~ Don’t you just love this hobby? The seasons changing can only mean another miniature garden and now you can make one for the indoors! Do you want a wee beachy-garden scene to get you through the cold months? Or, create a miniature gratitude garden for Thanksgiving? Let’s recap what you need to know, and then follow with a few examples of the different indoor miniature gardens we’ve grown over the years.
Ten Golden Rules are from The Houseplant Expert, Dr. D. G. Hessayon, my favorite go-to book for indoor plants and a great reference for your bookshelf. Here’s a quick summary of his top 10 adapted for miniature gardening.
1. Don’t drown them. Roots need air as well as water. Let the soil dry out until barely damp. Put your finger down into the soil about 1” deep to test and yes, your finger is still the best way.
2. Give them a rest. Plants need less water and feeding in the winter. Some plants may not look as good, or need cutting back, before the new growth signals their return. Be patient and follow the plant’s signals.
3. Accept the loss of “temporary” plants. Some plants are not meant to live more than a season or two. Some miniature gardeners treat outdoor plants as short-lived houseplants during the winter. The Jean’s Dilly Dwarf Spruce, or the Pixie or Pixie Dust, is often used this way because they are true miniature Christmas trees.
4. Give them extra humidity. The average houseplant needs more humidity in the winter as the forced-air heat dries out the air quite quickly. By misting or grouping your houseplants around your miniature garden, you can maintain a better level of moisture in the air around the plants.
5. Add light. There are all kinds of plant-friendly light bulbs that can fit regular lamps, find them at your local hardware store or online. Instead of trying to position the miniature garden in the window, now you can put it anywhere as long as you have a lamp on it. Use a timer to turn it off and on for at least six hours a day, 8 to 12 is ideal. Shop lights come in a variety of sizes as well and many are available as a plug-in (as opposed to hard-wired.)

5a. Direct Sunlight. Some indoor plants enjoy a dose of direct sun but do so if you know for sure that the plant will enjoy it. Otherwise, use a sheer curtain to diffuse the direct sunlight to make it safe for all your plants. ALSO, watch that sunlight beaming into your windows in the spring and the fall. As the sun moves higher in the sky in springtime, and lower in the sky in the fall, the direction of the sunbeams will change inside your house too. All of a sudden you’ll may a sunbeam beating down on your miniature garden that wasn’t there a couple of weeks ago. This is where that sheer curtain comes in handy again.
6. Treat trouble promptly. With Google at our fingertips, there is really no reason not to be able to identify a plant-problem quickly and easily. State the problem plainly; name the plant and search under Google Images to find it faster. For example, “brown spots on parlor palm leaves.” Search at least two or three sites to get a better perspective of the solution. Not everyone is an expert out on the Internet, most often the most simple and natural solution is best.
7. Know when to re-pot. When the plants start to look sickly after a couple of years, then it may be time to re-pot. Look for the roots growing out of the bottom drainage holes to know when.
8. Choose wisely. Right plant, right place. You can’t grow a sun-loving plant in a dark corner nor can you grow a shade-loving plant in front of a sunny, southern window.
Recommended Tools:
- Water can with a long, narrow spout to get the water through to the bottom of the plants. Get used to how it pours before using indoors or you’ll make a big mess the first time.
- Mister – but know which plants like more, which like less.
- Saucers AND protective pads with plastic on one side, felt on the other. Don’t trust any pot or saucer on your good wood surfaces. Use an extra moisture-barrier-pad recommended for plants with a plastic backing to avoid wicking. I’ve seen cork mats, but I’m not sure if they wick moisture or not.
- Organic fertilizer. Avoid chemical fertilizers of any kind, the plants just don’t care for it and it builds up in the soil.
- Soft sponge for cleanup.
- Old kitchen spoon for re-potting and fork for raking.
- Scissors or small garden shears – or both.
- Indoor Potting Soil – Use potting soil without any extra fertilizers or moisture-retaining polymers. Look for an organic, indoor potting mix for a general-purpose soil that will be okay for most of your houseplants. Succulents, cacti and African Violets need more drainage material, like vermiculite or Perlite.
You will notice that there is not a lot of variety yet in the plants that are shown here. That is because I killed the rest of them. Yep. I tend to kill indoor plants a lot better than our outdoor plants. The plants shown here are some of the tougher plants I have found for gardening in miniature. For the most part, I’ve included the plant’s names, and the growing notes under each photo.
