Horse Paddock Care in May: A Practical Spring Checklist

May is often the point when a horse paddock changes gear. Longer days and warmer soil can turn slow spring growth into a surplus within a surprisingly short time.

The aim is not simply to grow as much grass as possible. Good May management keeps useful grass leafy, gives worn areas a chance to recover and avoids creating more grazing than a horse can safely use. A weekly field walk is usually more valuable than following a fixed calendar, because soil, weather, stocking density and individual horses all change what the paddock needs.

Start with a weekly paddock walk

Walk the whole field rather than judging it from the gate. Look at both the grass and the way the horses are using it:

• Are some areas being grazed very short while others are becoming tall and stemmy?
• Are gateways, troughs or favourite tracks becoming bare or compacted?
• Have earlier repairs established evenly, or are there still thin patches?
• Are docks, thistles, ragwort or other unwanted plants beginning to appear?
• Is the soil moist enough for seed or fertiliser to be useful?

Taking a few photographs from the same points each week makes changes easier to spot. It also helps distinguish a short-lived flush after rain from sustained growth that needs a change in grazing management.

Balance grazing with recovery

Fast growth does not automatically mean unrestricted turnout will suit every horse. Good doers, native types and horses with a history of laminitis may need carefully controlled access even when the field looks ideal. Monitor body condition, crests, hoof comfort and the amount of grass actually being eaten. Our guide to laminitis risk and changing grass explains the wider horse-health considerations.

Where space allows, divide the field so one section can rest while another is grazed. Temporary electric fencing can make rotation or strip grazing more practical, provided the fence is correctly installed, clearly visible and suited to the horses using it.

Avoid allowing every section to be grazed down to bare soil. Grass needs enough leaf to keep growing, and exposed ground is more vulnerable to weeds, compaction and summer drought. Equally, leaving the whole paddock untouched can allow mature stems and seedheads to replace the softer leafy growth horses tend to select.

Use a harrow for a clear reason

Harrowing can break up dead material, level minor surface disturbance and open a dense mat so light and air reach the base of the sward. It should not be an automatic May job, however. Ground that is too wet can be damaged by machinery, while harrowing horse droppings in cool or damp conditions may spread parasite larvae across a wider grazing area.

Continue regular poo-picking and fit any harrowing into a considered parasite-control and resting plan. If manure is to be spread, horses should be removed and the timing, weather and rest period should be appropriate. Ask your vet, suitably qualified parasite adviser or paddock contractor if you are unsure.

Repair thin areas while moisture remains

Early May can still offer a useful opportunity to overseed small bare or sparse patches before the soil dries. Seed needs good contact with the soil, consistent moisture and protection from grazing and traffic while it establishes. Simply scattering seed into long grass or returning horses immediately is unlikely to produce an even repair.

• Identify why the patch became bare before reseeding it.
• Relieve severe compaction or drainage problems where necessary.
• Choose a seed mixture intended for horse paddocks and the conditions on the site.
• Keep horses off the repaired area until the new plants are well rooted.

Keep weeds from gaining space

A thick, healthy sward is one of the best long-term defences against weeds, because it leaves less bare soil for unwanted plants to colonise. Deal with isolated weeds before they flower and set seed, but identify the plant before choosing a control method. Digging, repeated cutting and herbicide treatment are not interchangeable, and established perennial roots may require a longer-term plan.

Remove poisonous plants safely and keep all pulled or cut material away from horses and forage. If using a herbicide, select one approved for the situation, follow the label exactly and observe every grazing exclusion period.

Does the paddock need Suregrow fertiliser?

May grass can use nutrients quickly, but visible growth alone does not prove that more fertiliser is needed. Soil pH, nutrient status, drainage, compaction and grazing pressure all affect performance. A soil test is the best starting point where the cause of poor growth is unclear.

Suregrow Fertiliser is a slow-release product formulated for horse and pony paddocks. It supplies nitrogen, phosphorus and sulphur to support sustained grass growth, root development and a denser sward. The manufacturer's current spring and summer guidance is four to five 20kg bags per acre, applied from early March to late July.

Spread it as evenly as possible and follow the current bag label. Rainfall or heavy dew helps the pellets dissolve, so do not apply simply because it is May if the ground is dry and no useful moisture is expected. Fertiliser is also unlikely to solve a field that is being continually overgrazed or where soil pH is preventing efficient nutrient uptake.

Your May horse paddock checklist

• Walk the field weekly and photograph recurring problem areas.
• Adjust grazing before short patches become bare or tall areas turn coarse.
• Monitor horses closely as grass availability and quality change.
• Poo-pick regularly and use a harrow only as part of a suitable plan.
• Overseed small thin areas while moisture and resting time are available.
• Identify and control weeds before they set seed.
• Use soil information and current label instructions before applying fertiliser.
