Things You Can Do Now to Prepare for Next Dahlia Season

It’s almost winter time and hopefully you’ve dug your tubers (if you needed to). It’s time to enjoy the pictures and memories of a beautiful dahlia season!

However, if (like me) you’re just not content with sitting around, there are several things you can do now to prepare for an amazing dahlia season next year.

1. Prepare your soil. First off, take your soil test. Fall is the best time for soil testing on a regular basis. And it’s a really good idea to take the test around the same time each year. This way you can compare your progress from year to year. Fall is also a good time because any amendments you need to add take time to incorporate into your soil. The winter gives you time for this incorporation to happen.

After soil testing and adding any amendments you need, think about the texture and drainage of your soil. The handy thing about dahlias is that they tell you what they need in the soil. If your soil doesn’t drain well enough, you’ll see lenticles on your tubers. If the soil lacked food, the plant will grow small and spindly and usually the tubers will be small and not prolific. The visual appearances of the plant and tubers tell you what you need to know.

We are strategically adding compost and shredded leaves in several places this fall. We’ve identified where our drainage was poor and are working to correct it. Keep in mind that soil improvements can take several seasons. (This is why you want to take soil test each year— they help you to know if you are moving in the right direction.)

2. Research. It’s time for one of my favorite parts of growing dahlias— Deciding what varieties to add to my field for the next year. You can do this many ways— just add what’s pretty or decide you need more of a specific color or form. What suits you. Since we are a commercial cut flower farm, we are always looking for great cut flower varieties and varieties that thrive in heat. Those are the main priorities. After that, I usually assess my current collection to see what colors I need to increase. I try to ascertain what the color trends are going to be 2-3 years out because it can take that long to build up enough stock of a particular color.

I like to use Dahlia Addict (www.dahliaaddict.com) to begin my research as this site shows who has what and when it’s for sale. I also save pictures from Instagram all season long. Now if the time to review them. We all know that it’s easy to get dahlia mania and to want them all. But I’ve found that it’s good to have some goals when adding to your collection- this helps keep the dahlia hobby from breaking the bank! (I know you all know what I mean!)

Second, you can also research any problems you had- specific pests, not enough water available or if you had some climate type issues- how to deal with them. It’s beneficial to think through these things when you are not in the stress of the main growing season. There’s often more mental space to solve a problem.

3. Organize your game plan. One of the best things I did this past year was to stop mid season and get organized in regards to my feeding and pest management. I created a spreadsheet where we could record what we were fertilizing with each week and also what pesticides we used. This year, I’ll be adding a column to track what pests where in the field and when. We would scout each week but didn’t write down exactly what we saw. Lastly, we recorded what we sprayed for fungus issues too.

I know how hard it is to keep up with this stuff during the season so make your game plan now. Buy what you need before the season begins. Also figure out a strategy to ensure your don’t put off feeding and spraying your plants. They really do produce and give back to you when you take care of them. If you are a farmer- delegate this to an employee. That was also one of the best decisions I made. They have less floating around their minds in regard to the farm and can make the job a priority. This delegation ensured it got done on time every week! And our stem production and tuber harvest was better for it!

You can also set a record keeping system for other data in winter: storing pictures, recording bloom dates, stem counts. All those things you wish you had done at the end of the season. Go make a list and then work through setting up the systems you need through the winter.

It’s too busy in the middle of harvesting to invent a system so do it during the winter when it’s slow!

These are three of the best things you can do to ensure a great dahlia season for 2024!!
