Why should I grow vegetables from seed?
Growing from seed is the lowest cost and most rewarding method of raising your own plants. Whether you are sowing into seed trays and propagators, or directly into the ground, there is nothing more satisfying than a glorious display of colour and scent, or a bumper crop of tasty fruit and vegetables, that you have grown yourself.
There are two methods to start your seeds growing:
- In a greenhouse/conservatory or indoors on the windowsill (usually known as half-hardy seed), then potting on and planting outside at a later stage when the danger of frost has passed. There are lots of easy to use indoor seed propagation products available.
- Directly into the ground where they are intended to grow – the quick, easy and very low-cost way to fill your garden with vibrant flowers and tasty vegetables.
Where can I grow vegetables?
You might be surprised to know that you really don’t need a big garden to start growing your own vegetables – any space will do as long as it’s a sunny open spot.
If you have a garden or allotment, be it big or small, you can make a dedicated vegetable patch. Alternatively, you can grow within a mixed bed with flowers, in pots on the patio, in outdoor window boxes and even your kitchen windowsill will provide you with a lovely crop of herbs, tomatoes and peppers.
If you are short of space then use large pots and containers. Tomatoes can be grown in hanging baskets, runner beans grown-up ‘wigwams’ of bamboo canes and even pumpkins and aubergines can now be grown in pots!
Raised beds also provide an attractive and practical alternative to growing in the garden soil due to the fact you can select the positioning, Eg. A sunny spot on the patio. These will also help provide earlier and longer cropping of your veg.
Most vegetable seeds can be sown directly where you want them to crop. However, keep a watchful eye on the weather and wait until the soil has warmed up to at least 6°C.
Tip! – Plant your veg in old buckets, sinks, or wheelbarrows. Flea markets, car boot sales, and charity shops are perfect for picking up cheap and unusual planters.

Starting to grow your seeds
There are four easy ways to start growing your own; Packeted Seed, Seed Mats, Seed Tapes or Seed Kits!
- Packeted Seed – Fill a seed tray (or other container) with good quality compost such as Suttons All Purpose Compost leaving a gap of about 1cm at the top of the container. Scatter seed evenly, pressing it gently into the surface. Cover larger seeds with a light covering of compost. Then gently water your seeds and keep them in a warm, draught-free spot indoors (see back of packets for more information). Items such as salad leaves, beetroot, carrots, parsnips etc. can be sown directly where they are to grow.
- Seed Mats – A very easy way to starting your seeds growing indoors. Fill a container with good quality compost such as Suttons All Purpose Compost leaving a gap of about 2cm at the top. Simply lay your seed mat on the compost and cover lightly with compost. Gently water your seed mats and keep them in a warm, draught-free spot indoor (see back of the packet for full instructions) No thinning out of the seedlings as they grow is required as the seed is pre-sown for you, which leads to healthier, stronger plants as there is no disturbance to the roots.
- Seed Tapes -The easiest way to grow your vegetable seeds is to use our groweasy seed tapes and mats.
With a stick or tool handle, make a ‘drill’ or groove in your garden soil, and then simply lay your tape along the groove and cover with soil. Water the ground well. No thinning out of the seedlings as they grow is required as the seed is pre-sown into the tape which leads to healthier, stronger plants as there is no disturbance to the roots. See back of packets for full information.
- Suttons Jiffy 7® Seed Kits – Add warm water to the tray to expand the Jiffy® pellets, pouring off any excess once they are fully expanded. Plant 2-3 seeds in the centre of each Jiffy® pellet. Remove excess seedlings so you are left with just one per Jiffy® pellet. Grow your seedlings until they are ready to plant out. See seed kit packaging for full information on this very easy and quick way to produce your own vegetables. Some seeds may need to be started indoors or undercover (excluding seed tapes) please check individual packets for full sowing details.
Giving your seedlings room to grow
When the seedlings are large enough to handle, transfer to larger pots (8cm (3″) is usually the best size to use for this job) or into trays of compost to allow them to grow and develop more easily.
Do this by gently holding the top leaves and carefully ease out the seedlings from their original growing container (if using a seed kit remove the pellet and seedling together). Use a pencil (or even a teaspoon handle) to create a hole in the ‘growing on’ pots or containers. Place your baby plants into prepared holes taking care not to damage the roots.
Gently firm the compost around the roots and stem to leave the first leaves just above the surface. Water gently keep them in a warm spot indoors and protect from direct sunlight for the first 3-4 days.
Outdoor sowing for hardy seeds
- Prepare your seedbed in a sunny, open spot (March-May for most vegetables).
- Dig over and leave until the first weeds appear. Pick out these weeds and rake the soil to a fine crumbly surface.
Tip! – Digging a good quality general garden fertilizer or compost into the weed-free soil, before sowing the seeds, will give you a better crop of tasty vegetables.
3 easy methods to sow your seed:
- Broadcast Method: Scatter your seed on the surface of the soil in a circular motion, to cover the space available. These can be raked into the surface or covered lightly with compost and pressed down gently.
- Sow in rows: This method is useful with fine seeds such as Carrots. Sow thinly in a pre-marked ‘drill’ (shallow groove). The seedlings may need to be thinned later to allow enough space for your veg to grow. Larger seed such as Beetroot is easier to handle and can be planted singly along a ‘drill’- this reduces the need for thinning out later on.
- Seed Tapes: The easiest way to grow your seeds. In a pre-marked ‘drill’ simply lay your tape along the groove and cover with compost. No thinning is required which leads to healthier, stronger plants as there is no disturbance to the roots.
Whichever method of seed sowing you choose, water the seed beds with a watering can that has a fine rose. This will prevent a wash effect that would disturb the seeds.
When the seedlings are large enough to handle, thin out (not required if using seed tapes or mats) to the distance shown on the pack. Use any surplus seedlings to fill the gaps that might appear leaving well-spaced plants (see back of packets for information on the correct spacing of seedlings). Always water transplanted seedlings. Remember to keep plants watered and fed as required.
Patio Containers & pots
You can achieve a glorious selection of vegetables on your patio using a variety of containers. Anything from stone urns and wheelbarrows to old boots and tin cans can hold plants; so long as they have good drainage (placing small stones or broken pots in the bottom of your container will help here). Then fill with good quality compost and plant up as required, once all danger of frost has passed.
Don’t forget to water containers regularly especially during hot weather. Apply a good quality liquid fertiliser weekly or add a slow-release fertiliser to the compost along with water retaining gel granules to help reduce the need for more frequent watering.
Get the most from your vegetable plot
If you are lucky enough to benefit from a garden or allotment and would like to get the most from it we recommend that you move each section or family of vegetables within your plot each year – this is called “crop rotation”. This will help reduce pests and diseases, maintain soil fertility and nutrients, and reduce the need for fertilisers.
When planning your plot you will firstly need to decide on the vegetables you want to grow (and eat), giving consideration to the amount of space you have available. If possible you should aim to produce vegetables all-year-round without shortages or excess. The area chosen should be divided into three equal sections.
An example of a 3-year crop rotation plan
|Manured with Dung or Compost||Fertilisers and Lime*||Fertilisers|
|Section 1 of Plot||Section 2 of Plot – Brassicas||Section 3 of Plot – Roots|
|Tomatoes||Seed bed for Green Crops|
|Succession Crops||Succession Crops||Succession Crops|
|Fertilisers and Lime*||Fertilisers||Manured with Dung or Compost|
|Section 1 of Plot Brassicass||Section 2 of Plot – Roots||Section 3 of Plot|
|Seed bed for Green Crops||Tomatoes|
|Succession Crops||Succession Crops||Succession Crops|
|Fertilisers||Manured with Dung or Compost||Fertilisers and Lime*|
|Section 1 of Plot – Roots||Section 2 of Plot||Section 3 of Plot – Brassicas|
|Tomatoes||Seed bed for Green Crops|
|Succession Crops||Succession Crops||Succession Crops|
*Only lime if soil is known to be acid
Section 1 – If you can, dig in well-rotted manure or garden compost in the autumn or early winter – it’s not essential but it will give you better crops; in the first year grow Beans, Leek, Lettuce, Onions, Peas, and Tomatoes.
Section 2 – A general garden fertiliser should be applied 10 to 14 days prior to planting or sowing. This area can then be used for growing Broccoli, Brussels Sprouts, Cabbages, Cauliflower and Kale.
Section 3 – Apply general fertiliser prior to sowing and planting. The crops to be grown in this section include Beetroot, Carrots, Parsnips, Potatoes, and Swedes.
As above moving all crops on one section.
Crops and treatments are rotated once more so that all sections have grown all plants over a three year period.

Handy hints and money-saving gardening tips
- Beans can be soaked overnight and placed on damp cotton wool or blotting paper to shoot. This will speed up the germination time.
- Seed trays are low cost and re-usable however you can start your seeds in something as simple as a margarine container – just remember to add holes for drainage.
- ALWAYS choose a good quality seed compost for the very best results
- You can always use spare seedlings of lettuce or onion, for example, in salads.
- Seed swap with friends and family. If you each grow a different variety you can exchange the seedlings.
- Lollipop sticks make cheap and sturdy seed labels.
- Store spare seeds in a sealed container with a few grains of rice to keep them dry.
- Make fortnightly sowings of salad leaves to maintain fresh supplies throughout the summer.
- Keep picking Runner Beans, French Beans and Courgettes. This will encourage them to keep cropping, and ensures that the veg is picked when it is sweet and tender.
- Grow a selection of lettuce varieties to give your garden or container an interesting range of colour and leaf shape – this also provides a mix of taste and texture for your salads. Don’t forget to use the lettuce seedling thinnings in salads.
- Do not allow containers to dry out. Many vegetables bolt (run to seed) or split if the water supply is erratic.
- For early beans start the container indoors and move outside once the danger of frost has passed.
- Protect your pots from slug attack with copper tape around the pot – they don’t tend to cross it!
- Plant some marigolds in with your tomato plants to discourage whitefly.
- Keep some polythene or fleece handy to cover young plants in bad weather. Always protect them from frost should the temperature fall significantly.
Tip! – Click the + and – icons below to reveal the answers.
- Bolting – this is where the plant grows too fast due to being either being too wet or too dry, resulting in the stem shooting up and the plant ‘going to seed’. To avoid this simply grow a ‘bolt resistant’ variety eg. Beetroot Boltardy.
- Chitting – encouraging your potatoes to sprout shoots before you plant them to give them the best start. Leave them in an open box on a light windowsill until the shoots are approx 2cm long.
- Pinching out – to encourage the growth of bushy side shoots you will need to pinch out the growing tip of the plant. This can be done with veg, flowers and herbs. NB. This process is not required for trailing or hanging basket tomatoes.
- Cultivar – a plant that has been specifically selected and bred for its characteristics and is not usually cross-pollinated.
- Crop rotation – the process of moving families of crops around your vegetable plot each year in order to avoid pests and diseases and to maintain good fertile soil.
- Grafting – the union of two growing stems from two different plants; usually a strong root stock with a tasty fruiting variety or an abundant flowering variety. This produces a super-strong plant that is disease resistant and provides a much bigger crop over a longer period.
- Going to seed – where a plant stops producing flowers and starts producing seeds.
- Hardy – a plant that has a high tolerance to the weather extremes (frost, drought) and can be planted directly outside.
- Half-hardy – a plant that needs to start growing indoors and can then planted out when the danger of frost is past.
- Annual – a plant that lives and flowers for one year only. These are ideal for sowing direct into the garden where you want them to flower.
- Perennial – a plant that lives for more than two years. Will generally be hardy so that it can survive the winter.
- Biennial – a plant that takes two years to reach fruiting or flowering.
- Hardening off – the process of acclimatising plants before planting them outside in the garden.
- Potting up/on – transferring your seedlings into larger pots so they have more room to continue growing.
- Hybrid – the cross-breeding of two plants chosen for their particular qualities (Eg. disease resistance, tasty fruit, greater yields), resulting in a new variety that has all the good traits of the parent plants.
- Jiffy 7 peat pellets – expandable peat pellets used for giving seeds the best start. No mess, just add water!
- Pricking out – once your seedlings have germinated they need a bit more room to grow so need to be transplanted into a larger seed tray or individual containers to encourage growth.
- Thinning out – the removal of overcrowded seedlings – usually from outside sowings. These surplus seedlings are usually discarded or in the case of salad crops such as lettuce, can be eaten!.
- Succession cropping – the process of sowing seed every few weeks to ensure regular cropping throughout a season Eg. Sow lettuce seed every two weeks for salad leaves throughout the summer.
- Tilth – the physical characteristics of the soil, Ie. a good tilth – a finely raked, crumbly structure with the right moisture content.
- Germination – the sprouting of a dormant seed following the provision of water, warmth and light.
- Drill – a shallow groove in the soil prepared for sowing seeds.
- Widger / Dibber – two tools that can be used to aid ‘pricking out’ and ‘potting on’. The Widger removes the seedling and the Dibber makes a hole in the compost for it to be placed into.
