June: the month that defines how your garden will look in summer

June marks the start of the Mediterranean summer and is probably one of the most important months of the year for any gardening enthusiast. After a spring of intense growth, plants begin to prepare themselves for the hottest weeks ahead, with soaring temperatures, more hours of sunshine, and an increased demand for water.

In Ibiza, where the Mediterranean climate can be particularly demanding during July and August, taking action now is essential. A well-tended garden in June will be a more resilient, healthy, and sustainable garden throughout the summer.

Below, we run through the main gardening tasks for June, tailored to the conditions of Ibiza and Formentera.

1. Feeding: strengthen your plants before the heat arrives

Feeding in June is key to helping plants cope with the heat stress of the coming months. A balanced supply of nutrients promotes healthy growth, strengthens roots, and improves the plants' ability to withstand drought.

What type of fertiliser should you use?

We particularly recommend:

• Organic compost

• Worm cast humus

• Well-rotted manure

• Potassium-rich fertilisers

Potassium is especially important at this time of year, as it strengthens plant tissue and improves resistance to heat, water shortage, and certain diseases.

When should you apply fertiliser?

Ideally, feeding should be carried out during the first few weeks of June, taking advantage of the fact that plants are still in an active growth phase.

Eiviss Garden Tip

After applying any fertiliser, water copiously to facilitate nutrient uptake and prevent potential root burn.

2. Planting: choose hardy Mediterranean species

June is still a great time to introduce new plants to the garden, especially if you select species that are well-adapted to our climate.

Mediterranean plants offer a major advantage: they require less water, cope better with high temperatures, and generally need less maintenance.

Recommended trees and shrubs for Ibiza

Trees

• Olive

• Carob

• Almond

• Pomegranate

As well as bringing shade and structure to the garden, these species are perfectly adapted to the island's conditions.

Mediterranean shrubs

• Lavender

• Rosemary

• Santolina (cotton lavender)

• Mastic (lentisc)

• Westringia (coastal rosemary)

• Phillyrea angustifolia (narrow-leaved mock privet)

These species provide beautiful blooms, fragrance, and excellent hardiness during the hottest months.

Flowers to fill your summer with colour

If you are looking for long-lasting blooms and low maintenance, we recommend:

• Lantanas

• Gazanias

• Agapanthus

• Salvias

• Gaura

• Vincas (periwinkle)

At our production nursery in Santa Gertrudis, we grow most of our local "km 0" stock, selecting species that are uniquely adapted to the climate of Ibiza and Formentera.

3. Optimise your irrigation before the heatwaves start

One of the most common mistakes is waiting until July to check the irrigation system.

June is the perfect time to ensure everything is running smoothly.

Check for:

• Clogged drip emitters

• Automatic timers/controllers

• Water leaks

• Misaligned sprinklers

• System pressure

An efficient system not only improves plant health but also helps to reduce water consumption—an increasingly vital issue on our island.

Mulching: your best ally

Adding a layer of organic mulch around your plants helps to:

• Retain soil moisture

• Reduce evaporation

• Suppress weed growth

• Keep root temperatures more stable

4. The kitchen garden in June: one of the most productive months of the year

The vegetable patch bursts into full action in June and requires a little care to guarantee bountiful summer harvests.

What to sow in June

These varieties perform exceptionally well in the warm summer temperatures:

• French beans

• Cucumbers

• Courgettes

• Basil

• Rocket

• Radishes

• Parsley

What to transplant

If you have started young plants in plug trays, now is the time to plant them out into their final positions:

• Tomatoes

• Peppers

• Aubergines

• Melons

• Watermelons

Important

Set up stakes, trellis, and support systems before plants grow too large. This will prevent damage later and make maintenance much easier.

5. Summer lawn care

Lawns are one of the areas that suffer the most during the hot months.

Preparing your lawn properly in June can make a world of difference for the rest of the summer.

Mowing height

Avoid mowing too low.

Keeping the grass slightly longer:

• Reduces water evaporation

• Protects the root system

• Minimises drought stress

• Promotes a more even green colour

Efficient watering

It is much better to carry out deep, less frequent waterings rather than light daily sprinkles.

The best times to water are:

• Early in the morning

• Late in the evening

Fertilisation

Use specific summer fertilisers, preferably slow-release formulas, which supply nutrients gradually without encouraging excessive surge growth.

6. Keeping an eye out for pests and diseases

With rising temperatures, some of the most common issues in Mediterranean gardens begin to appear.

The most common pests in June

• Aphids

• Mealybugs/scale insects

• Whitefly

• Red spider mite

• Thrips

Early detection is vital.

Regularly inspect:

• Young shoots

• The undersides of leaves

• New growth

• Plants most sensitive to the heat

The sooner a pest is spotted, the easier it is to control.

7. Caring for houseplants

Although we usually associate June with the outdoor garden, indoor plants also need a few adjustments during this season.

Boost ambient humidity

The use of air conditioning can dry out indoor air significantly.

Some simple solutions include:

• Misting the leaves

• Using humidifiers

• Placing pots on trays filled with water and pebbles

Check the compost

If you notice that the potting mix is highly compacted or depleted, this is a great time to partially top up or refresh the substrate.

Houseplants that especially appreciate this care

• Monstera (Swiss cheese plant)

• Ficus

• Pothos (Devil's ivy)

• Calathea

• Strelitzia (Bird of paradise)

• Philodendron

Sustainable gardening: the key to future gardens

An increasing number of clients are looking for gardens that combine beauty, resilience, and reduced resource consumption.

That is why, at Eiviss Garden, we recommend choosing:

• Mediterranean plants

• Efficient irrigation systems

• Natural mulches

• Organic soils and fertilisers

• Species adapted to the local environment

Small decisions that make a huge, positive impact on both your garden and the environment.
