I would wait until Spring, because even though they are hardy, they are after all still seedlings. I used to grow ours in pots, but read that they do much better in the ground. Pots tend to dry out easily in Summer, and Dierama prefer soil which is moist (but well drained). They are also clump forming, but don't like being moved, so if you do put them in pots, you'll be faced with what to do when they clump up to fill the pot. In my experience, that means forcing them out of the pot so you can re-pot them, and therefore no flowers for several years.
So essentially, plant in in the ground in Spring. Find a spot where you ideally won't need to move them for years, in full Sun, with moist but well drained soil. And enjoy.

Makes sense. Just itching to get out and do something. I’m sure most on the forum feel the same.

We are in the South East and have an unheated greenhouse. Is it too early to sow Cornflower, Cosmos, Marigiolds and Lychnis coronaria?

My greenhouse is unheated. I keep watering to a minimum in Winter and wrap up the non-hardy pots in bubble wrap. This saves lining the whole greenhouse and we haven’t lost anything yet.

My favourites are Psilostemon and Susie White, for sun, and Svelte Lilac for shade. I got them from Plantsmans Preference. They have one of the best collections of hardy geraniums in the UK.

Nothing outdoors, but flowering in our unheated greenhouse, Freesia laxa Azurea

Not forgetting Symphyotrichum, formerly hard to pronounce Aster. Rolls off the tongue, eh?

You know when you already know the answer to something, but you just need that little bit of reassurance?

For the past few years, I've put my potted Dahlia's and Calla Lilly's in the greenhouse, still in their pots/soil. This has worked well, but advice is always to store in a cool/dry place, and although the green house is dry and unheated, it can frequently get warm on sunny, Winter days. Would it be better if I put the pots in the shed?

Depends on which grasses they are. For example, I have Stipa Gigantea in pots. You don't cut them back, but just pull out any older, dead foliage, same with Festuca Glauca for example. Miscanthus I do cut back in early Spring. Which grasses are they?

Good luck if you get any nuts. Tufty the Squirrel enjoys all of ours.

Should have added, it is hardy, but short lived. I always grow one or two extra each year.

It’s Black Knight. A beauty.

Should Oxalis adenophylla bulbs be showing above ground or should I plant them deeper for Winter. I lost one last year, possibly due to poor drainage.

Good point about soil leeching. I’ll leave it as it is until late winter.

Is my green manure ready to dig in or do I leave that until next Spring?

I lost an Oxalis adenophylla last year. Planted another one but the bulbs have pushed themselves above ground. Should I leave them like this over winter? I know they like good drainage and so was wary of mulching them.

Our green manure is doimg well. Do we dig in now or leave it until spring?

Thanks. They are very healthy so I'll part cut back and put some bonemeal and garden compost in the planting hole.

We are moving Peonies. Should we cut back the foliage?
