There are many variants of hydrangeas to choose for, and you can certainly grow several types of them in a single garden. This, however, is more easily done if you are located in the ideal region.

Most gardening experts consider zones five to nine as the ideal places to grow hydrangeas, which can reach heights anywhere between three to six feet. Moreover, if you are located in an area that is prone to receiving extreme heat, then make sure that you grow your flowers in a part of the garden that receives maximum shade. Hydrangeas do not like the heat much.

In any case, if you wish to grow hydrangeas, making sure that they have organically supplemented and well-drained soil would definitely help prevent you from suffering gardening woes.

When to Plant

It is ideal to wait for frost to completely disappear before planting hydrangeas, and that would be around spring time. After planting your first hydrangeas, do make sure that you give them a thorough watering session. It would also help if you add a good amount of mulch to your soil. All in all, adding fertilizer 1x or 2x a year would also be a big help.


Since these flowers do not like heat, it only makes sense that, conversely, they have a deep love for watering. It would be ideal if you give these blooms deep watering weekly and especially so if you live in an area that has extremely hot or dry weather.


If there is any need

to transplant your blooms to another area in your garden or home, make sure that you do so only when they have reached a period of dormancy, which would fall around autumn or winter.

Make sure that you dig out its root ball or root system in its entirety. You must also not waste any time replanting them.


There are only three things that you could have done to prevent hydrangeas from blooming beautifully. Firstly, you planted them when there is still a threat of frost. Although hydrangeas do not like the heat, they will not grow in extremely cold conditions either. And of course, heat is the second reason - too much of it would prevent your hydrangeas for filling up your garden with stunning colors.

Last but not the least is pruning - if you prune too early then your hydrangeas will not bloom as they should. Unfortunately, pruning is one particular aspect in which the rules differ from one variant to another. Consider the examples of different pruning schedules and requirements below.

  • Oakleaf hydrangeas should be pruned in the early days of spring for optimal year-long growth.
  • Panicle hydrangeas require a bit more complex pruning. Firstly, they benefit from early spring or late winter pruning. Secondly, it is critical that you take out spent blossoms whenever you see one.
  • Hydrangea vines, which are also known as climbing hydrangea, need only be pruned if you are having trouble controlling newly grown blooms
  • Lacecaps and mopheads are best pruned in the summer.
  • Hills of Snow is a variant that has to be pruned either early spring or late winter as well.

Changing the Color of Your Flowers

It will require you to play the role of a scientist in some ways, but if you really want a particular color for your hydrangeas then that can be easily arranged. Big leaf hydrangeas can be grown to acquire blue or pink petals based on certain conditions.

Pink Hydrangeas occur because there is no sufficient source of aluminium in the soil, which could be due to the fact that you are growing them in pots. Soil should also have their pH levels around 6.0 to 6.5. You can add dolomitic lime if necessary. Fertilizers with high phosphorus content are also ideal as they limit the presence of aluminium in your soil.

Blue Hydrangeas require the opposite or high level of aluminium in your soil. It has to be slightly acidic, with pH levels around 5.2 to 5.5. For fertilizers, choose those that are low in phosphorus but high in potassium.
