❓ Frequently Asked Questions — Comparing These Plants

Garlic

What are the light requirements for Garlic?

Garlic requires full sun, meaning at least 6 hours of direct sunlight per day, to thrive and produce large, healthy bulbs. Insufficient light can lead to smaller bulbs and reduced yields. When growing garlic indoors, choose a location near a south-facing window that receives ample sunlight. If natural sunlight is limited, supplement with grow lights.

How do I care for Garlic?

Garlic thrives in well-drained soil and requires full sun (at least 6 hours of direct sunlight per day). Plant individual cloves in the fall, pointed end up, about 2 inches deep and 6 inches apart. Water thoroughly after planting. During the growing season, water regularly, especially during dry periods, but avoid overwatering to prevent rot. Fertilize in the spring with a balanced fertilizer to promote bulb development. Remove any flower stalks (scapes) that appear to redirect energy to bulb growth, unless you want to harvest them for culinary use.

How do I propagate Garlic?

Garlic is primarily propagated by planting individual cloves. Select healthy, plump cloves from a mature bulb. In the fall, plant the cloves in well-drained soil, pointy side up, about 2 inches deep and 6 inches apart. Water thoroughly after planting. The cloves will develop roots and shoots over the winter, and new bulbs will form in the spring and summer.

Macadamia

What are the light requirements for Macadamia?

Macadamia trees thrive in bright, indirect light when grown indoors. Insufficient light can lead to leggy growth and reduced flowering and nut production (though nut production indoors is already difficult). A location near an east- or west-facing window is ideal. Avoid placing the tree in direct sunlight, especially during the hottest part of the day, as this can scorch the leaves.

How do I care for Macadamia?

Macadamia trees require bright, indirect light when grown indoors. Direct sunlight can scorch the leaves. Water thoroughly when the top inch of soil is dry, ensuring proper drainage to prevent root rot. Maintain a humidity level of 50-60%, which can be achieved through regular misting or a humidifier.

How do I propagate Macadamia?

Macadamia trees can be propagated through stem cuttings or air layering. Stem cuttings should be taken from semi-hardwood growth in the spring or summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the cutting moist and humid until roots develop.
