The Seed Starter Trays I Use to Grow Mulberry Trees From Seed

If you’ve ever tried growing mulberry trees from seed, you already know the frustration. Germination rates can be painfully low, and moisture control is everything. Last spring, I lost two full batches of stratified mulberry seeds simply because my old flimsy trays dried out too fast. That failure pushed me deep into researching better seed starter trays for mulberry growing — and eventually led me to the SOLIGT Self Watering Seed Starter Trays with Humidity Domes. They’ve genuinely changed how I start my seedlings.

Mulberry seeds are finicky. They need consistent moisture, warmth, and humidity — especially right after stratification when they’re primed to sprout. Even a few hours of drying out can kill a seed that’s just beginning to crack open. I needed a system that could babysit moisture levels without me hovering over the trays every few hours.

After my spring losses, I decided enough was enough. I wanted trays built with intention — not the cheapest dollar-store plastic that cracks by week two. Here’s exactly what happened when I switched.

The Self-Watering Trays That Finally Stopped My Mulberry Seeds From Drying Out Mid-Germination

Mulberry seeds are notoriously fussy about moisture consistency during germination—too dry for even a day or two and you’ve lost them. After my two failed batches last spring, I needed a tray system that would actually maintain moisture without daily babysitting.

What works

• The self-watering bottom wicking system keeps soil moisture steady for 3-4 days without checking the water reservoir, which means I can trust the trays through unpredictable spring weather swings.
• The humidity dome actually stays sealed tight—my germination rates jumped from 30% to 75% on stratified mulberry seeds because condensation stays trapped instead of evaporating into thin air.
• The thick plastic doesn’t warp or crack after one season of heat cycles and sunlight, unlike my old flimsy trays that became brittle by mid-summer.

What doesn’t

• The water reservoir fills from the bottom, which is great until you overwater and get algae blooming in the water chamber—now I have to drain and refill more often than I’d like during humid summers.
• At 72 cells per tray, seedlings touch each other fast, so you have maybe 4-5 weeks before root competition becomes a real issue and you need to pot them up or thin them out.

I did hesitate when I first filled the reservoir—I was paranoid I’d replicate my drying-out disaster by overfilling and suffocating the seeds instead—but the design actually has enough margin for error that one learning curve and you’ve got it dialed in. If you’re tired of losing mulberry seeds to moisture swings, grab the SOLIGT Self Watering Seed Starter Trays with Humidity Domes, Extra Thick Plastic Seed Starter kit — 3 Pack 72 Cells.
