Is there somewhere I can type in a plant name...

[Karbea]

And it'll tell me when to plant it?
I keep going to the garden centre or looking online and plants have just finished or aren't available till Nov...

I don't know of an app or a specific website but you could either search online for information about the plants you're interested in, or have a look at the RHS site for details/guidance?

I've got a load of herbs to plant up and now seems to be okay to do it. Most things sold in pots would be okay to plant up now, other things grown from seed may need to be sown later in the year, or next spring.

Yeah google!!!

Yeah I guess I need to just research stuff before I go and try and buy it :/

Don't forget you'll need to know roughly what type of soil you have, what aspect the area you're planting into has, and approx how sunny/shady it is.

Possibly easier to google the plants you're interested in and take it from there?

For advice about the care and cultivation of plants, the RHS website is excellent. Put the name of the plant you're considering into the search box at www.rhs.org.uk.

I use Shoot a lot, if you look at the details for each plant it tells you when it is going to flower, which is often the best guide as to when to plant it - ie just before the flowering season.

I guess garden centres usually stock plants that are currently in flower, because they catch the buyer's eye ; so they don't hold plants that have finished their display for the year; and online nurseries grow to order, to some extent, so they don't have limitless stocks of everything, and may have sold out for this year - hence not available again until November.

are you looking for shrubs, perennials, annuals?
