Fast Food! DIY Instant Veggie Garden: Part 1

Do you want to make a quick mini garden? You can grow healthy ‘fast food’ like salad veggies and herbs in a simple box. Best of all, you can make it in about 15 minutes. The bonus is you’ll be eating the rewards in just a few weeks for only a minimal investment of time AND money. Let’s get started!

A wide variety of seasonal herbs, veggies and flowers can be grown in micro gardens and can reap you a rich bounty of food for minimum effort.


This is a system I’ve used for years with great success and it’s so easy. Even if you’re a beginner gardener or on a budget and need a thrifty solution, this is it!

I succession plant in new boxes regularly so I continually have a delicious variety of food crops to harvest for our table.


Materials you’ll need:

  • A table or workbench (I line mine with some newspaper to keep it clean while I’m putting my micro garden together).


Garden gloves on the table ready for potting up

You’ll need gloves, mask (for use with potting mix) and a trowel.


  • A new or undamaged, clean polystyrene box (Tip: I get mine free from local green grocers or supermarket, but you can try fish mongers or stores that sell fresh fruit and veggies – you’re doing them a favour by repurposing boxes that would otherwise end up in landfill).


Painted polystyrene box - use non-toxic paint or leave it white.

These come in a variety of sizes and depths and can be painted to suit your taste like I have here! This box is approx 45cm long x 20cm deep x 30cm wide.

The bottom of the box below:

Ready made drainage holes in the bottom of the box.

Choose a box that has holes already. Bean & corn boxes are fantastic choices (20cm deep) or broccoli if you want a 30cm deep one.


  • A suitable quantity of potting mix (I make my own – you can use my easy DIY recipe or a mix you are happy with but I suggest you include suitable soil food like I do so your plants are off to a healthy start).


Kids edible salad, herb & flower box

This is an easy project for kids too. Get them to paint their box in fun colours or designs.


  • Paper towel (about 4 sheets) or other suitable liner.


 An average watering can holds about 9 litres so mix up a strong solution of seaweed (kelp) according to the brand you use and add a dollop of molasses (available from produce or health stores).

Watering can with liquid or powdered seaweed and about 1 tablespoon of molasses to feed the soil microbes.


  • Selection of healthy seedlings (if you choose to grow climbers like peas or beans, you may also need a tepee or support stakes with ties).

  • A few handfuls of organic mulch.


Bag of sugar cane mulch - a sustainable by-product of the sugar cane industry.

I often use sugar cane or lucerne because these add vital nutrients and are chopped fine which makes them easy to handle. You can use grass clippings, chopped lemon grass or whatever you have handy to maintain moisture and regulate temperature.


  • Optional: Shade cloth or exclusion netting (depending on your situation and climate)!




Step 1: Wearing your gloves and mask, line the poly box with a couple of strips of paper towel to cover the drainage holes in the bottom and prevent the potting mix escaping.


Spray bottle with water.

Tip: I mist the paper towel with some water from a spray bottle to moisten before adding the soil mix.


Step 2: Tip in sufficient potting mix to sit about 1-2cm (1 in) below the lip of the box.

This is my light and fluffy home made potting mix. Tip: It will settle down after you water in so best to have it a little high.


Step 3: Using the handle of the trowel make a small hole for each seedling. (Tip: How close you plant depends on the variety – skinny chives can be planted ‘up close and personal’ but leave more room for veggies that like extra ‘personal space’ to mature.) See the spacing example below:

Garden in a Box after planting 4 x spinach seedlings at the back & 3 x capsicum seedlings at the front.


Below: Garden in a box a week later.

These seedlings took off because they were planted at the best time of the month using the Moon Calendar.

You can see the spacing is suitable as they start to grow. In the middle are 2 small bean seedlings which I transplanted after using this as a temporary nursery until I got another box ready.


Step 4: Pick up the pre-soaked* seedling and gently lower into the hole. (* See Tips below)


Be gentle when handling delicate seedlings. Hold by the leaves.

Tip: Pat down firmly so all the root hairs are in contact with the soil.


Step 5: Repeat until all seedlings are planted and then water in with seaweed/molasses solution.

Fast growing salad greens can be planted close for maximum use of space and then rotated with another crop when they are finished.


Step 6: Finally top with a few handfuls of mulch (about 2-3cm deep), leaving about 1-2cm (1 in) gap around the stem of each seedling.


Sugar cane mulch with a bamboo plant spacer and label.

A thick ‘doona’ of mulch protects tender seedlings – you can add a cloche if you need to or some shade cloth or netting.


Celebrate your new garden – add your plant labels!

Tips for a Successful Instant Veggie Garden:

  • Use a Moon Calendar to plant at the optimum time for an abundant, fast growing healthy crop.
  • Baby Love: Just like you wouldn’t throw a baby into a cot, you need to handle your ‘baby plants’ with care as they move from one ‘bed’ to another.


This is a healthy seedling with a well formed rootball ready to plant.

Hold the seedling by the leaves (the strongest part of the plant) to avoid damaging vulnerable roots.


  • Vertical Veggies: Want to grow climbing veggies like peas, beans, tomatoes or cucumber? Easy – add a tepee (get my free instructions on making yours from bamboo stakes for under $1) or portable A-frame trellis to your Instant Veggie Garden.

These snow peas grew really well up a four-legged bamboo tepee I made with one stake in each corner of the box.


  • Good Looking: Want to make it prettier? Get creative and give the box a coat of non-toxic eco-friendly paint or choose another container you like better.


Instant veggie garden in a box - use a variety of flavours, colour and texture!

Use your imagination to make a garden in a box as a gift for someone. I made this colourful one for my daughter. Complete with decorative shell mulch, garden art and a clay moisture meter worm!


  • Potting Mix: If you choose to buy a bag of organic potting mix, you’ll probably need around 15-20kg depending on the size of the box you use. Remember to add soil conditioners to feed the plants – I add these to my home made potting mix to save time when I want to start planting my garden.
  • Soak or spray your seedlings: To avoid transplant shock, sit your punnet of seedlings in a shallow container for about 15-30 minutes with a strong solution of seaweed (kelp) or add some to a recycled spray bottle and mist the seedling roots before planting (this takes longer though!)


Shallots, chives and salad greens - tall & skinny partnered with leafy veggies.

You’ll be amazed just how much you can grow in an Instant Veggie Box Garden. Have fun!

    Lovely post (as usual) and very informative. We are actually thinking about growing some veggies in containers like this to curb the possum problem that we have here at the moment. Anything young, tasty or vaguely palatable is being stripped bare and to avoid the sadness of discovering a garden bed full of only plant stumps where the day before there was a growing garden, and until we get our possum barriers built around our beds we could get some veggies happening in some polystyrene boxes. Great idea and cheers for the lovely pictures to accompany it.

    Hi Fran
    Thanks for your feedback and great to hear you’ll have some container veggies going soon. I’ve had to deal with possums when living in Brisbane – they used to walk along the timber fence making a bee line for the veggie patch night after night. I decided to work with nature and interrupt their visits by leaving them an alternative food source on the top of the fence before they made it to the patch. They seemed very satisfied with this arrangement so we both got a feed!
    There are pest repellant plants you might have growing that could also be useful to consider like chillis, lavender, quassia and eucalyptus. Penny Woodward’s brilliant book ‘Pest-Repellant Plants’ is a great read – maybe worth a trip to the library for details on how to use these and other plants in your patch.
    Hope this helps!

    What kind of paint do you use that’s safe.

  21. Anne Gibsonon 01 Jun 2014 at 7:45 am

    Chad, the safest paints that I’m aware of are labelled “no VOC” or “zero VOC” (volatile organic compounds), although I believe from the research I’ve done to date, that they still have a minimal amount of chemical compounds, rather than zero. You could look into a brand called Mythic Paint as a starting point. I haven’t used it myself but have read about it. You may also find it useful to read the comments section on this website on the following pages as there have been many similar questions and responses regarding paint:
