How to Make your Own Vegetable Seed Starting Soil

If you want to ensure that the vegetables you grow are the healthiest they can be, then you must be involved in the growth of your vegetables from the start and that means growing them directly from vegetable seeds as opposed to buying established vegetable plants.

Now that is not to say that the vegetable plants you buy from your local garden nursery or home center are bad. It simply means when you start your vegetable plants at home from vegetable seeds you are in complete control of the environment in which your vegetable seeds will germinate and where they will grow.

This is important, because when you start directly from vegetable seeds, you get to choose the vegetable seed starting soil. The better the vegetable seed starting soil, the better the start will be for your vegetable plants, and in turn the healthier they can become.

Just like a tall skyscraper needs an excellent foundation, so do your vegetable plants. This foundation is your vegetable seed starting soil. The best vegetable seed starting soil you can have is one that actually contains no soil at all. Instead your vegetable seed starting soil is made up of three different ingredients.

Whether you make your own vegetable seed starting soil or buy commercially packaged vegetable seed starting soil, all should have these three main ingredients. Each of these three ingredients serves a purpose that helps your vegetable seeds germinate.

What you should be looking for in your vegetable seed starting soil is an ingredient that helps with water absorption so that you do not over water. That usually comes in the form of perlite or vermiculite. Both readily available at any garden center in its own form and will also be included in many commercial vegetable seed starting soils.

The second ingredient that should be on your radar is something that will make your vegetable seed starting soil loose and friable. Two good choices are sphagnum moss aka peat, or coir, which is the fiber extracted from the husks of coconuts. Both can be found at local home and garden centers or online.

Finally, your vegetable seed starting soil must contain some form of fertilizer otherwise the vegetable seed will not get the nutrients needed for proper germination. There are a wide variety of choices and combinations here, but the simplest vegetable seed starting fertilizer you will find is compost. Easily made at home, you can add in your own compost to your vegetable seed starting soil, which gives you a true, self made vegetable seed starting soil.

So how do you make your own vegetable seed starting soil with the items mentioned above? Making your own vegetable seed starting soil is very simple. Combine equal parts of all three ingredients, that is one part perlite or vermiculite, one part peat or coir, and one part compost, then mix them together.

Your homemade vegetable seed starting soil has everything your vegetable seeds need to germinate properly.

As mentioned earlier, you can also purchase vegetable seed starting soil from your local home or garden center. There a variety of different combinations of ingredients that are used with commercial vegetable seed starting soils, so be sure to read the packaging to know exactly what you are buying. Some are formulated for specific vegetable varieties, such as tomato or pepper mixes, make sure you read the bag before you buy.

Seed Starting with Homemade Starter Pots

Your vegetable seeds come in all shapes and size.  Just as many sizes and shapes your vegetables come in is as many ways and methods to germinate your vegetable seeds.  One way to start your vegetable seeds that I addressed in a previous vegetable seed starting video is to use vegetable seed starting peat pellets.  These are expandable pods that you add hot water to and they expand so you can plant your vegetable seeds in them.  Here is a link to that vegetable seed starting video.

The vegetable seed starting (creative) pots I wanted to talk about today, were a couple of things I have done myself with good success.  The best part of these two vegetable seed starting pot options is that they are made from a couple of household items that you already have in your home.

Of course, as we all know, regardless of what you use as a vegetable seed starting pot, your vegetable seeds do not stand much of a chance, if you do not give your vegetable seeds a great seed starting soil.  You can either buy vegetable seed starting soil, or make your own vegetable seed starting soil with a mix of compost, peat and perlite in equal parts.

Now that you have your vegetable seed starting soil, let’s begin with talking about our first home made vegetable seed starting pot, and that is using empty cardboard toilet paper rolls.  Cardboard toilet paper rolls are great to use.  Cardboard toilet paper rolls are biodegradable, which makes them perfect for starting your vegetable seeds in because as the seeds germinate and the plants grow, the roots will want to expand.  If the cardboard toilet paper roll did not break down, the roots would have nowhere to grow. 

The water and the environment will break down the cardboard toilet paper roll for you, so you do not have to worry about it.  Here is an excellent step by step guide for turning your cardboard toilet paper rolls into vegetable seed starters: http://www.yougrowgirl.com/2007/04/13/toilet-roll-seed-starter/

I don’t believe in reinventing the wheel, and in this case, retelling the same vegetable seed starter story, so I had to link to it since YouGrowGirl.com does a nice job explaining the process of turning your cardboard toilet paper rolls into vegetable seed starters.

The second crafty vegetable seed starting pot you can use is turning in those cardboard egg cartons into vegetable seed starters.  Cardboard egg cartons work great because they are plentiful, making vegetable seed planting and space saving a great combination, and just like with the cardboard toilet paper roll, they will breakdown when you plant them into your garden.

“Growing up Creative” has a wonderful step by step tutorial showing you that it is so easy to start your vegetable seeds in a cardboard egg carton that even a small child can do it!  This is true as I have seen my own 5 year old son use an egg carton to start some vegetable seeds.  Here is a link to the vegetable seed starter with cardboard egg carton tutorial: http://www.growingupcreative.com/2010/03/howto-egg-carton-seed-starter.html

Sure neither of these homemade vegetable seed starting pots is earth shattering news, but if you are looking for some projects to do with the kids, or needed a good use for all of those cardboard ‘extras”, these are two more ideas in your arsenal.

Grow Carrots from Seeds

Every time I cut up a carrot, especially the carrots that I harvest from my home vegetable garden and have grown directly from carrot seeds, brings back memories of my childhood when my grandmother would pull some carrots from her home vegetable garden and use them in her homemade chicken noodle soup.

I remember the image vividly of those long bright orange carrots coming out of the dark rich soil in her home vegetable garden directly behind her Trenton, NJ house.  I remember her cutting those carrots up with a knife, using such precision that the sight of the evenly cut carrot slices would make an electric powered carrot slicer or food processor jealous.

She would then add the carrot slices to her homemade chicken soup broth to soften, and then finish the recipe.  While I have never been able to duplicate her chicken noodle soup recipe, no matter how hard I have tried, duplicating the process of growing carrots from seeds at home in my own vegetable garden has become almost second nature to me these days. 

Growing carrots from seeds, while challenging, is not impossible.  A couple of challenges you will find when growing carrots from seeds in your own home vegetable garden, include, the size of the carrot seed, spacing those seeds out, and, making sure the soil you are growing your carrots in is friable.   That is … the soil for your carrots should be very loose or able to crumble into small pieces.

Let’s first talk about the size of your carrot seeds.  Carrot seeds are very small.  Not as small as celery seeds (celery is another ingredient in grand mom’s chicken noodle soup), but hard to handle on an individual basis nonetheless.  If you plant carrot seeds too close to one another, the growth of your carrots will be inhibited and then you will end up with either small and fat carrots or your carrots will not grow at all.

A good friend of mine online, Gardening Jones, writes a wonderful blog.  On her vegetable gardening blog, she writes a step by step process on how to make your own seed tape and she uses carrot seeds for her example.  I have linked to that blog post here: http://gardeningjones.com/blog/2012/05/01/planting-seeds-made-easier/

A seed tape is nothing more than as out it sounds.  You take your carrot seeds, place them on a long piece of tape, usually a masking tape variety, spacing your carrot seeds out as per the instructions on your carrot seed packet, and then plant the tape (with the carrot seeds on it of course) at the depth that is written on your carrot seed packet.  Moisture and weather conditions will remove the carrot seed tape’s adhesive.  This allows your carrot seeds to be planted as normal except your carrot seeds are nicely and evenly spaced out for optimal growth.

As for the carrot seed tape, or in the case of Gardening Jones’ carrot seed tape tutorial, tissue paper, that will simply erode away and become compost in your soil.  So you do not need to worry about taking the carrot seed tape out once planted.

For the soil your carrots will grow in, it needs to be loose, friable and crumbly.  If you have soil that is heavy in clay, the quickest way to accomplish what your carrots need is to add plenty of perlite, compost and peat.  This will loosen your soil up for your carrots, very quickly.    While perlite and peat are available at any home center, you will more than likely need to make your own compost.  These ingredients also add other useful things to your soil for your carrots; however I will save soil enrichment for another time.

Proper spacing and loose soil will ensure that when you grow your carrots from seed, great results will happen, every growing season.
