Agave tequilana

Set it in dry soil at the depth it grew in the pot. Hold off watering for about 1 to 2 weeks in warm weather, or up to a month when it is cool. Then water about every other week while nights stay above 60°F. Light shade cloth for the first few weeks helps it settle.

Water deeply, then let the soil dry before the next soak. About every 2 weeks in summer and every 3 to 4 weeks in spring and fall is plenty. Cut back by October and let winter rain carry it.

Most plants never need fertilizer. If you do feed, use a light balanced fertilizer in spring or early summer, never on a new plant and never in fall or winter. No pruning is needed beyond removing dead lower leaves.

It is hardy to only about 25 to 27°F. On hard freeze nights, drape frost cloth to the ground and remove it in the morning.

It makes abundant pups, some several feet from the main plant. Pull or dig the ones you do not want, and let cut pups dry for several days before replanting.

Drainage test first. Dig the hole and fill it with water. If water is still sitting in the hole a day later, you likely hit caliche, clay or hard soil, so fix the drainage before planting. If it drains very fast, the soil is sandy. Standing water around roots is a common reason new plants fail.

Weed cloth. Cut it away from the planting hole and where the roots will spread. Remove any plastic sheeting completely, since it keeps water and air out of the soil.

Rock or decomposed granite with no soil underneath. Bring in soil close in texture to your native soil, mix it with the soil below, and build up enough depth for roots before planting.

If you can break through. Use a breaker bar, pick, or jackhammer. Dig through the caliche and break out the solid chunks. Backfill with the soil you dug out, with no compost or manure in the hole. Confirm drainage before planting.

If you cannot break through. Dig narrow holes through the hard layer beside the root ball, not under it, and refill them with the same soil, not gravel. If it still will not drain, plant on a low mound of the same soil.

Root ball. Check the outside edges for any roots circling around. Loosen or cut those so they grow outward. Do not break up the center of the root ball.

Depth. The top of the root ball should sit at or just slightly above the surrounding soil level. Planting too deep can lead to rot and kill the plant.

Drip emitters. At planting, put the emitters on the root ball, on different sides of the plant. After about 2 months, move them to the outer edge of the root ball. Over the first year, add emitters farther out toward the edge of the branches as roots grow. Once a plant is rooted, never water only at the trunk.
