Spring Pasture Prep Checklist: How to Maximize Growth Before First Cut

Walk the field before you do anything else

As soon as the ground will take a boot without making a mess, walk it. You are looking for winter damage, bare spots, compacted gates and feeders, low wet areas, leftover manure piles, broken fence, and irrigation problems you will not see from the driveway. Take notes. The temptation is to start fertilizing or turning horses out because the first green is up. The better habit is to fix the structure of the field first.

If winter turned a corner of the pasture into a sacrifice paddock of mud, plan how you will keep horses off that spot until it recovers. Churned, compacted ground in March becomes a weed patch in June.

Fertility: feed the field on purpose

A soil test beats a guess. If you have never tested, or have not tested in a few years, spring is a good time to pull samples and find out whether you need lime, nitrogen, or other nutrients — and whether you have been adding things you already have enough of. Local extension advice is worth more here than a generic bag rate copied from the internet.

If you do fertilize, time it for when the grass can use it, and keep horses off according to the product instructions and your own common sense. The goal is a stronger stand for grazing or for a first cutting, not a flush of growth you immediately trample or a nutrient runoff problem after a rain.

Spread leftover manure instead of leaving winter piles in place, but do it in a way that does not smother grass or create rough, uncuttable clumps in a hay field. Hay fields and horse pastures have slightly different rules; be honest about which one you are managing.

Irrigation and sprinklers: fix them before you need them

In irrigated country around Pasco and the Columbia Basin, water is not an afterthought. Spring is when you find the broken risers, plugged nozzles, leaking lines, and badly aligned sprinklers — not the first 90-degree week. Run the system, walk it while it is on, and repair what you find. A dry corner in April becomes a weak, weedy corner in the first cutting.

If you share a water schedule or have limited turns, plan those dates now. Pasture and hay that start the season even, and watered on time, are easier to keep even. If you also think about later cuttings, this is the moment to get the system ready so mid-summer irrigation is not a scavenger hunt for parts.

Weeds: get ahead of them while they are small

Spring weeds are easier to deal with than a June jungle. Identify what you actually have. Some “weeds” are just winter annuals that will fade when grass takes off; others will take the field if you ignore them. Options range from mowing or hand-pulling on a small place, to a carefully chosen herbicide on a larger field, used according to the label and with livestock withdrawal times in mind.

Do not turn horses onto a pasture you have just treated until it is safe to do so. If you are putting the field up for hay, remember that what you spray or spread can end up in a bale. When in doubt, get local advice before you treat a field that will feed horses.

Seeding, rest, and turnout

Bare spots can be overseeded in spring on many grasses, but only if you can keep animals off long enough for seedlings to establish. Broadcasting seed into a pasture you immediately turn horses back onto is how you feed seed to birds. A temporary fence around a weak area is often worth more than an extra bag of seed.

Resist early turnout on wet ground. The grass may look inviting; the hoof prints will still be there when you wish you had a cleaner first growth. Use a sacrifice area or a dry lot and hay — which you hopefully stored well last fall — until the field can take the traffic.

If you plan to cut hay

Think now about how you will cut, cure, and store a first cutting: equipment, help, and a dry place for bales. A beautiful stand does not help if the hay comes off the field and sits on dirt in a rain. Our hay storage guide and cuttings guide are useful even if you only put up a little hay and buy the rest.

If you do not put up your own hay, spring is still a good time to talk to a local supplier about what they are growing and when first cutting might start showing up. Planning beats a surprised phone call in June.

A simple spring weekend plan

If you only have a couple of days, do them in this order: walk and note problems, repair irrigation and obvious hazards, keep animals off the wettest ground, then deal with fertility and weeds once you know what the field needs. A messy attempt to do everything at once, with horses still on the pasture, is how spring prep turns into a half-finished list and a new set of hoof prints. Two focused days in the right order will beat a month of good intentions.

Frequently asked questions

When should I start spring pasture prep in our area?

As soon as you can walk the field without tearing it up, and early enough to fix irrigation before the first real heat. The calendar varies by year; the field will tell you when it is workable.

Can I skip a soil test if I fertilized last year?

You can, but you are guessing. A test every few years, or after a disappointing stand, keeps you from spending money in the wrong place or missing a lime need that fertilizer will not fix.

My horses will wreck the pasture if I keep them off. What do I do?

Feed hay in a dry lot or sacrifice area until the pasture is ready. That is exactly what the winter hay stack is for. Turning out early to “save hay” often costs you pasture for the rest of the spring.

I don’t grow hay, I only have a horse pasture. Is this still for me?

Yes. Fertility, weeds, wet-gate compaction, and turnout timing are horse-pasture issues. Use the parts of the checklist that fit a paddock, and skip the cutting-equipment notes.

And if you need hay while the pasture catches up, contact Ohana Farms or see what we have in The Hay Barn — including timothy, orchard grass, and alfalfa. We are glad to help you cover the gap until your own grass is ready for the horses again.
