Plant Care & Growing Tips

Unlike many plants , Astilbe does not need full sunshine to farm its beautiful flowers – in fact , it favours the wraith .
It will , however , benefit from a footling Dominicus , to avail it produce expectant blooms .
The best location to choose for it is one of partial or dappled refinement , with perhaps an hour or two of sun throughout the day .
Soil Requirements

Astilbe can tolerate all types of grime – including acidic – with the exception of wry ground .
As it needs a high moisture depicted object , it will also do well in a boggy or waterlogged spot , where many other plants might struggle – for case by a flow or pool .

Astilbe is a hardy plant , and apart from lachrymation , requires little ongoing care for it to flourish and flower each time of year .

you’re able to add a slow - release , balanced fertiliser at this time , to aid the summer ’s flowering .
Common Problems
Astilbe is generally not prostrate to disease .
One possible concern is powdery mildew , particularly due to Astilbe ’s love of damp , shaded grow locating .
Powdery mildew is a fungal contagion which can lead to a powdery ashen coating on your plant ’s leave of absence and flower , as well as distorted leaf growth .
To aid avoid powdery mildew , make certain not to over - fertilize the ground , and do n’t plant too thickly , as this will stop air from circulate around your plant life , encouraging the conditions for mould .
Pruning back the centre of the industrial plant or the sectionalisation of a dumb plant can also help as this will help to increase tune circulation .
If your plant shows signal of contagion , you may undertake it by immediately pruning the unnatural areas , and removing any fallen infected material on the ground .
you may also utilize a fungicide .
Another disease that may pretend Astilbe is Bacterial Leaf Spot .
The most obvious symptom of this is black or brown dapple on the folio .
Unfortunately , it is not possible to all eradicate Bacterial Leaf Spot once your plant is infected , but it can be controlled with the usance of a fungicide .
There are not many pestis mutual to Astilbe industrial plant , although vine weevil can sometimes attack with notches in leaves becoming evident .
from time to time , they might succumb to an infestation of tarnished plant bug – a 5 mm , yellowy - brown bug , that feed on plant tissue paper , nurse juices from leaves and shoots .
These bug can be controlled using insecticides , or by applying a garlic spray to your flora , to admonish feeding .
You should also remove weeds and dead leaves from the area around your works , so the bugs have nothing else to feed on , and nowhere to obscure over wintertime .
When you first establish your Astilbe , you may notice hedgehogs and rabbits nibbling on the leaf , but once the plant is established , it is by and large fairly tolerant to becoming wildlife fodder .
