September 2020

 

There is still so much uncertainty in our daily lives, but mother nature is preparing for her wonderfully predictable autumn fanfare of glorious colour … at least this we can be sure of!

The autumn months are some of the busiest in the gardening calendar, and with so many more of you having caught the gardening bug, I hope this newsletter and garden tasks will help you get on top of all there is to be done.

With the wonderful extended balmy weather still with us, it’s easy to understand why autumn is the ideal time to plant. The ground is warm, enabling roots to establish easily, whilst the top growth is slowing down. Generally speaking, plants planted in autumn are stronger, bigger and more robust the following summer than those planted in spring. So, if you noticed gaps in your garden or ‘lulls’ when there wasn’t anything grabbing your attention earlier in the season, plant something now to rectify the situation next year.

If it’s autumn ‘stars’ you’re after, we have some wonderful Acers, grasses, sedums and other late summer performers. Each week brings in new plant stock, so there is always something lovely to choose from. Currently we have some beautiful Heuchera, Gaura and Japanese Anemones, as well as Parthenocissus (Virginia Creeper) just starting to turn red. If it’s shrubs you’re after, we have Skimmia Rubella and Kew Green with lots of buds, Pieris in bud and flower, as well as some fabulous Yew balls, Pittosporum and Fatsia.

For pots and window boxes to look good through autumn and winter how about bright coloured cyclamen or heathers – Calluna and Erica gracilis.

Herbs are also a good option for pots and planters as well as in the ground; we still have a good range available if you come soon!

We aren’t stocking spring flowering bulbs in store this year, because social distancing measures would have made it impossible to house the stands in the shop and maintain your and our safety. Our suppliers have come up with a solution …. take one of their brochures (by the till) which lists all the bulbs they have available, and when you put in an order directly with them you will automatically receive a 10% discount.

For those of you without outdoor space, we always offer a great range of houseplants as well as the pots, composts and other sundries you need to create a stunning indoor display.

Are you ready for the autumn clean up? We have the items you need to make this task easier – including rakes, which are invaluable at this time of year as the leaves start to fall and the lawn needs a good going over.

Understandably, most customers choose not to linger in the shop at the moment … but if you do, you’ll see that we still have our range of pretty solar lights – ‘Starburst’ and ‘Dandelion’ (which comes in two sizes). They come into their own as the evenings get shorter.

And don’t forget to stock up with nuts and seeds to keep your garden birds well fed over the coming months. If you don’t already have a bird feeder in your garden, we have a range to choose from.

Whilst some of our suppliers are not quite back up to speed, none-the-less we do have a good range of pots and containers in stock including Eco Pots in black, dark and light grey and white which are made from recycled plastic. They add a contemporary look and feel and are lighter in weight than clay pots.

There is plenty to be doing in the garden in the coming months, and the Garden Jobs section below will point you in the right direction. As you know, for many years Sally has been the author of this section, but very sadly for us she has now retired, so it is down to me to try to fill her (very large) shoes! I’ve cheated this month, and flagrantly plagiarised most of the Garden Jobs section from the one she created last year 🙂

We all wish Sally well as she sets off for new adventures and some quieter time too. We had s lovely farewell cake and champagne party for her just before her final day with us, and I suspect she won’t be able to totally keep away from us. Keep an eye out and you might see her hiding behind a tree or shrub ….

On a final note, can I remind you that we will continue to follow very strict Covid secure guidelines in order to keep you and all the team here safe. As we move into cooler weather, the implications of perhaps having to queue to get into the centre, or stand outside waiting for your turn to go into the shop may become less palatable, but I’m quite sure you realise how important it is that everyone continues to adhere to the excellent systems we have in place.

Here’s to a glorious start to autumn. We all look forward to seeing you soon.

Warm regards

Karen and the rest of the team

Garden jobs

General garden maintenance

  • Keep deadheading plants all around the garden to prolong the flowering season.
  • Give evergreen hedges their final trim of the year, ensuring you do so after the sun has gone off them, or on an overcast day, to avoid scorch on the leaves.
  • Keep Camellias, Azaleas and Rhododendrons watered regularly as their flower buds continue to develop. If they go without water, the buds may drop in spring or fail to open. These ericaceous (acid-loving) plants should ideally be watered with rainwater but are fine to be watered with tap water if rainwater isn’t available. Note that over a long period ericaceous plants watered with hard water will start showing signs of chlorosis (yellowing of the leaves). Help to avoid this by mulching with ericaceous compost, and feeding with a suitable fertilizer (sequestered iron).
  • Herbaceous perennials which have outgrown their allotted space, or which look tired, can be lifted, divided and replanted before they die down. Water them well before doing so, and again when replanted. A good layer of mulch around the plants will help them establish swiftly.
  • Apply a good layer of compost or manure as a mulch around established trees and shrubs, including fruit trees, roses and wisteria. One aim of applying mulch is to trap in moisture, so make sure you have watered the ground well first. I always think of this process as ‘tucking them in for the winter’. Mulch helps moisture retention and, as the compost or manure breaks down into the soil, it acts as a slow release feed as well as helping improve the structure of the soil.
  • Start to clear away garden debris from beds and borders and from around containers.
  • Do, however, leave a pile of leaves, twigs and logs somewhere for overwintering wildlife.
  • Keep up general maintenance around the garden, removing dead and dying leaves from plants, pulling up weeds and generally cleaning to help prevent pests and diseases overwintering.
  • Sweep fallen leaves from lawns, patios and paths.
  • Cover ponds with a net to prevent leaves falling in and affecting water quality. Nets also protect fish from herons and other predators. Leave a small gap in the netting as an escape route for frogs and newts.
  • Remove any compost from your compost bin that is ready, and use this as a mulch all over your beds. You’ll need space in the bin for the leaves and prunings that you will be collecting over the next couple of months! Vegetable gardens will generate a lot of compostable material too.

Container gardening

  • Summer bedding containers can be prolonged by deadheading and feeding with a high potassium fertiliser such as tomato feed.
  • Containers can be replanted with a range of interesting leafy plants such as grasses, ferns, heuchera and small evergreen shrubs, as well as flowering pansies, viola, cyclamen and others, to see you right through until next spring. Remember to refresh or replace the compost, though, as the existing growing medium will be totally depleted of nutrients by now.
  • Pop some dwarf spring bulbs such as iris, crocus or dwarf narcissi under your autumn/winter container plants - it takes no time and will brighten the containers early next year.
  • For more permanent container planting of specimen plants and shrubs ask yourself whether you need to repot. This might be into a bigger pot or into the same pot by lifting the plant, pruning the roots and repotting with fresh compost. Know your plant and its requirements before doing this.
  • Think about planting a potful of bulbs - known as a bulb lasagne - to enjoy months of different colour from January right through to April or May. Larger bulbs such as tulips go at the bottom, narcissi or hyacinth at the mid-level and smaller bulbs such as dwarf iris or crocus at the top.

Pruning

  • Prune late summer flowering shrubs when the flowers have finished, including climbing and rambling roses.
  • Leave flower heads on macrophylla and lacecap hydrangeas to protect young developing buds below. They are best pruned in early to late spring.
  • Once lavender flowers have faded, cut the plants back with secateurs, within the green growth, not into brown wood. Doing this each year will maintain neat, compact plants and encourage more side shoots to grow.

Planting

  • Fill gaps in borders with late flowering perennials such as Sedum, Rudbeckia, Penstemon, Anemone, Salvia, ornamental grasses and much more.
  • As mentioned earlier, autumn is a perfect time to plant new shrubs, trees and perennials - the ground is warm and the roots have time to get established before getting off to a good start next spring.
  • Start planting spring-flowering bulbs now in beds or containers. Most bulbs can be planted from late summer into the autumn, leaving tulips until later. Bulbs should be planted at the right depth - general rule is a depth equivalent to two to three times their own height.

Watering and feeding

  • Ease up on feeding shrubs and trees with general fertilisers in containers, because soft new growth would be damaged in the winter months.
  • Keep watering plants in dry spells to reduce stress and the risk of disease such as powdery mildew.

Fruit and vegetables

  • Remove fallen fruit from around trees and shrubs before it rots.
  • Plant vegetables such as cabbage, cauliflower, broccoli, kale and more to enjoy through winter and spring.
  • Fix grease bands round the trunks of apple trees to trap the wingless female winter moths as they try to climb the trunk to lay their eggs, which would turn into bud eating caterpillars.
  • Use netting to protect leafy vegetables from pigeons.
  • Root vegetables can be lifted and stored, but leave parsnips and swedes in the ground to be frosted as this improves their flavour.

Herbs

  • ‘Tender’ herbs will continue to grow outside until the first frosts, and evergreens like rosemary, thyme and sage will remain above ground to use through to next spring.
  • Pot up herbs such as parsley, mint and basil for the kitchen windowsill to enjoy over the winter.

Lawns

  • It’s not necessary to water your lawn. Lawns which have browned over the summer will soon show green growth with a few days of rain.
  • As the weather begins to cool, the lawn will benefit from an autumn work over. It's worth spending some time and elbow grease in the next couple of months:
  • Remove old “thatch” (dead grass) and moss – use a springy rake to clear the congestion that has built up over the growing season.
  • Aerate – to improve drainage and help protect against a buildup of moss – use an aerator designed specifically for the job, or a fork.
  • Fertilise – a thin layer of lawn dressing (a combination of top soil, sand and fertilisers) or horticultural sand, should be raked or brushed to fill the holes created by aerating. This will improve drainage and avoid winter waterlogging, especially in heavy clay soils.
  • September is an excellent time to lay a new lawn with turf, or from seed. Take time to prepare the ground beforehand, giving it a good foundation.
  • Use a lawn weed killer to control perennial weeds before the weather cools.

Pests and diseases

  • Box tree moth is causing problems for many of our customers. If you use an insecticide, follow the instructions carefully and use it in the evening when beneficial insects aren’t around. Use a box tree moth trap and ensure that the plants are as healthy as possible by using a fertiliser such as Top Buxus.
  • Keep a continued vigil against slugs and snails, and make sure you don't leave places where they can settle in for the autumn and winter months.
  • Check for vine weevil in containers. Treat with appropriate chemicals or nematodes.

Wildlife

  • Keep feeders topped up for the birds and leave water out for them too. If we look after bird life with food and water, they'll help us in return by eating unwanted insects in the garden.
  • If thinning out plants in ponds, leave the debris at the side of the pond overnight so that wildlife can find its way back to the water.

Finally

I hope this all helps keep your outside space looking good!
Have a good month!
