Factors To Consider On How Often To Water Basil Plant

Watering basil plants may be quite tricky especially for newbies. Overwatering or under watering can stress or even kill basil plants.

Even though basil plants require sufficient watering, too much watering can predispose the plant to root rot. It can also predispose basil to plant wilting or make the plant distressed and this can attract pests that can destroy your basil.

So here are some major factors to consider when it comes to watering basil plants:

  • Temperature: If the temperature is high, more watering will be required and vice versa. If it’s raining season, watering will be less.
  • Indoor or Outdoor and Soil Type: Another factor to consider when watering your basil plant is if you’re planting indoors or outdoors. The type of soil used is also another factor (is it a well-draining soil or less draining soil). So, ask yourself, do you have your plant outdoors in nutrient-filled and well-draining soil? Or is your plant in a container and you have the container indoors?

To water basil correctly, let’s dig in further to learn how often to water our basil plant for both indoor and outdoor gardens.

How Often To Water Outdoor Basil Plant

For basil planted outdoors in the garden, watering should be done once weekly especially when it is raining season. But when the temperature rises and there’s an absence of rain, water your basil plant every 3 or 4 days. Also, consider the type of plant used. If it’s well-draining plant water more. If it’s soil that holds moisture very well, you should water less.

To reduce the stress of watering every time, you can simply enhance moisture retention of your soil. Do this by mulching the soil surface to reduce evaporation and increase water retention by the roots.

How Often To Water Container Basil Plants Grown Outdoor

Basil grown in pots or containers outdoors should be watered every 3 or 4 days. However, when it’s very hot, you will need to water more. Water the potted basil sufficiently until water drips out of the bottom holes.

Another tip is to do a soil moisture test by dipping your finger about 2 inches into the soil to check for soil dampness or dryness. This should be done mostly in very hot seasons. If the soil is dry, that’s a sign you need to water.

How Often To Water Indoor Container Basil Plants

Basil plant that always remains indoors should be watered every 3 to 5 days. However, you should make adjustments depending on the indoor conditions.

For instance, if your indoor basil container is placed close to the window where it receives some shaded light, you should adjust the watering scheme accordingly. Also, consider the heat, air conditioner, and humidity in your home.

However, basil grown indoors requires sunlight and the pots must have good drainage. Therefore, we recommend placing your basil plant close to a window.

It’s important you follow the right instruction for the recommended fertilizer to apply on your basil plant to avoid fertilizer burn.

    • Temperature: basil plants thrive well in temperatures between 50 to 80 degrees Fahrenheit. Avoid cold temperatures for basil because too much cold can destroy basil plants. Therefore, the basil plant is sensitive to frost. So, harvest your basil before frost. Also, don’t place your basil plants close to air conditioner vents, doors, or drafty areas.

    • Humidity: maintain and humidity area of about 40 to 60 percent for your basil plant.

    • Pest: whiteflies and aphids infestation is the most common pest that affects basil and they’re common to indoor basil plants. When you brush your basil leaves and you notice any white insects fly out of the plant, the plant may be infested with whiteflies. Make use of insecticidal soap to assist in controlling this kind of pest.

Overwatering is a problem that can be solved with a little knowledge of the plant. First of all, basil is a tropical plant, so you don't want to water it in the fall or winter. The best time to water it is in the spring and summer months.

But what makes basil plants so tricky is that they like to take up a lot of space. You can have a half-inch or even inch of soil on top of your basil leaves. It can be tricky to tell if your basil is too wet. The best way to find out is to cut off a leaf and taste it. If the leaf feels soggy or has any water on it, you need to water more often.

How do I care for my indoor basil plant?

The best way to care for your indoor basil plant is to give it the right environment and nutrients. It’s important to provide a light source that will help your indoor basil plant grow well.

If you want to give your indoor basil plant a boost, you should use basil tea instead of plain water. It contains more potassium and vitamins than ordinary water.

Indoor basil is usually started in trays or small pots in the spring and then transplanted into larger containers as soon as possible. Keep the plant watered but not overly wet. The soil should be able to dry out between waterings. You want to be sure that the plants are getting enough light. The light should not be too bright or too dim.
