    Hi-wasn't sure if this topic should be in another area..but anyway

    I wanted to grow a large swath of different cornflower varieties e.g pink, white, 'black', blue and so forth.

    Does anyone have any tips on how to get the best results? I've read that it's best to plant them outdoors in early April.(I'm based in Harrogate). Do they need particular soil type and is there any diseases i need to keep an eye on?

    Thanks

    Hi Shane,

    I think April should be fine for you being in North Yorkshire, perhaps one of the members from that area such as @clueless1 may give you more localised info.

    I don't think that they prefer any specific type of soil but being annuals from cornfields etc they prefer for it to be on the poorer side so I wouldn't feed them.

    What you could do is make your first sowing in April then one more about a month later in between the ones you've already sown. This will give you a longer flowering period.

    Hope you're gonna share some piccies when they're in flower :) I love cornflowers and all the other traditional cottage type flowers.

        I think poppies need winter cold to germinate, so should be sown in autumn. Cornflowers are fine sown about now. Maybe not what you're after, but you can get annual cornfield mixes including e.g. corn marigold and corn cockle as well pretty cheaply. Plus you can obviously mix in other suitable annual seeds as well.

        "Cornflower Growing Guide
        [​IMG]
        Crop Rotation Group

        Miscellaneous ●

        Soil
        Any good garden soil.

        Position
        Full sun.

        Frost tolerant
        Young cornflower seedlings can tolerate freezing temperatures, so seeds can be planted in early spring, or in the fall where winters are mild.

        Feeding
        Fast growth is encouraged by mixing a balanced organic fertilizer into the soil before planting.

        Companions
        Cornflowers have an upright posture that helps them fit in tight spaces. Intersperse throughout the garden, as cornflower nectar is unusually sweet, and thus a preferred food source for many beneficial insects.

        Spacing
        Single Plants: 7" (20cm) each way (minimum)
        Rows: 7" (20cm) with 7" (20cm) row gap (minimum)

        Sow and Plant
        Sow cornflowers from early to mid spring for early summer bloom. Also sow in fall in climates with mild winters. Plant seeds in soil or in containers about 2 inches (5 cm) apart and one-half inch (1 cm) deep. Thin to 8 inches (20 cm) apart in all directions.
        Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.

        Notes
        Rice-size cornflower seeds are much loved by goldfinches and other small seed-eating birds.

        Harvesting
        Cornflowers make good cut flowers. Pull up the plants in mid to late summer, when they no longer look attractive.

        Troubleshooting
        Cornflowers may be nibbled by rabbits, especially in early spring when other food is scarce.

              They were the first plants I grew. Was about 8 years old and would go down the garden every day to check on their progess, even the day after being sown, hoping for some kind of minor miracle. Absolutely love them.

              Hope you find what you want and get the results you hope for.

                oh great :) They are really lovely and so English. I planted mine a few days back. I had to throw them inbetween the Tulips as they have taken over at the minute. Hope they flower. Thanks mowerman.

                  I'm trying to grow some cornflowers in a cell seed tray in the kitchen! I was hoping to be able to share some with other members at Shineyland & give some to the plant stall, I'm not sure it's going to work but it's worth a try :noidea:. After reading this thread maybe I will sow some directly into the garden too :dbgrtmb:

                    Interested to see how yours turn out...

                    I'm about to sow some wildflower mixes on some of the poorer areas of our "grass". Some will be broadcast sown, others in half-toilet-roll modules, to be planted out later. This method will help on the steep bank, where I'm afraid any rain will wash the seeds to the bottom of the bank!

                    We will have to compare pictures later in the season :spinning:

                      btw way mower, do i need to keep the seeds constantly moist? It's been sunny here in Leeds, past few days , as well as windy, so, the soils a bit dry. I was wondering if this, 'keeping them moist' is a general rule when planting most types of seedlings outside? If anyone can help that would be great. Ta
