Pollinating Abutilon Plants: A Guide to Boosting Yield

With their delightful bell-shaped blooms and maple-like foliage, abutilon are captivating ornamental plants. But did you know that many varieties also produce edible flowers and seed pods? Pollinating your abutilon properly is key to maximizing fruit production. This guide covers everything you need to know about hand pollinating and attracting natural pollinators to your abutilon patch for a bountiful harvest.

An Overview of Abutilon Plants

Abutilon, also called flowering maple or Indian mallow, encompasses a large group of tender perennial shrubs native to subtropical and tropical regions. They produce colorful, lantern-like flowers that gave rise to another common name – Chinese lanterns There are over 200 abutilon species, but only a handful have proven popular as ornamental garden plants

Several species, including A. megapotamicum and A. esculentum bear edible flowers and seed pods when pollinated. The fruit can be eaten raw or cooked and adds a mild, slightly mucilaginous texture. Home gardeners mainly grow abutilon for ornamental purposes, but with proper pollination, you can enjoy both beautiful blooms and tasty fruit.

How Abutilon Plants Are Pollinated

Abutilon feature hermaphrodite flowers containing both male stamens and female pistils. This makes pollination and fruit set easy since each flower can potentially self-pollinate. However, abutilon plants generally benefit from cross-pollination between different blooms thanks to insect activity.

Bees, hoverflies, beetles, butterflies and hummingbirds will frequently visit abutilon flowers to feed on nectar. As they move between blossoms, these pollinators transfer sticky grains of pollen from the stamens to the pistils. The pollen fertilizes the ovules contained within the flower’s ovary.

Once pollinated, the ovary swells into the edible seed pod while the rest of the flower parts fade away. The ripening fruit matures around 6-8 weeks after pollination occurs under optimal summer conditions. Time from pollination to harvest is longer in spring and fall.

Pollinating Abutilon by Hand

You can take pollination into your own hands to ensure adequate fruit set if natural pollinator activity seems lacking. Hand pollinating abutilon flowers is a straightforward process:

• Wait until flowers fully open, then remove the petals to expose stamens and pistil.

• Use a small brush or cotton swab to collect pollen from ripe stamens.

• Gently dab the pollen-coated brush onto the stigma (tip) of the pistil on another flower.

• Repeat this pollen transfer between several blossoms for best results.

• Replace petals after hand pollinating if desired. Mark pollinated flowers with twist-ties.

Perform hand pollination in the morning when pollen is most viable. Focus efforts on unpollinated flowers less than 2 days old for highest success rates.

Attracting Natural Pollinators

Encouraging pollinating insects and birds in your garden ensures abutilon flowers get routinely fertilized for steady fruit production. Here are some tips to attract pollinators:

• Plant a diversity of flowering plants that bloom at different times to supply food year-round. Native wildflowers specially evolved alongside local pollinator species.

• Include plants like asters, salvias, daisies, cosmos, sunflowers, bee balm, and sages that attract a variety of pollinating insects.

• Plant tubular flowers rich in nectar preferred by hummingbirds like fuchsias, columbine, honeysuckle, and native penstemons.

• Avoid pesticides which harm beneficial pollinating insects. Never spray open flowers.

• Supply clean water in a shallow dish, bowl, or bird bath for pollinators to drink and bathe. Add half-submerged stones for perching butterflies.

• Install nesting boxes for solitary bees or leave areas of bare soil and dried plant stems for ground-nesting species.

• Allow fallen leaves, dry grass, and small brush piles to provide overwintering sites for hibernating pollinators.

With abundant food and shelter in your garden, pollinators will flock to your abutilon and make quick work of pollinating the flowers.

Getting the Timing Right

Abutilon grow best in warm conditions above 60°F and may stop flowering in extreme summer heat or frost. For optimal pollination and fruiting, time your planting so that plants are established and blooming during ideal pollinator activity.

• In hot climates, grow abutilon as spring-fall annuals or succession plant for continuous harvests.

• Cool-season growers can target late summer blooms by starting plants indoors 8-10 weeks before the last frost date. Site containers in full sun or under row covers/cold frames for early maturity.

• Stagger planting dates 2-3 weeks apart to ensure overlapping bloom. Direct sow seeds or set out transplants.

• Overwinter potted abutilon indoors until spring when pollinators reemerge. Prune back plants before moving outside.

Proper timing maximizes pollination potential for your abutilon patch.

Caring for Pollinated Plants

Once your abutilon flowers have been successfully pollinated, a little special care will help developing fruit reach maturity:

• Water regularly as fruit swell, but avoid wetting foliage which can promote disease. Drip irrigation is ideal for delivering water right to roots.

• Install plant supports for heavily bearing varieties. Staking prevents branches from breaking under the weight of fruits.

• Prune back rampant growth if needed to improve air circulation and light penetration for high-quality fruit. However, avoid heavy pruning during fruit set.

• Apply a balanced liquid fertilizer every 2-3 weeks to provide nutrients for maturing pods. Fish emulsion or compost tea make good organic options.

• Monitor for pests and diseases. Aphids, whiteflies and cabbage loopers may need to be controlled to prevent crop losses.

With attentive care, your hand-pollinated abutilon plants will reward you with a bountiful harvest!

Troubleshooting Poor Fruit Set

Sometimes, even diligent hand pollination efforts result in flowers falling off or poor fruit development. Common causes include:

• Cool temperatures – Abutilon prefers warm conditions. Prolonged cool weather inhibits fertilization and causes flower drop. Boost temperatures with cloches.

• Low humidity – Dry air prevents pollen viability and frustrates pollinators. Increase humidity around plants by misting foliage daily.

• Inadequate sunlight – Weak, leggy growth reduces flowering and fruit set. Site plants for maximum sunlight.

• Over-fertilization – Excess nitrogen from fertilizer causes lush foliage at the expense of flower and fruit production. Reduce feeding.

• Water stress – Too much or too little water disrupts pollination and causes flowers or fruits to abort. Maintain even moisture.

• Age of plant – Old, overgrown abutilon plants have lower fruiting potential. Rejuvenate or replace aging specimens.

Adjusting growing conditions and plant care can often solve poor fruiting issues with abutilon.

Enjoying the Rewards

With proper pollination care, your abutilon plants will reward your efforts by producing an abundance of their versatile fruit. Harvest abutilon seed pods when they turn yellow-brown and begin to crack open. The edible seeds and surrounding tender flesh can be eaten raw, stir-fried, added to soups, or pickled for a tasty, nutritious treat.

Beyond the fruit, hand pollinating your flowering maple maximizes its ornamental display for double the visual impact in your garden. Share the fruits of your labors with friends and neighbors to spread the joys of growing abutilon.

Frequently Asked Questions About Pollinating Abutilon

What time of day is best for pollinating abutilon?

Perform hand pollination in the morning when pollen is freshest. Pollinating from mid-morning to noon aligns well with peak activity periods for many pollinating insects.

How long do abutilon flowers last?

Individual abutilon blooms remain open and viable for pollination for 1-3 days. Choose flowers that have newly opened to maximize chances of successful fruit set.

What’s the best way to collect abutilon pollen?

Use a small paintbrush, cotton swab, or specialty pollination stick to gather pollen from ripe abutilon stamens. Transfer the pollen by dabbing onto flower pistils to pollinate.

How many times should each abutilon flower be pollinated?

Pollinating each bloom 2-3 times on successive days helps ensure adequate pollen transfer and fruit development. Mark flowers after hand pollinating.
