Frequently Asked questions
How do I water Aralia Sun King?
After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Aralia Sun King a good deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example a one gallon pot would be watered until you count to 5 a three gallon pot would be 15 and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks.
How do I fertilize Aralia Sun King?
Feeding your plants is probably the single most forgotten part of growing healthy long lasting plants. We recommend feeding your Aralia cordata Sun King in the very early spring and again in mid summer after all new growth has hardened off and it begins to set flower buds. Bio-tone starter fertilizer is the best product to use at the time of planting. Our ideal fertilizer schedule for you to use is as follows. Apply an early spring fertilizer with a product such as Espoma Plant-Tone at the recommended rate this will give the plant a boost of nitrogen potash that will be needed for healthy foliage and stem growth. Follow this up with another early summer application of Espoma Garden-Tone, this will again provide the necessary nutrients to promote a flush of beautiful flowers. Espoma products are easy to use, just sprinkle around the base of the plant and water it in.
How do I mulch Aralia Sun King?
We highly recommend that you mulch your Aralia Sun King with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away which will compete with your new investment for water and nutrients. A 2 to 3 inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch. Its better to leave a one inch gap of space between the mulch and the stem or base of the plant.
How do I prune Aralia Sun King?
Remove the old flowers of Aralia Sun King as they become brown and unattractive. This procedure, called deadheading, encourages the agastache plant to produce new flowers, keeping your plant looking attractive throughout the season. Deadheading also prevents Aralia Sun King from spreading through your yard, as it can be an effective self-seeder when the dead flowers are allowed to dry completely and go to seed this would cause problems for your garden as the seedling would not be Aralia Sun King. Remove the brown stems and leaves to give your plant a healthier and more attractive appearance. Cut back Aralia Sun King to within 6 inches of the ground after it has finished flowering. In colder climates, cut it back as one of the last chores in your garden before the snow flies. In warmer climates, cut it back in the spring before it begins to bud. Cutting back will promote new growth, giving you a healthier plant with stronger stems.
