Seed Starting Guide: Quick Tips for Starting Seeds Successfully

Published by at 2:05 pm under Grow Your Own Food,How to Grow

As a parent, there’s no greater joy than sharing the journey of nurturing a baby from infancy into a healthy young adult. But I confess – I’ve been a bad ‘parent’ many times … until I learned how to raise my plant ‘babies’ successfully, they starved, drowned, died of thirst or neglect, too much love – or too little … So if you’ve struggled to raise seeds or are a beginner, then follow this tutorial on how to be a successful plant ‘parent’ and avoid these common mistakes.

Seed Starting Guide: Quick Tips for Starting Seeds Successfully

 

As a gardener, I’m practicing parenting skills almost daily raising plant babies.  And boy do I have a BIG family. Babies are being ‘born’ everywhere – in seed raisers, pots and garden beds. Some new additions are planned – and others not – but they’re all welcomed in my garden.

Over the years I’ve successfully raised thousands of seeds into healthy plants but it’s hard to keep an eye on these youngsters when they insist on entering the world unplanned in some spots in the garden! Being a plant ‘parent’, it’s much easier to raise these babies when you can control where they grow so you can keep a close eye on them and care for their needs.

 

Seed germination definition | The Micro Gardener

The miracle of seed germination: every seed contains everything it needs to grow its first 2 true leaves.

 

Every gardener knows that under the cloak of winter lies a miracle … a seed waiting to sprout, a bulb opening to the light, a bud straining to unfurl.  And the anticipation nurtures our dream.” – Barbara Winkler

Quick Tips to Raising Seeds Successfully

 

You have 3 options for sowing seeds:

  1. In a seed raiser for transplanting later when seedlings are strong enough.
  2. In a suitable container like a punnet for microgreens or other edibles in a larger planter e.g. poly box.
  3. Direct sow in a garden bed where you want them to grow permanently.

 

Pros and cons of starting seeds in containers

 

This video shows you two different methods of sowing seeds – in the ground & into seed trays.

What you can do with Out of Date Seed Packets

TIP: Check the use by date – just like us, seeds have a life expectancy!

 

  • Clean, hygienic, sterile container with suitable drainage. There are plenty of options for a ‘nursery’. You can buy new e.g. shallow seed raising flats; cell growing trays; biodegradable jiffy pots; a mini propagator and tubes; or make your own.

 

Repurpose plastic punnets as mini greenhouses to raise seeds - quick, cheap & easy!

Make seed raisers by repurposing items like plastic punnets, yoghurt tubs or biodegradable toilet rolls.

 

TIP: Use HOT soapy water to sterilise your container especially if reusing pots or seed trays so no soil borne diseases or plant pathogens contaminate your new seeds.

 

  • Growing media or soil-less seed raising mix (NOT commercial potting mix – it can be too coarse for little delicate roots to push through and often contains harsh fertilisers).

  • Cover (to create a humid environment) e.g. plastic bag, bottle, mini greenhouse etc.
  • Spray bottle or tray with water (no moisture = no germination).
  • Light – preferably natural light or a fluorescent light if raising seeds indoors (some seeds do need to germinate in darkness so this is a general rule that can be broken – check your seed packet for specific instructions!)
  • Label or plant marker (all babies need names and many plant families look very alike when young. I once transplanted out what I thought were cucumber seedlings into a raised bed, went on holidays and returned to find they were zucchinis that had taken up way too much space because I hadn’t labelled them.)
  • Patience!

 

Start at the Right Time

 

If you’re planning an impending birth, consider timing. Food crops germinate at specific times of the year depending on your climate zone.

 

Check your seed packet for the optimum time to plant so you don’t set yourself up for failure.

TIP: “If you have a short growing season, start early and select seed varieties that grow quickly!   Then you need to prepare a space that’s clean, warm, light and with the baby’s needs in mind. You can start seeds indoors, a greenhouse or suitable protected area.”

 

Like us, Seeds have Basic Needs!

 

  • Air (oxygen in the soil)
  • Moisture (to soften the coat of the seed and form roots)
  • Warmth (some seeds won’t grow if the soil is too hot or cold).

 

Seed Raising Mix

 

Start with a good quality seed raising mix – it should be lightweight with good drainage, moisture holding capacity and sterile, free from pathogens (soil borne diseases). You can buy a commercial mix or make your own. Garden soil is NOT recommended – it compacts easily and may harbour diseases.

7 Basic Steps to Starting Seeds

 

  1. Always check your seed packet for specific directions (e.g. to sow direct or into a seed raiser first, most suitable season, depth to sow, soil temperature, spacing, whether the seed needs light/darkness or pre-soaking).
  2. Spread your seed raising mix firmly into your container. Tap down to remove air pockets.
  3. Make sure your seeds have good contact with the soil as they need moisture to germinate. Small seeds or those that need light can just lie on top of the seed raising mix. As a general rule for larger seeds, sieve extra seed raising mix evenly over the seed to a depth of twice the seed diameter and moisten well.
  4. Put your seed container in a protected warm position such as on top of a hot water heater or use a heat mat underneath to increase the soil temperature. Keep your seeds in a humid environment until they germinate. e.g. add a cloche; close the lid on your mini greenhouse; or cover with a plastic bag or film. (Remove this once the seeds have sprouted).
  5. Make sure there’s consistent moisture once the seeds are in their ‘bed’ (too dry = no germination; too wet = seed can rot/die; just right = you’ll be the proud parent of new babies)! Check daily – Use a spray bottle to finely mist over the seeds or add your container/tray to a shallow water bath with warm water so moisture can wick up into the seed raising mix without disturbing your seeds. Remove your container when the mix feels moist. TIP: A moisture meter is a very helpful tool. 
  6. Label your seeds and be patient. Not all babies are born on time! Check the seed packet for a guideline to the number of days to germination so you have a ‘due date’.
  7. Feed your babies! Once the seed baby is ‘born’, it will quickly grow its first 2 true leaves. At this point your plant baby will have used up all the nutrients inside the seed and will be totally reliant on YOU for food to grow. A weekly liquid feed of a weak solution of seaweed (kelp) or worm juice (liquid from a worm farm) is ideal to get your little one thriving.

 

7 Seed Starting Tips for Successful Seed Raising

 

Successful Seedlings – Out in The Big Wide World…

 

If you’ve started seeds indoors, you will need to ‘harden them off’ for a week or two before transplanting outdoors so they acclimatize. Think of it like giving them short little day trips (for a few hours) to expose them to sheltered conditions to toughen up a bit without getting stressed!

From then on, your youngsters are very vulnerable until they grow strong enough to go out into the big wide world and fend for themselves. There are plenty of things that can go wrong – they can starve; get too hot, cold, drown or feel thirsty; get gobbled by hungry insects/animals looking for a free feast and a host of other hazards! So put your ‘protective parent hat’ on until they’re able to safely move house.

If you have sowed edible seeds directly in the garden, thin out and keep only the strongest plants. Eat the rest as microgreens, packed with enzymes and flavour.

Just like us, our plant babies need love and attention but if they get a healthy start early in life they generally grow into healthy productive plants that reward us for a job well done. So, get sowing!

    I appreciate the instructions on starting seeds as I have never been very successful at that part of gardening and usually go to the nursery and buy plants already to put in the garden. I only have a few raised beds and some earth boxes for gardening in, so my needs are small.

    I am going to print your instructions to keep in my gardening folder.

    Thanks
