Which edge-mounting pins and anchors should you choose? Learn about the types and differences.

Sta­ble lawn bound­aries, flowerbeds, or grav­el paths require prop­er­ly secur­ing the edg­ing to the ground. The choice of mount­ing hard­ware depends direct­ly on the type and hard­ness of the soil, the sur­face’s load, and the spe­cif­ic pro­file being installed. Long plas­tic spikes work best for soft soil, while steel nails and rein­forced pro­files are essen­tial for rocky or clay soil. Read this guide to learn how to pre­vent edg­ing from shift­ing in win­ter and choose acces­sories tai­lored to your gar­den!

How to attach plastic edging in the garden?

The sta­bil­i­ty of gar­den edges depends on what you attach them with. plas­tic edges in a giv­en area. Stan­dard plas­tic strips have fac­to­ry-made holes for mount­ing hard­ware. The main pur­pose of the mount­ing hard­ware is to pre­vent the curb from bend­ing under the pres­sure of the mow­er and to pre­vent it from slip­ping out due to frost move­ment in the soil.

Depend­ing on the sub­strate, three main groups of prod­ucts are used:

• plas­tic fas­ten­ers (PP/PE) – resis­tant to mois­ture and chem­i­cals in the soil. Ide­al for stan­dard home gar­dens;
• met­al (steel) fas­ten­ers – ensure easy appli­ca­tion in com­pact­ed soil, clay and ground with crushed stone;
• pro­filed anchors (G‑PIN, W‑PIN) – spe­cial­ized mount­ing grids with increased trans­verse stiff­ness.

When choos­ing prod­ucts for instal­la­tion at Samm­ler, it’s impor­tant to con­sid­er the anchor­age depth. The sandi­er the soil, the longer the ele­ments should be to ensure the edge remains sta­ble.

Garden anchors – what are they for and how do they work in the soil?

The pri­ma­ry func­tion of gar­den anchors is to trans­fer hor­i­zon­tal and ver­ti­cal forces to deep­er lay­ers of the soil. When form­ing arch­es, cir­cles around trees, or straight lines, the anchors main­tain the desired shape of the plas­tic tape until the bark, grav­el, or grass back­fill is com­pact­ed.

A prop­er­ly installed anchor acts as an expan­sion anchor. Its pro­tru­sions and ser­ra­tions absorb the impact of pedes­tri­ans or light gar­den­ing equip­ment. Addi­tion­al­ly, these ele­ments pro­tect the geo­t­ex­tile and agro­tex­tile from being blown away by the wind, pre­vent­ing weeds from grow­ing along the bound­ary zones.

Edging pins – what lengths and materials work best?

When decid­ing on a pur­chase, it’s impor­tant to con­sid­er which edge pins will be appro­pri­ate for your spe­cif­ic plot. Typ­i­cal lengths range from 16 cm to 25 cm.

• 16–18 cm – suf­fi­cient for com­pact clay and black earth soils, where soil resis­tance is high,
• 24–25 cm – essen­tial in sandy, fresh­ly fer­til­ized or loose soil.

The dura­bil­i­ty of the plas­tic fas­ten­ers comes from the use of recy­cled polypropy­lene enriched with UV sta­bi­liz­ers. This pre­vents the mate­r­i­al from becom­ing brit­tle in low tem­per­a­tures and sun­light. Gal­va­nized or untreat­ed steel pins are suit­able for appli­ca­tions where the mate­r­i­al might bend when ham­mered.

Which edge anchors should I choose for difficult and rocky ground?

Which edge anchors will per­form with­out break­ing when the prop­er­ty is over­flow­ing with roots, rocks, or con­struc­tion debris? In such con­di­tions, tra­di­tion­al plas­tic ele­ments can deform when dri­ven in.

Steel nails or met­al anchors with a round or cross pro­file are a solu­tion for dif­fi­cult ter­rain. Dri­ving the steel pins is easy, and the ele­ment cuts through small obsta­cles in the ground. If you plan to work on dif­fi­cult ground, Samm­ler offers a wide selec­tion of durable fas­ten­ers that facil­i­tate pre­cise curb align­ment.

G‑PIN or W‑PIN – what is the difference between these anchors?

When choos­ing spe­cial­ized pins for gar­den edg­ing, it’s worth under­stand­ing the char­ac­ter­is­tics of pro­filed fas­ten­ers. In the case of solu­tions such as G‑PIN and W‑PIN, the dif­fer­ence comes down to cross-sec­tion and appli­ca­tion.

• G‑PIN It has a G‑shaped pro­file. This ensures high lon­gi­tu­di­nal stiff­ness and pre­vents the attach­ment from bend­ing when dri­ven into hard ground. G‑PIN is ide­al for sta­bi­liz­ing thick­er edg­ing or gar­den mats.
• W‑PIN It fea­tures a cor­ru­gat­ed cross-sec­tion resem­bling the let­ter W. This design increas­es the con­tact sur­face with the soil, which trans­lates into greater resis­tance to pull-out. This is a solu­tion for loose soils and for secur­ing areas sub­ject to high pull-out forces.

Design dif­fer­ences deter­mine effec­tive­ness in a giv­en type of soil, so it is worth deter­min­ing the degree of soil com­paction before pur­chas­ing.
