Goldfish grass is a colorful girl's dream

To make the goldfish grass burst in the pot, the core is sufficient light, timely heart picking, frequent application of thin fertilizer, and post flower pruning. By achieving these points, round and full flower balls can grow Choosing the right variety is the first step Dwarf varieties: such as Thumb Fairy Child and Flower Rain series, with a plant height of 15-25cm, suitable for potted cultivation, with a long flowering period and easy management. Avoid tall varieties: Poetic F1, suitable for planting in flower beds, potted plants are prone to lodging and not aesthetically pleasing. Soil and pot selection Flower pot suggestion: Red pottery or green mountain pots with a diameter of 15-20cm, depth ≥ 15cm, and 3cm ceramic particles placed at the bottom of the pot to enhance drainage. Soil mixing formula: 4 parts peat soil+2 parts perlite+1 part decomposed pine scale. Add 3g of Aolv 318s slow-release fertilizer as base fertilizer per liter of soil. Key points: The soil must be loose and breathable. Goldfish grass is most afraid of water accumulation and root rot. The garden soil is prone to compaction and must be replaced. Lighting and Temperature Management Light requirements: Full day sunlight in spring, autumn, and winter, with at least 6 hours of direct sunlight per day. The more light there is, the shorter and stronger the plants will be, and the more vibrant their colors will be. Summer shade: Pull a 50% shade net from 10:00-16:00 to prevent the leaves from being sunburned into "caramel pudding". Suitable temperature: The golden temperature for growth is 15-20 ℃, and it can tolerate low temperatures of -5 ℃. It is recommended to sow in autumn for one-year or two-year cultivation in high temperature areas in the south. Watering techniques Watering principle: When dry or wet, the soil surface should be 1cm dry before watering thoroughly. After soaking in the pot for 5 minutes, the tray should be emptied of accumulated water. Frequency reference: Water thoroughly once every 3-5 days in spring and autumn; Watering in the morning and evening in summer, once every 2-3 days; Once every 7-10 days in winter. Taboo reminder: Do not let the leaves get wet, avoid water accumulation in the soil, and do not water at noon in summer, otherwise it is equivalent to "sauna". Fertilization plan Growth period: Apply compound fertilizer (diluted to 0.01%) every 10 days from seedling to pre flowering to promote lateral branch germination. Pregnancy period: Apply potassium dihydrogen phosphate (0.1% solution sprayed on leaves or roots) to promote large and colorful flowers. Attention: Goldfish grass has rhizobia that fix nitrogen. Apply less nitrogen fertilizer to avoid excessive growth and lodging; Stop fertilizing and save life when the high temperature exceeds 25 ℃. Trimming Heart Picking Tips First Heart Picking: When the seedling height is 10cm, top it and leave 4 leaves to promote lateral branch germination. This is a must-have for dwarf seeds. Pruning after flowering: Cut off the remaining flowers along with the 3 pairs of leaves below, light pruning is sufficient, heavy pruning may damage the "nursing home", and new branches will bloom again after about 2 weeks. Daily cleaning: Cut off diseased, old, and overly dense branches in a timely manner, maintain ventilation and light transmission at the bottom to reduce pests and diseases. pest control Gray mold: When the flowers grow mold spots, spray 1000 times diluted mancozeb solution and cut the diseased leaves simultaneously to ensure ventilation. Root rot disease: Dig out the rotten roots and cut them into healthy parts. Soak in carbendazim 1:800 for half an hour, then replace with peat and perlite 7:3 new soil to regenerate. Pest control: Aphids/spider mites sprayed with imidacloprid or soapy water; Spray substitute zinc after cutting the diseased leaves of powdery mildew.
