Spring is here. Yay sorta... where I live and that means its mostly just winter temps and a lot of rain with a few nice days sprinkled here and there. This is not ideal for young seedlings... UNLESS... you do it in milk jugs. Yep Milk Jugs. Best part, you can even start plants in winter - yes outside.
Step 1
Rinse out your empty milk jug. Really any food grade clear or semi clear plastic container will work. Milk jugs are nice because they are wide and relatively easy to cut.
Step 2
Cut almost all the way around the jug about half way up - leave a hinge attached by the handle - about 2 inches.
Step 3
Poke drainage holes in the bottom. 4-5 should do it. You can poke 1-2 on the sides about a 1/2 - 1 inch up incase you get a ton of rain for extra drainage but I don't.
Step 4
Thoroughly wet your seed starting soil. Then fill the bottom half of your jug with your wet seed starting mix.
Step 5
Place your seeds. You can do more than you would think in a jug because you will be transplanting these out eventually.
Step 6
Label your jug inside and out.
Step 7
Tape (I recommend some form of water resistant tape - duct tape works well) the top back on the bottom creating a decent seal for your jug.
Step 8
Remove the milk cap - Yes rain and snow will get in there - that is ok. It also will provide ventilation for your seedlings.
Step 9
Place outside in a south facing semi sheltered location and let the magic happen.
Step 10
Once you have past your last frost date AND your seedlings have at least 2-3 true leaves, you can transplant your seedlings into the ground or pots outside. You won't have to harden off your seedlings because they are already used to the fluctuating temps and elements saving you the work of bringing them back and forth / in and out.
They are ready to thrive.
Things to consider:
- Check your seedlings about once a week for progress. (Lets be real you and I both know you are going to check them way more often than that LOL)
- These are really low maintenance. You usually don't have to re-water, but if there is no moisture on the sides, give your baby plants a drink.
- If the temps are pretty warm or it's really sunny you will want to un-tape the jugs to vent so the seedlings don't scorch.
- Some varieties can be started in winter. Anything that is relatively cold hardy will do great, especially if those seeds need stratification. (brassicas, onions seeds do really well, parsley, cilantro)
- Other varieties of heat loving plants would do better to start a little later (tomatoes, peppers and so on)
- You can usually get a good amount of milk jugs from coffee shops. If you call them in the morning and ask them to save you a bag of them, most will. You can get about 20+ jugs in a day this way for free. Make sure to rinse them out first.
- I recommend keeping a gardening journal to track what went well, what plants you tried and when you started them.
