Nursery News for May

1. Spring care for your bonsai: May, a crucial month

May marks a phase of active growth for most bonsai trees, making it a key period for their care. Temperatures rise, the days get longer and the trees wake up to their full potential. Here are the main points to remember:

Watering : keep a close eye on the humidity of the substrate. With the heat, evaporation accelerates. Water generously so that the water penetrates the entire root ball and drains well through the holes in the pot. From the first signs of heat, water every day!

Fertilising : this is the ideal time to feed your trees. Here at the nursery, we use blue universal tomato fertiliser NPK 12 12 17. Use it from April to October, every two months on average. You can alternate with an organic fertiliser (such as horse manure) if you have any.

Pruning : Since the growth is vigorous, prune regularly to maintain the desired shape.

    • For pines, pinch out the stalks;
    • for maples, more severe pruning is recommended. Don't hesitate to clear out the inside to let in the light, which will encourage the reformation of internal buds and better densification. The second growth is generally more resistant to the sun, which improves the overall health of the tree.
    • For flowering trees, remember to clean and prune after flowering to boost their vigour.

Re-potting : this is still possible for some late species, but you need to be quick. Give preference to light interventions.

Pests : inspect leaves and branches regularly for aphids, mites and fungi.

May is also a time for observation: see how your tree reacts to the environment. Each species and each specimen has its own rhythm.

2. Which bonsai to work on in May? Guide by species

Not all trees respond in the same way to spring care. Here's a quick guide to the most common species and the recommended interventions in May :

Deciduous trees (maples, hornbeam, elms, beeches): active maintenance pruning, beginning of binding possible. Watch out for sunburn on young leaves.

Conifers (pines, junipers): avoid severe pruning, but start pinching back young shoots. May is a good time to check vigour.

Azaleas (Satsuki): in full bloom! Don't prune, but start thinking about post-flowering pruning and repotting if necessary.

Tropical bonsai (ficus, zamia): can be taken outdoors if the nights are mild. Prune and fertilise to stimulate branching.

Remember to adapt your work to the local climate and exposure. A bonsai planted facing south will need different care from one in partial shade.

3. Protecting your bonsai from the first blasts of heat

With the arrival of May, temperatures can rise rapidly, especially in south-facing locations. Here are a few tips to avoid heat stress for your trees:

Lightly shade your most sensitive bonsai (young trees, species with delicate foliage) with a veil or shade net.

Appropriate watering : choose two light waterings rather than one heavy one. This maintains humidity without suffocating the roots.

Closer monitoring : soft, yellowing or burnt leaves indicate too much sun or too little water (prune when this happens).

These simple steps will help limit stress and keep your trees in top condition as temperatures rise.

May is also the month of the Japanese festival dedicated to azalea bonsai. These azaleas, called Satsuki, bloom generously between April and June, in shades ranging from pure white to intense pink, including spectacular variegations depending on the variety.

In Japan, enthusiasts gather to exhibit their finest specimens, some of which are several decades old. Satsuki is considered a prime bonsai species for its spectacular blooms and its ability to be finely sculpted.

  • Be careful with watering; azaleas like humidity.
