Shipping Info
Free shipping on orders of $150+ within the US, including pre-orders. Orders under $150 are calculated at checkout based on size, quantity and destination.
When will it ship?
Live plants ship on Mondays and Tuesdays only, so they never sit in a carrier facility over the weekend. Supplies and pottery ship within 5–7 days; if they’re in the same order as a plant, everything ships together on Monday or Tuesday.
Cold-weather shipping
We only ship live plants when temperatures are 40°F or above. Below 50°F we include a free 72-hour heat pack and ship to arrive within 1–3 days; addresses that need more than 3 days in transit require an expedited upgrade. In the coldest months plant shipments may pause until it warms up.

Product Details
Peters Excel 15-5-15 CalMag Special is the water-soluble fertilizer we've relied on for years. It supplies calcium and magnesium along with balanced nitrogen and potassium, making it ideal for growers using rainwater, RO water or well-flushed media. We feed it to Cattleya, Catasetinae, Paphiopedilum, Phragmipedium, Phalaenopsis species, potted Bulbophyllum and Dendrobium.
For sensitive feeders — Paphs, Phrags and Bulbophyllum — mix ½ teaspoon per gallon every other week and flush with rain or RO water monthly. For everything else, use 1 teaspoon per gallon weekly, dropping to every other week in winter. Flush periodically if you water with tap.
Pair it with our premium potting mixes for healthy, vigorous roots.
