How to maintain your network: garden it, don't harvest it

Maintaining a network means treating it like a garden: regular small care while nothing is wrong, so that something is alive when you need it. The alternative — ignoring it until a job search or a funding round sends you out with a basket — is harvesting from soil nobody watered.

You can feel the difference from the receiving end. There’s the former colleague who pings you twice a year with something genuinely interesting, and there’s the one whose name appearing in your inbox means a favor is coming. One of these people you’d take a call from at 9pm. The maintenance, or its absence, is the relationship.

The good news is that tending is cheap. Nobody’s network garden needs daily watering — it needs a light weekly habit, a seasonal routine, and the willingness to prune.

Tending beats harvesting — and the difference is timing

Every relationship you don’t touch is slowly cooling. Not dramatically; there’s no falling-out, no unfriending. The shared context just ages out — they change jobs, you change cities, and after two silent years the relationship has moved from warm to technically still exists. This decay is the default state of a network, the way weeds are the default state of a garden.

Harvest-mode networking ignores the decay until the day it can’t: the layoff, the fundraise, the search for a co-founder. Then it discovers that activating a cold network is slow precisely when speed matters most. The research backs the long game — Wolff & Moser (2009) tracked employees over three years and found networking behavior predicted both current salary and salary growth, an effect that compounds quietly across a career.

The gardening stance flips the timing: invest small amounts continuously, harvest as a side effect. What that looks like in practice is network maintenance as a routine — most of it modest to the point of being boring, which is exactly why it works.

Dormant ties: the best plot you’re not planting

Here’s the most counterintuitive finding in the field. Levin, Walter & Murnighan (2011) asked executives to reconnect with dormant ties — relationships that were once active but had lapsed for years — and seek advice. The reconnected contacts provided advice rated more novel than what the executives’ active ties offered, and the old trust was still substantially intact. Old relationships had quietly accumulated new worlds: new roles, new industries, new people.

That makes dormant ties the rare asset that appreciates while ignored. The acquaintance from your old team now runs data at a company you’ll never otherwise touch. The trust you built sharing an office for two years didn’t expire — it’s just unused. And unlike new contacts, reviving these costs no introductions, no small talk from zero, no proving yourself: the relationship resumes mid-sentence.

Most people never collect this yield because reactivation feels awkward. It mostly isn’t — receivers welcome these messages far more than senders predict (Sandstrom & Boothby, 2021) — and the reconnect message generator can take the blank-page problem off your hands. Two revivals a quarter is enough to keep the dormant plot producing.

The seasonal maintenance routine

The weekly touch habit — fifteen minutes, two or three messages to whoever’s due — is covered in our guide to keeping in touch with professional contacts. What that habit can’t do is structural work. The weekly slot keeps individual plants alive; it never steps back and looks at the whole plot. Left to weekly logic alone, a network drifts — the list ages, the wrong people absorb the touches, and the dormant beds never get visited.

So once a quarter, give the garden an hour. The five passes below fit comfortably in sixty minutes once the list exists, and they’re the difference between maintaining a network and merely messaging one.

1. Walk the beds: review the list

   Open your networking tracker and read the whole active list. Who changed jobs? Whose situation moved? Who did you mark important in January that hasn’t crossed your mind since? This pass updates the map before you act on it.

2. Water what matters: a give-first pass

   For the 10–15 relationships you most want alive, send or queue one give-first touch each: a relevant link, a specific congratulations, an introduction. No asks in this pass — this is watering, not picking.

3. Revive two perennials: dormant ties

   Pick two lapsed relationships you’d genuinely like back and send each a short, trigger-led note. Two per quarter is eight a year — enough to compound, few enough to stay sincere.

4. Prune: move the inactive out of the active

   Anyone you’ve touched three times with no signal back, anyone whose relevance has genuinely lapsed: out of the active list, into the archive. Not deleted — demoted. The energy they were consuming flows back to the beds that grow.

5. Plant one new bed

   One forward-looking addition per season: a community joined, an introduction requested, a person from the edge of your world moved deliberately into it. Gardens that only preserve eventually just shrink.

Give first, ask seldom

The watering in this metaphor has a precise composition: most touches should carry value toward the other person and request nothing back. Adam Grant’s Give and Take (2013) made the empirical case that habitual givers build the strongest networks over the long run; extraction, meanwhile, is remembered with unfair clarity. People forget your title. They remember whether your name in their inbox historically meant a gift or an invoice.

Give-first material is humbler than it sounds — you don’t need favors to dispense or jobs to offer. You need attention: the article that maps to their problem, the two contacts who should know each other, the question that takes their expertise seriously, the specific compliment on work they actually did. A working specimen: “Your old teammate Jonas is moving into healthcare data — you two should compare notes; want an intro?” Eleven seconds to read, genuinely useful, asks nothing. Our piece on authentic networking covers the stance in full; the maintenance-specific point is that give-first touches are easier to send regularly, because nothing about them needs courage.

And when you do need to ask — for the referral, the intro, the advice — ask plainly. A garden is allowed to feed you. That was the point of planting it.

Pruning is care, not betrayal

The step everyone resists. Your active list has people on it from inertia: the contact who never once replied, the industry peer whose field you left, the name you keep only because removing it feels rude. Every one of them silently taxes the list — they pad the weekly review, blur your sense of who matters, and turn maintenance into a chore that eventually gets skipped.

The reluctance usually dresses itself up as optimism — you never know, this contact might matter someday. True, and the archive handles that case perfectly: nothing in it is lost, everything in it is findable, and none of it demands weekly attention.

So prune seasonally, and prune kindly. Demotion, not deletion: out of the active tiers, into the archive, where they cost nothing and remain findable. Some of today’s prunings become tomorrow’s valuable dormant ties — that’s the system working, not failing. The bar for staying active is simple: would I honestly invest one touch in this relationship this quarter? If the answer keeps being no, the answer is the answer.

The part a tool can carry

Everything above runs on paper until scale breaks it. Somewhere past fifty actively maintained relationships, the bookkeeping — who’s due, what did we last talk about, which quarter did I last prune — starts eating the time that should go to people. That bookkeeping is the part worth delegating: Endearist keeps the tiers, last-contact dates, and notes in a local file on your machine and surfaces who needs water this week, which leaves you the only part that ever mattered — writing the message. Whether you use a CRM or a spreadsheet, the garden doesn’t care. It only cares that someone shows up, briefly, every season.
