Leave the Leaves: Let's Clear it Up!
At this time of year, we see the same question in many forms:
- Should I clean my garden now?
- What is your opinion on "leave the leaves?"
- Is it better to clean up your garden in the spring or fall?
In essence, many gardeners seek guidance on what the best move to make is for cleaning up their gardens. In reality, the "best" decision can be different for different gardeners. These are the considerations we want to bring to mind:
Reasons to Leave Plant Debris/Leaf Litter
- Create a haven for insects and wildlife to overwinter in
- Provide a layer of organic matter/natural mulch in your garden beds
- You have more time for garden chores in the spring
- Plants with sensitive crowns may be better if left alone over the winter and managed in the spring
- Late blooming plants may still be in flower, or ornamental seed heads provide winter interest for your garden space
If You Do "Leave the Leaves"
- Mulch or shred leaves that will be left on the lawn to break down. This causes them to release nutrients into the soil at a faster pace and gives plants below a chance to find sunlight in the spring
- If unable to mulch your leaves, do not leave more than an inch or two of fully intact leaves. Thicker leaves will hold moisture and encourage disease or smother plant material below. They are also slower to break down and will need to be managed in the spring.
- Monitor for pests like jumping worms in leaf piles
- Monitor closely next growing season for signs of pest and disease and manage as soon as possible!
When you SHOULD clean up in the fall:
- Your garden has experienced fungal disease or significant pest damage
- Sanitation is a least-toxic method of control when it comes to managing garden pest problems.
- Many fungal spores and vegetable targeting insects will overwinter in the leaf pile alongside beneficial insects. If you have had a particularly damaging year, it may be in your best interest to remove that leaf litter and plant debris from your property.
- There are plants (perennials & ornamental grasses, in particular) along your foundation or in other areas of your property that could encourage undesired rodent damage?
- There's no doubt that rodents and small mammals need a home to overwinter in, but by removing possible shelters early in the fall, they will be encouraged to move elsewhere before the real cold sets in.
- Trees or shrubs on your property have experienced girdling or rodent damage before.
- Building up leaves to insulate plants can be great! However, if past trials of this have resulted in damage to the stems or trunks, you may want to reconsider this method.
Keep Your Jack-O-Lanterns Fresh!
Everyone loves to carve a pumpkin! Jack-O-Lanterns (which were originally carved from turnips), are a festive tradition that many of us enjoy!
And whether you're a skilled artist or a spirited novice, keeping your jack-o-lantern fresh for the season is important! Learn about the traditions of the Jack-O-Lantern and how to keep yours well preserved at the links below!
Plant Highlight: Monkshood
Monkshood, also called helmet flower and wolfsbane, is a deer-resistant non-aggressive, non-invasive non-native perennial that flowers in late summer-October here in Connecticut. The flowers are a striking deep, dark purple blue on upright spikes. It can used in cut flower arrangements. This is a good plant for shade conditions.
Wildlife Highlight: Birds Are On the Move!
The Palm Warbler is a small warbler that forages primarily for insects. They will eat seeds and berries if available. These little birds migrate through our area in the spring and fall! Like a Phoebe, they are known for their characteristic tail wagging when they rest.
Late September is the beginning of migration to warmer climates of many species of birds that pass through Connecticut. Cornell University has many helpful fact sheets and other bird information tools that cover birds either breeding in or migrating through the North.
