Frequently Asked Questions


How do I manage powdery mildew on Apollo (120-day) plants?
Look for a white, dusty coating on Apollo leaves that starts in warm, dry spells and then spreads. Remove the most affected leaves early, then thin foliage for airflow and avoid overhead watering so leaf surfaces stay dry. Spray a labeled sulfur fungicide (or potassium bicarbonate) at the first sign and repeat according to the product label, especially during humid stretches.
How often should I water Apollo during the main growing phase (about weeks 4–10)?
During active vegetative growth, keep the soil consistently moist but not soggy—water enough to wet the root zone to about 6–8 inches, then wait until the top 1 inch of soil dries before watering again. In full sun, this often works out to roughly 1–2 deep waterings per week, but increase frequency during hot, windy weather and reduce if the soil stays wet or plants look droopy from overwatering.
How can I tell when Apollo is ready to harvest?
Apollo is ready when pods/fruit are fully developed for the variety size, the surface color matches the expected ripe stage, and the plant has largely finished pushing new growth. Harvest in the morning once ripe (before heat softens texture), and if you gently press a mature pod/fruit and it feels firm and springy rather than soft, it’s ready to pick.
Botanical illustration of Apollo

Apollo asparagus arrives with a strikingly sweet, clean flavor and a tender, succulent bite—spears that feel silky rather than fibrous. At maturity, the spears emerge in an elegant, upright form with a refined texture that holds its poise whether you enjoy them fresh or turn them into vibrant preparations. Ideal for home gardeners seeking a reliable, long-season performer, Apollo rewards with consistent harvest quality from spring onward.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 35°F before moving outdoors. Harden off for 7 days first.

Expert Note

Plant on a prepared bed with rich compost and keep it weed-free—spears improve dramatically in years 2–3 after establishing crowns.
