Growing resources

Perlite (large bag)

Mix into soil to improve drainage — dahlias hate wet feet.

Bone Meal Fertilizer

High-phosphorus feed for strong tuber development at planting time.

Low-Nitrogen Fertilizer

Too much nitrogen = all foliage, no blooms. This keeps the balance right.

Bamboo Stakes (6 ft)

Essential for dinner plates and tall varieties. Get taller than you think you need.

Plant Support Clips

Gentle on stems — clip dahlias to stakes without cutting into the stalk.

Heavy-Duty Tomato Cages

Works great for medium varieties that need all-around support.

Mesh Storage Bags

Breathable bags for storing tubers over winter — prevents rot.

Vermiculite

Pack tubers in this to maintain the right humidity during storage.

Stackable Storage Bins

Keep your labeled tuber bags organized in the basement or garage.

Garden Digging Fork

Far less likely to spear tubers than a spade when lifting clumps in fall.

Waterproof Plant Labels

Label every single tuber — you will thank yourself next spring.

Watering Wand

Water at the base without soaking foliage — reduces powdery mildew.

Slug & Snail Bait (pet-safe)

Young dahlia shoots are slug magnets. This iron phosphate formula is safe around pets.

Neem Oil Spray

Good all-rounder for aphids, spider mites, and early powdery mildew.
