Using a precise weeding hand tool like the Ergonica Weed Twister will
remove weedy eruptions without disturbing any more soil than necessary.
A conventional hoe blade, in contrast, is more likely to help the
germination of weed seeds that are exposed.

There are about 75 years worth of viable weed seed in any outdoor soil
that's been cultivated. A greenhouse will give you a different,
more heat tolerant selection of weeds compared to just the garden soil.
You might want to google the combination of the phrase "seed bank" with
the word weed.

Unless you're growing in sterilized soil, you're going to be weeding.
Clean mulch is your friend.
