Geraniums may be grown from seed may be sown early indoors and transplanted outside after frost, or grown from potted plants.

Sowing Seed Indoors:

  • Sow indoors 10-12  weeks before last frost  
  • Sow seeds ¼ inch deep into individual containers filled with seed-starting formula.
  • Keep the soil moist at 70-75 degrees
  • Seedlings emerge in 7-21 days
  • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
  • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
  • Transplant hardened-off seedlings to the garden after the frost.
  • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

Planting in the Garden:

  • Select a location in full sun with good rich moist, well-drained organic soil.
  • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Plants should stand 12 inches apart in the garden.
  • Set level with the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand leaving a slight depression around the plant to hold water.
  • Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
  • Use the plant tag as a location marker.
  • Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. 
  • Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
  • Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1 of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
  • Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.
  • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Flower-tone, as higher rates may encourage root rots.
  • Deadhead spent flowers to prolong blooming.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Remove plants after they are killed by frost in fall to avoid disease issues the following year. Geraniums may also be brought indoors and grown as houseplants over the winter.
  • Geraniums are perfect for beds, borders, walkways, and containers. Ivy-leafed geraniums cascade, making them ideal for hanging baskets and windowboxes.
  • Geraniums may be grown as houseplants over the winter in a sunny location. Over time they may become woody with the flowers smaller. Take stem cuttings to propagate new plants.

Geranium, Rozanne is rated 4.4286 out of 5 by 7.
Rated 1 out of 5 by from Didn't overwinter. Bought several geraniums last autumn on sale and repotted right away. When the first frost came moved the pots into a sheltered area on my screened in patio. Perennials are expensive so when you have your garden planned in stages and the plants don't re-bloom as anticipated it is more than disappointing - its downright discouraging.

Rated 5 out of 5 by from Excellent blooms first season! I was fairly skeptical about this plant, because it arrived so scraggly and didn't seem to grow much after I planted it. But around the middle of July, it took off like a rocket and now it's covered in blossoms! It's a small plant, so I'm definitely thinking about ordering more. It looks fantastic in the front of my perennial garden and is doing great in full sun. I have it lightly mulched and haven't needed to water it much at all this summer. I have it planted in front of my lemon balm and I recommend planting it near a plant with full foliage, as that's one thing it lacks. But the flowers are delightful and I highly recommend it!

Rated 5 out of 5 by from Wonderful in between rose bushes! This plant is a great performer! I puchased 4 and planted them between my rose bushes. They bloomed all Summer long. They are very drought tolerant. I was impressed with the size and quality of the plants when they arrived.

Rated 5 out of 5 by from Rozanne Geraniums Firstly, this plant was given to me as a gift and now I have several of these lovely flowering geraniums around my garden via purchase thru Burpee. Hearty plant, love the color, and the bushy foliage of the plant is a really nice green addition to my garden even after the blooms die off.

Rated 5 out of 5 by from One of my all-time favorite plants I discovered "Rozanne" several years ago and have more than a dozen of these wonderful plants in my gardens. My house faces north, so I have to use plants that will thrive in mostly shade for the beds next to the house. My "Rozanne" geraniums have flourished there and I now have a solid border of them across the front of my house. This summer, I planted several more in a location that was recently cleared and is much sunnier. The plants that were in the sunniest spots struggled along, while the ones that received more shade have grown in nicely. So it seems that, at least in my part of Zone 6, they prefer part shade. Visitors and passers-by often comment to me on how beautiful these flowers are.

Rated 5 out of 5 by from Geranium - Rozanne This is the first year for this plant in my garden, and I found it to be a great addition to my collection of perennials. It was easy to grow, and it started blooming rather early in the summer and continues to bloom profusely. The flower color is very eye-catching and looks great with the nearby pink roses.
