Marge is a hardy hybrid of American and European elder. It is vigorous, self pollinating, disease resistant, and doesnt sucker all over the yard. It's berries are 3x bigger than most varieties which makes for easier stripping of the berries! It stays compact and can grow 8-12ft high. What's not to like? This variety is the only elderberry i grow! I DO NOT USE ANY CHEMICALS GROWING ELDERBERRY! I have an organic property in Gilbertsville, Pa.
When you receive your elderberry cuttings the first thing you want to do is soak them in well water or distilled water for 24 hours. Fill a large glass container such as a canning jar with the water and place your elderberry cuttings in the water, angle side down.
Place the jar in a cool location away from direct sunlight and let sit for 24 hours. After the 24-hour soak period it's time to prepare the elderberry cuttings for planting.
Remove the elderberry cuttings from the container of (well or distilled) water and place them on a paper towel to air dry for a couple of minutes. Empty a small amount of rooting stimulant into a clean bowl. Dust the angled end of the cutting with rooting stimulant and tap the cutting against the side of the bowl to remove the excess. PS - IVE HAD HIGH PERCENTAGE RATE NOT USING ANY ROOTING STIMULANTS!
Plant up to three elderberry cuttings in each large pot by carefully inserting the angled end dusted with rooting hormone into the soil. Be sure to leave the top nodes located near the flat end of the cutting exposed as this is where the new elderberry plant will develop leaves.
Root your elderberry cuttings indoors in an unheated, sheltered and shady spot, be sure to check the pots weekly to ensure that the soil is still moist, and water as needed. Keep the pot tented, as shown above, until the cuttings have rooted well. Placing the pot in a tray to collect any water that runs out of the pot is also a good idea. After 10 to 12 weeks the plant will be ready to transplant.
The best permanent location for an elderberry bush is one that receives at least 6 hours of direct sunlight per day and allows the elderberry to get about 10 feet tall and 6 to 8 feet around. Elderberry is one of those plants that "sleeps, creeps and then leaps", meaning that it spends most of its first year establishing a good root system, begins to take off on the second year, and then grows vigorously during its third year. You can control the size of your elderberry bush by pruning away the old third year wood and removing any canes that are growing where you don't want them to be.
