This magnificent producer features large heads of delicate soft pink flowers with white edges on show of a plant that are 12-14" high and wide is fine for 4" and 6" (and larger) container sales.Perfect for a southern gardener's dream, thrives even in soacking wet humidity and scorching heat of summer. While other plants look wilted even right after being watered, but not these Mavericks. A Compact, well branched, large flowered plant hold their giant spheres of blooms several inches above the rest of the plant. It has been proven for excellent garden performance in trials. Maverick is an annual Geranium, which is to say not a true Geranium at all, but a Pelargonium, known by some gardeners as Cranesbills. If you live in a frost-free climate, though, you can probably overwinter them successfully. If you don't, bring your favorites in for winter and put them in a bright window. 10 Seeds Per Package..
Flower Garden - Tips on Growing Geraniums From Seeds
Geraniums are light accumulators, the more light received, the faster the growth and earlier the flowering. DIF treatments may negate flowering.
- Optimum conditions for seedling development that begins the day the crop is sown until cotyledon expansion.
- Expect radicle emergence in 1 – 3 days.
- Cover: Cover seeds with a thin layer of medium sized vermiculite to maintain Moisture levels
- .Media: • pH: 6.4 – 6.5 pH levels <6.0 may promote shoot tip abortion and allow sodium, iron and manganese to becoming toxic. Symptoms of nutrient Toxicity will exhibit itself on the lower leaves.
- Light: Light is not necessary for germination. If utilizing a chamber, providing a light source of 10 – 100 foot candles (100 – 1000 lux) will improve germination and reduce stretch.
- Moisture: Saturated (5) for day 1 – 3. On days 4 – 8 reduce to moist (3). Beginning day 9, reduce moisture further to medium (2). Geraniums have a high oxygen requirement at the root level.
- Humidity: 100% until radical emergence then reduce to 40%.
- Dehumidify: Provide horizontal airflow to aid in drying down the media through evapotranspiration, allowing better penetration of oxygen to the roots.
- Temperature: 73°F (23°C). Thermodormancy, which causes erratic germination, is induced when temperatures exceed 76°F (25°C). Temperatures below 71°F (22°C) decrease the speed and uniformity of germination.
- Geraniums are relatively easy to grow from seeds. However, geranium seedlings are slow growing. Geranium seeds should be sown in early to mid-February to produce flowering plants for spring. Flowering occurs approximately 13 to 15 weeks after sowing.
- Soil less mixes, such as Jiffy Mix, are excellent germination media. During germination, damping-off of geranium seedlings can be a serious problem. Damping-off is caused by various types of fungi that attack the seedlings and destroy them. To discourage this, containers used for starting seeds should be clean and have adequate drainage. Previously used containers should be washed in soapy water, and then disinfected by dipping in a solution containing one part chlorine bleach and nine parts water.
- Fill the container with the germination medium to within 1/2 to 1 inch of the top. Firm the medium lightly, water thoroughly and allow it to drain for a few minutes. Sow the seeds in rows 2 to 3 inches apart and cover with about 1/8 inch of medium. After sowing, thoroughly water the medium by partially submersing the container in water. When the surface becomes wet, remove the container from the water and allow it to drain. The medium also can be moistened with a soft spray of water from a rubber bulb sprinkler or similar device.
- To ensure a uniform moisture level during the germination period, cover the container with clear plastic food wrap or a clear plastic dome. Set the container in bright light, but out of direct sunlight. Excessive heat buildup may occur if the covered container is set in direct sunlight. The temperature of the medium during germination should be 70 to 75 degrees F. With favorable temperature and moisture levels, the seeds should begin to germinate in seven to ten days.
- Remove the plastic covering as soon as germination occurs. Place the seedlings in a sunny window or under fluorescent lights. Fluorescent lights should be no more than 4 to 6 inches above the seedlings and left on for 12 to 16 hours per day. Using a well-drained commercial potting mix, transplant the seedlings into individual containers when their first true set of leaves appears. Handle the small seedlings by their leaves since the small, thin stems break easily. Insert seedlings to the base of the seed leaves (cotyledons) when transplanting.
- For best results, grow seedlings under fluorescent lights. (A standard fluorescent shop fixture with one 40-watt cool white and one 40-watt warm white tube works fine.) Plants grown in a window often become tall and spindly because of inadequate light. Ideal growing temperatures for geraniums are 70 to 75 degrees during the day and 60 to 65 degrees at night. Thoroughly water the geraniums when the soil surface is dry to the touch. If using a commercial potting mix containing a slow-release fertilizer, fertilization probably won’t be necessary. An application of a dilute fertilizer solution once every two weeks should be sufficient for those potting mixes that do not contain a slow-release fertilizer.
GARDEN HINTS: Harden or acclimate the plants outdoors for seven to ten days before planting into the garden. Initially, place the geraniums in a shady, protected location. Then gradually expose the plants to longer periods of sunlight. Plant the geraniums outdoors when the danger of frost has passed.
