Which Season Can You Grow New Guinea, Impatiens Plant?

Planting New Guinea impatiens outside in late April is ideal.

How To Grow New Guinea, Impatiens Plant

The best time to plant New Guinea impatiens outside is in late April. Identify the anticipated date of your last spring frost and plan to plant two weeks later. When planting these annuals in gardens, space them apart by the same amount as the mature plants’ width. (Vigorous varieties may need a bit more space.) Make a hole twice the size of the root ball. When planting, amend the soil with compost and apply a slow-release fertilizer.

Plant your New Guineas during the more fantastic hours of the day, and give them a good watering right after you put them in the ground. Cover around the plants to decrease water loss during the hot summer months.

New Guinea Impatiens Care

New Guinea impatiens are sensitive to their environment because they are particular about the quantity of nitrogen in the soil and how much water they receive. But the reward is huge: given the right care, these plants will blossom into a magnificent display of tropical flowers.


Pulling the ends of branches while the plant is young might assist in steering development into a more beautiful form. Impatienses that are lanky can also be clipped to a leaf node, but only up to 6 inches at a time. Although New Guinea impatienses drop their petals organically, removing them throughout the season will encourage flowering into the autumn. This cleaning is also helpful in preventing the formation of Botrytis fungal mold, which can form on dead flowers. Simply pinch the stem back, just above the first leaf pair, to eliminate wasted flowers. If you have planted impatiens, shaking the container may cause old flowers to break off.


The majority of cultivars are propagated through plant cuttings. Before cutting 2 to 3 inches from the tip of a healthy-looking stem, clean your garden shears with alcohol. Remove all the leaves, excluding the top two. The cutting should be placed in wet potting soil, and if possible, the bottom of the container should be heated with a waterproof heat pad designed for plants. The majority of impatiens in New Guinea is sterile hybrids that cannot be grown from seed. Some varieties, like the Java and Divine series, may have done so, but it took work. Propagation of the variants can be limited if they are patented.

Grow your New Guineas within approximately 10 to 12 weeks before you intend to transplant them outside (about 2 weeks after the last spring frost). Put a starter tray halfway with a seed-starting combine, and then fill each compartment with a pair of seeds. Because New Guineas require sunshine for germination, only gently cover the bases with dirt. Cover the tray with plastic after spraying the seeds. Please place it in a sunny location, moisten the soil, and replace the plastic after the seedlings have two leaves. Allow the young plants to mature indoors until the weather warms up enough to bring them outdoors.


New Guinea impatiens like a slightly acidic soil pH, in the range of 6.0 to 6.5, but are not overly picky. The blooms require soil with adequate drainage that retains moisture long enough for the roots to absorb. Because New Guinea impatienses are strong eaters, improve the soil with plenty of organic material before planting. Give your flowers a healthy sip of water after they’re in the ground to assist them in establishing themselves.


New Guinea impatiens flourishes when watered on a regular schedule. If you leave them moist for a lengthy period, they start to stop flowering and may die. Although New Guinea impatienses are not drought-flexible, sustained damp soil conditions might cause their crowns to decay. If at all feasible, water them from the bottom instead and use a drip hose.


Impatiens from New Guinea do not require a lot of fertilizer. Simply apply a slow-release fertilizer to the soil before planting them in a flowerbed, and you should not need to fertilize again. A biweekly application of water-soluble fertilizer is beneficial for container plants in the backyard.


New Guinea impatienses flourish in partial shade (between 2 and 6 hours of sunshine daily). They thrive in the early light, midday shade, and eastern exposure. However, these tropical beauties can survive both shades and full sunlight should be noted that too much sunshine, especially when paired with heat, may increase their water requirements, may injure the leaves, and may restrict the size and quantity of blooms.

Temperature And Humidity

It should be noted that excessive sunlight, particularly when combined with heat, may raise their water needs, harm their leaves, and limit the size and number of blooms.

They flourish in climates with daytime temperatures of 70 to 85 °F and nighttime temperatures of 55 to 65 °F. They will stop producing new blossoms when the nighttime temperature is 70 °F or above. High humidity is beneficial to New Guinea plants because it reduces water loss via the leaves.

Pests And Dieses

New Guinea impatiens, luckily, are resistant to downy mildew, which might quickly wipe out other impatiens varieties. Typical garden pests like aphids, thrips, caterpillars, and spider mites can enter New Guineas, although they are usually pest-free. While these tropical plants desire a lot of water, they are also prone to bacterial root rot. This can happen in poorly drained soil or containers without a drainage hole.

Common Problem With New Guinea Impatiens Plant

Like other types of flowers, New Guinea impatienses are susceptible to overheating, and the ailment border necrosis. Although brown necrosis spots on leaves can be unsightly, they are not harmful. Making sure the planting area receives enough color is the easiest approach to avoid this.


They are generally plants that like shade and hydration. Impatiens demand healthy, well-drained soil with a high organic matter content. They shouldn’t be put outside immediately away since they are quite susceptible to cold. Common flower colors include white, red, pink, violet, coral, purple, and yellow.
