your listed planting dates for portland oregon are incorrect and misleading and will cause people who aren't familiar with gardening or the area to waste their seeds and kill seedlings. Sad !

https://garden.org/apps/calend...

The page says to transplant seedlings (Asparagus, Broccoli, Cauliflower, Asparagus, Brussel Sprouts, Cabbage) in the dead of winter, months before the last frost. The page also says to start squashes outdoors as early as 4/3 when the recommended time to start them in this region is 5/15. And recommend transplanting eggplants and peppers when it's months away from warming up or being hot out.

Hopefully you can edit the page to help prevent newbie gardeners from having bad data, failing and thinking it's their fault.

Here's a good reference for correcting the dates:
I wasn't allowed to link you, so replace DOT with . and it will get you there portlandnurseryDOTcom/docs/veggies/VeggieCalendarDOTpdf

Thanks!
Happy New Year and garden planning!

Welcome!
Thank you for joining NGA.

Please remember that the planting calendar is a guide...it is up to the individual gardener to make the decisions.

Looking at the USDA zone map, Portland has the same dates as where I live, Savannah, Georgia. Gardening in Portland should be very similar to gardening here.

Broccoli, cauliflower, Brussels sprouts, cabbage and their relatives can withstand low temperatures. I know because I am growing those where I live and they survived one of our rare winter storms with temperatures in the 20sF, low enough to freeze pipes - and the plants are fine.

The link you provided is 'a rough guideline' compiled by one nursery. If you ask 100 gardeners when is the best time to plant something, you will most likely get 101 different answers. Rolling on the floor laughing It is up to the individual to know their own mind and to know their individual climate and the microclimates in their garden. Also, many gardeners tend to push the zone by protecting early-planted crops with covers.

Please, take some time to look around the NGA site; check out all the features; get to know the lay of the land, so to speak. Join in on the conversations. You will find this to be a site with friendly folks who enjoy sharing information about plants and gardening.

Out of curiosity, I looked up a town not far from me in the calendar. I was pleased to find that:

"You appear to be in an environment where frosts aren't an issue for you, so we can't properly advise you on planting dates. For advice on gardening in the frost-free areas of the world, we would advise to peruse our veggie-related discussion forum."

Right now the temperature is 12F (-11C) and it's snowing. Hilarious!

@sooby
For @dave to check into this it would help if you provide the name of the town you looked up and maybe do a screenshot of the page. Thumbs up

Portland : Howdy 😀 !
Best advice, ask a local farmer. 👍
Ag extension, nursery, see Sunset Western Gardeners Book, Old Farmer's Almanac, or ask neighbor who gardens.

@greene Savannah Georgia may technically be in zone 8, like Portland, but this does not mean recommended planting dates should be identical.

USDA zones merely indicate the lowest possible temperatures a place gets. Savannah is about one thousand miles closer to the equator than Portland Oregon.

i understand that March and April in Savannah rarely get below 43, but in Portland we actually get frosts till early April, often. Our summers are A LOT cooler here, and don't warm up to hot till June, sometimes July.

If you transplanted the plants suggested during the dates that webpage recommends they most likely would not survive without a cold frame, even if the weather was mild and they didn't freeze and die you would not get enough heat to get successful vegetables without a cold frame.

USDA zones do not dictate planting dates, and if this website thinks so and bothers to make individual city-specific web pages dedicated to that nonsense, that's crazy!

This website perpetuates bad information, but I am willing to personally update Portland's webpage with correct dates.

But also, why not just have one page with a zone map and a chart for each zone, at least that way it's clear how general these recommendations are instead of leading people to believe they are looking at city specific information... Or better yet don't even offer planting dates at all if they are based on irrelevant data.

Thanks

Any of this type of chart is merely a guideline.

Yes, as you point out so emphatically, Savannah is different than where you live. Heck, even a portion of my yard is different than the rest of my yard.

That is why we should use the information offered only as a starting point; it is up to each individual gardener to know his/her own mind and own yard/property. Also why so many of us use protective covers and structures when planting either early or late in the season.

You have made your point and we will have to agree to disagree. Thanks.
Hope you enjoy NGA. Thumbs up

@greene I'm not sure exactly what we are agreeing to disagree about... Can you clarify for me?

Thank you
