They will bloom in succession, but you can plant snaps from groups 1,2,3, and 4 to stagger bloom times!  Group 1 and 2 bloom first and are better grown under shorter days and cooler temperatures (winter and shoulder seasons). Groups 3 and 4 are meant to be grown during the warmest months.

Don't forget about watering throughout the winter, and air circulation is important in all seasons! Let the plants breathe by opening the doors/sides on warmer days

In zone 6, you can plant Snapdragons in the fall, but they will need some protection (frost cloth, low tunnels) over the winter for best results. Stock would be best planted in the spring.

It can be difficult to time out a crop perfectly when there are so many variables that affect the speed of growth. Stocks have a fairly short window for harvest across the crop, so you should likely plant a couple of successions in hopes that one of them hits your goal date.

N:P:K is nitrogen, phosphorus, and potassium. Nitrogen promotes lush green vegetative growth, so choose a fertilizer with a low 1st number.

With protection, yes. They would need to be in a high tunnel, or a low tunnel with additional protection from frost cloth or Agribon during the coldest periods. I wouldn't personally plant them unprotected in the field in any zone colder than 7, but fall planting always comes with risk.

One big thing to keep in mind with Digitalis is that well-draining soil in the winter is vital. You can be in zone 5 with well-draining soil and your digitalis will overwinter better than someone in zone 7 with soggy soil.

It's really just as necessary - if you have sandy, well-draining soil you will need to water more frequently compared to someone with clay soil. Check often. Oversaturated soil will kill your plants faster than the cold; it's important that the soil drains and isn't soggy.

Shade cloth and keep them irrigated is your best bet. They won't be happy off the bat, but crossing my fingers they establish for you in the heat! Try an earlier delivery next year, they can handle being planted before your last frost date, and prefer that cool establishment period

You might want to consider a broad-spectrum fungicide once they establish because Bells are prone to foliar diseases in heat and humidity, bacterial leaf spot, and the like. Keep an eye out for it on the lower leaves.

Yes, leave foliage through the summer. Just keep it cut back/deadheaded. It shouldn't die back fully

Rodents are definitely tricky in a tunnel! Rabbits and voles are both prevalent. Maybe others can chime in on what works for them. I'm not the best with mammal pests. Don't keep your landscape fabric down in the winter

Via flower farmer Betsy Hany:  I use organic spray - Liquid Fence. It STINKS. But it WORKS. Someone else may say “get a cat.” I will not be that someone, but I’ve heard it works!

Colibris really do best fall planted because they struggle so hard when the heat hits. Mine always gets hit with thrips. I find Champagne Bubbles a little more easygoing but the flowers are a little less spectacular. The Colibris were bred for more temperate zones, so I feel like they do better in those mild areas.

It should overwinter OK in zone 6 and warmer, maybe colder zones if in a hoop. It was bred in the Netherlands and hasn't been extensively trialed in colder areas, but it's a barbatus type, which are generally very hardy.

Theoretically, that timing should work - don't be shy with irrigation and fertilizer, as this also really helps Lisianthus grow well and reach their full potential. It wouldn't hurt to plant them earlier, more like October.

This is great! You can grow almost any cool-season crop over the winter if you have a heater and you're keeping the temperature above 0F overnight. Some things won't grow much because the day length will be too short to support active vegetative growth, but they will take off as soon as day length gets long enough.

If you want an early bloom, grow groups 1 and 2! Chantilly is a favourite if you like open-faced snaps. We have a few varieties in those groups on our website.

2 or 3 per square according to the Growing Guide https://farmerbailey.com/pages/stock

Our plugs often come multi-seeded and grow well if left with 2 plants per plug.

That falls mid-September, you should likely be planting plugs then, depending on where you are and how early your first hard frost is. You could direct sow Larkspur seeds then as well, they are hardy as little seedlings over the winter.

Not at this time, but we can add to the wish list! Add your wishlist crops here:

Via flower farmer Betsy Hany: The big-time English growers of delphinium recommend thinning out the number of stems you allow to grow up and bloom. I tried this with half my crop of Astolat this year. It worked! The stems on the plants I thinned were wicked thick, while the others were quite a bit thinner. I kind of like both for some design purposes and will be continuing this method of 50/50 moving forward.

You should theoretically be able to! I would suggest planting them early enough to establish a bit before the cold hits. Mine overwinters and spreads (reseeds) no problem here in the open field in zone 5.

I wouldn't suggest pinching Campanula.

Zone 5 and 6 with protection. You might be able to get away in zone 6 in the open field, but it's a gamble! Depends on the severity of your winter weather. Zone 7, unprotected, you should be OK.

Via flower farmer Sarah Schneider: Zone 5 with protection.

They are true biennials and will likely die after flowering. They are pretty new on the market and have not been extensively trialed in the US, so this is just educated speculation.

While the weather is warm/cool, they don't need to be sealed up under cover. Plants prefer good air movement and ventilation, so I would only cover them with plastic when the temperature forces you to.

Yes, our growers have large professional germination chambers that keep the temperature and humidity at the perfect level.

Absolutely, you will get smaller side shoots. The first/main cut is typically the largest.

Likely a minimally heated tunnel to keep the temperature above 0F at night. Anemones from seed need a longer period of cool weather compared to Anemones from tubers. They need to be planted earlier and take a little longer to get to blooming size.

Campanula, Hummingbird Poppies, Pansies, Delphinium (not truly and annual, but often grown as an annual), Stock (for the incredible fragrance.) 

All of the annual plants can be planted in pots and dragged into the garage for very cold spells. 18" pot, 3-5 Campanula plugs. Pinch for multiple stems. Easy way to have a giant impact. Putting a few showy annuals in a pot is a great way to celebrate spring, show off a bit… Put something showy in a fancy pot, fill it with flowers.

We see people in that region planting around Thanksgiving, can push it later than other people. Crop dependent, but after Thanksgiving is safe for nearly everything. 

You may be getting too much heat or hot intervals. Get them in the ground and feed a lot right away, grow as fast as you can.  Plant around Thanksgivng as days shorten and temps cool. 

Don't know for sure.  Geum will overwinter. I've had it for 2 years, but it’s not flowering well for me; you may want a bit of chill. Tweedia is hardier than we give it credit for, zone 8 perhaps.

I wouldn't risk it! They have been developed in the Netherlands, which is more like zone 8/9. haven't been extensively trialled in colder US zones. I would still plant them, just give them cover.
