When to plant brassicas [Detailed Guide]

When is the best time to plant our brassicas? Well, for many of us, there are two ideal times to harvest our kale, Broccoli, and Cauliflowers; spring and fall. You see, Brassica crops simply taste better when you avoid harvesting them in the heat of the summer. So by knowing how long these guys take to grow, and when we want to harvest, we can work backward and find the exact dates we need to be starting our seeds!

Brassica oleracea, this genus of plants commonly called cabbages is an absolute staple in temperate gardens and they’re super easy to grow provided you get one thing right.

When do we plant brassicas?

When do we plant brassicas?

Cabbages and their cohorts taste best when they’re harvested in cooler weather. But that doesn’t mean that’s when you plant them.

Some leafy varieties are tolerant of really cool weather, such as kale and collards. But for the most part harvesting just above freezing is ideal. This is why timing is so important to brassicas.

In temperate regions, we have two ideal times to harvest – spring and fall.

Fall is easiest to grow for because we have the warm weather to enjoy to get these guys started. But as brassicas are almost never direct seeded a spring harvest is entirely possible as well.

From the time of sprouting most brassicas, even the large fruiting kinds are a 50-70 day crop.

At 75 to 85 degrees Fahrenheit germination takes roughly 5 to 10 days. So now we have a known window of growing time, great.

So for a fall harvest start your seeds roughly 60 days or two months before your first fall frost and for a spring harvest start your seeds indoors about a month before your last spring frost date.

These dates will time a cool harvest perfectly and avoid freezing or damaging weather.

For warm climates, you can be a little more fluid. The easiest is to start your seeds in the hottest month of the year. So if you’re in southern California start your seeds in august to enjoy that November harvest.

Thanks for reading guys.
