How-to: Herbs — Rio Ranch

Fresh culinary herbs — Mediterranean & soft herbs Rosemary, thyme, oregano, and sage live for years on almost no water — the easiest, highest-value square footage in the whole garden.

01 Quick spec

Perennial

Mediterranean herbs return yearly

Low-water

Drought-tough once set

Year-round

Something to pick most months

North Texas window: set out perennial herbs in spring after the last frost (~April 1) or in fall to root before winter. Sow tender annuals like basil after frost; sow cilantro in the cool of fall and early spring — it bolts the moment summer heat arrives.

02 Growing it here

Mediterranean perennials

Rosemary, thyme, oregano, and sage are built for Zone 8 — hot sun, lean soil, and sharp drainage are exactly what they want. Plant from transplants 12–24 in apart, water to establish, then back way off; they rot in rich, wet ground. Most shrug off our mild winters and come back bigger each year.

Soft herbs by season

Basil loves the heat — direct-seed or transplant after frost and pinch often to keep it from flowering. Cilantro, dill, and parsley are cool-season here: grow them fall through spring and let them go in summer. Succession-sow cilantro every few weeks for a steady supply.

03 The year

Month	What happens
Feb – Mar	Sow/plant cool-season cilantro, parsley, dill; divide established perennials.
April	Set out perennials and sow basil after the last frost.
May – Sept	Mediterranean herbs and basil thrive; harvest steadily; cilantro bolts and rests.
Sept – Oct	Re-sow cilantro/parsley for fall; perennials get a second flush as heat eases.
Winter	Hardy perennials hold through mild cold; protect rosemary/basil in a hard freeze.

04 Problems & what to watch

Too much love

The #1 killer of Mediterranean herbs is overwatering and rich soil — it brings root rot. Plant lean, drain sharp, and let them dry between waterings. Crowding cuts airflow and invites powdery mildew, especially on sage and oregano.

Bolting & pests

Cilantro and basil bolt fast in heat — pinch flowers and succession-sow. Watch for aphids and spider mites in dry spells and caterpillars on parsley and dill (often swallowtail larvae — easy to relocate).

05 Harvest, storage & beginner mistakes

Step	How & how to keep
Harvest	Snip in the cool morning; take no more than a third at once. Regular cutting keeps plants bushy and productive.
Fresh / dry	Soft herbs keep ~1 week in water or a damp towel. Hang-dry woody Mediterranean herbs — they dry beautifully and store for months.
Preserve	Freeze basil/cilantro in oil cubes; dry oregano, thyme, sage, and rosemary for the pantry jar.

Beginner mistakes to skip: watering perennial herbs like vegetables (they want it dry); planting them in rich, soggy soil; trying to grow cilantro through the summer (it will only bolt); never harvesting (herbs need cutting to stay vigorous); and letting basil flower, which turns the leaves bitter — pinch it back.
