How to prune hollyhocks without affecting their flowering? How many degrees of temperature will hollyhocks not freeze to death in winter?

Hollyhock is also called a hollyhock. Planting it in the ground is the best choice because of its bright colors, large flowers, and sturdy plants. Flowers and plants need to be pruned for better growth and flowering, but improper pruning will affect flowering.

How to prune hollyhocks without affecting flowering

If you only cut off part of the branches when pruning, and do not cut off all of them from the bottom, then buds will still appear on the branches. It will continue to bloom until August, but if you cut it from the bottom, it will take some time for it to grow new branches. It is estimated that it will not bloom this year and will have to wait until next year.

Therefore, when pruning, do not cut off all the branches, at least leave some branches, or cut off some branches with dead flowers, in short, do not prune the branches bare, otherwise it will definitely not bloom.

After pruning off the dead flowers and some branches, loosen the soil, add some phosphorus and potassium fertilizers or other fermented organic fertilizers, a small amount of compound fertilizer, etc., and keep the fertilizer and water sufficient, and water it in time. Hollyhock does not need to be shaded in summer, it is more sun-resistant, so it can continue to bloom.

How many degrees can hollyhocks survive the winter without freezing to death?

Hollyhock is a cold-resistant flower and can safely survive the winter in many places. If the winter temperature is low, you should still take good care of it. Hollyhock planted outdoors is usually safe at low temperatures of -10 to -5°C. Of course, this does not mean that it can grow and bloom at such temperatures.

Under such low temperature conditions, most of the above-ground parts will die, but the stems and leaves close to the ground are still alive. The second year is also the high stems that bloom. If the temperature is too low, you can properly cover it with some cold-proof items, so that you can safely spend the winter.

How to plant hollyhock potted plants

The pot for potted hollyhocks should be large and deep. Because the root system of hollyhocks is very developed, if the pot is too small or too shallow, it will not be conducive to the growth of the plant's root system, the root growth will be restricted, and self-heating will affect flowering.

It is best to use sandy soil with good water permeability for potted hollyhocks, and pure leaf mold should not be used as planting soil.

Hollyhock seeds grow slowly after sowing, and may not even bloom in the same year. It is best to divide and transplant. It is difficult for hollyhocks to survive if they are transplanted after germination. It is best to plant them secretly. Before the hollyhocks germinate, cut the rhizomes with buds from the roots of the ground-planted hollyhocks, and then plant them in pots. When the temperature rises, they will germinate and grow.

Potted hollyhocks need watering and topdressing. It should be noted that the potting soil should be kept dry at all times. Too much water will cause root rot. For potted hollyhocks, the amount of nitrogen fertilizer must be controlled. Try not to use heavy fertilizers, and use more phosphorus and potassium fertilizers, so that the plants will not grow wildly.

Potted hollyhocks must have sufficient light, and should not be placed in the shade. In addition, attention should be paid to seedling control, watering should be reduced in spring, and potassium dihydrogen phosphate should be sprayed on the leaves several times.
