Fall is a little bit like a reverse spring. Everything is starting to wind down as winter approaches, and for a lot of gardeners, that’s a sad time. It doesn’t have to be, though; fall can be a time for laying the groundwork for spring plants and creating dazzling garden displays.
What to Plant
Fall planting can be tricky, largely
because the plants that prefer to be planted in the fall can vary widely
depending on where you live. However, if you live where it gets cold enough to
frost or freeze, you can bet on many of these being excellent candidates:
- Spring bulbs. Tulip, daffodil, Crocus, Allium, hyacinth, lilies, and even
Iris are awesome choices for planting in the fall. They don’t generally
need to be lifted, so they can be planted in those short days before the
first frost hits. You’ll reap the fruits of your labor when the ground
starts to warm up again.
- Perennials. A
huge range of perennials do great when planted in the fall. Bleeding
hearts, Rudbeckia, Sedum, Coreopsis, garden Chrysanthemums, Asters,
Hostas, and many others are not only great for end of year color, but will
reliably return year after year to put on a dazzling show.
- Shrubs. Looking
for some show-stopping fall color? There’s no better time to choose and
plant these kinds of shrubs than in the fall, when they’re at their best.
Look for shrubs that produce berries and sport lovely fall foliage like
Nandina, Viburnum, Pyracantha, and beautyberry. These will provide your
local neighborhood wildlife with a little extra forage, and give you some
extra fancy natural holiday decorations.
- Trees. Most
trees thrive when planted in the fall; it’s their best season! Planting
your young trees in the fall, well before your first frost, gives them
time to establish their roots without risking drying out. Not only do you
increase the odds that your trees will survive by choosing to plant them
in the fall, you’ll skip all the major maintenance required to nurse a
fresh, new baby tree through a hot summer. It’s really a win-win.
When to Plant
Timing is everything when
you’re planting in the fall. It’s not enough to ensure that the ground is
unfrozen and workable; you should also give your young plants time to grow and
spread their roots before they go dormant for the year. You can look up your
first frost date on a reliable gardening site like The Old Farmer’s Almanac.
Count back six to eight weeks and plan to plant your garden at that time.
Planting too close to a
frost can cause significant damage to your new plants, or even result in their
deaths from too much stress. After all, moving into a new neighborhood can be
tricky, even for a plant, and they need time to repair roots that have been
injured during the process. A few extra weeks to start going into dormancy will
help them come back strong in the spring.
Protecting Plants
For the most part, fall
plantings won’t need a great deal of protection as long as they’re planted in a
timely manner. What they will need is mulch, and lots of it. It doesn’t really
matter what kind of mulch you use, so long as it’s biodegradable and can be
piled on deep.
If your area sees snow and
freezing temperatures, go for about four inches of mulch per planting, evenly distributed
across the top. Wait to cover the crowns until you’re actually at risk for
frost, but the root area of the plant can be covered the day you plant it.
These kinds of mulches help the plant retain moisture and acts as insulation to
keep the warmth from the sun in the ground longer.
As your plants die back for
the year, mulch the entire area, making sure to carefully check tender plants
for new growth as temperatures rise in the spring. When you see those little
green sprouts popping up, uncover them (but leave the rest of the mulch) so
they can continue on their upward journey.
