Styrofoam egg cartons can be used as well; however, remove the plant from the styrofoam carton before transplanting because it does not break down in the soil. Seeds will germinate in just about anything as long as it holds soil and provides adequate drainage. Back to the egg shells.

Similarly, can I use egg cartons to start seeds?

Cardboard egg cartons can be used to start a dozen seedlings, and then cut apart to plant each one when it's time to plant them in the garden. As with newspaper seedling pots, there's no need to remove the plants from the pots before planting, as the cardboard will break down in the soil as the plant grows.

Egg cartons made of cardboard can be recycled just like other types of cardboard. Foam cartons, however, are not part of your curbside program. You can also put cardboard egg cartons in a compost pile. They break down quickly and will help create rich fertilizer for your garden.

How many seeds should I plant per hole?

Like most things in gardening, there are always exceptions to this rule of 2-3 seeds per hole. If you're planting large seeds like cucumbers, melons, or pumpkins, you should only use one seed per hole. However, you can still plant seeds close together and then thin them out once they've established themselves.

Are egg cartons compostable?

Yes, egg cartons can be used as compost ingredients if they are made of cardboard. Cardboard egg cartons would be considered brown compost matter (source of carbon). Make sure you cut the egg carton into smaller pieces before you dump it in the compost heap. Do not use the egg cartons made with foam or Styrofoam.

What do I do after my seeds sprout?

Fill the containers and pack the soil firmly to eliminate gaps. Remember that most mixes contain few, if any, nutrients, so you'll need to feed the seedlings with liquid fertilizer a few weeks after they germinate, and continue until you transplant them into the garden.

What is the difference between seed starter and potting soil?

Experienced gardeners generally have their favorites, while beginners may be at a loss as to what potting media to select. Although potting soils may be used to start seeds, they tend to have a more coarse texture and may contain field soil, compost or composted manure along with vermiculite, peat moss or perlite.

What seeds should be soaked before planting?

In the vegetable garden, this means peas, beans, corn, pumpkins and squash; even chard and beets. Smaller seeds — lettuce, radishes, carrots, and the like — are hard to handle once their soaked and don't really need it anyway. Flower seed to soak? Sunflower, lupine, sweet pea, nasturtium take well to soaking.

Is Styrofoam bad for plants?

The answer: Not really. In fact, if you are using a pot with little to no drainage, adding Styrofoam packing peanuts could do more harm than good. Deep plant roots can grow into the foam material, and without sufficient drainage, they can become waterlogged and rot or die.

Can I use Styrofoam instead of perlite?

Styrofoam as Perlite Substitute. Perlite is exellent for amending soil used for container grown plants and for starting seedlings in a soil or soiless medium. Blending for about 1-2 minutes and then draining in a sieve will give you a nice Perlite substitute. It has the consistency of coarse sand, but very lightweight.

Can you plant seeds in plastic cups?

How long does it take for seeds to germinate in soil?

At sowing time, mark the pots with the type of plant, date of sowing, and days to germination (found on the seed packet). Some seeds take two weeks or more to sprout. Poor germination can be caused by overly wet or cold soil, which causes seeds to rot.

Can you plant seeds in paper cups?

Starting the seeds and growing the plants in paper cups is economical, as well as gentler on the plant during transplant. Unlike transplants grown in seedling cells, those in paper cups can be planted still in their containers.

How do you germinate seeds?

To germinate seeds, start by filling a seed tray with a growing medium made specifically for seeds. Then, lightly press the seeds into the growing medium with your fingers and cover them with a thin layer of the medium. After you've sown the seeds, put them in a spot that's between 60 and 80 °F and lightly water them.

Why are egg cartons not recyclable?

Only clean, dry egg cartons can be put in recycling. If you place eggs back in the carton after cracking them, the carton is no longer recyclable: food residue is a contaminant for paper and plastic recycling.
