About Unwins Seeds

Over 100 years of Unwins excellency 

Since the early 1900s, William Unwin and his family have been taking the UK gardening industry by storm, offering a wealth of high-quality seeds under the Unwins company name to help every green-fingered fanatic transform their dull and lacklustre garden into a gorgeous green space bursting with life! With over 100 years of experience under their belts, Unwin has formulated the perfect recipe to deliver the highest possible standard seeds to their customers, combining their own passions for gardening with generations of breeding, development, expansion and success. 

With a dedicated team and state-of-the-art germination laboratory, Unwins ensures that only the best goes into each packet of seeds they provide. This quality assurance starts at the grass-roots level (literally!) when varieties are carefully selected for their range, chosen for their good germination qualities and unique characteristics. Once chosen, the seeds are then tested for germination and purity by Unwins’ very own in-house laboratory team. But that’s not all: taking their dedication to quality even further, Unwins set their gemination standards way above the EU minimum to guarantee a high yield for consumers.

To ensure their seeds stay in their optimum condition before dispatch, Unwin store each packet of seeds in a temperature-controlled environment right up until they’re ready to be sent to the shelves. So, when it comes to quality, there’s really nothing quite like Unwin!

How do I sow my Unwins seeds? 

Whether you’re a professional gardener or budding green-fingered fan, if you follow these simple steps, you’re sure to get the most out of your Unwins seeds! 

Break up any large lumps of compost using your fingertips or gardening tools and use it to fill up your clean seed tray, module tray or pot while shaking the sides to settle the soil. Here’s the part that almost every amateur gardener gets wrong: don’t press the soil down with your fingers! Instead, use a ruler or a flat piece of wood to skim across the top of your container to remove excess soil and achieve a fully level surface.

Gently firm your levelled compost down with the base of another container, being sure not to pack it too tightly. Heavily water the soil in your container with a fine rose and let it drain for a few hours before you add any seeds into the mix.

After draining, sow your seeds thinly, leaving a generous gap between each seed. If you’re using a larger seed tray, you can scatter the seeds in but if you’re using a module tray or pot, carefully sow your seeds singularly. 

Once sown, cover your seeds in a light layer of compost, no deeper than the depth of the seed itself. Be sure to label your container at this point with the name of the seed and the date it was sown – it will make your life easier when it comes to harvesting! 

Cover your container with something that will let the sunlight through, such as clear glass, plastic or cling film. This covering keeps the humidity from the pre-watered soil within the tray, so you shouldn’t need to water these again. 

Place your sown containers on a flat surface in a nice warm spot with a decent amount of sunlight to allow your seeds to germinate. A great spot for this could be your windowsill or greenhouse if you have one! Be sure to check the seed packet for ideal temperatures and adjust the position of your container to suit this. For optimal germination, opt for somewhere your trays will receive a constant even temperature. 

Now you’ve done all the hard bits, all you have to do is keep an eye on your seeds and, before you know it, your little seedlings will start to appear above the soil! Once they become visible, remove the tray coverings to allow them to ‘breathe’. For a more hands-on approach (literally!), finger test the compost to see if it requires watering. Handy tip: if the soil sticks to your fingers, it’s damp enough, if it doesn’t, you should give it a little water! 

Gradually, and carefully, ‘harden off’ your plants and transfer them to a larger pot when they’re big enough to be handled by their leaf tips rather than their roots. In most areas of the UK, early June is one of the best times to plant out tender plants into permanent positions.
