How to Grow Jerusalem Artichokes? Read This Article to Understand the Latest Key Growing Points
If you want to grow Jerusalem artichokes well, you need to know how to handle it at each stage and what tasks need to be done. These tasks are the key points of growing Jerusalem artichokes. I believe everyone thinks their growing skills are still fairly good, but they just feel the yield is not ideal. Once you understand the following few key points, you will know where your problem lies!
1. Suitable temperature
Although Jerusalem artichoke is grown underground, temperature is the key factor affecting its growth. Its temperature requirements differ at each stage. If the standard is not met, growth will naturally slow down, and in the end the yield will naturally be poor. Under normal conditions, Jerusalem artichoke can germinate and emerge at 6-10°C, but only at around 20°C does it expand extremely quickly; once it exceeds 30°C, the rate of expansion in the later stage will slow down. If the temperature fluctuates greatly during this period, its growth will also be affected. This is how severe the impact of temperature is on Jerusalem artichoke.
2. Sowing
Actually, everyone does not pay much attention to sowing Jerusalem artichoke, always thinking this is a task with no technical content, but in fact sowing is very important. From the planting spacing of the tubers, to the planting depth, to the degree of covering with soil, all of these are quite particular. If done too casually, mistakes are easy to make, leading to a lower emergence rate. When sowing, the sprouting side should face up, the soil used for covering should be crushed, and the soil does not need to be compacted. These problems are easily overlooked by growers, because once sowing takes a long time, everyone becomes somewhat numb to it and is not as careful as at the beginning.
3. Topping
Growers rarely do the process of topping, and many simply give up on this step because they feel the labor input and returns are not proportional. In fact, after topping, the expansion speed and size of Jerusalem artichoke will be noticeably greater than before, and the quality will also be better. Therefore, if growers face greater competitive pressure, they might as well top the plants to make their Jerusalem artichokes more competitive. If it really feels too troublesome, then at the very least the Jerusalem artichokes kept for seed need to be topped, leaving a batch of good seeds for subsequent planting.
4. Topdressing in stages
The fertilization stage is also relatively important, but fertilization cannot be done arbitrarily, otherwise it is harmful rather than beneficial. When fertilizing Jerusalem artichoke, it is important to do it in stages, that is, special attention must be paid to what fertilizer needs to be applied at what stage. Fertilization is mainly concentrated in two stages. One is the seedling growth period; fertilizing can help it quickly pass through the growth stage, and nitrogen fertilizer has a more obvious effect at this stage. During the expansion period of Jerusalem artichoke, potassium fertilizer has a better effect, and this is also the second fertilization stage.
The above are the key points for growing Jerusalem artichoke. If you want to grow Jerusalem artichoke well, many issues need to be handled carefully. Growing is about being more meticulous than others, and then your returns may be higher.
