Yarrow: A Perennial That Tin Handgrip Heat, Drought & Pitiable Soil

If you lot are sitting on our front end porch, you lot can't assistance but notice the industrious picayune ants scurrying across the flagstone walkway (Piper, our youngest Sheltie, finds them fascinating together with likes to poke at the tiny dark ants amongst his nose). There are genuinely 2 pismire colonies–one at the far halt of the pathway together with ane a picayune closer to the porch.

I prefer non to wage nation of war on the creatures amongst whom I part my garden, but this feeling of skillful volition was challenged a few summers dorsum when ane of my favourite phlox began to popular off mysteriously ane stalk at a time. Influenza A virus subtype H5N1 quick investigation revealed it was the ants together with their earth-moving ways. I reject to resort to pesticide, then I began to experiment amongst plants that mightiness alive inward harmony amongst the 2 good entrenched colonies.

Yarrow inward my garden.

That brings me to the primary dependent area of todays post–Yarrow. Yarrow was ane of the few plants that seemed to hold upwards the ant's constant excavations (sedum groundcovers are another). The Yarrow genuinely seems to appreciate the sudden drainage provided past times the sand soil the ants convey upwards to the surface.

Yarrow is a tough, drought tolerant perennial that likes a hot, dry, sunny location. Unlike then many perennials that similar rich fertile soil, Yarrow is quite happy in average to pathetic soil (provided at that spot is skillful drainage). If your garden soil is likewise rich, you lot may genuinely notice that your yarrow flops.

Full Sun is essential. Too much shade together with Yarrow tin move leggy.

Mid-summer Yarrow produces a profusion of round, apartment blooms that are composed of of tiny, daisy-like flowers. Colors include yellow, pink, cream, peach, terra cotta, ruby together with maroon.

Yarrow makes a great, long-lasting cutting flower. It's also a dandy everlasting bloom that tin live hung to dry. Simply cutting your flowers (morning is best) together with necktie them amongst a chip of twine. Hang them inward a cool, dry out house out of immediately sunlight until the flowers are dry out to the touch.

One in conclusion argue to grow Yarrow–bees together with butterflies dearest this flower!

Growing Yarrow from Seed

Plant Yarrow seeds indoors half-dozen to viii weeks earlier the in conclusion frost date. Sow seeds on the surface of moist potting soil together with gentle press down. Place the tray inward a warm, sunny place inward the house. Your seeds should germinate inward 2 to 3 weeks.

Myself, I prefer to purchase minor potted plants inward the spring. Yarrow may bloom that offset summer, but I notice it takes a total flavor to genuinely larn established.

Growing Yarrow

The nigh of import element inward existence successful amongst growing Yarrow is giving it the atmospheric condition it requires; total sun, skillful drainage together with average to pathetic soil. If your soil is heavy, add together to a greater extent than or less organic affair together with fifty-fifty to a greater extent than or less fine pebbles to better the drainage.

Water good until your yarrow is established. Once it has settled in, you'll notice Yarrow is real drought tolerant together with may alone require supplemental H2O during times of extreme drought.

Unlike nigh perennials, Yarrow doesn't require whatever fertilization.

Yarrow tin hold off rather tired afterward it flowers. I've found it's best to cutting the whole flora dorsum hard. It volition hold off awful for a span of weeks, but you'll live rewarded amongst fresh dark-green increment together with possibly fifty-fifty a minute even out of flowers inward belatedly summer/early fall.

Divide Yarrow every 3 to 5 years inward the early on jump or inward the fall.

Pests together with Diseases

Yarrow is pretty resistant to pests, but aphids tin occasionally live an issue. Influenza A virus subtype H5N1 skillful nail of H2O from the hose tin dislodge the aphids. If the work persists, you lot tin operate an insecticidal soap.

Powdery mildew together with rust tin also pose a problem. To eliminate the possibility of mildew, avoid watering the foliage, if possible, together with let for skillful air stream betwixt plants.
