In most zones, wildflower seed sowing season is in the fall, from mid-September to late November is best. This may seem counter-intuitive because after all most of us plant our potted perennials in spring to grow and flower for us in the summer. However, most perennial wildflower mixes contain varieties and species that require a cold stratification period in order to germinate.
Why Are My Wildflowers Not Blooming? After seasonal timing considerations, there are many other factors that can cause poor germination results for perennial wildflower seed. Before your rake or shovel ever hits the soil, here is what to pay close attention to… Improper Site Selection Areas with too much shade will not work.
In some situations, up to 1-year, prior may be needed to generate the proper percentage and balance of appropriate micro-organisms working in the soil. Improper Site Preparation & Cultivation Cultivating too deeply can disturb and bring up 10s of thousands of dormant weed seeds that have a much greater capacity to out-compete the wildflowers.
If adequate coverage is the goal, always default to more seed in a small area for better results. Control Competitive Weedy Grasses In Your Wildflower Patch Even if your site preparations are perfect, there will be encroaching weedy grasses that will move in to try to take over your wildflower planting. best wildflower seeds.

We're often asked "Can I sow wildflower seed onto grass?" Generally customers have an existing lawn or pasture which they want to enhance. The short answer is it may well not work (british wildflower seeds). You'll more often than not have a better chance of establishing a wildflower meadow area if you start from scratch.
There are other aggressive coarser grasses too, but PRG is the main offender as cultivars are always an important constituent of lawn or grazing mixes - bee friendly wildflower seeds. On the other hand, when you have a careful look at your grass you may be pleasantly surprised. People often find that they have a range of wildflowers they haven't noticed, or which just haven't had a chance to get going.
Preparation So, you have a promising site with what looks like fine grasses. What do you do to prepare it for overseeding with a wildflower seed mix? You need to really beat up the existing grass, to the extent that you can see up to 50% earth. You need to do this through a combination of scarifying and cutting.
Seed If you then decide to add some wildflower seed, source it from a reputable supplier and always check that not only does it include appropriate native species, but that the seed originates in the UK. "Wildflowers" can apparently mean different things to different suppliers! They need to be recently harvested and stored properly too.
You could at this point - particularly if you have a small area - decide it's all too much and pop some plug plants in instead. They're more expensive and you'll get less diversity, but they're definitely an option. Reckon on 5 per square metre, so a single one of these trays will cover 25 square metres.
The seeding rate is so low - reckon on around 1g per square metre - that you'll need to mix your seed mix with some peat free compost or sand to make sure you don't run out of expensive ammunition half way through sowing. The ratio of inert carrier to seed doesn't matter.
If you have a square 5m, X5m you know you will need around 25g of seed for that area. Scatter evenly across the area you want to seed. Do two passes if you can, one left to right and the other front to back. Once seeded, if its practical, give the area a light role to make sure the seed is in good contact with the earth.
Ten days after spraying, cut the dying vegetation as tight to the ground as possible and remove the cuttings. I only advise the use of Glyphosate as some other weed-killers do not break down on contact with the soil and so remain active to kill or weaken the future germinating seedlings.
For weedy areas, or where a lot of weed seeds have been allowed to build up in the soil’s seed-bank in the past, it is best to carry out a second spray when the area has greened up again, which can be several weeks later. Then undertake the seeding - free wildflower seeds. This will reduce the amount of weed seeds that will germinate from your soil along with your sown wild flower seeds.
but the rate of germination will depend on the level of moisture and warmth in the soil. Native wild flowers are hardy and winter sowing is fine but don’t expect to see germination until the ground warms up in the spring. Not all the species germinate at the same time, some are months behind others so there is always new things to spot when you inspect your wild flower area.
If you are not ready to sow your seeds yet don’t worry, as long as you ensure they are kept in the bag and stored in a cool, dark, dry place they will be viable for 12 months or more (wildflower seeds bulk). : dark areas under Sycamore, Holly or Beech trees etc.
Sow your seeds on the surface of the soil which has been revealed by the weed killing process described above. If you need to cultivate the ground because it is rather compacted, or you need to bring in soil, do this early to allow the weed seeds to germinate and then carry out the weed-killing procedure outlined above before seeding it.
This creates a great germination bed but it is not thick enough to prevent the seedlings getting their roots into the firmer ground beneath as they get bigger. This is useful because the compost layer tends to be quite light and dries out easily whereas the firmer ground beneath will not.
