  Pruning Roses

  Pruning roses in September prepares the plants for winter and promotes healthy growth in the new season. It is important to use sharp, clean tools such as pruning shears. Always cut at an angle above the eye (the bud), which faces outwards. This prevents rot. The height of the cut depends on the type of rose. As a general guideline, you can use the following:

  • Shrub and hybrid tea roses: approx. 3-5 buds above the ground.
  • Climbing roses: approx. 10 buds above the ground.
  • Wild roses: shorten by half.

  Also remove old, woody shoots and diseased shoots.

  Dividing perennials

  Vigorously growing perennials such as delphiniums or Phlox, and spring and early summer flowering plants in general, can be divided in September to rejuvenate them. Here's how to divide them: Carefully dig up the plants. Then, carefully remove the soil around the root ball and any old leaves. For large plants, you can use a sharp knife or spade to divide the root ball into several sections. Smaller plants can simply be divided by hand. Make sure that each section has enough roots and shoot buds. Now plant the new sections in a similar location to the parent plant. Place the plants in the soil, press it down firmly, and water thoroughly. Your garden pond will also benefit from a thorough cleaning and maintenance in September. © ELEO Maintaining and Cleaning Your Garden Pond September is also a good time to spruce up your garden pond. Remove leaves and debris, as these decompose and can affect the water quality. Trim back pond plants and remove dead shoots. Remove algae if they have multiplied excessively and are clouding the water. Clean the pond filters and vacuum up any sludge. This is especially important if your pond is older. Finally, you can stretch a pond net to keep falling leaves out of the water. As soon as the leaves start to fall, you can use them to create a compost pile. pixabay.com, NoName_13 Creating a compost pile Since the trees will be losing more and more leaves in the coming weeks, September is the ideal time to start a compost pile and use the fallen leaves. To create a compost pile, proceed as follows: Choose a sheltered, partially shaded location directly on the ground – concrete is not ideal. Ideally, use a special compost bin. Now, alternate layers of brown (leaves, straw) and green (grass clippings, kitchen waste such as vegetables and fruit) materials. For faster composting, turn the compost regularly.

  Important: Meat, fish, bones, and diseased plants do not belong in the compost.

  Planting Hardy Plants

  September is the ideal time to introduce hardy plants into your garden. They will then have enough time to establish roots. Particularly beautiful, hardy perennials include:

• Bleeding Heart (Dicentra spectabilis)

Coneflower (Rudbeckia)

• Catmint (Nepeta cataria)

• Daylily (Hemerocallis)

• Lilac (Syringa vulgaris)

• Hydrangea (Hydrangea)

Use trellises such as perennial supports and Ranko belisks to support your new perennials as they grow in the new season – so that they can grow healthy and lush.
