Here are our solutions to the seven deadly sins of plant care.
Almost always this is due to a lack of light. Move the plant to a brighter spot where it does not have to reach for the light.
This is generally caused by a shortage of nutrients so apply a balanced fertiliser to the base of the plant.
Yellowing leaves can also be caused by growing lime-hating plants like rhododendrons or camelias in chalky soil, so replace those acid lovers with something more suitable.
Usually due to dryness at the roots or sun scorch. Water the plant thoroughly and if it is planted in full sun, check that it is suitable for growing there.
If flowers are dropping off unexpectedly, it can be the result of roots drying out during flower bud formation. Remember to keep the soil evenly moist.
The culprit here will probably be slugs or snails and on inspection you can usually see a tell-tale, slimy trail. Copper tape around the rim of flower pots or copper rings sunk into the ground around the base of the plant can act as a deterrent. Alternatively select plants which these pests do not like, find a list HERE.
If a plant is wilting it can be due to either a lack of, or an excess of, water. Make sure that plants are well-watered and do not let the soil dry out for the first month after planting. If you suspect a plant is wilting due to being thirsty, a good soak will usually help it pick up within a couple of hours.
If conversely, the roots of a plant are water-logged, dig it up and move or repot into fresh soil or an area with freer draining compost. If the ground seems permanently water-logged, either try to improve the conditions, or choose plants which are suitable for planting in a bog garden.
This can happen if the roots are being eaten away, generally due to the presence of vine weevil grubs. Biological controls can be used to halt the damage but roots should be inspected to assess the damage and the plant repotted if containerised.
So, with a solution to your sins, may your summer be saintly!
