How to care for basil

Light

Six to eight hours of direct sun a day. Indoors, a south-facing window or a grow light keeps stems compact; low light makes basil leggy and weak in flavor.

Water

Keep the soil evenly moist but never soggy, watering when the top inch feels dry. In hot weather potted basil often needs water daily, and midday wilting is a useful signal.

Soil

Loose, fertile soil with good drainage and a pH around 6.0 to 7.0. Compost worked in at planting holds moisture without staying waterlogged.

Temperature

Basil is a warm-season herb, so plant out only once nights stay above 50F. Growth stalls below that, and even a light frost ends your basil.

Feeding

Feed Basil Fertilizer through the growing season, mixed into your regular watering, from the first true leaves until your last harvest. Frequent picking uses up nutrients quickly.

Harvest

Pinch stems just above a pair of leaves once plants reach six inches, and remove flower buds as they form to keep new leaves coming.

Frequently asked questions

How often should I feed basil?

Every one to two weeks while it’s actively growing. Basil is harvested constantly, and every pinch removes leaves your basil has to replace, so it needs a steady supply of nitrogen to keep pushing new growth. Basil Fertilizer is formulated for that pace: a liquid feed mixed into your regular watering, so Genovese, Thai and sweet basil stay tender and productive through a full season of cutting rather than slowing down after the first few harvests.

How often should I feed basils?

Every 1–2 weeks in spring and summer, then every 4 weeks in fall and winter if you’re keeping plants going indoors or in a mild climate. Basil Fertilizer is a liquid, so it mixes straight into the water you already give your basil and feeding never becomes a separate task. Outdoor basil is an annual in most gardens, so the spring and summer schedule is the one that matters for most growers.

Will fertilizer change the flavor of my basil?

No. Basil Fertilizer supports leaf production, and the essential oils that carry flavor are your basil's own work. What feeding does is keep the leaves tender and plentiful instead of small and tough, which is what a hungry, over-harvested plant produces. The strongest flavor comes from the way you grow and pick it: harvest before your plant flowers, pinch the tips regularly to delay bolting, and give it full sun.

Is it safe to use on food crops?

Yes. Basil Fertilizer is made for an edible crop. It supplies the same mineral nutrients basil draws from soil, taken up through the roots and used to build leaves, rather than anything that coats or sits on the harvest. Water it in at the base of your basil as part of your normal routine, then rinse the leaves you pick as you normally would before using them in the kitchen.

Will this burn my plants?

Basil Fertilizer is a dilute liquid feed, and dilution is what matters here. Fertilizer burn happens when concentrated salts sit against the roots: too much product in too little water, or granules piled at the base of a plant. Mixed at the recommended dilution and applied every 1–2 weeks, the nutrients arrive in solution at a strength the roots take up as they water. Keep to that mix and water it in with a normal watering; if you ever mix too strong, flush the pot with plain water.

When will I see results?

Greener leaves and stronger new growth usually show within two to four weeks of consistent feeding. Basil grows quickly in warm weather, so the change tends to be visible at the growing tips first, where new leaves come in larger and a deeper green. The bigger payoff from Basil Fertilizer builds over the season: a plant that keeps producing after repeated harvests instead of thinning out by midsummer.
