Safety Warnings

Be mindful of poisonous hairs on certain plants like some Primulas which may irritate the skin.

forceful water spray — clear water pump or city water spray

thrust-hoe — stainless steel

summer mulch — old hay, leaves, rough manure, or grass clippings(as needed to cover soil surface)

shading material — muslin or wooden slats(sufficient to cover flower beds)

Prepare the soil by keeping cultivation very shallow once plants have established to avoid disturbing roots during heat.

Tip: Ensure ground is clean before applying mulch.

Apply a midsummer mulch of hay, straw, leaves, or grass clippings to the soil surface.

Tip: This helps control weeds and prevents the soil from drying out.

Maintain consistent moisture and provide shade during the hottest parts of the day.

Tip: Shade is an essential requirement for successful growth through a hot summer.

Install light shading using muslin or slats above beds for flowering plants if the weather is very bright.

Tip: This prolongs the duration of the flowers.

Manage pests, such as those affecting roses, by applying a forceful spray of clear water early in the morning and again in the evening.

Tip: This is an effective method for keeping summer pests in check.

Perform light pruning on stronger branches that have already flowered to encourage new growth and flowers.

Tip: Cut back one-half or more of the branches.

For those growing lettuce in summer, use heat-warrior varieties like 'Nevada' batavian to prevent bolting.
Leafy vegetables such as beet, cabbage, and Swiss chard are more satisfactory in gardens with some shade.
