We will be CLOSED Monday, June 8.

Why?

Because after working 7 days a week since November, Mallory has officially decided she needs a day off. Her plans are simple: get a pedicure and take a mid-morning nap. Honestly, we couldn’t argue with either of those.

As many of you know, our growing season doesn’t start in the spring—it starts in November. While most people are gearing up for the holidays, we’re planting the first seeds for the following year’s crop. From that point forward, the 7-day work weeks begin and don’t stop until the greenhouse closes for the season.

Between planting, transplanting, watering, fertilizing, scouting for pests and disease, maintaining equipment, helping customers, and keeping thousands upon thousands of plants happy, there really aren’t many days off around here.

So Monday belongs to Mallory.

Enjoy the pedicure. Enjoy the nap. And don’t answer your phone.

We’ll see everyone again on Tuesday! 🌱❤️

Our fearless leader was in full OCD mode today 🙄… inspecting, organizing, spacing, checking leaves, and making sure every single mum is exactly where it needs to be.

Every mum is organized and potted based on bloom week, and when the timing is right they’ll head out to the mum field!

Most people don’t realize mums are actually bred and programmed to bloom during specific weeks based on daylight hours. As the days get shorter, the plants know it’s time to start setting buds. That’s why growers carefully select varieties by bloom timing so fields are exploding with color right when fall season hits.

But getting them there takes constant attention. Rainy stretches like what we all just experienced can create the perfect environment for fungal disease, and an outbreak can wipe out an entire crop worth tens of thousands of dollars before you even know what happened. We constantly inspect foliage, monitor plant health, improve airflow, and proactively treat to protect the crop. We even use systemic treatments that help strengthen the plant internally.

Growing giant, healthy mums isn’t luck. It’s months of timing, science, monitoring, and nonstop care.

Mum growing season has officially kicked off at Green Valley Harvesters! 🌼

Last week we planted the first 400 mum plugs of the season, and this week another 2,000 are going in! Before you know it, the grow field will be packed wall-to-wall with color for fall. We have over a thousand colorful ornamental cabbage/kale, huge Celosia and ornamental peppers.

One thing a lot of people may not know is that we grow most every single mum/plant we sell right here at Green Valley Harvesters. From tiny plugs to the huge fall mums you take home in September, we handle the growing ourselves every step of the way.

Behind the scenes, growing giant fall mums is part science, part art. Our mums are grown using computer-controlled irrigation systems and specialized monitoring equipment that constantly measures fertilizer levels and water quality. We carefully fine-tune nutrition down to just a few parts per million in every drop of water the plants receive. That level of precision is one of the biggest reasons we’re able to grow the massive, premium-quality mums we’re known for every fall.

Mums are one of the best plants for fall color because they thrive in cooler temperatures, bloom for weeks, and absolutely explode with color when the autumn weather arrives. With proper watering and sunshine, they can stay beautiful well into fall.

It may feel early to be talking about fall mums… but around here, mum season starts in spring! 🍂

We have been cracking up hearing people ask about our U-Pick Blueberry season before we were even thinking about blueberries yet. 😂

Things have finally slowed down enough for us to come up for air, so we decided to take a stroll up to the blueberry field to see how things were coming along…

And holy blueberries!!! 🫐

The bushes are absolutely loaded and the berries are coming along beautifully. We are anticipating a VERY full season with some of the biggest, juiciest, best-tasting blueberries around.

Still a little too early to pick just yet, but based on what we’re seeing right now… blueberry season at Green Valley Harvesters is going to be a good one. Stay tuned because it’ll be here before we know it!
