Indoor herbs

A week is not very long. Give them more time. Basil is easy, I have a few seeds in a pot they did take a couple of weeks to show their heads. Just keep the compost slightly damp. It could be that the seeds are old, you can buy some new on ebay. I did yesterday!

Soaking parsley seeds in warm water for a days helps them germinate.

There’s a saying that parsley has to go down to the devil three times before it germinates!

I don’t think it’s warm enough for coriander yet. I won’t sow mine till mid June.

Don’t know about basil.

Mint is always very hardy (damn stuff...)

Parsley is very slow to germinate, Basil & Coriander less so. Make sure they do not dry out, keep warm, be slightly less impatient & talk to them

They were exactly those herbs you say! Obviously something has gone wrong

I’ll get some more seeds/compost!

It all depends on what seeds were in the kit. But I suspect they may not sprout.
Basil, Parsley and Coriander are easily grown from seed. I wouldn’t use garden soil as it will possibly have weed seeds in it.

In the past I have bought the growing herbs such as chives, mint and Parsley from the supermarket and separated and re potted them in new compost. They then grow well. The pots they are sold in are only meant to last a week or so.
