidy up and keep watering and feeding.

•You may now want to ring the changes and if you like to have Pansies and Violas through the winter it is worth getting them established in your containers sooner, rather than later when the weather is less kind.

•Towards the end of this month if you have any tender annuals you want to over winter like Pelargonium or Fuchsia, lift them and keep them in a pot on a windowsill or a conservatory if you do not have a heated greenhouse.

•If you have problems with Vine weevil you can drench your pots with Bayer Provado Vine weevil killer, the adults will have laid the eggs from March to September and so the grubs which cause so much damage eating plant roots will be very active by now.  This chemical can only be used in pots and must not go onto open ground. For treating flower beds I have given advice in the beds and borders section.

 

•This is a great month for renovating the lawn after the summer or establishing a new lawn by seed or by turf. Always prepare the ground well levelling and firming down as it is not so easy to correct after the grass has begun to grow up.

•Keep mowing regularly through this month.

•Apply an autumn feed high in phosphate which works to encourage good strong root growth. 

•Work on alleviating compaction by spiking the lawn can be done this month, as can raking out the Moss, improving drainage by spiking will help to stop the build-up of Moss in the lawn.

•Raking to remove the ‘thatch’ which builds up will also help to prevent the development of Moss and weeds, it allows more air into the base of the grass and improve drainage.

Always read the label and product information before use.
