Why is your neighbor’s garden blooming and lush, with fruit
tree branches heavy with a harvest, while in your own yard, a plant failed to
take root, a fruit shrub bears only a few scattered berries, and your trees
never produced the fruit you expected? It is quite possible that while you
chose the right plant, you chose the wrong place to plant it. A specialist who
has spent years working with and studying a wide variety of plants shares key
insights that anyone wanting their garden to thrive should keep in mind.
Different Results in Different Parts of the Same Yard
Even within the same climate zone, solar exposure and
microclimates can vary significantly. According to Eugenijus Popovas, head of
the online plant shop vitaflora.lt, creating a beautiful garden in Lithuania
requires understanding a few fundamentals—it is important to know not only what
and when to plant, but also exactly where in your yard to place it.
"The most widely used system for classifying plant cold
hardiness—both globally and in Lithuania—is the USDA (United States Department
of Agriculture) Hardiness Zone scale; Lithuania falls within the 5A–6B range.
However, if a plant originates from, for example, Japan, it may be sensitive to
sudden temperature fluctuations—especially when combined with exposure to
morning or southeastern sunlight. Therefore, such a plant should be positioned
in a spot where it remains shielded from the sun coming from these directions,
at least up to a height of one meter from the ground in late February or March.
If a sweet cherry tree is planted in an unsuitable spot, one fine spring, its
trunk may split on the southeastern side, about half a meter above the ground.
The cold rising from the soil meets the warmth from the sun, causing a crack to
form.
Another example is early vegetation. In Lithuania, snow
melts early on the eastern side of a house, but later on the western side;
consequently, plants on the eastern side wake up too early. *Actinidia* (hardy
kiwi) plants that wake up this early often perish due to May frosts rather than
winter cold. Apricots suffer the same fate,” explains E. Popovas, highlighting
nuances that many of us might never even consider.
What works for Vilnius may not necessarily work for Klaipėda
According to the expert, it is equally important to consider
whether a plant originates from a continental or a maritime climate. For
instance, the *Elaeagnus* (a relative of sea buckthorn) has recently become a
popular berry-bearing shrub in Lithuania, yet it favors a continental climate.
If planted along the coast, it may fail to prepare properly for winter and
suffer severe frost damage, whereas in Eastern Lithuania, it will overwinter
successfully. "The Canadian spruce—referred to by botanists as the white
spruce—is hardy down to temperatures as low as -50°C; however, it often suffers
severe sunscald on its southeastern side due to the intense sun during our
early spring. Other conifers, such as the Japanese umbrella pine, and even
rhododendrons, are also prone to such sunscald. Selecting the right spot for
each plant is crucial," explains a specialist who has spent many years
dealing in a wide variety of plants.
While the planting location may be less critical for certain
undemanding species, for most more interesting plants—or if you are aiming for
optimal results, whether in terms of yield or ornamental appeal—the choice of
site can play a decisive role. "For instance, smoke trees (*Cotinus*)
adapt excellently to infertile sandy soils and drought, but they struggle with
cold, dry winter winds blowing from the north or east. If planted in a windy
spot, they can suffer severe frost damage, often only regrowing from above the
snow line. The same applies to Japanese maples. In the breeding process, many
new plant varieties are developed with the goal of improving cold hardiness.
When creating interspecific hybrids between related plants, this can be
successful; however, when breeding occurs within the same species, differences
in cold hardiness are minimal—often amounting to just 1 or 2 degrees. For
example, apricot varieties with grand-sounding names like 'Northern Triumph'
are not necessarily significantly more cold-hardy than other apricot varieties.
In this case, choosing the right planting location is far more important than
the specific variety," explains the manager of vitaflora.lt—a site
nominated this year for the 'Favorite E-shop' award.
How to ensure plants successfully survive the winter
That said, selecting varieties that begin their growth cycle
or bloom later in the season is a better strategy for the Lithuanian climate
compared to choosing those that wake up or flower early. In this regard, the
specific variety does play a more significant role in successful growth and
fruit production. It is worth looking into varieties of nut trees or stone
fruits to find those that wake up later after the winter.
How should plants be prepared for autumn so that they are
best equipped for winter? Which autumn care mistakes are most likely to reduce
a plant’s resistance to cold and frost?
According to E. Popovas, the golden rule is that overly
meticulous preparation is more likely to cause harm than insufficient
preparation.
"Statistically, the average plant is more likely to
suffer from rot or 'sweating' (excess moisture) than from freezing. First,
check the plant's USDA hardiness zone, and consider whether it is suited to
windy or snowless locations. Also, ensure that the soil type matches the
plant's preferences—some plants thrive in sandy soil, while others prefer clay;
this will significantly influence how well they overwinter. For instance, a
yucca or an exotic ornamental grass will overwinter much more successfully in
dry soil than in wet soil. Autumn fertilizers are useful at the start; they
strengthen plants and lay the foundation for growth and fruiting in the coming
year. "It would be a mistake to fertilize in the autumn using spring
fertilizers that contain nitrogen," the expert notes, outlining the key
rules.
Furthermore, if you have carefully covered plants—for
instance, hybrid tea rose bushes—you should lift the coverings off the ground
as soon as a thaw begins. This allows air to circulate, preventing the plants
from overheating or waking up from their winter dormancy too early. If the
frost returns, the coverings should be lowered back down.
Planting: Spring or Autumn?
When is the best time to plant—autumn or spring? According
to E. Popovas, in countries where the ground does not freeze in winter—such as
the United Kingdom—the distinction between autumn and spring planting does not
exist; there is only "winter planting." This approach can sometimes
be successful in Lithuania as well, though with certain caveats:
"I have seen successful landscaping examples—for
instance, in the city of Vilnius—where large-scale planting took place in
December after the snow had been cleared. I have also heard of roses being
planted outdoors in the Kaunas Botanical Garden in January, as the ground had
not frozen that year. I sometimes joke that the best time to plant is when the
plants are in a state of complete dormancy. Just as a surgeon performs an
operation under anesthesia—effectively 'switching off' the patient—a gardener
employs a similar method: planting a dormant plant into dormant soil. There is
no need for watering or special care; nature itself supports the plant."
Plants with a very early growing season—such as currants or honeysuckle—are
best planted in the autumn; this allows them to establish and grow much faster
the following year. For most plants, however, it makes little difference
whether you plant in November or March—both are ideal months. If you are a fan
of exotic varieties that struggle to overwinter in Lithuania, it is certainly
better to plant in the spring; you might even keep them in pots within a
greenhouse until mid-May before moving them to their permanent location. The
climate can be quite unpredictable, presenting a different challenge each
year—be it drought, a severe frost in mid-May, or a winter without snow. Every
decade or so, an extreme winter inevitably occurs, and the plants that survive
are those that were planted with careful consideration for their specific
needs.”
