Gardening 101: You can do it!

Gardening can seem daunting, but it doesn't have to be! We believe in "neighbors teaching neighbors," and that's exactly what our annual Gardening 101 workshop is all about.

This guide is based on a session we hosted in 2022;  it isn't a deep dive into every single gardening topic imaginable. Instead, think of it as your essential guide to understanding the basics, so you can confidently research your way to success! Our goal is to equip you with enough knowledge to know when you need help and how to find it, with your neighbors always ready to lend a hand.

1. Know Your Zone: Hardiness, Timing & Plant Selection

Understanding your hardiness zone is critical! This geographic area is defined by its average annual minimum temperature, a critical factor for plant survival. The USDA Hardiness Zone Map is your go-to resource. Each zone has sub-zones (Chicago is in 6a), and cities often have their own microclimates due to urban heat conditions.

Reading Seed Packets is Key! Seed packets are a treasure trove of information. Look for:

• Hardiness Zone: If it says "hardy to zone 6," it's likely suitable for our Chicago winters (especially for perennials).

• Planting Calendar: Many packets include a chart indicating the ideal planting times for various regions. For Chicago, May and June are often prime planting months.

Timing Your Seeds: There are two main ways to start seeds:

• Indoor Seed Starting: You can start seeds indoors typically 8-12 weeks before your area’s last frost date (Mother's Day-ish, for Chicago). This gives your plants a head start for the season ahead.

• Direct Sowing: You can typically plant seeds directly into the garden around May 15th, or when nighttime temperatures are consistently 50°F or higher. But remember, some "cold weather crops" like peas can be sown earlier, and some plants are best for fall planting. Always check your seed packet!

2. Sun Exposure: Mapping Your Light

Sunlight is a plant's fuel, so understanding the sun patterns in your yard is critical.

• Full Sun: Requires six or more hours of direct sunlight per day.

• Part Sun/Part Shade: Needs four to six hours of direct sunlight per day.

• Shade: Thrives with less than four hours of direct sunlight per day.

Practical Tip: Spend a day observing your yard at different times. Sketch out your property, noting obstructions like buildings, fences, and trees. Mark areas that receive full sun, part sun, and shade throughout the day. This "sun map" will guide your plant selection. For urban gardeners with smaller lots, you often have to work with the light you've got – so choose plants that will truly thrive in your specific conditions!

3. Understanding Your Soil: Texture, pH, and Nutrients

Soil is the foundation of your garden. It's a mix of minerals, organic material (living and dead), air, and water.

Soil Texture:

• Clay: Smallest particles, holds water and can be dense.

• Sand: Largest particles, allows water and air to drain quickly.

• Silt: Medium-sized particles, a good balance of water retention and drainage.

Soil pH: The pH scale (0-14) measures how acidic or alkaline your soil is. 7 is neutral, 0-7 is acidic, and 7-14 is alkaline.

• Test Your Soil: The best way to know your pH is with an inexpensive soil testing kit from a hardware or garden store. These also often test for nutrient levels.

• Chicago Soil: Our local soil tends to be slightly alkaline (often 7-7.5).

• Plant Compatibility: It's vital to choose plants that prefer your soil's pH. For example, some plants thrive in acidic soil (like blueberries), and if planted in alkaline soil, they may suffer from chlorosis (yellowing leaves) due to nutrient lockout, even if the nutrients are present. While you can try to amend your soil's pH, it's often an uphill battle, especially for an entire yard. It's usually easier (and more cost-effective) to select plants suited to your existing conditions.

Nutrients (N-P-K): Soil tests will also reveal your levels of Nitrogen (N), Phosphorus (P), and Potassium (K) – the three primary macronutrients plants need. The numbers on fertilizer bags (e.g., 10-10-10) indicate the percentage of each nutrient. Your soil test results will help you determine if and what kind of fertilizer your plants might need.

4. The Power of Compost & Fertilizers

Compost: This "black gold" is decomposed organic matter, and a gardener's best friend.

• Pros: Improves soil texture, makes nutrients more available to plants, increases aeration and drainage (yes, both!), supports beneficial soil microbes, buffers against soil changes, and allows you to repurpose kitchen scraps and yard waste.

• Cons: Not many! Can be heavy and costly to purchase in large quantities. Avoid using it in pond gardens. Ensure diseased plant material is well-broken down if you’re composting it.

Fertilizers: Synthetic fertilizers offer precise nutrient boosts.

• When to Use: Useful for correcting specific nutrient deficiencies (especially if your soil pH prevents nutrient uptake, like iron chlorosis in alkaline soil). Also helpful for container gardening where soil is finite.

Caution: Over-reliance can harm soil microbes and be costly. Quick-release fertilizers can lead to salt buildup in the soil, especially in dry conditions. Slow-release options are generally preferred for garden beds. And be thoughtful about where it comes from! Sourcing of fertilizers can be extractive, like kelp fertilizers may be destructively harvested.

If you've started seeds indoors or purchased plants from a garden center, you'll be transplanting them into your garden.

1. Know When to Transplant: The most important thing is to know when it's safe to put your plants outside. Many resources, like Johnny's (which offers an excellent online planting schedule calculator), can help you determine the ideal timing for various crops. Sometimes garden centers put plants out early, so be mindful of local frost dates.

2. Harden Off Your Seedlings: Your indoor-started plants have lived a pampered life! To prepare them for the elements (wind, direct sun, temperature fluctuations), you need to "harden them off."

   • Process: Gradually expose your seedlings to outdoor conditions over one to two weeks before transplanting. Start on overcast days, or place them in a shady spot initially. Increase their exposure to sunlight and wind each day.

   • Avoid Burn: Don't make the mistake of immediately putting tender seedlings in full, direct sun – you can burn them!

   • The Payoff: This slow acclimation significantly reduces "transplant shock" and sets your plants up for success.

3. Transplanting Technique:

   • Root-Bound Plants: If your plants are growing in plastic containers and their roots have circled the bottom (they're "root-bound"), gently remove the plant from its container. Tear off or prune the bottom layer of matted roots. This encourages new root growth and helps the plant establish itself more quickly in its new home.

   • Ease Shock: You can give your newly transplanted plants a light feeding to reduce transplant shock. Options include kelp fertilizers, fish emulsion (a fermented fish liquid, commercially available), or even a little molasses (a fermented sugar loaded with micronutrients). Just add a bit to your watering can.

4. LABEL YOUR SHIT! Seriously, do it! Especially when growing different varieties that look similar as seedlings. You don't want to confuse your hot peppers with your sweet peppers later on!

Gardening is a journey of learning and experimentation. Start by understanding your space, your soil, and your desired outcomes. Don't be afraid to try new things, and remember, your AGA community is always here to support you!
