Care & Harvest

🌡️ Temperature

Prefers warmer temperatures (70-85°F).

✂️ Pruning

Regularly examine the roots, trimming any brown or overextended ones beyond the yPod each month. To promote bushier growth, consistently harvest above the growth nodes on the stem (see Harvest below). Prevent premature bolting by promptly removing flower buds through pinching.

🔎 Plant Health

Our prevention and treatment techniques can help you ward off aphids, a frequently encountered pest. Similarly, regular root inspections and timely removal of leaves exhibiting brown spots are effective methods for managing common diseases like Root Rot and Downy Mildew.

🥬 Harvest

Regular harvesting contributes to the longevity of plants. You can either pinch off individual leaves or utilize clean shears to trim stems above the growth nodes. The growth nodes can be located just above the two largest leaves on a stem, where you’ll notice another set of small leaves or knobs growing between the stem and the larger set of leaves. By cutting the stem 1/4 to 1/2 inch above these nodes, you can encourage the small leaves to flourish into larger ones.

Why Grow Basil Indoors?

Basil is the herb of choice for some of the yummiest Italian seasonal dishes: from verdant, earthy pesto to delectable Caprese salads and even toasted bruschetta — it’s easy to see why it’s such a pantry staple. But why grow basil indoors?

Saves Money

Store-bought herbs can be expensive, and rather than getting maximum use out of your purchase, they can spoil rather quickly, sometimes even before you get to use them. Growing your own herbs like basil is a great way to save money, and ensures you always have access to flavorful aromatics, ready for any meal. Just pinch off a few sprigs whenever a recipe calls for extra flavor or a pretty garnish.

Easy to Maintain

Basil doesn’t require much effort to keep alive and well; it simply needs a sunny spot in your home — on your windowsill, a kitchen countertop, or even outside on a porch or balcony (or anywhere else with a Gardyn Home Kit). It’s also an ideal herb for novice gardeners due to its speedy growth cycle, as well as the fact that it’s relatively pest- and disease-free.

Clean Produce

Growing your own basil at home offers a great sense of security. Not only do you know exactly where your produce is sourced from, but you’ll also rest easy knowing that no nasty chemicals or pesticides have been used in its growth.

It’s So Much Fun

Cultivating your own produce at home is always fun — and a great learning experience for kids and adults alike. Seeing your crop grow from a tiny sprout to a full, luscious plant feeds into a greater appreciation of nature and understanding of sustainable food sources. And, more importantly, nothing beats the joy and pride that comes following a harvest!

What do You Need to Grow Basil Indoors?

Basil grows very well, with plenty of harvestable foliage. And it’s easy to grow, too — under the right conditions.


Basil thrives under plenty of natural, direct sunlight. If possible, get your plant in front of a south-facing window, with at least 6 hours of light per day.

Grow Lights (or any other artificial light)

If you’re using grow lights or fluorescent bulbs, you’ll want to position them around 2-4 inches from the top of your plant, ensuring that the leaves and the bulbs don’t touch. For more mature plants, make sure to set the lights a little higher to ensure that your basil will grow optimally. Aim for a light exposure of at least 10 hours a day. An alternating schedule between sun and artificial lighting can also work wonders for basil grown indoors.

Temperature Requirements

70-85°F (21-29°C). Keep the humidity high; mist your plant occasionally (especially in dry environments), and consider adding an air circulation fan that doesn’t blow directly onto the plant. Don’t let your plant get close to air conditioners or drafty windows, as these could dry it out quickly.

Pots and Containers

Your container of choice should allow for good air circulation and ample drainage (water stress can kill basil). Plastic or clay pots are both great options. Note that while clay pots do add a nice aesthetic, they may also leave permanent markings against surfaces, so that’s something to keep in mind. You can also upcycle things like food containers or metal cans to use as planters; just don’t forget to poke holes in the bottom to help with drainage.

Growing Medium

Basil grows best in well-drained, moist conditions. If you’re growing indoors, then a nutrient-dense potting mix is the best choice. Remember that the medium should be kept damp, but never waterlogged so you don’t get root rot.

How to Plant Basil Indoors

Basil can be grown indoors in a container or a hydroponic setup, either from seed or from an existing stem cutting.

Growing Basil from Seeds

To grow indoor basil from seeds, follow the same steps as you would for most other small seeds:

  1. Clear a warm, sunny spot for your basil plant.
  2. Prepare your growing medium in a container (a seed starting tray is a good choice), then pre-moisten it.
  3. Place the basil seedlings an inch apart (or 5-6 inches if you’re using a hydroponic system). Then, lightly cover the seeds with a sprinkling of dry soil.
  4. Keep the soil moist but never oversaturate it.
  5. For successful germination, maintain a temperature of 70-85°F (21-29°C) — a seedling heating mat might come in handy in this case.
  6. The seedlings should sprout within 5 to 10 days.

Growing Basil from Stem Cuttings

A simple and effective way to cultivate basil is to use stem cuttings from an existing basil plant:

  1. Start with a 4-inch stem with a few sets of leaves intact.
  2. Remove any leaves from the bottom two inches of the stem.
  3. Place the stem in water (cut-end first), and set it somewhere with plenty of sun.
  4. Once the roots are several inches in length (they should form within a week or two), transplant your newly rooted cuttings into a container or hydroponic system.

If you’re looking to ease your way into indoor basil planting, Gardyn’s yCubes are a great place to start. Each yCube contains non-GMO, pesticide-free seeds for a particular plant of your choice.

How to Care for Your Basil

Basil isn’t difficult to care for. In fact, it’s one of the easiest herbs to grow and enjoy. Get comfortable with the basics of basil care and maintenance, and you’ll soon be able to enjoy a year-round supply for your favorite recipes. And with careful tending, you might even end up with extra basil to dry, freeze, or share.


First — and this is important — pinch off the leaves from the tip of your basil as soon as the first two sets of leaves appear. Keep up with this process as more branch stems emerge (prioritize any unhealthy or stunted leaves). Doing this regularly helps your basil grow thick and lush, with plenty more stems for picking and harvesting later.


Important basil plants tips! When pinching or pruning your basil, be careful not to remove more than one fourth of its leaves. Doing so could hinder its natural growth process.


Basil requires about an inch of water per week. But be careful! Overwatering is a common issue among novice indoor herb growers. A good way to tell if it’s time to water your basil: stick your finger an inch into the soil. If the soil is damp, wait a day or two. If it’s dry, your plant is ready to be replenished with a drink.


Basil is a hearty plant that doesn’t require much fertilization. In fact, too much fertilizer could actually ruin its flavor and aroma. Overfertilizing can also lead to diseases and pest infestations. A light dosing of liquid fertilizer every four to six weeks is recommended if one wishes to fertilize.

Enjoy the taste of fresh, locally grown produce — minus all the backbreaking work and sweat. With Gardyn, indoor gardening has never been easier, more efficient, or more rewarding. Our indoor grow towers use automated lighting, watering, and patented Hybriponic™ technology to take care of the entire cultivating cycle — freeing you up to work on the more important things in your life.

Harvesting and Using Your Basil


Harvesting basil is a simple affair — best done by simply pinching off its leaves (essentially pruning). Don’t worry about damaging the plant; if it’s healthy, it’ll regrow what you take. Want to collect more than just a few leaves at once? Simply grab a pair of scissors and strip stems from the top down.

How to Use Your Basil

Now that you have your haul, it’s time to put it to good use. Some of our favorite ideas:

  1. Fresh basil leaves can be used to make salads and sandwiches. These can be chopped, sliced, or whole, depending on the recipe;
  2. Combine basil, olive oil, garlic, and pine nuts in a food processor and create a pesto;
  3. Try infusing a simple syrup with basil, then incorporate the syrup into lemonade or sweet tea;
  4. Muddle a few basil leaves in a cocktail shaker with simple syrup, lime juice, and rum for a delicious mojito;
  5. Add a few leaves of fresh basil to grilled vegetables or proteins for an added burst of flavor;
  6. Steep the leaves in hot water to make antioxidant-packed basil tea.

Put Together Your Own Basil Heaven

Growing basil indoors can be a fun and rewarding project, with delicious results. To ensure it flourishes, supply it with the basics: fresh air, sunlight, rich soil, and regular watering. Keep the soil moist but not soggy. A south-facing window will get your basil plenty of light, but if you don’t have one, you can use grow lights. Regular pruning will promote growth and keep your basil plant from getting leggy.
