Ready to grow your dream garden but not sure how to pick the right seedlings? Don’t sweat it! We’ve got your back.

Let’s answer some of the most common questions: How many seedlings should I grow? What’s the best time to plant? How long does it take for my veggies to grow? Can I grow [insert plant] in [insert state] right now?

Grab your gardening gloves, and let’s break it down step by step! 🌱✨


1. How Many Plants Can You Grow on a Tower Garden?

First things first—know your tower! There are two main options:

  • Tower Garden FLEX – 20 regular growing spaces.
  • Tower Garden HOME – 32 growing spaces (16 for regular plants + 16 for baby greens).

Feeling extra ambitious? Go for the Family Garden—that’s THREE Tower Garden FLEX systems with extensions for a whopping 84 growing spaces!

You can also customize your setup with these extension kits:

  • Regular Extension – 8 regular spaces.
  • Baby Greens Extension – 32 baby greens spaces.
  • Combo Extension – 4 regular + 16 baby greens spaces.

The possibilities are endless. Now, let’s talk about crop size.


2. Size Matters: Plan Your Crops Like a Pro 🥦

Crop size is key! Here’s a cheat sheet:

  • Small & Medium Crops – Load up your Tower with as many as you want. Think herbs, lettuce, and greens.
  • Large Crops – Keep it to 6 max if you’re growing outdoors. Indoors? Skip them unless you want a tomato jungle taking over your living room. 😅

Large crops like tomatoes, squash, and cucumbers need extra care, so start small if you’re a newbie.

Pro tip: Use the Crop Size Filter in the store to find the perfect fit for your setup.


3. Pollination: Time to “Bee” the Bee 🐝

Here’s the buzz: plants like tomatoes and cucumbers need pollination to produce fruit.

  • Outside: Nature does the work for you with bees, bugs, and wind.
  • Inside: You’ll need to hand-pollinate. Don’t worry—it’s super easy and takes just a minute or two. Check out this video for a quick how-to!

Not interested in playing bee? Stick to greens, herbs, lettuce, and flowers—they don’t need pollination.


4. Growing Season: Beat the Heat (or Cold) 🌡️

Before you start planting, think about your local weather:

  • Hot Summers (90°F+)? Use the “Heat Tolerant <95°” filter to find heat-loving crops.
  • Chilly Spring or Fall? Check the “Cold Tolerant” filter for frost-friendly options.
  • Middle-of-the-Road Weather? Most crops will thrive. You’re golden! 🌞

5. Tomato Talk: Pick the Right Type 🍅

Tomatoes come in three categories. Choose wisely!

  • Determinate (Bush Tomatoes) – Compact and grow to about 4'. Great for small spaces!
  • Dwarf Indeterminate – Keep producing fruit without taking over your life (or living room).
  • Indeterminate (Vining Tomatoes) – These keep growing and growing...and growing. Expect a steady tomato supply all season long.

6. Time to Harvest: Plan Around Your Schedule ⏳

Short on time? Use the Time to Harvest Filter to pick crops that match your timeline.

If you’ve got 12 weeks, choose crops with a harvest time of 6–8 weeks so you can enjoy the fruits (and veggies) of your labor before life—or the weather—changes on you.


7. How Many Seedlings Should You Grow? 🌿

Ah, the ultimate question! The answer depends on your eating habits and trial and error. Here’s a starting point:

  • Lettuce: 6–8 for a salad-loving family.
  • Greens: 1–2 of each variety.
  • Herbs: 1 of each variety.
  • Fruits & Veggies: Stick to these guidelines (and no more than 6 large crops per Tower):
    • Celery: 1–2
    • Broccoli/Cauliflower: 1 each
    • Beans/Peas: 4+
    • Cucumbers, Melons, Squash, Eggplant: 1 each
    • Peppers: 1 of each variety
    • Tomatoes: 1 of each variety (no more than 3 per Tower for sanity’s sake)
    • Strawberries: As many as you want—because who doesn’t love fresh strawberries?! 🍓
