How To Plant Petunia Hanging Basket

Petunias thrive in regions with direct sunlight. Look for petunia varieties that produce flowers on long, flowing stalks, such as cascading petunias. Petunias are simple to plant in hanging baskets as long as you choose a robust container with at least one drainage hole.

A light-weight commercial potting mix should be used to fill the container because it will help the drainage. Never use garden soil because it soon compacts and is too heavy for adequate drainage. When planting, incorporate a slow-release fertilizer into the potting soil.

How is a hanging petunia basket grown?

Wave petunias are frequently grown in hanging baskets due to their propensity for spreading and continuous blooming. Wave petunias can be planted alone (single color), with other Wave petunias of different colors, or with other annuals to make a lovely bouquet of flowers and foliage.

Plants that grow well with Wave petunias in a hanging basket

Petunias in the wave family grow quickly. Therefore, it’s critical to pick companion plants for Wave petunias that can sort of stand on their own.

Here are a few illustrations of annuals that you would frequently find planted alongside Wave petunias. These plants either have height or are similar spreaders, which prevents Wave petunias from engulfing them. They need the same amount of sunlight and water.

Trailing Verbena

Wave petunias go very nicely with trailing verbena. The different bloom and foliage of these plants contrast well with Wave petunias, which will grow and cascade over the side of the basket like these plants do.

You also have extra color and design options if you decide to combine your Wave petunias with trailing verbena. Wave petunias come in a range of hues, but Trailing verbenas have some stunning bi-color blossoms that make them a wonderful companion plant for Wave petunias in a hanging basket.

Calibrachoa (Million Bells)

Another robust grower that Wave petunias shouldn’t supplant is Million Bells.

Although Million Bells are a relative of Wave petunias, they have smaller flowers that provide the hanging basket some diversity.


In search of height? A Wave petunia basket looks fantastic contrasted with geraniums. It looks nice to have a hanging basket with Wave petunias spilling over the edge and a Geranium growing up the middle.

Both plants can receive the sun they require to put up a spectacular display because geraniums can tolerate the sun as well.

Sweet Potato Vines

A common “spiller” for hanging baskets is sweet potatoes. Dark black and a yellowish green are two common colors. These accent hues work beautifully with a Wave petunia basket.

How are hanging baskets planted?

top advice

  • To keep the hanging basket steady, place it on top of a broad, short pot.
  • To assist retain water, place a circle of polythene at the base.
  • The trailing plants’ root balls should be wrapped in paper before being inserted through the holes.
  • Put a tiny plastic container towards the basket’s center so it can serve as a watering reservoir.

How do you take care of petunias in a hanging basket?

Hanging baskets will require more regular maintenance because water and nutrients leak out of them more quickly than for plants in the ground.

How do you keep petunia baskets blooming?

Petunias consume a lot of food. To encourage additional blooms, add a water-soluble fertilizer with a higher concentration of phosphorus and potassium to the slow-release fertilizer you applied when you were planting. Many contemporary hybrids are self-cleaning, unlike older kinds that need deadheading for ongoing flowering.

How many petunias are in one hanging basket?

It depends on the size of the basket and the plants’ mature size. Use four to six starter plants in 4-inch pots for a 12 to 14-inch basket.

How often to water a petunia hanging basket?

The best water for petunias is constant water. Checking hanging baskets periodically is necessary since they dry out rapidly. It’s time to water if the soil feels dry 1-2 inches down. This can include watering once or twice each day during warm weather. Reduce water use and avoid letting the soil become moist in cooler temperatures.

Do petunias like shade or the sun?

Petunias require at least 5 to 6 hours of adequate sunlight, and they thrive in locations that receive full sun all day.

While soil doesn’t have to be incredibly rich to produce good petunias, it does need to drain well.

It’s always beneficial to condition garden soil with organic matter, such peat moss, compost, or manure.

Use a rototiller or garden fork to incorporate it into the soil 8 to 10 inches deep.

increases the capacity of light, sandy soil to hold moisture and nutrients while also aiding in the opening up of heavy clay soil, which enhances drainage.

To answer the first portion of your question, petunias can live for two or three years, but they typically behave like annuals because they can’t withstand the harsh winter weather. See more below on that.

It’s challenging to accurately assign a timeline to each particular blossom in the second part. Despite the fact that they don’t have a long lifespan, the plant produces so many of them that you might not even notice.

In a 14-inch hanging basket, how many Wave petunias are there?

What is the recommended number of Wave petunia plants for hanging baskets and containers? Three Wave plants in a 10 to 12-inch basket or container are what we advise. Your Wave petunias will compete with other plants for the nutrients they require to spread and cascade over the sides of a tiny basket or container.

How can a hanging basket appear fuller?

In the container or basket, there is a lot of competition for nutrients and root space. Since hanging baskets are designed to receive frequent watering, the plants may extract nutrients from the soil more quickly than they would be able to in other containers.

A slow-release granular fertilizer must be incorporated into the potting soil. This makes it possible for all of the plants in the basket or pot to receive the maximum quantity of nutrients, combined with the addition of a liquid fertilizer at half strength once every few weeks or so.

These plants can grow seriously, lushly, and produce more blooms than they otherwise could when they receive those crucial nutrients on a more regular basis. To achieve the look you’ve always wanted, water consistently and vigorously.

You can find lovely hanging plants for any room much more easily than you might think. They may provide a lush, colorful, scented atmosphere that gives any place a better-than-ever sense of freshness and naturalness.

Can I plant as many petunias together as possible?

Although petunias can be planted at any time of the year, spring planting is the most popular. As long as there is no possibility of a frost, you can plant petunias. With the correct circumstances and maintenance, the plants will last into the fall. Remember that petunias planted later in the growing season won’t have highly established root systems and will require more frequent watering to withstand warm weather.

Containers make sense given that the soil dries out and heats up rather rapidly and petunias thrive in dry soil and warm weather. Petunia plants don’t care too much about the pots they live in. The plant will flourish as long as the container includes a drainage hole and room for the roots to spread out. In a 12-inch pot, aim to place no more than three petunias.

Unglazed ceramic and terracotta planters with pores allow the soil to dry out more rapidly, which is ideal for petunias. However, if the soil is drying up more fast, you will need to water the plants more frequently. As long as they include drainage, non-porous planters like glazed ceramic and plastic are also suitable options.

What season is ideal for planting petunias?

One of the most widely used flowers in Louisiana is the petunia. They can be planted in late winter or early spring for warm-season color or in the fall for cool-season color. In local garden centers, you can discover a variety of petunias, as you can with practically any bedding plants these days.

Plant petunias in late January through mid-March for greatest results, or from late September through early November. South Louisiana petunias perform well in the winter. The severity of our winter has a big impact on how well they perform.

Petunias are available in a variety of floral colors. Both single- and double-flowered petunias are available. In general, single-flower forms are more durable over time than double-flower forms.

The following are some “best management methods” to help you enjoy your petunias from now until late spring:

Make sure the garden bed is properly prepared to provide for adequate internal drainage and aeration.

How should soil be prepared for petunias?

Petunias thrive in full sun, although they will blossom in bright, indirect light. Petunias prefer rich, well-draining soil that is neutral to slightly acidic (pH 6.0 to 7.0). Ideal soil is light and sandy.

Dig down 6 to 8 inches to loosen the dirt, add some organic matter, and then level it off. Each petunia seedling needs a hole dug that is around the same size as its container. Each one should be carefully removed from its container, placed in its hole, and the dirt should then be softly pressed in around the roots. The seedling should not be planted any deeper in the ground than it was in the container. generously hydrate.

Plant seedlings in groups of three or more, or place them in rows 8 to 12 inches apart if space is limited. Pinch back the primary stems of transplants after they reach a height of 6 inches to encourage the growth of side stems and bushiness. Because they are slower growers and have finer textured plants, the new, tiny milifloras can be planted as close as 6 inches apart. Before the rain, add a teaspoon of all-purpose, slow-acting granular fertilizer to the soil surrounding each newly planted seedling. The petunias will receive reliable, essential nutrition from this throughout the growing season.

Petunias benefit from an energy boost from diluted liquid fertilizer that is occasionally poured onto the soil or sprayed on their foliage because they are such prolific bloomers from late spring to mid-fall. Add the granular, slow-acting fertilizer to the soilless growing medium of containerized petunias to feed them. If not, sprinkle diluted liquid fertilizer on your lawn from time to time. Because of their thin roots, petunias require consistent moisture to survive. They won’t require as much watering if they are in organic-rich soil. Petunias in sun-filled containers require daily watering, especially those in clay pots.

What do you put in the hanging baskets’ bottoms?

Line the basket with a material that will help the soil maintain moisture before adding dirt and the plants. Options consist of:

  • Coco coir liners are thick, durable, and absorbent since they are made from natural coconut husks. In order to keep the soil moist, it will store water and gently release it. Additionally, they have a pH balance that helps to maintain healthy soil, and they are biodegradable, so they won’t harm the environment.
  • Even though it’s not as environmentally friendly, a plastic bag can be used as a temporary hanging basket lining. To limit the amount of moisture that evaporates along the sides, put holes to the bottom and cut it up so that it fits easily and coverlessly in the bottom of the basket. If your plants prefer a dryer environment, only line the sides of the basket. As a result, water can readily drain to the bottom. Lining the interior of the entire hanging basket is a good idea for plants that want to stay damp.

Should I line my hanging baskets?

Mix the compost thoroughly with the recommended quantity of slow-release fertilizer and water-retention crystals. If the compost is dry, put in some water as well. The plants should be watered in advance and given time to drain.

  • A thick layer of moss or another loose liner should be placed halfway up the basket in a large pot to balance it. Just enough compost should be added to cover the basket’s base.
  • Push three to four trailing plants through the wire to “place” them in the basket’s sides. To prevent the compost from leaking out until the plants are established, make sure the lining material is well fitted around the base of the plant.
  • More compost should be added, and it should be carefully pushed down over the plant roots.
  • Continue to add compost, liner, and plant layers. Usually, two layers of plants, evenly spaced out along the basket’s sides, are sufficient.
  • To prevent the compost from escaping, make sure there is enough liner around the base of the plants and that there are no holes in it.
  • Add extra liner and plant the top of the basket once the sides have been planted.
  • Working them in between the root balls of the plants that are in the sides, gently push the plants into the top of the basket. By this point, the basket may be quite crowded, so add compost around the roots as needed.
  • Make sure the compost’s surface is free of any visible roots.
  • Before hanging the basket up, give it plenty of water and allow it to develop for a few days in a chilly greenhouse or other protected area.
  • Plant the top after adding compost to the pot.
  • When applied along the sides, trailing plants should be oriented toward the pot’s edge.
  • After you’ve planted the pot, give it plenty of water and give it a few days to develop in a cool greenhouse or other protected area before hanging it up.
