Elderberry seeds need the coldness of winter, or stratification, before they will germinate.
How do you cold stratify elderberry seeds?
Wrap the seeds in a damp paper towel and place it in a sealed plastic bag in the refrigerator for 60 to 90 days. Dried and stored elderberry seeds need extra treatment to germinate. The seeds must be soaked in water for three days before being stratified in a moist paper towel in the refrigerator for three months.
How long does it take elderberry seeds to germinate?
Seeds must be treated before planting for successful germination. Without treatment, elderberry seeds can take 2-5 years to germinate. Cold stratification for 60-90 days at 41F significantly reduces germination time1 but germination rate may still be low.
When should I start elderberry seeds?
The best time to plant elderberry seeds is in late fall. Cover the seeds in moist fertile soil. Additionally, keep watering during the first frost to ensure the soil does not dry out. To pot out, carefully pick out the seeds and sow them into trays of a potting medium at a depth of half an inch.
How do you start elderberry plants?
Plant elderberries in the ground at the same depth as their roots. Elderberries are shallow-rooted, so keep them well watered through the first growing season. Aim to keep the soil consistently moist but not soggy, applying irrigation whenever there is less than an inch of rain in a week.
Do elderberry seeds require stratification?
Elderberry seeds have a thick, tough seed coat and what botanists call “natural dormancy.” This means that the seeds must obtain optimal conditions before waking up from their deep sleep. In the case of elderberries, the seeds must be stratified twice.
What happens if you dont cold stratify seeds?
In nature, these seeds won’t sprout without the cold period because if they did sprout early (right before winter) then they would die, so this cold period which signifies winter, allows them to sprout in the spring when temps warm up without the danger of winter freezes killing them just as they’ve sprouted.
Are elderberries easy to grow from seed?
Elderberry seeds need the coldness of winter, or stratification, before they will germinate. Germination is tricky and plantings will sometimes produces nothing even though the same methods are used from year to year. Elderberry seeds have an extremely hard outer coat. This is a factor contributing to low germination.
Can you grow elderberry indoors?
Elderberries grow best if you plant them from a nursery seedling or bare-root or propagate them from a mature plant rather than from seeds. Growing elderberries indoors is possible, but these plants require full sun throughout the day to produce berries. They are one of the best shrubs for containers in full sun.
How many years does it take for elderberry to produce fruit?
two to three years
If you want to grow elderberries for their fruits, plant at least two different varieties that are known to bear safe, edible berries. Keep the plants no more than 60 feet apart. Berries may take two to three years to appear.
Does elderberry fruit the first year?
Elderberries will grow on plants the first year you plant them, but they take two to three years to fully fruit depending on how they were sourced. A healthy elderberry plant can live up to 60 years.
Do elderberries produce the first year?
Like most fruit plants, elderberries require well-drained soil with a pH between 5.5 and 6.5. The root system is very fibrous and shallow, so cultivation should be shallow. The plants come into full production after 3 to 4 years, with berries maturing in late August to early September.
Will elderberry survive winter?
Once established, blue elderberry also grows well in drier conditions but may go dormant in late summer or early fall as soil moisture levels wane, and green up again with winter rains. In most areas, however, blue elderberry typically goes dormant in winter.
Where is the best place to plant elderberry?
Elderberry prefers sun to part-shade; they don’t want to be overly scorched by the sun in super hot and arid locations. Choose a nice part-sun to part-shade section of your garden with well-drained and fertile soil. Once you have a nice spot in mind, be sure to test the soil pH of your intended planting location.
What grows well with elderberry?
Elderberry Companion Plants
Some of our favorite plants to grow with elderberry are phlox, bee balm, winterberry and blueberry shrubs. Try and plant the other plants at the same time as the elderberry, because these shrubs do not like their roots to be disturbed once established.
How often should you water elderberry plants?
Elderberry plants need approximately 1 inch of water each week, from bloom time to the end of harvest. If you are not getting enough rainfall, plants should be irrigated for optimum plant growth and fruit production. Also, if you are having prolonged dry periods after harvest, keep your plants well-watered.
What seeds benefit from cold stratification?
Common varieties that require cold stratification for spring planting:
- Milkweed (Asclepias)
- Lupine (Lupinus)
- St. John’s Wort (Hypericum perforatum)
- Prairie Coneflower (Ratibida)
- Prairie Violet (Viola pedatifida)
- Pincushion Flower (Scabiosa)
- Marsh Marigold (Caltha palustris)
- Perennial Sunflowers (Helianthus)
What seeds benefit from stratification?
Common plants that require stratification include apples, sloes, hawthorns, plums and acorns, but also smaller seed from herbaceous perennials such as aquilegia, lavender, sage, sedums, perennial sweet peas, wild rose and hops. One way to break this dormancy is to leave it up to nature.
Do you water seeds during stratification?
When planting moist stratified seed, it is best to water the area for one to two months after seeding. Seed may revert to dormancy if it does not receive rain or moisture within a certain number of days after planting.
Should I stratify in fridge or freezer?
Place into a labeled, dated Ziploc bag. Place the bag into the refrigerator–in the back or at the bottom where it’s coldest, but not in the freezer! Remove after the recommended time (see each seed description for the time required to break dormancy).
Can you cold stratify in the fridge?
There are exceptions, but most seeds that require cold stratification require cold, moist conditions in which to stratify. Just putting the seed packet in the fridge won’t do the trick: there’s no moisture! Your seed packet will specify how long the seed needs to be cold stratified.
