  • 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, Summer Showers Mix is rated 3.5 out of 5 by 4.
    Rated 4 out of 5 by from I did not have any problems with germination, probably over 90% seeds germinated. The plants grew very nicely and looked beautiful in combination with petunias. However, I wish that they have more blooms.

    Rated 2 out of 5 by from Germination Fair There were only about 10 seeds in the packet. It would help if the number of seeds and germination percentage were printed on the catalogue info. I had only 3 seeds germinate.

    Rated 3 out of 5 by from ivy geranium I ordered 2 packets containing 20 individual seeds total. They were seeded in seed germination potting mix in 20 individual biodegradable pots kept moist. Unfortunately only 7 of the 20 seeds germinated. The seedlings are still small and have not yet produced flowers but look very healthy so far. I have now moved them to hanging baskets and added fertilizer spikes. I am disappointed in the 35% germination rate given the high cost including shipping but am hoping the survivors thrive and flower. I can always propagate more by cuttings once the plants are bigger to make up for the 13 that did not germinate.

    Rated 5 out of 5 by from Gorgeous! I loved these flowers! I recieved so many compliments on how great they looked. I really have nothing bad to say about them, just a couple of tips. 1. Germination was excellent, I only had a couple that didn't work; but I would still recommend purchasing more than you think you need, just in case. 2. They are fairly heavy feeders. I used miracle grow once a week and that seemed to be sufficient. 3. They took a lot longer to really take off and cascade in the garden than I would have liked. I recommend starting these a couple of weeks earlier than suggested on the packet. They do last a long time in the garden, though! The picture showing the geraniums in the boxes by our front door was taken in October!
