This week in the garden: Jan 24-30

Try grafting new fruit tree varieties onto your existing trees. Fruit of the same species are easily grafted together - peach onto peach, plum onto plum.
Tasks
- · Irrigate citrus and almonds at night if frost is expected.
- · Apply pre-emergent herbicide in early February to flower beds and water-permeable paths.
- · Provide frost protection. Move or cover tender plants. Use floating row covers or fabric and uncover plants during the day. Plastic is not recommended.
Pruning
- ·· It is now or never for pruning hydrangeas. Remove a third of the old wood for maximum bloom.
- · Prune evergreen shrubs such as pittosporum, podocarpus, euonymus, lavender, sage, buddleja, rosemary.
Fertilizing
- ·· Apply one third of the needed annual amount of fertilizer to deciduous fruit, nut, and citrus trees. They need feeding two to three weeks before bloom.
- · Fertilize annuals and perennials that were planted in the fall.
Planting
- · Make certain a plant’s basic sun and shade needs are considered before planting.
- · Bare root planting season ends in early February.
- · Perennials: Lenten Rose (Helleborus), Salvia ‘Rose Pink’ (Salvia greggii), Euphorbia ‘Ascot Rainbow’, Euphorbia ‘martini’.
- · Perennial Grasses: Needle Grass (Nassella), Pink Muhly (Muhlenbergia capillaris), purple fountain grass (Pennisetum setaceum ‘Rubrum’).
- · Fruits and vegetables: potatoes and rhubarb.
- · Annuals: phlox drummondii, plant from seed.
- · Trees, shrubs, vines: sweet gum (Liquidambar), Chinese pistache (Pistacia chinensis), Chinese tallow (Sapium sebiferum).
Enjoy now
·· Annuals and perennials: annual phlox drummondii, sweet peas.
· Bulbs, corms, tubers: hyacinth (Hyacinthus).
· Trees, shrubs, vines: forsythia.
· Fruits and vegetables: navel oranges, spinach, chard.
Things to ponder
· In years when rainfall is below normal, consider planting drought tolerant plants. Look for native or Mediterranean labels.
· When forsythia begins to bloom, apply pre-emergent herbicide to your lawn to prevent crabgrass.
