How long until I can transplant?
bricksonsecond

I started my vegetables seeds in one of those inside green house things [plastic box with the biodegradable inserts for like 50 seeds] ... Do I have to wait until they sprout to plant them outside? If they have already sprouted and are hitting the top, should I move them?

First time at this. I bought a water trough to start a small raised garden. Hoping to get dirt either this week or next week, so just wondering. (of course it depends on where I live, which is MN and when frost shouldn't be an issue anymore.) My dad said I could probably transplant them and then cover the trough with plastic wrap to make a bigger green house type deal, just until they take off.

Tomatoes
Cauliflower (I heard you have to cover this so it doesn't brown)
brocolli
onions
peppers

Depending on your garden conditions, such as sun, temperature, soil, etc., the right time to transplant is when they reach the size of plants sold at your local garden department. Even then, expect some plants to fail.

When to transplant has more to do with soil and air temps (lows ), than anything else. If your starts are touching the lid of the starter box, just remove the lid and keep them indoors until planting time is right for your area.

If the plants are outgrowing their miniature peat pots, but it's still too cold plant outside, then transplant them into larger pots. Here's the thing, you do not want them to get root bound, because this actually stunts the growth and production of the plant. Planting them without disturbing their roots is the best, as it causes the least amount of shock and stress to the plant.

You can use cold frames/covers on plants over night, but you've got to be careful that you get them covered early enough to retain a little heat from the day, and get them uncovered in the morning before they suffocate in a hotbox.

If the trough is off the ground, or significantly raised above the ground and you get below freezing temps for some duration, like a couple of days, the soil could freeze so a cover would not do any good. You need to keep them inside until your temps are above freezing.

If your days are above freezing, you can put the plants outside with the cover off, but do this carefully. Only an hour the first day, then a little more each day. The sun, wind and cool temps will help keep the plants from becoming leggy. Leggy means too tall and thin.

If the medium you planted in are those peat pellets that swell up when you dd water, they are wrapped in a non biodegradable netting. I would remove that before transplanting. If you have peat pots, cut the pots apart before transplanting, they don't degrade as fast as you would like. They also tend to keep the inside soil, where the roots tend to ball up too dry and the plants can die.

The broccoli and cauliflower can withstand cooler temperatures, even a little frost so they can go out first.

Don't transplant before the seeds germinate.
