and are two of the most adored , given the stunning beauty they give off in the summer months.

However, for them to bloom as best as possible, gardeners must know when to give them attention and when not to.

Taking to her page , Polly shared a few absolute no-nos gardeners should be doing in February that lavender and hydrangea owners should take serious note of.

Polly captioned : "Three garden jobs not to do in the garden now this February."

is a key gardening job, but that doesn't mean it should be carried out for all plants all year round.

1. Hydrangea pruning

First up, Polly urged gardeners to "step away" from their hydrangeas with pruning secateurs.

She said: "We are not pruning hydrangeas until the spring. The old faded flower heads act as a nice warm blanket for the hydrangea for the winter. Now is not the time to go ripping it off."

Instead, the pro recommends pruning hydrangeas in spring when there is absolutely no risk of frost.

2. Lavender pruning

The next thing Polly advised gardeners "not to do" is to prune your .

For much the same reasons as the hydrangea, lavender shouldn't be pruned now as the flowers will be past their best.

Polly recognised that lavender plants will be "looking a bit tatty" now, but noted that it's better to prune lightly in spring and go for a harder prune after they've flowered in late August to early September.

3. Sowing many seeds

The third thing you are "not going to do" is sow loads of seeds now because conditions are not yet optimal.

Polly said: "The light levels are still really quite low and this can lead to really leggy seedlings which you don't want to be nurturing for months and months.

"Just hold off and wait for those light levels to get that little bit better - late February or early March."

However, for those who are "really desperate you get sowing now", then some plants you can sow are chillies, cobea scandens - a "really great climber" - and her "favourite" sweet peas.
