How to water the Luisa Grass
The Luisa herb does not need much water, it is clear that in the summer it will have greater need of it but the only way to understand it is to insert the fingertips of the hand in the earth where it is planted to understand if it is dry or still damp. If the soil is damp, it will be a good idea to wait before adding more water, but if it is dry, immediately water the soil where the plant lives. However, there are small green thumb tricks to see if the herb Luisa is thirsty or not. In fact if you notice the yellowed leaves it means that it receives too much water, but if the apices wither it means that it receives too little. It is difficult to establish a precise irrigation frequency because there are many variations, such as the season, the place where the plant is placed and the temperature. As with any plant it is good to keep a saucer if the Luisa herb is inside the house so that the earth throws away the extra water and remember not to water too close to the ground to avoid uncovering the roots and making furrows on the ground.
How to cultivate and care for the Luisa herb
The Luisa herb is a plant that hardly tolerates cold, therefore it is advisable to plant it in a point of the garden always exposed to the sun and away from rain and wind or better to cultivate it in a pot and keep it indoors. If the plant is outside and it is winter frosty, protect the plant with clear plastic. In any case, the Grass Luisa loves the moist soil and is always hydrated especially in periods of drought but be careful not to overdo it. It is important to feed the plant every three or four months with granular fertilizer for green plants. If the plant is grown in pots, it will be repotted in a larger one when the roots come out of the drainage holes of the pot. Treat the Luisa grass by cleaning it from dry and damaged stems as well as from dry and yellowed leaves.
How and when to fertilize the Luisa Grass
A good granular fertilizer is essential to nourish and fortify the Luisa Grass at least three or four times a month. It should be mixed with the earth that receives the plant and immediately irrigated. The ideal time to fertilize is the beginning of spring until September - October. In winter only indoor plants should be fertilized, if kept in heated rooms or in areas of the house repaired, such as on the veranda, because they continue to grow, which is why important nutritional support is needed. Pay attention to the constancy and regularity of the water and fertilizer supplies: supplies that are too far apart over time can in fact cause damage to the plant and give rise to null results in terms of vegetable well-being, and obviously also in terms of aesthetic or productive satisfaction.
Erba luisa: Diseases and possible remedies
Grass Luisa is not a plant that suffers from particular fungal diseases. Rarely or in any case when the weather is particularly humid does it fear the attack of ladybugs or animal parasites such as aphids in general. They should be treated from the first symptoms of pest infestation with pyrethrum-based products and the treatment should be repeated several times during the spring-summer period. Avoid spraying medicinal products so as not to kill insects useful to the environment and to the plant itself, but prefer the hydration of the plant by pouring the diluted substances with water on the plant, especially on the tips. Like all plants, it can suffer drought and alarm bells are withered apexes, or it can rot due to excessive water and the first symptom is the yellowing leaflets. So pay attention to the hydration of the plant, especially during the summer.
