Can the catalpa flower sprout if the leaves fall off and the stem is still green?

Even if the leaves of Catalpa have fallen off, the stems are still green and can still germinate. Cultivation techniques:

It likes acid soil

Soil, water and fertilizer contain alkali. Plants cannot absorb iron, which affects the formation of chlorophyll, causing branches to wither, leaves to scorch, and even death. Use fertile, loose, well-drained acidic soil. For example, pine sawdust soaked and mixed into the soil will have good results.

Likes shade

Be careful not to be exposed to the scorching sun, but some people often mistakenly believe that gardenia requires full shade, causing mistakes in cultivation. In fact, they should pay attention to cultivating it in a cool environment. At the same time, 60% of the day's light must be maintained to meet its growth needs.

Moisture-loving

If the air humidity is less than 70%, it will directly affect the differentiation and growth of flower buds, but excessive humidity will cause root rot, branch dryness, and yellowing and falling leaves. Phenomenon. In addition to normal watering, the leaves and nearby ground should be sprayed with clean water frequently to increase the air humidity appropriately.

Like fertilizer

It is advisable to apply fertilized bean cakes, sesame paste residue, peanut bran and other fertilizers. It can become acidic after fermentation, but it must be applied thinly and frequently. Avoid thick fertilizers, raw fertilizers, etc. Fertilizer, no fertilizer during hibernation period. If the planting is less than three years old, avoid applying human excrement. Applying too much nitrogen fertilizer will cause thick branches, large leaves, and dark green, but no flowers. When there is a lack of phosphorus and potassium fertilizers, there will also be no flowering or the flower buds will wither and fall off.

It likes warm temperatures

The growth period is 18-22°C, and the overwintering period is 5-10°C. If it is lower than -10°C, it is susceptible to freezing.

Timely pruning

Gardenia buds form flower buds in April, so in addition to pruning off some redundant branches and leaves between April and May, the focus should generally be on preserving the buds; After flowering, the remaining flowers should be cut off in time to promote the growth of new shoots. When the new shoots grow to 2-3 nodes, the first topping is carried out, and some axillary buds are properly wiped off; in August, the second crop of branches are topping to cultivate the crown and then Plants with beautiful tree shapes can be obtained. Gardenia requires acidic soil with a soil pH of 5-6 to grow well. In northern soil with neutral or alkaline soil, alum fertilizer water should be irrigated regularly or ferrous sulfate solution should be sprayed on the leaves.
