This is what makes it all happen; the start of every good garden, the results of wintry months perusing seed catalogs,your selection have finally arrived in the mail~ Hooray! Time to plant!
There are a few things to consider; first and foremost timing. To insure that you have good healthy plants ready to set out into the garden at the appropriate date, rather then those that have been in their peat pots too long and gotten lanky and weak trying to reach for the limited sunlight available indoors. Leaving seedlings in their starter pots will leave them weak and unlikely to thrive, it is so important to give them every advantage when you do start seed indoors so that your investment will pay off too!
First, Check your dates; each individual packet will give estimated days to germination and recommendations for weeks until they are ready for planting outside.
For instance the Celery packet notes that direct planting is
Not Recommended, therefore growing unusual strains such as this "Redventure Celery" starting seed indoors is your only option.
Celery takes from 10 -20 days just to germinate, that is 2-3 weeks! (Granted I am a bit early, they suggest starting seed in February, but I have a plan which I will share with you later. :)
However, taking these time frames into consideration are very important to your success when planting out into the garden. Referencing again the Celery it is recommended that it not be planted out into the garden until soil temperatures reach 65 degrees, which we know here is Portland won't arrive until mid to late May or early June!
It follows then that potting up into larger containers over the coming weeks will be required, but to experience this delicious and rare vegetable it's worth the effort!
The great news is that it is not only simple but also fairly inexpensive! Costing only about $25 for a windowsill sized heating pad, for warming the soil to encourage germination, the 36 unit starter tray with water reservoir and 'green house' cover and enough potting soil to last you for many seasons to come.
Beside which, it takes only a few square inches of area within your home, approximately 6"x 21" and access to electricity is all that is required!
It is also important to use a potting mix which is made specifically for seed starting. One which is exceptionally light weight but contains no nutrients. This implies you have to been ready to move them into a larger temporary pot when the time comes, but we will cover that in a later post!
Here is what is required:
#1 The Heat Pad to assure warm soil temps around, 55-70 degrees are required for most seeds (this will be noted on the seed packet too!)
I have a small home so I selected this window sill size, but there are a variety of larger units available to suit larger spaces.
#2 The planting tray, soil & a small trowel.
Next you simply set about filling the individual cells of the starter tray with dry potting soil, we will add water after the seeds are planted!
This tray holds 36 cells or 4 "Six Packs" like we are accustomed to buying at the garden centers.
Once the cells are filled to the brim, but before adding seed, use one of the neighboring six packs to tamp down the loose soil, as shown below,to prepare a firm bed for the seeds which we will add next!

A light touch is all that is required to firm the soil;
Now for our seeds; I am choosing to use just three type of seed as I want to start one dozen Kale plants but only six each of the Broccoli and Celery.
Seeds are very unique, you may enjoy learning to distinguish them, cruciferious vegetables all seem to have similar circular pellet like shape, here is a close up view of the Kale seed;
Which is much larger then the celery seed;
Starting vegetables from seed, if it is organic non hybridized seed, will also allow you to save seed from these plants at the end of the growing season to collect for use in your next year's crop, which is the ultimate goal for the sustainable urban homestead gardener.
With the cells filled and tamped into cozy beds ready to receive the seed, prepare to sprinkle only two or three tiny seeds into each cell of the cells of the four six packs.
With the Kale seed it is much easier to select just two seeds where as with the itsy bitsy celery seeds you may use more then intended and need to thin your seedlings later on when they are well up.
We will cover that at a later date in a separate blog post.
For now, we just want to get the seeds into their individual cells, cover them lightly with another dusting of potting soil and again tamp them down to secure the seed into the soil using the neighboring six packs.
If you run across any larger chunks within the planting mix, simply remove and discard them, we don't want the little seedlings to have to do any weight lifting in their first few days of life!
Now that we have all those seeds tucked away into their little beds all snugly tamped into place, it is time to give them a drink! But Never Ever water freshly planted seed trays from above, that is the job of the water reservoir!
As seen below, place the planted tray over the heat pad in it's (semi) permanent location, near a sunny window, this window is north facing where my orchids enjoy the indirect sunlight, it never gets too hot but offers an adequate number of hours of sunlight per day.
Finally it is time to cover those little babies up and keep them warm! Placing the 'green house' plastic cover over the top once you have filled the water reservoir with retain all the warmth and become the nurturing womb the seeds will thrive in and grow!
Before we walk away, let's do a spot of Math, shall we?
Remember the info on the seed packets? One of those important items is the 'days to germination'. Making a small note on a bit of painters tape showing the estimated dates seedlings should appear will keep you on track! As I'd mentioned earlier, Celery takes from 10-20 days whereas Broccoli and Kale is only 5 - 10 days. Since these were planted on January 15th, 2011 I anticipate the celery sprouts between the 25th of January and the 5th of February as I have noted below.
Simply post the notes on the side of your tray as a simple reminder of when to hand out the cigars & balloons as celebration of your little darlings arrival!
We are not quite done here however, there is still a spot of clean up and storing to do!
As you probably noted we have used very little seed here! Another nice aspect of indoor starting is there is less seed waste and as these packets run as much as $2-$6 each depending upon the variety, rarity and limited quantity available we want to ensure that none goes to waste!
So I offer these simple tips to make sure that when these trays are free a few weeks from now you will still have plenty of viable, fresh seed to start the second crop thereby insuring you have continual supply of fresh quantities throughout the growing season!
Tip #1. Seal them in plastic zip lock bags to keep them dry!
Tip # 2 Choose a waterproof container


Finally, store them in an area out of the way of any direct sunlight or heat source but handy enough to have them easily available for the next planting session!
Now go on, pick up that seed catalog or garden magazine and dream a little. Planting out into the garden is only a few weeks off, again, the seed packets will give you a good indication of how many days from sprouting the seedlings will be ready to be set out into the garden, based upon soil temperature most often. Some potting up to larger pots and 'hardening off' may be required; that is simply leaving them out during the day uncovered when the air temperatures rise at least to the mid 50's. My best guess is mid April to early May believe or not that is only 12-15 weeks away!
Those dozen weeks will fly by and in the mean time you will have dozens of beautiful organic healthy seedlings to keep your thumbs green and your gardening dreams flowing!
So go on give it a try and happy gardening!
