Planting Geranium Karmina:
We suggest when planting your newly purchased Geranium Karmina plants that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Aster divaricatus does prefer drier soils in the winter so if there was ever a plant that we would recommend not adding topsoil or compost this is one. Bio-tone starter fertilizer is a great starter fertilizer that provides plants with mycorrhizae fungus. It is a naturally occurring beneficial fungus that colonizes on the new growing roots of plants. It creates a barrier between the roots of the plant and fungus and pathogens that can cause root rot. We love this product and use it on all plants we install in our own gardens. Bio-tone is a gardener’s best friend and can help guarantee your success.
Watering Geranium Karmina:
After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Geranium Karmina 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. Once established it will require very little additional water.
Fertilizing Geranium Karmina:
Feeding your plants is probably the single most forgotten part of growing healthy long lasting plants. We recommend feeding your Geranium Karmina in the very early spring and again in mid summer after all new growth has hardened off and it begins to set flower buds. Espoma 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 Flower-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. Be careful with products such as miracle-grow as these products can burn newly planted plants when not used at the recommended rates. Slow-release fertilizer can help prevent rapid soft growth that is vulnerable to diseases and insects.
Mulching Geranium Karmina:
We highly recommend that you mulch your Geranium Karmina 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. Once establish Geranium Karmina will reduce the amount of mulch your garden will require so this is truly a plant that will return your investment over time.
Pruning Geranium Karmina:
Remove the old flowers of Geranium Karmina as they become brown and unattractive. This procedure, called deadheading, encourages the geranium plant to produce new flowers and keeps your plant looking attractive throughout the season. Deadheading also prevents Geranium Karmina 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 Geranium Karmina. Remove the brown stems and leaves to give your plant a healthier and more attractive appearance. Cut back Geranium Karmina to within 2 to 3 inches of the ground in the late fall. 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.
When to Prune Geranium Karmina:
Geranium Karmina reliably blooms on the seasons new growth, so prune to the ground during late winter or very early spring before growth starts. Fall pruning, especially in colder climates, can result in a quick flush of new growth that prevents dormancy and makes winter freezes potentially deadly.
