Gardening in Shade and Solving Your Garden Maintenance Problems - Ep. 196
I hear from a lot of frustrated would-be gardeners at the farmer’s market stand who say they just don’t have enough sun in their yard to be able to grow anything. Of course, they can always go to maximum effort by growing in smaller containers and moving them around the yard as the season progresses to catch the light as the sun shifts, which is a lot of work, but it’s also very possible that many of these potential gardeners have more sun than they think. And this goes for my gardeners who are apartment dwellers or who live in condos with only a patio or balcony space to grow on. You might be able to grow more than you think. And, there actually are a selection of vegetables, fruits, and herbs that will do just fine in part-sun and others that will tolerate it if you have a little patience with them. Today on Just Grow Something we’re going to define full sun, part sun, part shade, and shade so you have a better idea of what is actually possible in some areas of your yard and then we’ll go over the choices available if you truly do have less than full sun. Plus, we’ll go over your answers to the April question of the month and explore how we can solve some of the most common garden maintenance struggles you and I both have. Let’s dig in!

Preventing and Controlling Foliar Disease in the Garden - Ep. 195

Preventing and Controlling Foliar Disease in the Garden - Ep. 195
Foliar diseases in both vegetable and fruit plants can significantly impact our yield and the quality of that yield if left unmanaged. If you’ve ever had powdery mildew on your cucumbers or early blight in your tomatoes, you know exactly what I’m talking about. Even though the disease is affecting the leaves, the interruption of photosynthesis by the fungus affects the fruit development, and then the disease will jump from the leaves to the fruit and then we’ve got a real mess on our hands. And sometimes we can get one disease under control only to have another one swoop in and take out our plants before we even get any kind of harvest. This is especially true if you live in an area that is very humid or you have spring weather that bounces from warm and humid during the day to cool overnight with very little air movement and lots of rain. Warm temperatures, high humidity, lots of moisture and prolonged leaf wetness are the ideal conditions for fungal growth. Today on Just Grow Something we are going to cover the different ways we can prevent fungal diseases from taking hold in our garden plants, what signs and symptoms to watch out for, which plants are most susceptible to fungal diseases, and which ones don’t usually have much of a problem with them. There are lots of things we can do as gardeners to prevent and minimize the occurrence of foliar diseases so we get the best yield possible from our plants. Let’s dig in!

Growing Strawberries - Ep. 194

Growing Strawberries - Ep. 194
We talk a lot about growing vegetables on this show but, in truth, I am a huge fruit eater. I love fruit, either on it’s own or on a salad, in smoothies, in desserts, love it. Being someone who is a proponent of sustainable agriculture I also prefer to get my fruits locally if I can. That’s not to say I don’t always have bananas in this house and that I don’t love a good Mandarin orange, but if I can grow it myself, I feel much better. Fruit trees can be intimidating, and they can be temperamental if you don’t have the right soil conditions, berry canes and bushes also require a bit more care and maintenance. Which is why strawberries are the sort of gateway fruit for vegetable gardeners. You can plant them in ground or in containers, you can grow them in many different climates, and even minimal effort in maintenance will improve the yield dramatically. So, today on Just Grow Something we’ll talk about growing strawberries. Whether you’ve got an in-ground bed, a raised planter bed, or just a container on your back deck, we’ll talk about the soil and nutrient requirements, planting in the spring or the fall, maintaining the bed, potential problems, and more. Let’s dig in! Question of the month for April: What have you struggled with the most in terms of garden maintenance and did you find a solution? Maintaining soil nutrients, reducing weed pressure, proper mulching, proper watering techniques, whatever your garden needs that you struggle with or that you used to struggle with and have found a solution. Answer the question from within Spotify, reply to this week’s email newsletter on Friday with your, answer in the Facebook group or send me a DM on social media. You have until April 30th to give me your answer and share your struggles and solutions with your fellow gardeners.

Proper Soil Temperatures for Transplanting - Ep. 193

Proper Soil Temperatures for Transplanting - Ep. 193
Using the last frost date in spring or our average air temperatures might be a good guideline to start with when figuring out when to plant the garden, but a better method for knowing when it’s actually time to sow those seeds or transplant those plants is the soil temperature. Even though the air temperatures may be warmer than usual, the soil knows the truth. If that soil is cold and wet, or might be that way in the next ten days, your tomatoes, or peppers, or whatever, are not going to be happy sitting in chilled soil, no matter how warm the daytime air temperatures get. But, your sugar snap peas and lettuce might be thrilled. So, today on Just Grow Something we’ll talk about optimal soil temperatures for both cool season and warm season crops, for both seed germination and transplant growth, how to properly check your soil temperature, and where to find historic soil temperature data for your area so you can more effectively plan your planting dates and not be lulled into that false sense of security.

Amendments to Add in Spring for the Summer Garden - Ep. 192

Amendments to Add in Spring for the Summer Garden - Ep. 192
Back in November I talked to you about doing a soil test, using slow-release amendments in the garden to do their work gradually over the winter, and then doing another soil test in the spring to see how well it worked. Now’s the time in most areas to be doing that spring soil test before you start planting your spring or summer gardens. But, what do you do if that spring test shows the amendments you added in the fall just weren’t enough to fix the problem? This time around you’ll need something that works into the soil a little more quickly if you want the garden ready in time to grow a lush crop for spring and summer. And even then you may find the need to add some supplemental plant food to directly feed the plants instead of the soil to be sure you get a good harvest. So, today on Just Grow Something we’ll go over the organic amendments you can be adding to the garden now that will give the soil a quick boost and the possible ways to feed the plants directly while waiting for the soil to improve. Let’s dig in! Question of the month for April: What have you struggled with the most in terms of garden maintenance and did you find a solution?

Hardening Off Seedlings Before Transplant - Ep. 190
Hardening off is a process that helps plants adjust to the outdoor environment, preventing shock and ensuring they thrive once planted in the garden. Gradual exposure helps the plants acclimate to the conditions they will experience out in the garden or in their containers on your porch before you put them out there. Today on Just Grow Something we’ll go over the exact steps we need to take to harden off our plants prior to putting them out into the garden. This includes whether you’re growing them yourselves or if you’ve just brought them home from the nursery, garden center, or farmers market. Following these steps and displaying some patience will prevent the heartache of putting those plants out and having them fail. We’ll also talk about how to recover if your plants begin display signs of stress after they are already in their permanent home. Let’s dig in. Question of the Month: : “What is your biggest pest in the garden and how do you manage it (if at all)?” Leave a voice message from the link in the show notes, respond to the question in Spotify if that’s where you’re listening, send me an email, drop it in the Facebook group or in a DM to me on Instagram, Facebook or TikTok. We’ve already had some good discussions around this in the Facebook group and I will read all the answers on next week’s episode. You have until March 31st to get me your answer.

Straw Bale Gardening - Ep. 189

Straw Bale Gardening - Ep. 189
Years ago I had some straw bales I’d used initially as fall décor that ended up in my chicken coop. The bales were used partially as a wind break all winter and partially as a roost. Well, chickens do what chickens do when they roost and by the spring of the following year those straw bales were full of nitrogen-rich chicken poop and starting to fall apart. So, I moved the out of the coop, watered the down really well for about a week, and planted a bunch of plants into them. This was my first introduction to straw bale gardening and it worked wonderfully! The nitrogen from the chicken manure had kickstarted the decomposition process of the straw, providing essential nutrients for the microbes that do that work, and the decomp of the straw inside the bale created a fertile growing medium. I expanded the gardens quite a bit after that, as you all know, and haven’t worked with straw bales as a growing medium since. But this year, that changes. I’ve got a new spot I’m putting together behind my greenhouse with eight planter boxes already in place, but there’s also a fence at the back of that space I want to both cover and use as a trellis. I don’t want something permanent against that fence so I’m jumping back into straw bale gardening. Today on Just Grow Something we’ll talk about how to use straw bales as a growing container and medium. I don’t have naturally conditioned bales this year, so we’ll talk about the process I’ll need to go through to get those bales ready. I’ll also cover the benefits of gardening in bales, what to watch out for, what plants do well with this method, and how to maintain them. By the end of the episode I think you’ll be convinced that straw bales are an effective way to increase the growing space in your garden without needing a permanent solution. Let’s dig in!

Maintaining Fruit Trees, Bushes, and Canes

Maintaining Fruit Trees, Bushes, and Canes
If you’re planning to put in new fruit trees, bushes, or canes in your garden the best time of year, generally, is spring. We want the soil to warm up enough that the roots of the plants will begin to seek out water and nutrients as soon as placed in the ground with as little transplant shock as possible. But, if we have existing fruit trees, bushes, or canes then any maintenance on those trees should be done before the soil begins to really warm up and the plants come out of dormancy. This is usual sometime between late fall and early spring, which means most of the northern hemisphere is primed for these tasks right now. Today on Just Grow Something, we’re going to talk about those tasks and how to tackle them: pruning, fertilizing, and moving your established plants if it’s necessary to do so. This is one of those tasks that can scratch the itch for getting out into the garden when maybe it’s still too early to really be planting much and they’re tasks that are important for us to get the best yield possible from those plants.

Different Ways to Grow Potatoes - Ep. 186

Different Ways to Grow Potatoes - Ep. 186
Potatoes are a cool season crop, and most varieties need between 60 and 120 days to mature, so that means getting them in the ground as soon as the soil can be worked and giving them the time they need to grow. The great thing about potatoes is they can be harvested at any size, so it’s a crop that can do well in a short-season area and can also be grown in places other than big, long in-ground rows. If you have minimal space or you can only garden in grow bags or buckets, you can still grow potatoes. Today on Just Grow Something we’re talking about just that – what are all the different ways and places we can grow potatoes? They are such a versatile crop it makes sense to tuck some into your garden area no matter what size it is. Let’s dig in!

Heat Mats and Grow Lights - Ep. 185
This month we’re talking a lot about seed starting and we can’t talk about starting seeds without talking about heat and light. Seeds sprout more quickly and efficiently when they’ve got the correct soil temperatures and the easiest way to do this is with a seedling heat mat. It’s not a requirement, though, so we’ll also talk about some ways you can up the ante on the soil temperatures during seed starting without a heat mat. Once those seeds do sprout and you're nurturing those little seedlings the correct light can make all the difference, and usually even the sunniest window in your house just isn’t going to cut it. That means we need do a little investing in some lights to help our seedlings along. Today on Just Grow Something we'll explore soil heating options and various types of grow lights, including the most economical and even tabletop solutions. Let’s dig in! *Question of the Month: “What is your most successful crop and why?” This could be a specific variety of something that outproduces all the others, the plant that you love the most, or the crop that grows fantastically well for you without fail every single year. Whatever you consider your most successful crop in whatever way you consider it successful.

Soil Blocks and Flower Bars with Kathy Gormandy - Ep. 182

Soil Blocks and Flower Bars with Kathy Gormandy - Ep. 182
Soil blocking is a seed starting technique that uses small blocks of soil or seed starting mix. There are no containers, no small plastic cells, just the soil itself. The benefit of soil blocking is, of course, you’re not keeping a bunch of plastic containers around to start your seeds in, but also there is no chance for the roots of the seedlings to become bound by a container. The plants roots will reach the edge of the soil block and simply stop growing until the block is planted, the roots come into contact with more soil, and can take off growing again. This reduces the transplant shock. Today on Just Grow Something I brought back our flower farmer friend, Kathy Gormandy, to talk about how she uses soil blocking on her farm. We also talk about her new retail space, the importance of locally grown florals, and more. It’s a conversation that has me taking a second look at trying soil blocking again this year. Let’s dig in.

How to Choose a Plant Variety - Ep. 179

How to Choose a Plant Variety - Ep. 179
You may have an idea of what you want to grow in terms of vegetables in your garden – say zucchini and tomatoes, for example. If you open the seed catalog or website to the page for zucchini you may find as many 18 to 25 different varieties to choose from, each with their own unique set of attributes in terms of shape, size, color, growing conditions, disease resistance, pollination type, and more. Move on to tomatoes, well now you’re talking hundreds of varieties in different classes from cherry to beefsteak to sauce types. And that’s just one supplier. It can be overwhelming, and we can fall victim to the dreaded analysis paralysis – spending so much time gathering information while trying to decide that we fail to decide. Let’s take a little bit of the overwhelm out of the equation by defining what exactly it is we are looking for in each of the types of vegetable or fruits we want to grow before we even dive into the catalogs or walk into the garden center. If you’ve got a list of attributes you’re looking for ahead of time it makes it easier to make a decision about what will do well in your garden, meet your goals, and eliminate some of the distractions. Let's dig in. Don't forget to answer the question of the month for January: How do you plan your garden each season?

Choosing a Seed Supplier - Ep. 178
It used to be easy to just choose a catalog and order seeds because there were only a handful of choices and, generally speaking, unless you were going to the nursery or garden center to buy seed packets from a kiosk, you were ordering from a physical catalog that you actually got in the mail. But, nowadays, a simple internet search will yield thousands of results from companies all over the world and it’s a little bit more difficult to weed out the bad guys. So, today we are going to talk about ways to find a legitimate, established, verified seed company whether it’s online, through a catalog, or local to you. And what to do if you encounter a new small business that seems legit and you’d love to support them, but you also want to make sure you don’t get burned. I will also give you a list and links to my favorite suppliers over the years, including my very first catalog purchase. Let’s dig in! Question of the month: How do you plan your garden each season?
