Cycads, also known as Sago palms, are a common indoor foliage plant, loved by many for their unique shape and shade-tolerant nature. Proper fertilization is essential for the vigorous growth of cycads. This article will provide a detailed introduction to cycad fertilization methods to help you cultivate a healthy and beautiful cycad.
Understanding the Fertilization Needs of CycadsBefore starting fertilization, it is first necessary to understand the cycad's fertilizer requirements. Cycads have relatively low fertilizer needs, and excessive fertilization can lead to root rot. Fertilization should follow the principles of moderation and balance.
Fertilization TimeThe best time to fertilize cycads is during their vigorous growth period, which is from late spring to early summer. During this period, new leaves of cycads start growing and require more nutrients. In autumn and winter, the growth rate of cycads slows down, and the fertilization frequency can be appropriately reduced.
Fertilization Methods1. Fertilization Amount: The general fertilization amount for adult cycads is 10-20 grams of compound fertilizer per plant per application. If using organic fertilizers, such as decomposed chicken manure or cow dung, apply about 100-200 grams per plant.
2. Fertilization Frequency: Fertilize once or twice a month during the vigorous growth period and once a month during the slow growth period.
3. Fertilization Methods:
a. Broadcast Method: Spread the fertilizer evenly around the cycad and then lightly cover with soil.
b. Trench Method: Dig a shallow trench around the cycad, apply the fertilizer into the trench, and then cover with soil.
Fertilization Precautions1. Ensure the soil is moist before fertilizing to facilitate fertilizer dissolution and absorption.
2. Water promptly after fertilizing to wash away harmful substances in the fertilizer.
3. Avoid direct contact of fertilizer with the cycad leaves to prevent leaf burn.
4. Pay attention to the distance between the fertilizer and the cycad roots during fertilization to prevent excessive accumulation of fertilizer at the roots, which can lead to root rot.
Fertilization Misconceptions1. Over-fertilization: Cycads have low fertilizer requirements, and over-fertilization can lead to root rot and affect growth.
2. Using Unripe Organic Fertilizers: Unripe organic fertilizers contain a lot of harmful substances and can easily cause root diseases in cycads.
3. Using Irritating Fertilizers: Irritating fertilizers, such as ammonium sulfate and superphosphate, can easily cause leaf yellowing and wilting in cycads.
The fertilization method for cycads is relatively simple, but it is important to follow the principles of moderation and balance. Through scientific fertilization, cycads can grow robustly and add a touch of green to the home. During the fertilization process, avoid common misconceptions to ensure the healthy growth of cycads.
