1. gardenia like wet afraid of dry
Gardenia suitable for growth in acidic soil, humidity can be in 40-70%, can grow. Potted 7-10 days if not watered will die of drought.
2. Gardenia likes fertilizer
Can often apply water containing ferrous sulfate, alum fertilizer water or corrosive fertilizer can.
3. gardenia resists high temperature
Even in 40 ℃ high temperature also can grow.
4. Gardenia resist severe cold
Even about 10℃ will not freeze to death.
C. Gardenia cultivation method
Gardenia belongs to the flowering not fruit plant, no seed, only by cuttings cultivation.
(1) Cuttings time
The first half of the year is in April and the second half of the year is in August-September. These two periods are the best season for cuttings of Gardenia and the best time for the Gardenia to reproduce.
(2) Gardenia temperature
Generally all are between 15 a 35 ℃, mild climate, suitable for cuttings growth. Generally cuttings can be rooted and sprouted in 30-40 days.
(3) land preparation
Select the land, to choose the land that is more convenient for watering, to ensure that there is a source of watering.
(3) Land preparation
To choose land that is fertile, with loose soil and good air permeability.
(4) Generally before frost
Deep turn the land, through the overwinter frost, can improve the soil.
(5) Gardenia cuttings before
Sprinkle some grass ash, sand, and then turn the land deeply about 30 cm, and then water, you can cuttings.
D. Gardenia cuttings technology
Insert the pruned branches, directly into the prepared ground. Two knots into the soil, leaving the upper end of a section just exposed to the ground as appropriate, and then water it sufficiently.
① Selection of Gardenia branches
Branches should be selected from 1-2 year old branches with good skin color and green leaves free of insect damage.
②Pruning of Gardenia
As the branches have sparse and dense nodes, it is appropriate to keep 3 nodes in general length. Remove the bottom leaves and leave 1-2 leaves in the upper node. Leave the bottom node at 1-2 cm to cut diagonally, and leave the upper node at l-2 cm to cut flat.
Watering once a day in the morning and evening to ensure the humidity of the cuttings, cuttings density of 100-200 plants per square meter.
④Gardenia avoid shade nursery moisture
Gardenia although not as fragile as herbaceous plants, in order to ensure the survival rate should also put up shade trellis, to play the role of shade refuge and moisturizing. Simple methods can be taken locally without cost.
⑤ Around the cuttings
Insert a 50-60 cm stake, erect it with branches and cover it with straw-like mulch. Turn over the mulch at any time on rainy days, and cover again when the sun is strong.
Never apply fertilizer before and after cuttings, especially human, animal, poultry, natural organic fertilizer and urea, chemical fertilizer and the like (avoid drought).
1. Transplanting Gardenia
Seedbed cultivation is the stage that leads to rooting and leaf growth. Due to the high density, it is inconvenient to further cultivate into large seedlings. This requires transplanting and cultivation.
2. Land Preparation
The amount of land depends on the number of Gardenia seedlings, and transplanting density is generally 20-27 cm apart in rows. Plant spacing is 13-17 cm, about 40 plants per square meter.
3. Land preparation and slotting
Draw troughs one shovel wide and 30-40 cm deep at row spacing.
4. Apply sufficient base fertilizer
Fill the trough with soil and fertilizer by mixing 100 kg of chemical fertilizer and 100 kg of phosphorus fertilizer per mu (if you have automatic irrigation equipment, you can use more efficient and fast water-soluble fertilizer).
5. Transplanting time
Generally in the first and middle of March is appropriate. After transplanting, water thoroughly and cover with a layer of fine soil.
Because Gardenia likes humidity and fears drought, water once a week every night after transplanting, and once a week afterwards.
Apply some alum fertilizer water containing ferrous sulfate 2 months after transplanting to replenish iron and prevent the leaves from turning yellow. Can cave apply urea every quarter.
8. Prevent insects
In autumn and winter, foliage spraying drip dread.
