How often should indoor houseplants be watered in winter?

Most tropical houseplants reduce their transpiration and growth rate significantly during late autumn and winter due to lower light levels. The general rule is to reduce watering frequency by 40-50% compared to spring and summer. Always perform the 2-inch finger moisture test: insert your finger 2 inches into the compost and only water if the substrate feels completely dry.

When and how should I prune Wisteria in the UK?

Wisteria requires a two-stage pruning regimen to flower prolifically: (1) Summer Prune in July or August: cut back the whippy green current-season shoots to five or six leaves (approx. 15-20cm); (2) Winter Prune in January or February: cut back those same shoots further to two or three dormant buds (approx. 5-8cm) while the plant is fully dormant.

Why do houseplant leaves turn yellow with brown crispy tips?

Brown crispy tips paired with yellow margins are usually caused by a combination of low ambient humidity (common in centrally heated rooms) and uneven watering, or tap water mineral accumulation (chlorine and fluoride). Increasing humidity with pebble trays and allowing compost to dry slightly between thorough soakings will resolve the issue.

What are the three RHS pruning groups for Clematis?

Clematis are divided into three RHS pruning groups: Group 1 (early spring flowering like Clematis montana) requires minimal pruning immediately after flowering in late spring. Group 2 (large-flowered cultivars blooming in May-June and again in late summer) requires light shaping in late February. Group 3 (late-flowering like Clematis viticella) requires hard cutting back to strong pairs of buds about 30cm (1ft) above ground level in February.

Which popular indoor houseplants are safe for cats and dogs?

Pet-safe indoor houseplants include Calathea (Prayer Plants), Boston Ferns (Nephrolepis exaltata), Spider Plants (Chlorophytum comosum), Peperomia varieties, Parlor Palms (Chamaedorea elegans), and Phalaenopsis Orchids. Plants containing insoluble calcium oxalates (such as Monstera, Philodendron, and Peace Lilies) should be kept out of pets' reach.

English Shrub Roses (David Austin / Heritage)

Rosa gallica / hybrida

Pruning Window: Late Winter / Early Spring (mid-February to early March in UK)

Pruning Group: RHS Shrub Rose Renewal

Pruning maintains an open, goblet-shaped bush with vigorous new basal canes and abundant fragrant blooms.

Step by Step

Remove the Three Ds: Cut out all Dead, Diseased, and Damaged stems right down to green healthy tissue.
Shape the center: Cut away crossing branches and twiggy weak growth to create an open center for airflow, discouraging black spot and powdery mildew.
Reduce height: Shorten the remaining strong stems by one-third to one-half, making clean sloping cuts 5mm above an outward-facing bud.
Deadheading in Summer: Throughout June to September, deadhead spent flowers down to the first strong 5-leaflet leaf to prompt rapid reblooming.

Tools Required

Gauntlet rose gloves, Heavy-duty bypass secateurs, Pruning saw for old woody stems

RHS (UK) Notes

Essential for traditional British cottage gardens and conservatories. Treat with uncleansed organic horse manure mulch in March.

USDA (US) Notes

USDA Zones 4–9 depending on cultivar. In cold winter zones, delay pruning until forsythia is in bloom.
