Fixing Morning Glory Failure: Soil Fertility and Phosphorus Needs

Morning glories need fertile, phosphorus-rich soil with neutral pH (7.0). Amend in spring with compost, aged manure, and peat. Supplement with a high-phosphorus water-soluble fertilizer like Miracle-Gro Bloom Booster for

Why Petunias Fail While Other Annuals Thrive: Disease Resistance and Care

If only petunias die in a thriving bed, soil isn’t the issue. Heirloom petunias are disease-prone; switch to hybrids like Celebrity or Wave series (available at Park Seed or garden centers). Prune monthly by one-third to

Troubleshooting New Petunia Plantings: Over-Fertilization, Drainage, and Watering

New petunias in window boxes with cocoa liners and Miracle-Gro soil (which already contains fertilizer) likely suffered from fertilizer burn when more slow-release pellets were added. Metal boxes must have drainage holes

Harvesting Zucchini: Optimal Size for Flavor and Creative Uses for Oversized Fruit

Pick zucchini at 4–7 inches for best texture and flavor. Very large ones (3+ inches diameter, 10+ inches long) can be hollowed and stuffed (sausage, peppers, breadcrumbs, tofu) or carved like pumpkins. But small is best

Reviving Straw Flowers with Deadheading: Timing and Technique

All flowering plants need deadheading to redirect energy from seed production to blooming. Cut your shabby straw flowers back by one-third. Within two weeks, side shoots and new blossoms should appear. Then deadhead regu

Rescuing Waterlogged Container Petunias: Drainage, Root Aeration, and Recovery

Excess rain waterlogs containers. First, ensure pots drain perfectly. Remove plants, air out roots (not bone-dry, just aerated) on paper towels. Pinch back stems 1–2 inches to stimulate fresh growth. Replant in fresh, we

Transplanting Mature Flowering Quince: Root Ball and Hole Preparation

Flowering quince is a suckering shrub—each stem is a potential plant, but separating them risks loss. Move as many stems as possible with a large root ball. Dig the new hole as deep as the root ball but twice as wide (e.

Fixing Shasta Daisy Decline: Water Management and Sun Requirements

Shasta daisies yellowing and blackening from the bottom up usually signal water issues: either frequent sprinkler drift (causing fungal problems) or insufficient deep watering (causing drought stress). Water deeply with

Fertilizing Wave Petunias: Frequency, Types, and Annual Nature

Fertilize Wave petunias every other week with liquid fertilizer (follow label, don’t over-concentrate). Water before fertilizing—never fertilize dry plants. Better yet, mix time-release fertilizer (e.g., Osmocote Plus) i

Treating Insect Damage on Petunias: Organic Solutions for Holes and Pods

Holes in petunia flowers and dry pods indicate insects—likely flea beetles, whiteflies, or aphids. The safest, cheapest control is insecticidal soap: buy ready-made or mix 1 tsp lemon liquid dish soap (non-concentrated)

Growing Purslane and Safe Weed Control in Flower Beds

Purslane (a portulaca) loves full sun. Water every 2–3 days until established, then it’s very drought-tolerant. Avoid frequent sprinkler hits—it prefers dry conditions. Flowers open only in daytime. Weed control: No spra

Encouraging Volunteer Impatiens: Self-Seeding Tips for Cold Climates

Impatiens are self-cleaning—they drop spent blooms, scattering seeds. Seeds need ~6 months of dormancy (longer if soil freezes). To encourage volunteers in Southern Indiana: don’t till the bed in fall or spring. Leave de

Controlling Caterpillars on Petunias and Restoring Blooms

Tiny black grains on petunia flowers and leaves are likely caterpillar frass (droppings). Insecticidal soap won’t work. Use Spinosad (organic, e.g., Captain Jack’s Deadbug Brew), spraying in the evening to protect bees.

Lichens on Dogwood: Harmless but Check for Other Tree Issues

The light green patches on your dogwood are likely lichens—harmless, slow-growing organisms that indicate clean air. They do not harm the tree. Your dogwood’s decline has another cause. Check Cornell’s Dogwood Factsheet

Overwintering Sweet Potato Vines: Simple Tuber Storage for Budget Gardeners

Yes, you can dig sweet potato tubers in Chicago and store them for spring. Follow the same method: dig with vines, dry, remove vines, wrap in newspaper, bag, and keep cool. Replant after frost or start early indoors. Thi

Overwintering Sweet Potato Vines: Tuber Storage for Next Season

Sweet potato vines don’t make good houseplants (whitefly magnet). Instead, dig tubers after frost, leave some vine attached, dry in a garage or shed, cut off vines, wrap tubers in newspaper, place in a paper bag, and sto

Identifying and Caring for Polka Dot Plant (Hypoestes phyllostachya)

Your plant with wrinkled leaf edges is a Polka Dot Plant (Hypoestes phyllostachya). It thrives in bright, indirect light—direct sun causes legginess. Wrinkled leaves indicate stress: uneven watering, wind exposure, or pe

Troubleshooting Non-Blooming Diamond Frost Euphorbia

Diamond Frost (Euphorbia) prefers hot, dry conditions. Let the soil dry between waterings (but not to wilting). Avoid wetting foliage, and never water with sun-heated hose water—it can fry buds. Provide full sun, includi

Snapdragon Frost Tolerance and Self-Seeding Habits

Snapdragons are hardy annuals: they survive light frost but perish in a hard freeze. The bonus? They self-sow readily. If you deadhead spent blooms throughout the season, the seed pods left on the ground will overwinter

Growing Mandevilla in Extreme Heat: Watering and Alternative Vines for Arizona

Mandevilla tolerates triple-digit heat but needs deep watering every 3–4 days in peak summer. “Deep” means a trickling hose for 45 minutes or a soaker hose/sprinkler for over an hour—not hand watering. Other heat-toleran
