Planting seeds in January

WP_20140103_031

Though it is still pretty cold inside right now is the time for me to begin start planting seeds for this spring.  These include bok choy which are very cold tolerant, onions which do pretty good in the cold but could use a head start on these to get some good sized bulbs by the end of the season.  I also started some daisies which I will let mature plenty before bring them out.  Finally I planted some spinach to try to grow some greens for consumption in my grow box given how much empty space I have in here right now :)

For my seed starting mix I start with some coconut coir, though you can find this in the gardening section I typically grab a three pack at the pet store at nearly half the price.  Though looks like you can get it at a pretty good price on Amazon these days with free shipping.

All you have to do is add 1 gallon of water and let sit for a about 10 minutes then still a bit with a trowel.

Though this works great by itself as a seed starting medium I typically add a couple cups of vermiculite (to lighten up and moisture control) and a handful organic fertilizer to add some trace minerals to give the seedlings a head start when they emerge.

Finally will fill the Name Your Linkplant trays with your seedling mix and add you seeds, not watering should be required since the soil should already be pretty moist.

Complete by add some popsicle sticks with some handwritten labels or use a discarded yogurt container from your recycling container to make your own plant labels by simply cutting them into strips like shown below.

When to start garden seeds indoors: Seed starting calculator

When to start your vegetable seeds

When you start seeds indoors in a vegetable garden, it can be difficult getting your schedule down to ensure that start your vegetable seeds with enough lead time that they are mature enough to venture outside but also not so large they take over your growing area.

Personally this has been a difficult part for me where I am really good getting the early vegetables started on time (onions, peppers, tomatoes) but when it comes to the later plants and/or second/third plantings is where I begin to get forgetful.  Over the years I have come across a couple of great tools to make this easier that I thought I would share.

No matter which option you choose to start garden seeds indoors you will need to determine an important date, your last frost date. There are many sites/tables out there that will give an estimate I actually have a couple posts on the subject but at the moment my favorite site that makes this very easy is WeatherSpark, it uses historical data with great visuals to easily determine when the best probability of picking the right date. Here you can take a look at this historical data and make your call of what date you think will be safe.

1. Create a garden schedule.  Just by figuring out your last frost date and doing a little math (Excel works great for this) you can determine the optimal seed starting dates and even get a general idea of when your plants should be ready for transplanting.  What I love about this technique is you can tweak it each year as things worked well (or not so well) in previous years to get the schedule finely tuned to your particular garden and the micro-climates within it.

In addition knowing an estimate of when these plants will be venturing out in the wild can assist in your space planning for your seeding area as well as having a reality check if you see your peppers will be ready to be transplanted in March when it doesn’t get above freezing until mid-June.

Here is my schedule for starting seeds indoors my area and estimated last frost date (April 20th), though sure everyone that is reading this will not have the same date as mine so thanks to my infinite nerdiness I made the following table so you can adjust the “Last Frost Date” to yours and see how my schedule would look in your area.

* N/A because vegetables should be sown directly in the ground.

 

2. Create a garden plan online and get reminders.  My favorite online vegetable gardening software is GrowVeg.  It is very easy to use and provides some great visuals when to specifically plant seeds and transplant your seedlings outdoors, which you can see below.

In addition you also can recreate a virtual copy of your garden and plan exactly where you want to plant your vegetables, to ensure your ambitions for growing a huge crop this year does not exceed the reality of the limited space you have to actually grow.  It also remembers where you planted vegetables in previous years to help enforce crop rotation to ensure pests/diseases will be forced to remain in check.

Though one of my favorite features is the weekly reminders, once a week you get a simple email letting you know what plants you should be starting/transplanting that week.  This was very helpful later in the season where I probably would have completely forgotten about my carrots without this helpful reminder.

 

3. Buy a garden planning book.  If you want something that you can really get your hands on you might want to check out the Week-by-Week Vegetable Gardener’s Handbook helps with this problem by providing weekly reminders of what vegetables you should be order/planting and what preparations you should be doing in your garden.  This can be a very helpful tool in getting a little more organized in your vegetable garden.

Already falling behind on your seed planting here are a few great options to get a great selection of seeds without spending a lot of money:

  • One of my favorites is Burpee Seeds, they have been around since 1876 and definitely know their stuff. The actually have a seed sale going on now where you get $15 off on order of $75 (just use code AFFB4A35) expires on 1/15.
  • The name is not too exciting but Generic Seeds offers no thrills packaging with quality seeds and very reasonable prices and if you spend $20 or more shipping is on them.

Indoor gardening with 2 liter bottle and USB LED light

I came across this pretty cool Kickstarter from Vegetronix where they are putting together a neat little kit that includes an adjustable 1 watt that can plug into any USB port on your computer.  All you need to supply is an old 2 liter bottle and you have a nicely contained growing environment.

Personally, I think this could make an awesome addition to my windowless office and bring a little plant life to my personal space.

If the Vegetronix name sounds familiar, I use their moisture sensors in my grow box which I wrote here.
