10 Best Tools for a Windowsill Herb Garden

A little while back I shared 10 Easy Herbs Anyone Can Grow at Home, and the truth is, herbs really are as forgiving as I made them sound. You don’t need special equipment to keep a pot of basil or rosemary alive.

Over the years I have collected a handful of small, inexpensive tools that remove the guesswork. They mean less wondering whether you’re over-watering, less squinting at unlabeled seedlings, and a lot less waste. None of them are essential. All of them make the whole thing easier and a bit more enjoyable.

Here are the ten I’d actually recommend, and a note on which ones I’d call “must-have” versus “nice to have.”

Quick Reference

Tool	What it solves	Must-have or nice-to-have?
Self-watering planters	Over/under-watering	Nice-to-have
Good potting mix	Drainage, root health	Must-have
Herb scissors	Clean, easy harvesting	Must-have
Pruning snips	Woody stems (rosemary, sage)	Nice-to-have
Plant labels	Mixing up seedlings	Nice-to-have
Narrow-spout watering can	Splashing, precision	Nice-to-have
Small grow light	Low light / winter growing	Nice-to-have
Liquid or slow-release fertiliser	Feeding potted herbs	Must-have
Moisture meter	Watering guesswork	Nice-to-have
Drying rack or hanging bunches	Using up a big harvest	Nice-to-have

1. Self-watering planters

If you’ve ever come home from a few days away to a very sad, droopy basil plant, you’ll understand why these are worth it. A self-watering planter has a small reservoir at the base that wicks moisture up as the soil dries out, so the plant takes what it needs instead of you guessing.

Tip: They’re especially good for herbs like basil and parsley that hate drying out completely, and a genuine help if you travel or simply forget to check pots daily.

Each of these rectangular planters features a visible water level window. Made from high-quality, non-toxic plastic, they are scratch, abrasion, and impact-resistant.

2. A proper potting mix

This one sounds obvious, but it’s the difference-maker most people skip. Regular garden soil compacts in a pot and holds too much water around the roots, which is exactly what herbs like rosemary, thyme and sage don’t want.

Tip: Look for a mix labeled for pots or containers rather than garden beds. It’s lighter and drains faster, which matters more than almost anything else on this list.

3. Herb or kitchen scissors

I mentioned these briefly in the herb post, but they deserve a proper spot here because they’re genuinely the tool I reach for most. A pair of small, sharp scissors gives you a clean cut on soft stems like basil, parsley, chives and coriander, which helps the plant heal and regrow faster than tearing leaves off by hand.

Tip: Keep a pair in the kitchen drawer, not the shed. You’re far more likely to snip fresh herbs mid-recipe if they’re within reach.

These multi-purpose kitchen shears are dishwasher safe and cut through meat, poultry, vegetables as well as herbs.

4. Small pruning snips for woody herbs

Scissors are fine for soft stems, but woody herbs like rosemary and sage have tougher growth that benefits from a proper pair of snips. I still use the same pair of Fiskars Micro-Tip Pruning Snips I mentioned back in the herb post – small, sharp, and precise enough to trim without damaging the rest of the plant.

Tip: A clean cut just above a leaf node encourages bushier growth rather than one long, woody st

5. Plant labels

It sounds unnecessary until you’ve got six unlabelled seedlings that all look identical for the first few weeks. A cheap set of plant labels saves you from guessing which pot is basil and which is coriander.

Tip: You don’t need anything fancy. Even icy-pole sticks and a permanent marker do the job. Bought labels are just tidier if your windowsill doubles as a kitchen bench.

These plastic labels which I use are big enough to write plant name and planting date. If you want something a bit more attractive, these wooden labels with stainless steel stakes are very cute.

6. A narrow-spout watering can

A regular watering can is fine outdoors, but on a windowsill or kitchen bench, a wide spout tends to wash soil out of the pot or splash onto the bench. A small can with a narrow spout lets you water gently and precisely, right at the base of the plant.

Tip: It’s a small thing, but it’s the difference between a tidy windowsill and constantly wiping up soil and water marks.

This 1.0 litre (33 oz) watering can would be a stylish addition to any kitchen bench.

7. A small grow light

This is the one that surprises people. If your kitchen doesn’t get much direct sun or you want herbs going through winter, a small clip-on or stand-alone grow light can keep basil and parsley producing year-round instead of going leggy and pale.

Tip: You don’t need a serious setup. A small LED grow light on a timer for a few hours a day is enough to make a real difference to a windowsill that only gets indirect light.

This Canagraow light is height adjustable and has an auto on/off timer.

8. Liquid or slow-release fertilizer

Herbs in pots use up nutrients in the soil much faster than herbs in the ground, simply because there’s less soil to draw from. A regular feed keeps them productive rather than slowly running out of steam.

Tip: Little and often is the rule. Aliquid fertilizer every 2–4 weeks, or a slow-release one applied per the label. Over-fertilising can actually mute the flavor of some herbs, so more isn’t better here.

Scotts Pour + Feed fertilizer is boosted with trace elements that are vital to plant growth. If you prefer granules, try their Osmocote controlled release fertilizer.

9. A simple moisture meter

If you’re someone who either forgets to water or waters a little too enthusiastically, a cheap moisture meter takes the guesswork out completely. You push it into the soil and it tells you whether the plant actually needs water, rather than you guessing from how the surface looks.

Tip: Particularly handy for rosemary, thyme and sage, which would much rather be slightly dry than sitting in damp soil.

This meter has a long probe making it also useful for outdoors.

10. A drying rack or hanging bunches

Herbs have a habit of producing more than you can use all at once, especially in the middle of a growing season. Rather than letting a big harvest go to waste, a small drying rack (or simply tying stems into bunches and hanging them somewhere airy) lets you dry herbs for later use.

Tip: This works especially well for woody herbs like rosemary, thyme and oregano, which dry beautifully and keep their flavour for months in a jar.

Zippered mesh drying racks keep the bugs off.

What you actually need vs. what’s nice to have.

If you’re just starting out, don’t feel like you need all ten of these at once. A decent potting mix, a pair of scissors, and a simple fertilizer will get you further than any gadget on this list. Everything else – the grow light, the moisture meter, the self-watering planters — are things you add later, once you know which herbs you love growing and where your windowsill’s limits are.

That’s really the theme of growing herbs at home: start small, and only add what actually solves a problem you’re having.
