You should not leave your soaker hose out in winter if temperatures drop below freezing in your area. Frozen water inside the porous walls will crack and split the hose material. A single hard freeze can ruin an entire hose that would have lasted years with proper care. Bringing it indoors before the first frost is worth the 20 minutes of effort.
I learned this lesson by losing a perfectly good 50-foot soaker hose. I left it buried under mulch one fall and forgot about it. When I pulled it out the following spring, a 6-inch section had split wide open where trapped water froze and tore through the rubber wall. The rest of the hose had smaller cracks that sprayed water sideways instead of seeping it into the soil. That one lazy decision cost me $20 and a trip to the garden center.
The technical reason comes down to how these hoses are built. Porous rubber and polyurethane soak up small amounts of water inside their walls. This happens even after you turn off the faucet. When temperatures drop below 32°F (0°C), that trapped water expands by about 9% as it turns to ice. The micro-pores that make the hose work so well during the summer become weak points in winter. Ice pushes outward from inside the walls, cracking the material and creating blowout spots that ruin even flow.
SDSU Extension says to drain all water before storing your hose. Keep it where rodents can't chew through the rubber. UNH Extension suggests storing hoses with valves open and one end cap off. This lets any trapped moisture escape during the off-season. Both sources agree that indoor storage keeps your hose working for three to five years instead of just one.
Here's how to winterize soaker hose systems in three quick steps. First, disconnect the hose from your supply line and remove the end cap. Second, lift the hose section by section starting at one end to drain all water out. Walk the full length and raise each portion above the next to push every last bit of moisture through. Third, coil the hose into a loose loop without sharp bends that could kink or crack the material.
For soaker hose storage, pick a spot indoors that stays above freezing and stays dry. A garage shelf, basement hook, or sealed plastic bin all work well. Keep the hose off the floor to prevent moisture from collecting underneath. If rodents are a concern in your garage or shed, a sealed bin with a lid stops mice from gnawing through the rubber during the winter months.
I now prep my soaker hoses every October. It takes less than 20 minutes for my entire garden. I walk the length of each hose, lift each section to drain it, and coil everything into a plastic bin in my garage. When spring comes, I pull the bin out and have my whole system ready to go in minutes. The hoses still look and perform like new after three seasons of this routine.
If you live in a mild climate where temperatures stay above freezing, you can leave your soaker hose outside year-round. But if you get even a few hard freezes each winter, bring it in. The risk isn't worth the $15 to $30 cost of a new hose. Check your USDA zone if you're not sure how cold your area gets.
Mark your calendar for two dates each year. Set a reminder to pull the hose in before your region's first frost date. Set another to put it back after your last frost in spring. This simple habit saves you money and keeps your soaker hose running strong for years to come.
