#14: Best Tips for Planning Your Fall Garden
If you live in a mild winter climate your garden should not end with summer. You have the opportunity of growing a fall garden that thrives throughout the fall and winter months and continues producing until late winter or early spring.

Best Tips for Planning Your Fall Garden
Many gardeners in colder climates are limited to planting cool-season crops in late winter or early spring because their fall season isn’t long enough for crops to mature before heavy frost or snow sets in.
However, if you try to follow that same planting timeline here in Zone 9, you’re likely to encounter some significant challenges.
Planting cool-season crops in early spring might work for some, but the majority will bolt and head to seed because they won’t have enough cool days to mature before the weather gets too warm. This is a common struggle I hear about all the time.
Gardeners often feel defeated when their cool-season veggies fail, but it’s not usually their fault—it’s simply a matter of planting at the wrong time.
Have you ever experienced your cool-season crops bolting and going to seed before you got a harvest? I know I have. But the good news is, with the right timing, you can enjoy a successful fall garden.
In today’s post, I’m sharing tips on how to time your fall planting, the key differences between cool and warm-season crops, and why fall is my favorite gardening season of the year!
Timing is Everything
One of the biggest mistakes gardeners make is assuming there’s a set planting date for each crop. The truth is, planting dates vary depending on your specific climate, and they can even vary year to year in the same location.
You can’t rely solely on a calendar date—you need to consider the ideal growing conditions for each crop and plan accordingly. Let me help you figure that out with a quick example.
Let’s say you want to grow Brussels sprouts. These are long-season crops that take 90-120 days to mature and thrive in cool weather with temperatures ranging from 50-70°F.
Brussels sprouts are hardy and can withstand temperatures as low as 25-28°F, but they’ll stop growing and go to seed if the weather stays consistently above 70°F. So, for 3-4 months, the weather needs to remain consistently cool for the plants to mature properly.
In Zone 9, it’s not uncommon for February to warm up with consecutive days in the high 70s or above. To ensure a successful crop, you should plant Brussels sprouts in September or early October so they have a long enough cool season to mature.
On the other hand, shorter-season crops like radishes mature quickly, in as little as 25-30 days. These crops can be planted throughout fall, winter, and even early spring if cool temperatures persist because they mature so quickly.
However, if you plant Brussels sprouts in January, it’s unlikely they’ll have 90-120 days of ideal growing conditions, making it difficult for them to mature.

Planning Your Planting Dates
To plan your fall garden, you need to know the season length of each crop, whether it’s a short, half, or long-season crop. This will help you determine how long it will take to harvest from the time of planting.
- Long-season crops (90-120 days) should always be planted in the fall for success. Examples include Brussels sprouts, garlic, and leeks.
- Half-season crops (50-80 days) are best planted in the fall but can also be attempted in late winter or early spring. However, in warm spring climates, these crops may bolt and go to seed before reaching maturity. Examples include broccoli, cauliflower, and kale.
- Short-season crops (25-60 days) are the quickest to mature and are great for planting throughout fall, winter, and early spring. Examples include radishes, lettuce, and turnips.
If you’ve struggled with cool-season crops in the past, I hope this clears up some confusion. One of my pet peeves is when I search for gardening information online, and it simply gives a planting date without considering important factors like climate, winter severity, season length, and ideal growing conditions.
Now that you know what information you need to plan your cool-season crops, it’s time to start planning what you want to grow.
Even though it’s still summer, you should order your seeds soon so they arrive in time for planting.
